Abstract

A hybrid disc whose ROM grooves are less than 170 nanometers deep, and whose pre-recorded ROM data pits are more than 350 nanometers or less than 250 nanometers deep, as measured from the effective land level. The ROM pits may be pre-recorded in ROM grooves that are shallower than the ROM pits, where the ROM pits are narrower, of equivalent width or up to approximately 10% wider than the ROM grooves, respectively measured at half-depth, although the transverse extent of the ROM pits will not typically exceed that of the ROM grooves. The ROM lands intervene between consecutive ROM pits, whether or not a ROM groove is provided. In the preferred embodiment, one beam of a dual beam apparatus records the ROM pits, while the other beam records the R-band pre-grooves, and also records the ROM groove, if present. In most embodiments a thermal mastering process provides smooth feature surfaces to facilitate replication of the hybrid disc masters. The berms normally forming at the radial extremities of the pits and grooves in the masters, by thermal expulsion processes, may be reduced or eliminated by methods taught.

No. 09/558, 〇71 continued the application. FIELD OF THE INVENTION The present invention relates to an improved hybrid optical recording disc and a method for manufacturing such a disc. ^ 10 Printed by the Intellectual Property Office of the Ministry of Economic Affairs, Consumer Cooperatives 20 25 Prior art Recordable discs (CD-Rs) and recordable digital video and audio discs (dvds-if) are well known in the industry. In recent years, a less well-known new DVD-R has been introduced, but practitioners familiar with this technology are also familiar (or will soon ^ this format. In any of these formats, by A large amount of data typically represented by a long, three-dimensional sequence of symbols in a spiral-shaped channel surrounding a disc can be achieved by rotating the disc at a constant linear velocity (,, αν〃) and enabling a selectively controlled mine射束 指 提 # Optical recording is performed in a pre-grooved manner in a recording layer near one of the substantially flat surfaces of the disc. For simplicity, the following sections will focus on the CD_R format, but will sometimes be mentioned ]) VD-R format. Those skilled in the art will understand the differences between them, and how to properly understand how this manual applies to any hybrid disc format based on the way in which data is represented by tiny three-dimensional symbols. ,, and, for the sake of clarity, some dimension conventions will be used in the following:,, 'service direction or ,, horizontal means ,, radial direction from or toward the center of the disc.

Description of the invention (2 10 15 The Ministry of Intellectual Property Bureau ’s Consumer Cooperative Cooperative printed 20 25 the trailing edge. The vertical direction is orthogonal to the radial direction on a microscopic scale, and these two axes are parallel to the disc surface. Therefore, one is on the plane of the disc The measurement of the inner transverse to the longitudinal direction will be within the radial direction. ,, vertical 〃 means,, orthogonal to the disc surface and orthogonal to the radial and longitudinal directions. The recording layer includes a color and a write laser. The complementary color dye is covered by a reflective metal layer (this layer is usually covered by a final protective layer) to reflect the laser beam energy back into the recording layer. The beam passes orthogonally through the disc The second surface of the substrate is burned 〃) to create a data number in a recording layer near the reverse surface. This substrate is a suitable transparent material (usually polycarbonate). According to the tradition, in the case of CD-Rs, enter The data goes from eight to fourteen (EFM) modulation. In this process, sequential binary input data (information to be burned and subsequently retrieved has been transformed into such data) is transformed into a series of spaced apart rectangular pulse waves. The duration of each pulse wave is nT, where τ is the nominal clock period, which is approximately 231 nanoseconds (billionths of a second), and n is an integer from 3 to Π. In the case of j) VD-Rs, use,, efm Plus〃 modulation method. The important differences from EFM modulation are: (1) modulation method using eight bits to sixteen bits; (2) the integer n can be 3 to u or 14; and (3) Tf38 nanoseconds . Each EFM or EFM Plus encoded data stream will always contain pulses and intermediary short time spans including all possible nT durations. As is well known in the industry, the interval between each transition (pit to flat (_) or flat to pit) and the next subsequent transition individually represents a quantum of data. Therefore, each data pulse wave and each intermediary ground plane is nT = interval ', and within each data stream, all permitted η values must be presented within both the pulse wave and intermediary = ground. In the past, other modulation schemes were used or proposed, and in the future, there will be no doubt that other viewing methods will be used, because the optical record-4-this paper size is suitable for financial standards_CNS A4 size (21 {) χ 29? Public binding line 200419559 A7 B7 V. Description of the invention (3) The data density on the disc is inevitably increased. However, it should not be difficult to deduce from this specification a plan that covers any of these general engineering modifications. In the case of CD-Rs or DVD-Rs, which are the primary objects of this specification, each data record burned onto a spiral pre-groove in the recording layer includes a series of 5 unmarked or different marks inserted. Lots of tiny three-dimensional marks on the ground. However, the present invention is also applicable to mastering of hybrid rewritable media, such as CD-RW hybrid discs and magneto-optical (M0) discs, where the data marks are essentially two-dimensional (but Except for the ROM symbol in the CD-RW master and the copyable bluff in the MO disk). CD-RW hybrid discs and boat discs will be mentioned shortly below. The holding distance (that is, the radial distance between the longitudinal axes of adjacent generally circular running parts) is small, as is the length and width of each mark. 、、 ATIp " (absolute time in pre-groove) The timing data is broadly added to the original smooth spiral road. In the case of CD, this ATIP 15 o'clock data contains a time of 22.05 kHz (standard (Nominal value) Modified radial sinusoidal carrier wave with an amplitude of ± 30 nm (nominal value) relative to the longitudinal axis of the pre-groove without flutter / spiral. The data in the printed record layer of the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, despite its ATIP chatter and its inevitable spiral structure, can be regarded as a large number of closely spaced roughly circular paths, each path containing 20 A large number of continuous three-dimensional data marks and intermediary flat. In some applications, a particular piece of information or instruction may not be a complete circle. In a sense, it may only occupy an arc of a circle on the disc. However, in this description, the circular and circular data tracks or parts of the tracks are interchangeably referred to as circular data holders. Because the perimeter of each of these roughly circular paths is 25 times larger than the size of the mark and the land, a small series of marks and intermediary flat ground will look like a linear paper on a microscale.

Description of the invention (4) 5 10 15 A member of the Intellectual Property Bureau of the Ministry of Economic Affairs and the Consumer Cooperative printed 20 (that is, a straight line) sequence. Therefore, at the micro-scale, the radially adjacent data on the disc can be regarded as roughly parallel data lines. Each data line contains a longitudinal series of linear marks and flat land, but at the macro-view scale it is roughly Concentric circular path. The appearance of the data mark is usually like a long, abdomen-shaped two-dimensional mark constrained between the reflective layer and the substrate in a prefabricated groove. Each mark contains at least one of a substrate and a reflective layer that is distorted. The difference between the material characteristics of the burned mark and the unburned area in the recording layer is that the refractive index of the material in the mark changes due to the application of a modulated laser beam, and additional physical and chemical changes also occur. The intensity of the laser beam is adjusted according to the coded data to be burned, and each obtained mark and each agent flatly represents a part of the data. In the CD-R burning operation, each data mark and flat run length corresponds to a pulse with a duration of 3T to 11T. Thanks to the use of CLV, all symbols corresponding to the same ηT value and ideally the same length. Once the programming is completed, the f-material may be selectively retrieved (also decoded and processed) by the CD player in Suixian. Ideally, a CD player will not be able to distinguish data tokens read from —GD—R or from CD-ROMs (CD.M, such as software CDs), so data can be retrieved from each format in the same way. Different, writing strategies ", that is, the data signal modulation architecture (for example, a degree of specified amplitude enhancement) can be used to control the final laser beam intensity (ie, the coded data signal related to the machine number. These It is hoped that the leading and trailing end will be created with three-dimensional data marks with appropriate lengths and peacefully to ensure quasi-high frequency (HF, that is, expected) retrieval by minimizing the secret county error. The latter depends on the accurate measurement of the length of each mark-the amount of lunar edge-land-land-to-land transition zone to its trailing edge-land 25

And measure the length of each-flat ground from its leading edge mark-flat ground transition area to the edge of the basin end flat-mark transition area, and then transform these lengths into corresponding nT values. If the mark is flat and symmetrical in three dimensions and has an appropriate length, the HF search can be facilitated by being able to choose-a specific reflectance, which will then correspond to any 5 points of transition. Since CD-Rs and CD-ROMs are expected to be read interchangeably in a CD player, although GD-Rs must be compliant with Phillips-Sinli, 'Cai Shushu (Wrist-Sony, Orange Book)' ） Specifications and 〇) —Ribbon must conform to, Red Book // Specifications, this writing strategy adjustment of coded data signals ^ 10 to ensure that the player cannot detect a CD-R or CD-R0M Any differences between them are important. These Philips-Sinli regulations are well known to those skilled in the art. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, as mentioned earlier, optical discs are usually made by A motor-driven mandrel uses the CLV to rotate rapidly for programming and subsequent reading. (I may notice that some players use a constant angular velocity playback system, but this manual uses 15 CLV for programming and playback.) Sacking—The effect of accurately maintaining the radial position of the writing beam and / or reading beam at the center of the data beam is achieved by a servo device that compares consecutive readings of at least a single pair. In CD-R players, usually Use a single beam (,, push-pull: ,, PP ") for the effect. The reflected beam is optically separated into a data retrieval beam and a pair of beams. 20 In CD and DVD-R applications, The reflection beam component of the roughly circular cross section is divided into two equal semicircles, and the separation line between the two semicircles is parallel to the longitudinal execution axis, that is, obtained on two opposite sides of the longitudinal axis of the execution. The readings of the pair are compared with the intensity of the two halves of the image, and a servo mechanism adjusts the radial position of the beam so that the light sensed by the two halves is equal. The latter state 25 represents The reading is taken from the center of the execution axis, that is, the correct application of the Chinese National Standard (CNS) A4 specification (210 X 297 mm) to the paper size has occurred. 200419559 A7 B7 V.

In the single beam CD operation, one of the two components is sensed. Minus another eight 1 and zero difference The value (that is, the inputs from both sides are equal) represents the correct match. The data retrieval operation is achieved by adding the two halves together. In the pre-recorded DVD application, the poor match method is used, where Divide the reflected light into four parts, and compare the phase of each part to determine the docking status. Most CD-ROM players use three-beam hf retrieval and docking, as shown in Figure 4 below (but red book) Only the standard of single beam pp pairing is specified.) In the two beam pairing operation, the reading beam is separated into three beams: the reading beam I, one pointing one or more in front of the reading beam. The first-to-riding beam with a mark length and offset distance (about 3/4 mark width) to one side, points to one or more mark lengths behind the reading beam and is offset 1/4 to the other side The second pair of beams. Continue to individually sense the reflected light of each of the two pair of beams for the pairing in the manner described in the previous paragraph on PP pairing. Beam focusing is also achieved via a suitable feedback mechanism. Beam focusing is generally used and is well known in the industry, so it will not be described here except to explain the specific needs that may be required.

According to the Orange Book, mixing = ribbons are well known to people. The optical center is usually from the center of the ring and Wei, from the disc t center radially outward and with reference to Figure 19 (Mei Zai Erdu). The first is ri Ί ', Gu Xu 0) —The R writer optimizes its nominal writer laser power. The next one is R0M1 with 302, "Program management area (service), / (Xiao _ _)", whose universality includes winding discs at most. This ring Z 1 is information on the number of tracks performed on the disc, and its purpose is to close the disc month after burning. The next step is to selectively widen R2 and Mmm, and finally, the zone may extend to the periphery of the disc. The manufacture of hybrid discs is a multi-step process. First, a master mix with the necessary sequential tape and R tape must be created. At this time, the bandit information is recorded into the optical recording layer on one surface of a blank master plate, and the substrate of the master plate must be any suitable substrate. Polycarbonate or surface, blood / -surface, (: from Top mine) Burning 'See below. The substrate must of course be transparent to the master disc produced by the third surface burning method.

The entire mother will learn the way thief ΑΉρ timing information. Master-type hybrid discs are usually produced by two methods-methods. The two methods are photoresist ('pir') method and dye-polymerization test. There may be a method for making other masters of the age and it will be heard in the future-there will be, but this manual will focus on these two methods, of which the PR method is currently the most widely used neo-L · 〇25 method . -9-This paper size applies the Chinese National Standard (CNS) A4 Regulation (21〇χ 297 Public Love. 200419559 A7 B7 V. Description of the Invention (8) " ~-Photoresistance (,, PR〃) Burning Method Essence The above is a kind of photographic plate making process. The recording surface of the master mix disc includes-a photosensitive polymer thin tree month layer of a substantially uniform composition having almost the same exposure characteristics as the photosensitive latex of photographic film. Therefore, PR It is a purely photochemical (ie optical) optical method_5. In other words, in the PR method, it is not perfusion that exposes the photoresist by the heat in the table 21 ^; it is only the amount of incident light Decide whether sufficient exposure will occur and form the desired three-dimensional features. The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs needs to have a threshold amount of light in order to cause the beginning of the exposure on the photoresist surface. The degree and depth depend on the intensity and duration of the 10 written laser light irradiated and the optical characteristics of the photoresist material itself. Because light absorption and scattering occur in the photoresist medium, and the development process, The exposure width in the body usually decreases as its depth deepens. However, in principle, under the same duration (rotation speed), the increase in the incident intensity will lead to a deeper exposure depth in the photoresist medium. The 15-degree radial width at the exposure (especially on the surface) is determined by the written beam width. It should be understood that the beam cross-section can be regarded as an Airy disc with a radial intensity Gauss Gaussian distribution. Since PR is a purely optical process, the beginning and end of exposure are instantaneous, because the writing beam is activated and reduced for each writing pulse when the disc is rotated below the beam. 20. The data pulse (,, turn-on time) will eventually generate pits on the surface of the master hybrid disc, and the turn-off time will get the intermediate flat. Because the entire data stream is encoded, The marks and independent data are contained peacefully. During a PR burning operation in a ROM area, an EFM (or EFM Plus) coded waveform causes light to illuminate the recording surface of the rotating master disc (usually from two Polar body or gas laser) 25 The intensity of one of the focused spots is adjusted. By adjusting the CLV speed of the disc and the beam -10-This paper size applies the Chinese National Standard (CNS) A4 (210 x 297 mm) 200419559 A7 B7 V. Description of the invention (9) * The radial position relative to the center of the disc is properly synchronized, so that a flat space in the ROM band is interspersed with unexposed flat ground, and the light spot is turned on. The narrow, usually long latent image produced in the state. A continuous latent image spirally coiled on the disc is created in the R band. The width of these images in the case of CD master production is slightly smaller than about 5 The meter is still small, and in the case of mastering, it is about half because the DVD is about half the size of a CD. When the entire ROM area and R-band spiral track (or a collection of concentric tracks) have been exposed to the surface, the master mixed disc is developed like a normal photographic film. In this step, an etching solution is introduced to dissolve and remove the exposed area of the resist (or 10 is the unexposed area, depending on whether the used resist is positive or negative), and mix it in the master. A series of narrow, three-dimensional 'usually elongated tiny pits and intervening flats were created in the band of the disc, and a spiral prefabricated groove was created in the R band. In the ROM tape, the visibility of these rqm appearances on the surface of the disc (that is, the horizontal range) will be approximately the same as the effective width of the writing beam. 15 The same applies to the surface width of the discs with the pre-grooves inside. The width of each pothole and prefabricated groove below the surface is reduced. The interval between each successive pair of transition areas (transition from a pothole-flat land to the next flat-pothole transition, and vice versa) individually represents a specific data corresponding to the original EFM (or EFM Plus) signal Data range of the packet (ie pulse wave). 20 The thickness of the photosensitive data layer deposited on a thicker glass or polycarbonate substrate is usually chosen to be the same as the desired ROM pit depth. Therefore, when the photoresist is fully exposed (through its full thickness) due to a writing beam of sufficient intensity, a flat bottomed cavity is created. Its depth will be the same as the thickness of the photosensitive layer. Its cross section will show a generally trapezoidal shape, and its 25 joints from side to bottom (usually from surface to side) will be quite sharp. As the PR method is a photographic plate-making process, and -11- this paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) 200419559

Noise has a greater sensitivity. Indeed, because the PR method of disc mastering is a surname-engraving process, it usually produces a three-dimensional appearance with a rough wheel surface. This damages the accuracy, because the signal is played The amplitude is affected by surface characteristics. This problem is further explained in US Pat. No. 5,696,758 of Yanagi_hi et al. And US Pat. No. 6,212,158 of Ha. Et al. No sound how the thickness and exposure of the silk layer Greenness (and the resulting potholes or prefabricated? 1!

As mentioned earlier, the width of potholes and prefabricated grooves It is determined by the power and effective width of the burning beam. The latter is determined by the Using the wavelength of the laser and the numerical aperture (, NA〃) of the focusing member, the mosquito is known in a conventional way. Whether it is a lion or a triangle, the transverse profile of the pit may be determined by the optical characteristics of the photoresist material, the surname The engraving procedure, writing beam power, and specific focusing structure selected are controlled at least to some extent, as described in the patent literature. Finally, the length of each completed ROM cavity is mainly determined by the corresponding (or EFM Plus) data pulse. The duration of the wave determines the length of each intermediary ground. Once again, no matter what the application is, the PR method is essentially an etching process, and even if the photoresist is fully exposed, it will inevitably be in the pit.

Somehow rough. Although it has not been proven that this is a special problem for general CD-ROM master production applications, the PR method of master disc production is suitable for master hybrid hybrids that can quickly produce hybrid CDS under a low defect rate. The manufacture of CD9 did not help. This is because the PR method has four inherent characteristics: (1) it is prone to 5 appearance features with sharp edges in the transverse section, which causes molding problems that increase cycle time; (2) caused by partial exposure of the photoresist There are many noises in the reading of the shallow appearance features; ⑶ it is-a program that is difficult to control; 固有 pR made ^ the inherent roughness of pits and channels hinders accurate hybrid CD data retrieval. In addition, PR-made master discs have increased their data density to today's CD-DVD and DVD levels of approximately 4 2 billion bytes per data layer, and the data retrieval strategy must become more complex. Its coarse chaining problem will only become more troublesome. '' The dye-polymer optical data recording method is disclosed in U.S. Patent No. 5,297,129 (hereinafter referred to as, '129 patent and U.S. Patent Application Serial No. 09 / 558,071 (hereinafter referred to as, 15 cases of the parent application), each patent case is assigned to the assignee of this case and is incorporated by reference in its entirety. 70 The Intellectual Property Bureau Employee Consumer Cooperatives of the Ministry of Economic Affairs does not print the PR law, dyes The physical recording method is a heat treatment method, which is based on a physical principle that is quite different from the basic principle of finding methods. As described in Patent No. 129 and the parent application, this heat treatment method requires a fairly complicated writing strategy. 20 is because in the case of dye-polymer, when the master disc is rotating and the beam is activated to form per-pits, it only takes a small amount of time to heat the dye-polymer to its thermal threshold. This results in the resulting pothole having a tapered leading edge. On the other hand, cooling occurs almost immediately when the beam is stopped, resulting in a dull trailing edge. Therefore, it is different from a wrist that can be almost unmodified Wave is used for laser beam 25 pure optical pR method for intensity modulation.

12 10 15 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 20 25 The EFM pulse was modified to offset these thermal effects. Patent No. 129 solves this problem and proposes an effective dye-polymer master making and writing strategy, and the parent application non-exclusively identifies each equivalent. Hybrid dyeing with polymer-programming process 0) or DVD mastering includes selective punching out of the photothermally activated recording layer of the master hybrid disc, thereby creating a series of potholes and intermediary flats in the band, A pre-groove is created in the R-band. This recording layer consists of a polymer (such as nitrocellulose) and a mixture of dyes. The color of the dye is complementary to the color of the human beam (usually visit) to promote the most local heat absorption effect. _- 麟 舰 组合 _The age of dyeing is sufficient to eliminate the need for laser power of overcapitalization, and is low enough to allow the effects that may be caused by dyes remaining on the surface of the master hybrid disc (for example, from Noise readings on the final hybrid disc) are minimized. The proportion of dye in the dye-polymer mixture is usually quite low, preferably about 3 to 5%. When making the collection strong and narrow: write the beam (such as the off-beam electron beam source), the color selection of the secret (if any dye is really used in its application) will abbreviate the specific type of human beam as the basis Generally known principles. Accurate data retrieval requires accurate matchmaking. Therefore, the recording parameters used in the dye-polymer hybrid r: master: Γ operation must provide accurate three-dimensional pits =, flat structures and prefabricated channel gangways, thereby ensuring the commercially available follow-up copy and post-burning Of the mixed type of information, data retrieval. Unfortunately, because of the Redbook's specification requirements for all pre-recorded CD applications, accurate HF price measurement and accurate (push-pull) alignment or some criteria are mutually exclusive. In the Orange Book CD-R, Talk-R, and hybrids, there is a reflectance of ^ f material. The same reflectance exists-the same basic coordinated slice specifications are prepared for pp and grooves. 14-Table paper size is suitable for fiscal countries Standard (CNS) A4 specification x297 male 200419559 A7 B7 V. Description of the invention (Π) The desired HF is optimized to an effective pothole depth equal to λ / 4 (note that each pothole usually has a factor-dependent dye- This is achieved under the conditions of an arc-shaped base caused by the polymer punch-out procedure, which in turn is the wavelength of the read beam (usually a laser) in the substrate material (because the disc is usually read from the second surface). This will cause a 7Γ (180 °) phase shift in the reflected light, which effectively cancels out a small amount of incident light that does not diverge due to diffraction. In contrast, almost 100% of the incident light is reflected from a substantially flat, flat ground. Then, under the condition of λ / 4 effective pothole depth, it can be seen that the reflected light detected in each pothole / flat ground transition will change very rapidly, which will help the accurate detection of potholes and land lengths. One test is exactly 10 tests. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In contrast, PP detection usually measures the amount of light diffracting from a pothole at an angle relative to the vertical direction. It is normalized via known or observed disc surface reflectances to provide comparative values under specific background conditions. Therefore, in the application of Cj), only the amplitude comparison of the light detected from the PP debt measurement on either side of the longitudinal service axis (whether it is in a pothole or flat area) is detected. When the pp detection source receives more reflected light on one side than the other, the pp servo moves the reading beam radially in the opposite direction until it detects that the two halves representing the correct pairing are equal. A Λ / 8 effective channel depth that produces a 7Γ / 2 phase shift optimizes the pp detection, not the HIM chastity test; the channel depth after a quarter and the corresponding 10,000 phase shift. As mentioned in the previous 20, one is similar; the 1 / 8-and / 4 dichotomy exists between PP and unrecorded channel reflectance in the CD-R and R applications, and other optical recording uses hybrid CDs. ) There is a very similar dichotomy. -A recently approved European patent E " 嶋 321 25 -15-, 'S—) to some extent improve the PP side of the optical data disc (obviously-dye-polymer burning) and hope not to It will sacrifice the Aberdeen paper size to apply the Chinese National Standard (CNS) A4 regulations (210 x 297 public publication 200419559 A7 B7) V. Description of the problem (14). The proposed solution is to write the pulse The intensity of the writing beam between the two is maintained at a level just above the thermal threshold of the mobile medium. This will create a shallow and narrow channel in the flat area connecting successive pits. That is, pothole / flat ground transition) In the state of detection with minimal negative effects, the quality of the PP signal between potholes can be improved. To some extent, this method seems to satisfy the pp most. The "optimization criterion" can be used to make a flat channel with an effective depth of approximately λ / 8 (in the case of a hybrid disc, the effective phase depth will be approximately / 8). However, because this is done by writing Beam intensity weakens to near the thermal threshold, and the resulting flat channel must be comparable 10 is narrow. But this actually hurts the PP detection, because the other special purpose of the pp / HF dichotomy is that the best PP detection is a channel with a width larger than the channel that will optimize Xing detection Realized. In addition, Schoofs did not explicitly solve the problem of HF detection. In fact, the logical extension of what Schoofs described will be to further increase the beam intensity between the pits and widen the channel in hope of better alignment. However, it will actually be better. The deepening of the channel will damage the detection, and will also damage the HF detection because it makes it harder to detect the pit / flat transition area, which will negatively offset any pp improvement provided. In the case of hybrid disc manufacturing, the Ministry of Intellectual Property Bureau's Consumer Cooperative printed very similar problems that follow the methods described by Nakagawa, Yanagimachi, and Ha, which will be briefly explained below. 20 What method is used and what format (CD -ROM, hybrid 0), etc.) Creating a master disc (such as PR method or heating method, such as dye-polymer method) is only the first step of the disc manufacturing process. The final disc is the target.

According to the Red Book Regulations, the CD distance (IP ") is between 1.5 micrometers and L? Micrometers' nominal value is 1.6. Micron. EFM-coded CD pits have a nominal length of 0.3 micrometers per τ measured from half depth (from which all widths and lengths are traditionally measured), where the pit length spatially represents a round of nT instantaneous duration Into the data pulse running length. The width of a CD pit (, 'pw〃) (which was measured again at half depth, as shown in Figure 18) and the spot diameter of the writing beam that created the pit Both are about 0.5 micron, that is, about TP / 3. On the other hand, the read beam is about twice this width, or about 丨 micron wide. Due to the various laser wavelengths used in CD burning operations The numerical aperture of the objective lens that focuses the beam must be selected to be generated regardless of the spine—the same straight beam beam level, so that there will be pits of complementary width regardless of the position, thereby ensuring that the resulting pits can be uniformly used.

Double-sided (or double-layer) discs can be produced by using two molds (with two master layers on each side). Each mold is made from an independent master disc recorded in the aforementioned manner.

Description of the invention (17) " ------------- A spin-coating-heat-activated recording layer on each net copy hybrid disc; a thin layer of metal reflection is usually placed on this layer; Apply a protective layer to say 'handed recording layer' tends to fill the bandit data pits (especially shorter running length: those such as 3T to 5T, see below for details) and the flat part of the intermediary, and the optical obtained from the r π prefabricated groove The depth of the recording layer above the Likeng cave and the R-belt prefabricated groove (which will be burned with CD-R data pits later) depends on many factors, such as the viscosity of the dry layer, drying conditions, rotation speed, and pit Horizontal shapes of holes and prefabricated grooves. The final hybrid disc and the post-burning hybrid disc must fully comply with the Orange Book specifications as a whole, and their bands must also meet the Red Book specifications included in the Orange 10 Book specifications. Although the conventional arts have put forward very confident claims, their disclosures, whether individually or collectively, do not seem to be able to propose a method of providing a range of parameters that can be selectively adjusted. The maximum value is maximized and thereby contributes to the overall flexibility necessary to reliably manufacture discs meeting Red Book and Orange Book size 15 in a high-speed manufacturing environment. The Nakagawa Hybrid Disc Patent (U.S. Patent No. 5,204, 852) printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs is based on the ROM data pit and the photoresist burning with R prefabricated grooves (No. 5 paragraphs, lines 3-20), and proposed to expose the photoresist in the r0m region at a level different from the R-band region. It proposes two basic embodiments: one embodiment presents a prefabricated groove with a triangular transverse section 20, and the other embodiment presents a rectangular transverse section. The prefabricated grooves of these two embodiments are shallower than the ROM data pit because the photoresist is not fully exposed while the prefabricated grooves are created. As mentioned above, this partial exposure of the photoresist will result in a triangular cross-section prefabricated groove of the first Nakagawa embodiment. However, Nakagawa failed to see how to produce prefabricated grooves with triangular cross-sections such as 25H. In fact, it is necessary to achieve -19 by its disclosed method. This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210x297 mm). 200419559 V. Description of the invention (18. It is also expected that this purpose can be turned into _._ 在Some light scattering may occur in the light, and the exposed cross-section will tend to narrow down from the surface of the disc to produce the trapezoidal wheel that is generally observed. It is very good because at least $ know about the two E-rectangular section preview 5 = Difficulty, Naka Za proposed-third embodiment (paragraph 11 line 16 to paragraph 36 line) 'One of the first beams exposes the photoresist in a (hopeful) cross section The pre-groove is then partially exposed by a second beam in order to reduce the effective depth of some pre-grooves. I may realize that this type of photoresist double exposure method is at most ^^ very difficult to control 1〇 For example, it has not been suggested how this can be achieved. 15 > In addition, even Nakagawa or those skilled in the practice of what he has mentioned have really created (but very unlikely) dirty potholes with rectangular cross sections and Conversely, pre-groove master discs, these masters are to be copied It is also almost impossible, simply because the net copy hybrid disc will be strongly adhered to the production mold, which will present hundreds of thousands of appearance features with vertical sides instead of generally seen in pR production masters. The trapezoidal cross-section features the hypotenuse. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 20 25 In Nakagawa's net copy hybrid discs, the depth of the thermally activated recording layer applied to the prefabricated groove of the R tape must be greater than / Zhu Du above the pits in the recorded band. This is to ensure that after the spin-coated recording layer spread over the entire disc has been covered, the resulting pits in the R band are selectively burned. Will have the same effective optical depth as the pits that already exist in the ROM segment. Therefore, Nakagawa suggests that when the thermally activated recording layer has been spin-coated on a net copy hybrid disc, the cross-section of the corresponding feature will be guaranteed Correct corresponding depth. This would be very unlikely if the prefabricated tank had a triangular cross section. As mentioned earlier, the way Nakagawa created the prefabricated tank (reducing the exposure of the photoresist in these areas) This method will make this paper very -20- scale applicable Chinese National Standard (CNS) A4 size (210 χ 297 mm) Ministry of Economic Affairs Intellectual Property Office employees consumer cooperatives printed 200 419 559

Do not. It is not easy to produce the desired rectangular cross-section prefabricated grooves, and even if such masters are produced, it is very impossible to make replicas conforming to Orange Book specifications. In other words, the simple approach proposed by Nakagawa to create the desired difference within the thickness of the corresponding ship's thorny charm recording layer is unlikely to be successful. 5 Unfortunately, if the latest news is based on Makagawa ’s content, it will not only seriously damage the opposing side (_ is a hybrid disc R-band), but the HF test of the R-band i may also be more difficult. Because these pits are roughly pressed into the narrow prefabricated grooves and then radially outward, bulging. Therefore, the most likely result of following the content is a hybrid that does not meet the 10 specifications of either Orange Book or Red Book. Non-compliant hybrid discs are useless.

Yanagimachi (U.S. Patent No. 5,696,758) mentions another photoresist 1 master 1 method, which essentially says that you want to follow the touch and listen to the method. By making the exposure of the photoresist in the R band less than that in the R band as described by Nakagawa, and further using a method in which the exposure level in the ROM ground is lower than the I5 level of the job hole exposure, Yanagifflachi The channels created in the simple area of the net-replicated hybrid disc are narrower and shallower than where they are, connected, and potted. When the thermally activated recording layer is subsequently spin-coated on a net copy hybrid disc to make the final hybrid disc, there will be fewer ROM slots left. This is in addition to the problems in the Nakagawa case. R-pits and channels are not easy to allow themselves to receive HF or PP detection. In addition, 20 Yanagimachi does not mention how to independently control the width and depth of ROM channels, ROM potholes, and R-grooves. Those skilled in the art will know that if -PR is narrowed by reducing the laser power of a single beam, its depth will be correspondingly reduced. Yanagimachi, which explicitly mentioned the use of a single beam (paragraph 6, lines 23-32), did not provide any assistance in this regard. Therefore, for those skilled in the art 25 to produce hybrid discs that may meet the Orange Book and Red Book regulations, -21- ^ This paper size applies the Chinese National Standard (CNS) A4 Regulation (210 X 297 mm) )

What Yanagimachi said was less instructive than Nakagawa, even if it made sense.

Ha (US Patent No. 6,212,158) differs from Yanagimachi mainly in certain parameter values. Specifically, Yanagimachi specifies a ROM pit depth between 5 250 nm and 350 μm and a ROM channel depth between 30 nm and 170 nm, while Ha specifies a depth greater than 170 nm. Channel depth in micrometers. Indeed, the Ha case in paragraphs 36-43 of paragraph 1 points out the difficulty of the Yanagimachi case to create acceptable hybrid discs that incorporate the recent tremor 'depth modulation (r0m) channel. Therefore, Ha uses a very similar concept of 10 to modify the Yanagimachi case with different parameter values, and the scope of Ha's patent application is essentially written around with the Yanagimachi case as the core. ”But Ha for the first two cases Nothing has been added to promote the manufacture of hybrid discs. To the extent that the applicant is aware of the know-how, there is no published content15 (whether alone or in any reasonable combination) that will allow him to master the skill Of reliable, repeatable, and efficient manufacturing of hybrid discs that comply with Orange and Red Book regulations. This may or may not be because all public literature known to the applicant relies on hybrid discs The photoresistive method of film master production, and the printing method of the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, as mentioned above, is not impossible, and it is very difficult to use it to produce a hybrid that can be remanufactured to meet the necessary specifications. The master of the disc. For whatever reason, it seems that it is impossible to commercialize a hybrid disc that meets the specifications based on conventional techniques. Therefore, a method is needed. The pits, flats, and pre-groove geometries in the method, a device, and the master hybrid discs obtained thereby enable efficient, rapid, and reliable manufacture of replica hybrid discs that meet all applicable manufacturing specifications. 25 -22- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 public love) 200419559 A7 B7 Description of invention (21 10 15 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 20 25 Summary of the invention The ultimate goal is to provide master hybrid CD and DV]) discs and other formats (such as CD-RW) master hybrid discs (including higher data density formats), so that those skilled in the art can Reliable manufacturing of hybrid discs meeting all applicable specifications in a high-speed commercial manufacturing environment. Therefore, one object of the present invention is to propose an apparatus and method for efficiently producing such master hybrid discs. Another aspect of the present invention One object is to propose a method for producing such master-type hybrid discs by heating the master-making process. In particular, one object of the present invention is to propose a master-type hybrid disc The ROM pit and flat structure and the R-belt prefabricated groove structure are convenient for molding to effectively produce net-replicated hybrid discs. When these net-replicated hybrid discs are conventionally transformed into final blends in a commercial manufacturing environment Discs will comply with applicable industry specifications. ^ Another goal of Ben & Schömmer is to develop improved masters of CD-RW hybrid discs and MO discs, and to provide improved hybrid discs made therefrom. According to the present invention, in the most basic point of view, the master-type hybrid ROM ROM is burned in the lateral range (the definition of which is described below) which is wider and shallower than these ROM holes. ROM slots, and the ROMs that usually form the parts of the ROM slots are interspersed between successive ROM holes. In some embodiments, the width of the ROM pits can be as high as 11% of the width of the grooves. These widths are measured at half depths, respectively. In some embodiments, the R⑽ grooves and R tape grooves are provided in the master hybrid disc, and each groove is wider than the ROM hole. The ROM grooves and R tape grooves usually constitute A continuous spiral channel extending through the ROM and R regions. According to a preferred embodiment of the present invention, a dual-beam burning device is manufactured. -23- Thread book size is applicable to Chinese National Standard (CNS) A4 specification (210 x297 public love) 200419559 A7 B7 V. Description of the invention (22) 10 15 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 20 25 Master hybrid discs. The intensity of the individual beams and their diameters on the surface of the master hybrid disc can be selected individually, whereby the structure of the channels and pits in the master can be selected and optimized to produce a final mix that meets the specifications at the end Discs. In the preferred embodiment, when the master disc is rotating, the beam of the ROM slot will lead the beam of the ROM pit. In other embodiments, the two beams may coincide, or the slotted beam may lag behind the pit-forming beam. In most embodiments, the present invention utilizes a heated mastering process. This ensures that the surface of the pits and channels is smooth and inclined, which is more conducive to efficient, high-speed net copy molding operations. In some embodiments, it is easy to reduce or reduce the berm naturally formed on the radial boundary of the pits and channels in the master hybrid disc due to the natural punch-out process inherent in the heating master making operation. It even disappeared. This also helps to produce a final hybrid disc that meets all applicable manufacturing specifications. In a preferred embodiment, this is done by creating a cavity with a beam and at the same time using a second beam with a beam width greater than the first beam and a lower intensity at the surface to generate or otherwise The resulting slope is minimized or even disappeared. In some embodiments, the second beam is activated during the complete creation of a ROM tape, and the stronger and narrower first beam is activated in response to data-based beam modulation or The removal resulted in a series of ROM potholes and flat ground, of which the flat land was a continuation of the channel where the narrower potholes were located. In some embodiments, a single dithering beam is used, wherein the instantaneous beam intensity and its dithering pattern are controlled such that, in effect, this dithering beam is the same as a double beam. Indeed, it is necessary to understand that the single beam of the f-knowledge technique refers to a single beam that does not tremble, because the tremor writes that the human beam is very _ 未 # seen in the cognition technique.

Invention Description (23) An example of the production of a CD-R / D chest master will be briefly mentioned at the end of a book. Brother Xiongming The following will teach some examples. The implementations are shown in the drawings. The other two embodiments are described below. For convenience, the following description is expected to start from the CD hybrid type produced by the method of making a master material, but it does not mean that the present invention is pseudo-limited to this format or related aspects. In particular, it is to be understood that although the ^ material-polymer method is often mentioned, 'the present invention can use any suitable heat treatment procedure in contrast to, for example, the conventional pR procedure or other Zhaoxiang plate-making procedures ...' In the description, in this specification, any process that the "heat treatment procedure (age-qing ess) big red and green can be used to cause controlled thermally induced micro changes in a medium can be used to transfer money to silk. In this procedure, an optical (e.g., laser) or quasi-optical (e.g., ion or electron) beam forms a three-dimensional feature in or on a substantially homogeneous composition layer due to the regional heat generated by the beam. This is in contrast to -pure optical methods (such as the pR method) because the amount of light rather than the heat generated by the beam leads to feature formation in the end. The following description sequence is as follows: First, it will thoroughly explain the improved method of using the master material-gathering to sequentially burn the master mixed disc. It will then confirm and resolve. = Piece: Various structures of the capture feature, focusing on ensuring the final hybrid type "and post-burning hybrid discs will reliably meet the Orange Book specifications and Huili ^ will reliably meet the Naren's Red Book Listening Dragon A good system.

Invention description (24 for short explanation, because it is well known to make CDs from recorded masters, there is no obvious deviation from the conventional CD copying method in the net copy hybrid disc manufacturing process. However, since "& coating and related procedures are well known and dye manufacturers often refer to procedures such as = (because of the burning speed certification), this section will be used to convert 〒 copy hybrid discs into The final steps of the final hybrid disc that will meet the fine specifications are briefly considered. Finally, a brief summary of these contents is summarized in different formats today and in the future. It should be understood that due to the master hybrid disc and the Net copy The size and relative structure of the corresponding features of the duplicate hybrid discs are almost the same. Many of the following descriptions of the master hybrid discs are also applicable to net replicas. The final surface has multiple layers applied to it. Hybrid discs will have features that may differ in shape or size from the master's counterpart, but the characteristics of these final hybrid discs will be read correctly during playback. The same master and duplicate final hybrid discs The concept of film pairing is almost the same, and the explanation of this issue is also applicable to them. ^ The beginning of the situation is to discuss the burning of beautiful data pits in the master hybrid disc. Note that the drawings are not drawn to scale, and they are only used as illustrations of the features and concepts indicated. Spear 2 is a schematic diagram of the device used to create a master hybrid disc, mainly used The origin is its overall structure. This device is particularly related to the extra components used in the production of hybrid disc masters, which are illustrated in Figure 13-17t, and will be mentioned here to explain. ~ Now refer to Figures 1 and 129 Patent The hybrid disc 1 on the recording surface data pit and the intermediary flat ground is rotated by a spindle motor 3, which is controlled by -speed control. A gas laser 7 forms a writing beam 9 with a specific wavelength. Paper Standards (CNS) A4 Specification ⑽χ 297 Publication: -26-200419559 Α7 Β7 V. Description of the invention (25 In this example, a gas laser is used to write the beam through an external light modulation Cry, this modulator changes the intensity of the write beam according to a drive signal from the waveform shaping circuit 31 on line 10. As mentioned above, the optical modulator u may include, for example, an AOM or a comparator. Fast response EOM (Photoelectric Modulator). 5 The modulated beam 13 is directed at the master disc 1 and focused into a light spot 15 on the active surface 43 via appropriate optics, as previously described. These optics preferably include an objective lens 17 and a beam-expanding (i.e., condenser) lens 19 that expands the modulated beam 13 to fill the aperture of the objective lens 17. The numerical aperture (,, //) of the objective lens is selected so that the diameter of this spot is approximately 0.5 micrometers (in case of CD burning case 10), which is equivalent to the wavelength of a typical laser beam used today. These lenses are mounted on the / moon wood 21 to make radial movements from the center of the disc 1 to the radial spot 15 in the valley. This is achieved with a general translation drive system 23, and those skilled in the art will know the details of the system. Alternative 'Although Figs. 1 and 2 show that the radial movement of the spot 15 is controlled by a 15 translation system 23 to move it, and the rotation axis of the master hybrid disc is kept fixed, the reverse is also feasible. In other words, the position of the carriage may be fixed. In this case, the disc device will move, causing the rotation axis of the disc to be synchronized with the timing parameters written in% order. In either case, assuming correct registration, the beam printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs will continue to move relative to the center of rotation of the disc to produce the desired narrow spiral 20 data registration. In the embodiment of Xingfujia, the driving signal of the optical modulator 11 is formed by the waveform shaping circuit 31, as described in the '129 patent. A synthetic sequence driving pulse waves' The tail region of each pulse wave shows a gentle amplitude decay. This mild recession 25 may include, for example, a linear slope, an exponential decay, and a series of steps. -27- This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X 297 public love) 200419559 V. Description of the invention (26) 10 15 20 25 The shape gradually declines in amplitude or a double step (where the middle step may be at the beginning of the tail region, half of the amplitude of the switch). Other mildly decaying distributions can also be used in the tail region. It is to be understood that the purpose of any mildly decaying region is to reduce the amount of heat generated in the reactive dye-polymer layer 43 at the trailing end of the formed pothole. The amplitude of the driving pulse wave shows a gentler decrease in the heat generation caused by a single sharp drop from the base to the write level to, and off to the base. For the sake of convenience, any gentle tail edge eclectic distribution that contributes to this desired result will be interchangeably referred to in this specification as' ramp ^ ° Any such tail edge slope (this term is in the previous text) Broadly defined) effect in the '129 patent patent bribe caused the tail end of 60% of the pit into a cone. The leading end of these potholes will be tapered because it takes a short time after the leading edge of the Thunder-wave (the light spot 15 starts to act on the heterolayer 43) before the fast-moving medium feels all the heat accumulation. The leading end taper can be more or less purified by increasing the laser power at the edge of the pulse leader as is common, but it is essentially impossible to completely eliminate it. Therefore, after the start of the corresponding drive pulse, it will be formed into a gradual edge on the edge of the pit: then the amplitude and slow decay at the trailing edge of the laser pulse will gradually narrow in the pit, reflecting the _ . This selective cone: the tail = and the 4th end creates a geometrical loss i, which facilitates the HF detection of pothole-level crossings, as disclosed in the '129 patent. = The present invention does not rely on the content of the principle described in Patent No. 129, and it does not include the principle of Patent No. 129.

The master disc 1 will generally include a substrate 4 and coated on An active (dye-polymer) layer 43 on the substrate. A transparent member 45 can be sandwiched between the / tongue 11 layer and the objective lens 17 to shout dust and other impurities on the active surface. Another option The active layer may be formed on the inner surface of the transparent member, or any other suitable structure of the elements in the master hybrid disc 1 may be selected according to specific circumstances and preferences, which may be as shown in FIG. One surface burning or the second surface burning is featured. Figure 2 is roughly the same as Figure 1, except that Figure 2 depicts the structure that may be used under the condition that a diode laser 7 is used. Due to the diode laser It can respond to its drive signal input almost instantaneously. In this application, no external optical modulator is required. The output of the waveform shaping circuit 31 'can be connected to the direct drive signal of the laser 7 through the line 10. Variable beam 13, from laser 7, directly A. In the embodiment shown in FIG. 1, is depicted a single waveform shaping circuit 31. When 25

Although these data pits are usually elongated as shown in Figure 3, they may appear today or in the future.

Therefore, what is disclosed in the present invention (or '129 patent) is not limited to the length-branches of data pits or other data marks of thieves. Figure 3 depicts a single beam (Pp) Matching, referring to the master hybrid disc, the final hybrid disc, or a CD writing device that burns the latter. A single reading beam 60 is used as the HF (for hybrid discs). Case) and PP lying light source. The reflection of this beam is appropriately transmitted to a conventional picker (not shown), where the reflected beam is separated into two equal semi-circular components, which are composed of _ The divider is parallel to the beam direction. As mentioned earlier, the HF side includes the observation of the instantaneous amplitude of the light reflected vertically from the disc surface—in a way that the outputs of the two detector components are summed up and Pothole-level transitions are aligned when the amount of light detected reaches a predetermined value. Too much light indicates that the read beam is above a flat area, and too little light indicates that the beam is in the -pit ± square. The pp side includes comparing the light received by the two side device components and diffracted from the surface of the disc in such a way that the output of the called sensor component is subtracted from the output of the other component—servo feedback will read the beam Move radially until the two halves produce the same reading. Figure 3 shows that the diameter of the read beam 60 is approximately twice the width of the cavity 50, as is common in these cases. Figure 4 depicts a three-beam docking system commonly used in CD players, where three beams 61, 62, 63 are used. The central beam 61 is simply a reading beam, which is equivalent to the reading beam 60 of the single-beam pairing system shown in FIG. 3. The front beam 62 is shifted by about a quarter of a distance (TP) toward one side of the opposing axis of the opposing device, and the rear beam 63 is shifted by the same amount toward the other side. As mentioned earlier, τρ (radial axis-to-axis distance between adjacent data sections or sections) is approximately three times the pit width, as shown in the figure. Unlike the single beam pairing, the reflection of the central beam 61 is not separated and is only used for HF detection (also used for focusing in some systems).

The radial adjustment of Shida is continued until the alignment axis is aligned with the longitudinal axis 64 of the pothole tunnel. Since the booklets and counter-sides in single-beam and triple-beam configurations are well known in the art, there is no need to explain more about their corresponding devices here. 0 5 In the following description of Figures 5 to 12, The structure of various appearance features in the master hybrid disc will be mentioned, as shown in the figure. Since the characteristics of the net copy hybrid discs are essentially the same as the corresponding characteristics of the master hybrid discs from which these net replicas are reproduced, it should be understood that the features of the master hybrid media mentioned in these drawings The construction of the% M is also applicable to the corresponding features in the net copy hybrid disc. 10 = Samples are reasonable. Due to Wei Jia ’s special choice of net copy mixture, it is left to the practitioners to choose (probably according to the manufacturer's specifications and instructions for use). It is impossible to draw more than Figure 23 and The corresponding structure in the final hybrid disc other than the approximate one shown in 24. As only the final hybrid disc and the post-burning σ-type disc must meet the specifications of the Orange Book and the Red Book included in it, like the 15, it is necessary to understand that the materials, devices and Based on the printing of the employee's consumer cooperative of the Intellectual Property Bureau of the Ministry of Program Economy, the mastering process and the process can be optimized in the manner described below to achieve the results promoted by the present invention. In other words, the present invention proposes an improved mastering technique and clothing design. ^ If this technique is used locally, it will lead to the ultimate advantage that the final hybrid disc will far exceed the level that can be achieved in the past. Secret optimization. 20. FIG. 5 illustrates a cross-sectional structure of a ROM pit 50 generated in a master-type hybrid disc manufactured according to the dye-polymer method described above. Note that the slopes 70a, 70b protrude above the surface 68 of the disc. As mentioned earlier, this is a natural consequence of the plasticizing part of the rush process of these potholes. Note that the existence of these slopes has changed i: the effective phase depth of i holes. Based on this structure, the optimization of the production parameters of the hybrid disc master 25 can provide effective HF detection with a reasonable registration signal. -32- This paper size applies to China National Standard (CNS) A4 specifications ( 210 X 297 public love)

---------- I 200419559 A7 B7 V. The final hybrid disc of invention description (31). However, due to the dichotomy between PP detection and HF detection requirements, the intensity of the burning beam must be set so that the effective pothole phase depth in the final hybrid disc is approximately 3 λ / 16. However, this neither optimizes HF detection (requires λ / 4 effective phase depth) nor optimizes counterpoint (requires λ / 8 effective phase 5 depth). FIG. 6 illustrates a modified structure of ROM pits and intermediary flat land in a master hybrid disc obtained by a preferred embodiment of the present invention. It can be seen from the figure that there is a wide and shallow channel 75 that extends along the longitudinal axis of the pit and flat sequence, and the financial pit sequence is within it. The width of this channel is larger than the ROM pit. The narrow channel between the wider 10 channel of the present invention and the pothole proposed by Schoofs and the aforementioned

Nakagawa'Yanagimachi and Ha reference cases proposed similar narrow channels connecting subsequent potholes are significantly different. The intended purpose of the narrow channels of these references seems to be to assist in counterpointing, but taking into account the resulting dimensions and following these references The other contents of the case will actually fail to achieve this purpose to a meaningful extent. The advantage of the flexibility of making the 15 ROM potholes, ROM channels, and R prefabricated masters provided by the present invention is to obtain a high-quality final hybrid disc under optimized conditions of the process, as described in detail below. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The latter became clear when my body recognized that a wide channel created by a single beam must be a deep channel. Although the increased width may promote better PP performance, the increased depth actually hinders this. For example, the Ha reference case proposes the creation of these deeper 7G nanometer) prefabricated tanks, and these prefabricated tanks will indeed provide a significant improvement on the PP side and improve the counteraction. But Ha's way of providing these ς deep prefabricated troughs actually sacrificed the width of these troughs and M potholes. : Coordination fails to provide holistic benefits. People 25 Although the optional size, wider and shallower _ Slots Meeting -33- provided by the present invention, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (21 × χ297 mm). 5. Description of the invention (32 ) It is helpful for enforcement (at least it is much more useful to provide an enlarged R-belt prefabrication). Its primary function is the high-speed recording of this technical level = instructions for use. These manufacturer's instructions for use are often ... manufacturer = ::: === Specifications and use of certain dyes can be obtained on request. The burning speed of the furnace has continued to accelerate, and it will continue to use more advanced dyes, especially for higher speeds. These know-how have not proposed how to provide good PP and HF maintained in the calendar at this time (usually designated by the manufacturer of such high-speed dyes) and both the τ mouth and the recorded R tape. == In principle, it relies on single-write coffee ^ 15: ..., and 'the present invention proposes to make the channel width and channel of the channel through two independently controllable beams or -vibrations''. In-depth independent control to provide the flexibility needed to meet the needs of the user: there are no requirements. In fact, the invention allows independent control and optimization of the lateral configuration of all features. It should also be understood that because the key embodiment of the present invention uses a dye-polymer hybrid disc master to make 'to create any desired depth in the master disc, printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs20 ROM channels and R tape prefabricated slots are not difficult. This is because the mechanics of this operation, as mentioned earlier, tend to produce smooth contour beveled recesses without surface roughness in the master hybrid disc, and only need to adjust the writing laser intensity appropriately. These recesses can easily be made in the master disc to any desired depth. This means that the master hybrid disc produced according to the present invention will be far more characteristic than the rough side PR proposed by the conventional art (such as the rectangular cross-section feature that Nakagawa hopes to create by a method that is not easy to understand). Easy to copy with general molding procedures. .34- This paper size applies to Chinese National Standard (CNS) A4 (210 X 297 mm) 2ί) 0419559 Α7 Β7

In addition to raising _ pit hole HF this improved PP copper without sacrificing _, 'way), by The reduction in the amount of high-yield material on the slope ”_ attached to the shallower crack II shown in the obtained film mold: li / v and helps to refer to the master mixed disc reference An important advantage. Lunar New Year's Day 7 ^ 175 ^ 75, big rise. But these have only a small impact on the detection of ρρ or Xing. T 'channel 75 itself in Figure 6 can Extending performance in flat areas, and finally providing a corresponding feature with an effective depth of λ / 8 in the final hybrid disc, by providing a wide and flat bottom 77 of a uniform depth channel over its entire width (as shown in the figure) The method shown in Figure 8) promotes the counteraction between potholes. This solves the problem that Sch〇〇fs only deals with a part (and is ignored by both A'agimachi and Ha), the flat area proposed by Sch00fs Slot transport (by reducing the write intensity between pits to create a bar in mobile media that just exceeds the threshold Caused by the method) is too narrow for optimizing the PP 彳 measurement, and in the case of the logic 11 extension, the channel between the pits is widened (and correspondingly deepened) due to a lower limit write intensity reduction. It will suppress the HF detection of the pit / flat ground transition. At least as far as the point is concerned, the present invention can independently control the channel width and depth with a monthly b-force δ. It can have a large channel volume without a large depth. This helps to burn faster on the R tape of the resulting hybrid disc due to the use of high-speed recording dyes of today's technological level. The almost pit-free pit 50 (shown in Figure 9) can be borrowed By adjusting the parameters, the width of the grooves in the master mixed disc is slightly increased together with the ROM 36 formed in the grooves. This paper size applies the Chinese National Standard (CNS) A4 Regulation (21〇297 公 幻 200419559).

The wide series of potholes should be made with slightly increased material. This bell number includes the beam intensity and diameter, which can be adjusted individually or jointly to achieve the following results. Appropriate selection of the channel width can cause a slope formed in the new channel of the master mixed disc-the side slope and the downward slope of the adjacent side channel 5 slope which has formed a hybrid to the adjacent channel partially overlap . In other words, two adjacent slopes merge to form a flat-topped area between adjacent channels. The sequence is repeated as more radially adjacent channels are created to obtain the Hiragaki region between all radially adjacent channels. The proper selection of the width of the ROM pits in the channels of the master hybrid disc causes the slopes of the pits formed in the new channels to be minimized or eliminated in a similar manner. If the 10 parameter is adjusted so that the potholes are only slightly narrower than the channels in which they are to be created, the slope formed on either side of the new pothole will coincide with the downward slope of the channel. This eliminates these pothole slopes in the master hybrid disc and finally in the hybrid disc itself. -The resulting feature essentially becomes a superposition of the features of the channel and the pits formed therein. Therefore, in fact, the channel caused by the two adjustments in the hybrid disc mastering process becomes a pothole, which is only wider and has no slope at this time. This result has been confirmed by repeated experiments and can be optimized by fine-tuning the production parameters of the hybrid disc master. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Fig. 9 shows another embodiment of the present invention. As mentioned earlier, in this embodiment of the master hybrid 20-disc embodiment, there are no ROM channels at all except for the flat area, and the resulting ROM pit 50 is substantially free of slopes and has a shallow slope on either side . This helps pp matchups in end-of-life hybrid discs without compromising HF detection. Measurements are improved because the shallower side bevels tend to reflect a larger portion of the incident light reflection away from the vertical direction. HF detection was not sacrificed at all, because the effective pothole depth 25 was maintained at the traditional 3 λ / 16. The net effect is an overall improvement in the figure of merit. This is the paper size. This paper size applies the Chinese National Standard (CNS) A4 specification (210x297 mm). 200419559

Just as the independent control of the two writing beams (or a single trembling beam) facilitates the precise control of the lateral structure of the pits and channels, the two independently controlled beams or a single trembling beam make a difference It is permissible to create prefabricated grooves in the R tape of the master hybrid disc in any desired lateral configuration and grip. 10 Therefore, the figure of merit in CD hybrid disc mastering applications can be improved by the present invention even without the PP booster channel attached. In addition, this no-slot, no-slope profile (as shown in Figure 9) is almost ideal for R-belt prefabricated grooves, while the embodiment shown in Figure 7 may not be so desirable for this particular application. The operation of burning R tape prefabricated grooves simply requires that each of the written laser beams has a fixed intensity ^ 15 instead of a data signal modulation of any beam intensity. However, an important feature of the present invention is that the mode of driving the writing laser to burn out each feature can be selected in a conventional manner to match the specific sequence of the β0M and R bands to be burned and the special characteristics of the specified properties. Claim. In particular, since the dual-beam dye-polymer hybrid disc mastering method is used in the preferred embodiment, the cutting from one mode to the other 20 is more convenient than the conventional single-beam PR Mastering is much simpler because there aren't most problems inherent to the pR method. There are many methods and corresponding devices that can be used to implement the embodiments of the present invention. The first thing to mention is the formation of the channel. It should be understood that an R-band prefabricated slot is simply a selective-size channel burned into the R-band, as described below. '5 For example, ROM channel 75 can be separated by writing beams 13, 13, into -38- 200419559 A7.

The method of irradiating the two beams on the active surface 1 of the master hybrid disc 1 during the rotation is performed along the entire path of the ROM pit and the flat land. Another option, channel writing = beam: only in the flat period (that is, from the end of the decay of the tail region of the human pulse to the hole writing to the beginning of the leading edge before the next hole writing into the pulse wave) start up. 5 ^ When necessary, the channel writing pulse can be selectively activated and released at any time and there is any continuation time in the pit writing process, which is specified according to the situation and preferences. Unless the slot-completing beam is maintained in the on-state during the entire process of writing a hole (or part of a hole), some components must be provided to make the channel write beam and hole write The incident beams start in concert. As shown in Figure 13-15, as will be explained in the following paragraph 10, the optical modulator signal 10 or laser drive signal 10 can be used to provide an output to control the channel to write in the beam path of the person—light modulation. The method of changing !! is easily achieved, and the start of the two beams is synchronized with a suitable conventional circuit. Printed on Figure 10 by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the situation in the master hybrid disc, in which the main ROM writing beam 102 overlaps with the ROM channel writing beam 103, making the data symbol and The channel I5 containing these marks is created at the same time. In the tangential cross-sectional view shown in Fig. 10, a series of pits 50a, b, c and intermediary flats 65a, b are formed in the photoactive layer 112 supported by the substrate 41 of the disc j. In this case, the pit is completely within the forming channel 75, that is, the upper surface of the pit is within the channel and below the upper surface of the channel H4 (unburned surface of the disc). In the embodiment shown in FIG. 10, the flat ground portions 65a, b of the data 20 are also contained in the channel. In the embodiment shown in Fig. 10, the channel writing beam is in the ON state throughout the entire programming process. It is mentioned again that the channel writing beam can be selectively activated only for the period between the formation of successive pits, thereby forming only a slotted flat area 65 along the data execution. This has no effect on potholes' HF or matchups, but the matchups between the 25 potholes (that is, in the Ping area) were changed for the reasons mentioned earlier. -39------------- This paper size applies to China National Standard (CNS) A4 (210 x 297 mm) 200419559 A7 B7 V. Description of the invention (38) Alternative embodiments may involve the use of Channels are selectively formed in a manner that provides corresponding controlled inputs to the components by which the channel write beam is generated, as described below. 11 differs from FIG. 10 only in that the channel writing beam 103 in FIG. 11 leads the main writing beam 102. The structure shown in Fig. 11 currently seems to provide the best results for the production of a hybrid disc master according to the present invention. In all other respects, this embodiment is similar to that shown in Fig. 10, and all the discussion of Fig. 10 applies equally to Fig. 11. Figure 12 depicts the situation where the main writing beam is ahead of the channel writing beam. It can be seen from the figure that the formation of potholes preceded the formation of the channel where the potholes were last. The effect formed after the 10th slot is to consistently expel more material from the formed pothole without significantly changing its structure. This method is like pressing the formed pothole down into the newly formed channel while maintaining its corresponding structure. The Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs printed all the discussions on Figures 10 and 11 (except that the structure shown in Figure n seems to produce better hybrid disc results for the time being) is also applicable to Figure 12, and should be 15 Learned that in this paragraph and each subsequent paragraph, the same method can be used to produce a master mixed disc R with pre-grooves. With regard to the latter, in the embodiment shown in FIG. 12, the channel created from the beginning of the main beam 102 will be deepened by the effect of the subsequent channel writing beam 103 (that is, it is caused to activate in light The layer 112 occupies a position lower than its upper surface 114), and does not significantly change its lateral cross-sectional shape. 20 A variety of devices that can form and use these beams are described. Figure 13 depicts the main embodiment of the present invention, which corresponds to the use of a gas laser and external light modulation! A device for making a hybrid disc master as shown. The output beam written with laser 7 enters a beam splitter 100 and is divided into two beams = 0 and 121 here. Beam 120 is the primary writing beam and beam 121 is the secondary beam 25, the former is the source of the data writing beam 102, and the latter is the channel writing beam 103 ------- ---- 40 -__ A paper size is applicable to China National Standard (CNS) A4 specification (21 × 297 Gongchu) 200419559 A7 B7 V. Source of invention description (39). The main beam 120 can be used to create ROM pits and can also be used to make the main part of the R-band slot (or the R-band slot itself, provided that the lateral direction is not changed as described above without using a secondary beam Profile structure). One of the beam splitter 100 inputs is a signal 104 which defines a desired intensity ratio of the two resulting beams. These beam splitters 5 are well known in this technology and may be based on, for example, the following: (1) a polarizing beam splitter combined with a half-wave plate; (2) an acousto-optic Deflector (1GD〃); or ⑻-photoelectric retarding || combination-polarized beam splitting state. In the preferred embodiment, an A0D beam splitter is used, and another input, not shown in the figure, establishes a deflection angle, resulting in the desired radial separation of the two resulting beams on the surface of the master hybrid disc. The main beam 120 enters an optical modulator 11 whose function is controlled by the waveform shaping circuit 31 mentioned above with reference to Fig. 1, and its effects are also mentioned above. It should be noted that there is an additional input-format for the waveform shaping circuit in FIG. The latter is merely an input caused by the specific operation the device is used to perform, whether it is a 15 data mark format or a continuous or discontinuous channel cut or other applications that the skilled person may use with the present invention. The nature of the input and the waveform shaping circuit that processes this input will be specified on the basis of what is specified within the competence of a circuit designer familiar with the art based on the particular application. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, one of the waveform shaping circuits 31 outputs a signal directed to the beam splitter 20 131 to control the degree and timing of the beam splitting operation. In some applications, beam splitting occurs approximately continuously. In other applications, it may be desirable to divide the input beam into two outgoing beams intermittently. This effect can be controlled by the waveform shaping circuit 31 as shown, or by other inputs to the beam splitter or by an input to the source of the intensity ratio input of the beam splitter 100. Because the purpose of this 25 input is clear, it is assumed that ordinary practitioners can easily think of other ways. -41- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 public love) 200419559 A7 ___ B7 V. Description of the invention '-— To achieve this. The modulated main beam 122 passes through the main ATIP deflector 15 controlled by the jack input 151 after leaving the light modulator n, which will be necessary in a conventional manner (see also the description of Figures 14 and 20 below) The ATip modulation is introduced into the beam. The 5 secondary beam 121 can be directed to another optical modulator 123 (which is also controlled by the wave shaping circuit 31 via line 133). Since the secondary beam is expected to create only a wide shallow channel (in the ROM or R zone), only the secondary beam modulation will typically require intensity and on-off control (both Both are provided by the beam splitter 100) and the spot size control (provided by the inverted telescope 130, see below). In this case, the light modulator 123 is not needed or the light modulator is turned off. However, in some formats, further modulation of the secondary beam may be needed or desired, and thus has the optional secondary optical modulator 123. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs After leaving the light modulator 123, the secondary beam 124 also undergoes Δτι modulation 15 in the manner of passing through the secondary ATIP deflector 155 controlled by the ATip input 156. The modulated beam 124 is pointed at an inverted telescope 130 after passing through the secondary ATIP deflector 155, the purpose of which is to reduce the direct control of the beam by a desired amount based on the beam width ratio input from line 132 to produce One output beam 125. The effect of the inverted telescope 130 is to make the spot size of the secondary beam on the master disc surface finally selectively larger than the spot size of the primary beam. 20 It should be considered that in the main embodiment shown in FIG. 13, a gas laser is used to create, write, and write the incident beam, and the modulation is performed outside the laser itself. The splitter 100 is an acousto-optic deflector (), and the secondary ATIP deflector 155 can be received into the beam splitter 100. In this case, the ATIP input 156 constitutes one of the inputs to the beam splitter 100, and this 25 input, together with the secondary beam 121 emitted from the general deflection input upside down, presents the desired -42. This paper size applies China National Standard (CNS) A4 specification (210 X 297 mm) 200419559 A7 B7 V. Description of invention (41) Radial displacement and ATIP flutter. Since the main beam 120 (i.e., the zeroth-order π beam) is not exposed to any deflection in the beam splitter, it will also not receive the ATIP modulation in this case. Therefore, the main beam will still require independent ATTI p modulation, which must pass through the ATIP modulator 150, as in the previous case. 5 The main beam 122 and the output beam 125 are combined in a beam combiner 135, whose purpose is to calibrate the two beams for subsequent processing. The beam combiner is completely conventional and may include a dielectric beam splitter. Alternatively, a semi-silver mirror set at an appropriate angle (approximately 45 °) may be used. The two emitted beams pass through a condenser 14 which expands the channel to write 10 beams (from secondary beam 125) and data beam 102 (from autonomous beam 122) and expands the beam. The two beams are directed to an objective lens 145. It is recalled here that the inverted telescope 130 has narrowed the modulated beam 124 to produce an output beam 125 directed to the condenser lens 140. Because of this narrowing effect, the obtained channel writing beam 103 does not completely fill the input pupil of the objective lens, effectively reducing its M, and the result is that the beam will not focus 15 to fill the objective lens like an image The data beam 102 is as small as a light spot. Therefore, when the disc 1 is rotated by its shaft motor 3 (the spindle motor is controlled by an appropriate speed control 5 to ensure a strange linear speed), the relative direct control of the two beams on the disc surface 43 will cause A channel 75 is formed, and the width of the channel is larger than that of the pothole 50, as shown in the printing of the employee consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The actual size of the 20 final beams will depend on the parameters of the upstream control of the financial control, especially the reduction ratio of the inverted telescope 13Q, the lens ⑽, and the parameter cut selection of 145. In the same way, all or a selected part of the necessary optics will follow the picture in terms of function and purpose! It is supported by a device (not shown) similar to the carriage 21 shown in FIG. 2 or other components that move sideways to move 25 opposite to each other between the beam and the axis of the disc. ----- -—— 丨 _ " 43 " ____ ^ ,, this paper size _ + _ Jia Xian (cns) A4 size ⑽ 乂 297 mm; '~ --- 200419559 A7 B7

on. However, these measures are of course based on the present invention and related techniques and are within the knowledge of practitioners. FIG. 14 illustrates the same structure of the present invention as shown in FIG. 13, but with reference to the device shown in FIG. 2, in which a diode laser is used. The discussion about FIG. 13 is also applicable to the content shown in FIG. 14. The difference is, of course, the content about the optical modulator shown in FIG. 13. 13 and 15, the channel writing beam 103 is focused on the active surface 43 of the disc 1. However, because the writing beam of this channel is relatively small να, its spot size is larger than that of the main beam 102, thereby creating a channel whose width is desirably larger than the data pit. In hybrid CD applications (where the pit width is about 0.5 microns), the spot size of the 10-channel writing beam on the disc surface may be about 1-2 microns. During the programming of the R τ pregroove, the waveform shaping circuit is turned off because the pregroove is mainly made with a constant intensity beam. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs In the embodiment shown in Fig. 14, a first light deflector 150 is inserted in the path of the main beam 122. The purpose is to selectively oscillate the beam 15 through the action of the input sent through the line 151 to generate a trembling main exit beam 162, which will obtain a write-in incident beam 102. The ATIP input will contain all the parameters for a correct jitter to import ROM data and R with prefabricated grooves in a manner known to those familiar with CD-R masters, as previously described. A second optical deflector 155, also controlled by the same ATip input signal (through line 156), similarly introduces the desired jitter into the beam 20124. In this way, an output beam 161 will be generated. After passing through the inverted telescope 130, this beam will obtain a secondary outgoing beam 163, and then a channel writing beam 103 will be obtained. Preferably, both the light deflectors 15 and 155 are AODs. Of course, the deflection effects of the two must be carefully synchronized and weighted, and the best results are obtained when the ATIP dither signal to the optical deflectors 150,155 comes from a single source, as proposed earlier.

Description of the Invention (43) ~-Those skilled in the art will understand that the writing beam can be changed in one channel based on the present invention The intensity of the resulting channel changes correspondingly. This change in beam intensity can, for example, be controlled by selectively controlling the intensity of the output beam 161 directed at the inverted telescope 130 (the secondary exit beam 163 is emitted from this). This method is easily achieved. This series 5 is ordered by selecting the laser power and intensity ratio input sent to the beam splitter 100. In any case, the final intensity of the beam written in the channel can be easily selected to be provided in the active layer. An effect ranging from the creation of a full-depth channel as described above to just slope removal measures. The latter would require the beam intensity to be sufficient to produce a thermal threshold within the moving active layer 43 that is only slightly below its thermal threshold. Level of heat generation, while the former would require a suitably high intensity of 10. Such adjustments to produce any desired results would be within the capabilities of the average practitioner based on the present invention. Familiar with Dye-Polymer Optics The data recorder will observe that all channels except the channel created by the channel writing beam will tend to have a fox-shaped base (viewed on the cross section transverse to the channel axis), all other aspects are the same. The beam written in the main pit b, the intensity cross section of the roughly circular beam will be distributed along the diameter of an Airy Disc, with the maximum intensity closest to its center. However, in an application, it may be expected There is a relatively flat bottom channel, as shown in Figure 8. _ Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, it is possible to improve the alignment by providing a consistent / 8 phase depth along the base of the channel in the final hybrid disc. 20 Figure 15 shows a channel writing beam in the channel writing beam and the cavity writing beam by shaking the channel writing beam ~ trembling during the forced relative movement (that is, transverse to the axis of the channel) This method of generating a relatively flat bottom channel is produced in a rapid vibrating manner. It should be noted that FIG. 15 is directed to the structure shown in FIG. 13 and the latter is related to that shown in FIG. I, which uses a gas mine that requires external light modulation. Shoot. I am sure that I am familiar with this skill The staff can easily apply what they don't focus on to the device shown in Figure 2 (that is to say, it can be used on the size of the paper, and the financial rewards are in millimeters) ~ 200419559 A7 B7 5. The embodiment shown in the invention description (44)), in which a diode laser is applied based on the present invention and the principles well known in the art. Figure 15 is actually a dual mode device that can be used for CD or hybrid disc mastering. In the CD master production mode, the ATIP h number 5 transmitted via lines 151, 256 is released, because the CD master production does not need to generate chatter. The ATIP signal is activated in the production of the second disc of the hybrid disc master in the R-belt prefabricated slot produced by the hybrid disc master, but the light modulators 11, 123 are only in the process of all or ministry formation. Sends a beam of selected constant intensity. In either case, the input given to the light deflector 155 by the line 260 originates from the general signal combination circle 2 plus its input is the one that can activate the signal at that time. All the components shown in FIG. 15 have been mentioned in the foregoing. The only difference between _14 and Tuqiao ’s example is that the material used in the optical modulator 11 and 123 is shown in Figure 15 on the real surface of the gas laser. Outside) is an additional dithering input to the light bias 155 via the line 231. In the hybrid CD mastering mode, this input causes the optical deflector to perform the complex beam i of the secondary beam 124, which is a combination of one of the manual jitter and a faster jitter. The reason for this dithering is that the circuit oscillates with the output of one of the circuits 31 in general practitioners' ability. The internal square confession and the output of the beam shaping beam combiner 135 are composed of two heavy beams which are irradiated to the objective lens 通过 through the condenser lens 140.

Two images-the same composition-a single widened laser beam irradiated on a light-activated surface. This embodiment is depicted in FIG. 16, which is based on FIG. 14 (diode laser embodiment): soil foundation and its towel The relative clustering of the beams has been greatly separated to clearly show it. Select this diode laser implementation_ 为 求 丝It is simplified, but it should be understood that a gas laser embodiment with an external light modulator may be used as a basis for Figure M, because the nature of the beam source is not important to the present invention. Now, refer to Figure 16 The channel writing beam 124 is emitted from the beam splitter 100 and passed through an optical device, and the optical device is preferably designed as a custom-designed diffractive element. Its purpose is to divide human light into mutual financial polarization. The moving L pair of outgoing beams 201a, b. Those skilled in the art can easily change it to a pin silk purpose. As shown in the illustration in Figure 16, since these outgoing beams each have an _: approximate riding intensity cross section, its A small amount of mutual displacement will cause a beam of contact, whose knife cloth (in the section view of the displacement axis at / σ) is approximately rectangular. As shown in the figure, the slightly displaced beams 201a and b emitted by the beam combiner 135 Combined with the main beam 122, the output of the beam combiner passes through the condenser lens 14Q and then passes through the objective lens 145. One beam 102, 202, and 203 is thus focused on the active surface 25 surface 43 of the rotating disc 1. Beam 1⑽ is the predominantly written beam, while beams 202 and 203 —struct-47- 200419559 A7 B7 V. Description of Invention (46)

Write the beam into the channel. These three beams are focused at points 211, 212, and 213 on the active surface, respectively. It should be understood that FIG. 16 is not drawn to scale to show the details, where beams 202 and 203 will actually partially overlap on the active surface, as shown in the illustration, and beam 102 will be focused in the center of the combined beam. If the 5 plane view of the grip extension is viewed from a micro perspective, the result on the surface will be an elliptical light spot with an intensity at the center (the pit is written here) is stronger than either side (thereby creating a channel ). The embodiment shown in FIG. 16 is based on the pit writing beam 122 and the groove writing beam 124 being separated by a beam splitter 100. However, similar results may be obtained with a single beam, as shown in Figure 17.

Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives. 10 In this example, as in the embodiment shown in FIG. 13, the laser 7 emits-a beam 12 0 is guided through-the light modulator U 'this converter receives, Shaping circuit & control 'The input of this circuit may include speed, format and data input signals. The output beam 122 of the optical device is directed to a light deflector 221. The light deflection boundary is very similar to the light modulator 15 shown in Fig. 14 and mentioned in this paragraph. The second purpose is similar: to transform the beam 122 into a wheel exit beam that selectively trembles with respect to the disc in a radial direction (ie, the up and down direction as shown in FIG. 17). This selective dithering is caused by the dithering output signal 231 from the waveform shaping circuit. The instantaneous vibration of the basin is synchronized with the instantaneous amplitude of the beam 122 emitted from the optical modulator. The tremor signal is input through a conventional electronic addition device 220 and -200. The output of this addition device constitutes the input to the optical deflector. The deflected beam j 222 passes through the condenser lens 14 and the objective lens 145, and becomes a moving point 280 of the focused beam on the active surface 43 of the sheet 1. This beam (the beams' 270 and 207 are shown in the figure to indicate their motion) depicts a complex radial trembling pattern on the surface of the rotating disc, creating the desired characteristics (pits, channels, etc.) . Because the trembling L is made by the same waveform shaping circuit X297 mm as the control optical modulator) binding line 200419559 V. invention description (π 31 produced, the input to the waveform shaping circuit will be determined at the same time at the disc operator During continuous rotation, the instantaneous spot meridional position of the beam 270 on the active surface 43 is written. Therefore, an appropriate round = is generated by the waveform shaping circuit (this Within the range of capabilities that the literature can make), it can burn extremely complex patterns spirally in the active surface of a rotating disc. If a master is made from a master disc made in this way Then it can be converted into thousands of reproductions. For example, this technology may be used simply to form more 10 15 20 precise ROM pits for a master hybrid disc, where the beam passes the appropriate optical parameters and author The choice of the beam wavelength narrowly focuses into a very small spot. When the disc is rotated, the tiny spot is within the range (relative to the disc in a radial direction) very quickly ^ This range is equivalent to writing Personal information The width of each system. The face shake can be finely changed as the desired width of each pit along its length changes during writing. Between the pits in the track, the light modulator Beam until the next pit starts.

In this case In the middle, a second tremor signal is superimposed to form a tremor signal (that is, summed with the latter), in which the second signal: the groove on which the sequence of flat ground will reside on the disc. The depth of the tract is In the trough-type reading beam, incremental shouting (through its production — the heat of the moving marrow increases the amount of heat flow), and its width is determined by the range of Yan Shao. As mentioned earlier, by Properly controlling secondary tremors-49- 25 200419559

The amplitude printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs can cause any actual state of affairs to end when the contract is concluded. Roads only occur between potholes. ^ The hole formation signal is-the channel formation signal, as it is added to the known U example. But A: Γ = formation of a tremor signal is only activated when a tremor signal is formed in the pothole: when it is triggered, or overlap is trapped to promote reluctance, but its sundial and shape are set so as not to cover the pit / land transition and thus damage it And HF detection. In the R-band of the master mixed type, the continuous groove is created by providing a single dithering signal with a fixed dithering range and appropriate intensity, and the ATIP facial motion signal is superimposed on the dithering signal. As mentioned earlier, this mode is activated by a stylized switch component, which is within the ability of the skilled person. In all of these examples and modes, the tremor range and beam amplitude can be controlled by conventional components to produce almost any desired geometry of the ROM cavity and R-band pre-groove. In addition, the application of the trembling embodiment of the present invention can be extended to those skilled in the art based on the present invention and related documents to improve the PR mastering technology improved in a manner that accurately controls the two-dimensional range of photoresist exposure. These techniques may also be applicable to eliminate some of the inherently rough nature of PR procedures and / or reduce or possibly even eliminate chamfer discontinuities in the transverse cross-sectional shape of the resulting pothole. In order to facilitate the description of several embodiments of the present invention, Figures 13, 15 and 17 are based on the use of a gas laser as the writing beam, while Figures 14 and 16 are based on the use of diode . As mentioned earlier, the gas laser requires external modulation, and in the diode laser embodiment, the laser itself acts as an addition element that combines the various input signals to produce the desired written beam intensity distribution. Of course, each embodiment can be represented by the same number of drawings with the implementation of the gas laser and the diode laser.

Therefore, for example, to figure 13: mother = beam therefore It can be based on the fact that the embodiment of the beam beam scale component is based on the reason that the two beam beams-the beam is selectively focused on the position along the data_different from the other beam, thereby The time difference between the data writing beam 102 and the channel writing beam ⑽ is applied to the write-write time.

Again, it is stated that the object of the present invention is at least to some extent removed (or essentially) (Reduction)-generally applied in the dye-polymer method. Except for US Patent Nos. 5,741,627 (Cubit et al.) And 6,022,6 which solve the problem of slopes in a completely different way from the present invention. No. 04 (Del Fer et al.), All public documents do not seem to have a substantial discussion of these slopes, and these slopes naturally form two-dimensional features in optical recording media by thermal burning procedures. It is produced in procedures (such as dye-polymer method). There is a lack of literature on slopes formed in thermal programming procedures. Those skilled in the art will understand the reduction in slope height after considering the content of the present invention. Will improve HF detection, and will especially realize that when these slopes are almost completely eliminated -51- This paper size applies the Chinese National Standard (CNS) A4 specification (21〇X 297 public love) 200419559 V. Description of the invention ( 5 0) A substantial improvement that can be achieved. I have found that by using the technology of the present invention as disclosed in this specification, these slopes can be reduced to the point where it is very difficult to detect their vertical deviation from an index level. In other words, by applying the techniques disclosed in the present invention, and by adjusting the available methods in a class 5 similar to the general techniques in mastering and manufacturing techniques (previously and below), Parameter setting, it can be expected that a practitioner can create a master of net copy hybrid disc with almost no slope that can reproduce three-dimensional features (such as ROM data pits and R γ pre-installed grooves) through thermal programming. Hybrid disc. ° 10 The measurement starts from an index level (which is defined as the slope with respect to its radial limit, which is printed by the Consumer Property Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs-the vertical position that starts to rise: for example, 177 in Figure 7). Reverse distance of the slope height (h, see Figure 7) and pothole depth (d, see the figure, after I sent the "CD-brain master making towel towards the thermal burning technology (such as dye -Based on polymer method) will lead to the formation of slopes, where the ratio of slope 15 冋 to the depth of the hole (ie h / d) is at least 20%, which is usually greater. By carefully based on published literature Using conventional methods, I still cannot reach a ratio of less than 20% for this format. My view_ If a thicker dye-polymer layer is used in the production of mixed CD masters to create deeper potholes (because -The dye layer will be spin-coated on the net copy hybrid disc to create the final 20 hybrid discs), and a lower ratio can easily be achieved. But this is not because the slope itself is so low, in fact, Because it has deeper master ROM ROM pits than the same slope height, Of course, a lower ratio will be obtained. However, since the production and manufacturing of hybrid disc masters has more variables than the general cD_rom master's production, it will be very desirable in this regard to reach the highest possible value of 25. Therefore, the slope height reached by the conventional CD_R0M master production method-52- 200419559 Α7 B7 V. Description of the invention (51) " ^ ~ will not produce a sufficient result even if it is converted into the mixed disc category High figure of merit. Therefore, the technology described in the present invention that can further significantly reduce the slope height ratio is necessary to achieve an ideal result. However, optical data recording by the PR method usually does not show a slope of 5 at all. , Because this method is not a heat treatment process and no material punching occurs due to the method when the three-dimensional mark is formed. Although the heat treatment process (such as the dye-polymer method) is inherently easy to promote the formation of slopes (this is described by the foregoing embodiment of the present invention) However, these procedures are different from the PR method, and the fact that as long as they are well controlled, it is easy to produce smooth surface pits with continuous slopes. 10 Although However, we have observed that the adhesive structure of the polymer used to form the master disc dye-polymer recording layer has a profound effect on the extent of the slope that can be generated in the mastering process of optical data about CD and DVD mastering. I have not observed that these steps are particularly valuable in the production of hybrid disc masters. In any case, we still have to refer to the parent application for a complete discussion of this issue. 15 Of course, in the disclosed method, The write beam produced by the master of the hybrid disc is printed and read by an employee consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, which originates from a source other than laser. For example, an electron beam or an ion beam can be used. And there is no doubt that there are other beam sources that can be applied to the present invention, some of which may be left for future scientific and technological development to make it possible. However, any and all of these laser alternatives are also within the scope of the present invention, and are carried out by necessarily modified clothing and / or methods within the skill of those skilled in the art to deal with such alternative energy sources. Its implementation also constitutes equivalents that do not exceed the claimed scope of the present invention.

The resulting metal mold is then removed from the master and the Z master is discarded. The film making mold constitutes a mold by which a duplicated disc (in this case, a net-replicated hybrid disc) is obtained by using a high-temperature and high-pressure shot region shape. After this, suitable dyes as mentioned in the CD-R literature are spin-coated in a conventional manner on each net replica and allowed to cure. As in the case of osmium manufacturing, the acoustic coating-thin reflective layer is then applied and then a protective layer is applied to produce the final private disc. Dye manufacturers such as Ciba (see above) often include very detailed instructions in their product manuals and instructions for use, such as how to use the specific wood of the scrap merchant, to enter the ordering process. The practitioners refer to this method of making money materials to learn more about spin coating and related issues. Each of the preferred size ranges of the net-reproduction hybrid M and most Weihe-type discs produced in accordance with the present invention is listed below with reference to Figs. 19-23.

Description of the invention (54) Measured from the level 324; and as mentioned below, in the data presented in Figure 23b and Figure 25 and Tables 2 and 3 , D'm is measured from the effective level surface 334, which descends from the ROM channel. The reason for this obvious difference is that when the potholes are almost as wide or even slightly wider than the ROM channel where the potholes were made (as shown in Figure 25 and 5, the figure generally shows the data shown in Table 3), The pothole starting level 324 and the effective flat level 334 are essentially overlapping.

Another possible cause of confusion may lie in the way in which the width (ie, the range of lateral dimensions) of each feature is measured. As mentioned earlier, the width of the pothole or ROM channel is measured Φ 疋 at a depth halfway down (or up) from the vertical level of the feature. For example, referring to FIG. 23a, the half-depth 333 of the ROM hole 332 is halfway from the starting level 324 of the hole to the bottom of the hole, and the width Wplt at the half-depth is at that point. Measured laterally.

Alternatively, the lateral extent of a feature is from one side of the feature to the opposite side of the feature ', including any amount of displacement of the feature in the opposite vertical direction (such as due to a slope). For example, in Fig. 23a, the lateral extent of pothole 332 is the lateral distance from one side 335a of the soil hole to the opposite side 335b of the pothole, that is, the self-pit on one side from its wheel gallery. The hole starting level 324 rises to the point where it returns to the level on the opposite side. Similarly, the lateral extent of the trough criminal is the lateral distance from one side 322a of the trough to the opposite side 322b of the trough, that is, its profile from the height of the effective level surface 334 to its back To this level ------- " 56 ~ ____ The paper ruler_Cai_ 10 15 20 25 200419559 A7 B7

Description of the invention (55) It should be understood that for a particular selected dye and reproduction conditions, the preferred size range is significantly smaller than listed in Table 1, so as to achieve the best overall performance and figure of merit in the final hybrid CD. However, research conducted after September 25, 2002 (5th of application # 27) using materials and techniques described in application '〇27 has shown that it can be used to achieve a wider range of acceptable parameter values .

These data are produced in accordance with the manufacturer ’s instructions for use of UUragreen MX dyes in addition to what is disclosed in which application number, and are listed in Table 3 below. It should be understood that these data are measured from the production mold. The characteristics b of the disc copied from these production dies may be about 5% less. Depth is calculated from the effective level (shown as 334 in Figures 23 and 25). The width is measured from half depth and is also shown in Figure 25. These pothole data are values obtained from potholes with a longer run length (e.g., about 9_ητ). The shorter pits are expected to exhibit smaller pit widths. With reference to Table 3 below, it should be understood that in this case and in most other cases, the r-slot and the groove-slot k dimensions are the same, because in fact the ruler slot and the groove are usually -57- Chinese Standard (CNS) M Regulation 袼 ⑽χ Tearing Public Fantasy 200419559 A7 B7 V.

In particular, although the data in Figure 5 does not show that the lateral extent of the pit is greater than the lateral extent of the corresponding channel, the ROM pit width in Example 2 is ho% of the ROM channel width. These data are taken from a hybrid disc with a holding distance of 1.6 microns and a total capacity of 650 million bytes. In the case of a holding distance of 微米 1.5 micrometers (this is necessary for a hybrid disc capacity of a total of 700 million bytes), if the r0M pit is wider than the ROM channel, a 10 Crosstalk problems. In any case, these data do prove that by adjusting the grip distance, it is possible to have ROM pits with a width as high as about 10% of the width of the ROM slot in which they are located. This situation is depicted in Figures 24a and 24b, which are a simplified scan of the bandit channel (Figure 24a) and a simplified scan of the pothole (Figure 24b). When 15 such potholes are created in these channels in the master hybrid disc, the result in cross section is like there is only one pothole, and the depth of the pothole is increased by the channel in which it is located. Here, the pothole 334 in FIG. 25 is taken as an example. Therefore, the recent research mentioned above has shown that by using the materials and technologies disclosed in Application No. 27, the potholes can indeed be slightly wider than the channels without affecting the overall performance and superiority of the hybrid CDs obtained by replication. Values cause harmful results. This is the result of the great flexibility provided by the disclosed method 20. However, I continue to believe that if the R⑽ pit-to-cave ratio is -58-, this paper size is applicable to the Chinese National Standard (CNS) A4 specification (2i0x297 mm) 200419559 A7 B7 V. Description of the invention (57) It is narrow in the beautiful channel and it will Presents smaller crosstalk problems and will provide overall and better results for most deer applications, especially cases involving smaller hold distances will be wider or wider than ROM pits compared to the ROM channel where they are located The case came well. Fig. 23b depicts-the ROM hole pits which are substantially narrower than the ROM channel 32m where they are located, for comparison with the structure shown in Fig. 25. 10 15 20 This technique is unknown, (: D-CT cell reading f turns the binary data value of the two-phase (ie, crystalline or amorphous) material based on the reflectance detection, where Binary, and zero represent one of the two phases, and binary, 'one' represents the other phase. Therefore, the depth of the ROM hole in the CD-RW hybrid disc is quite small and must be far away. Less than 250 nanometers, maybe even less than 90 micrometers or less. In addition, if it is applied with a very thin future CD-R dye layer, it may be tested in the final CD-R hybrid disc. Fortune transfer type burned pits that provide sufficient HF and PP response when read from the second side. For these thin dye layers, the required pit depth in the substrate must also be much less than 25 nm. It is found that the preferred relationship of the depth of the corresponding feature is in the range of 3G% to 8G% before and after the dye coating, and it is preferably in the range of 5 ()% to G. For example, it is preferably DRGr㈣ 30% to Na; and preferably 30% to 80% of D-, in which the range of 5 to 5 is the best. However, although the latest The research shows that u is equal to or even slightly less than W.

10 15 Value printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. As is known and understood by those experienced in this area, each system must provide the highest possible figure of merit through the best bias, and this is especially true in the case of hybrid mastering and manufacturing. The net copy of the free trial financing meets the above requirements, and the county and county are optimized to the extent that they have not continued to the spin-coating stage. If the above criteria are not met, any other step in the mastering phase or throughout the upstream manufacturing chain that is considered to be causing unacceptable results can be appropriately adjusted for one or more of the available parameters. — Generally speaking, first adjust the mastering parameters, as this is just a matter of changing one or more adjustable inputs. This parameter adjustment key is inherent to Puer's feedback optimization technology manufactured in GD, and includes: (1) making a master; (2) copying in a complete set of k-line from start to finish ' This manufacturing line is best to be in the same room. ⑶ Analyze the copy port 0 and note the way and extent that these copies do not meet the applicable specifications or requirements; ⑷ readjust the master production parameters; ⑸ generate subsequent copies for supply Analyze, and (6) repeat this procedure until a replica with the desired characteristics is consistently obtained. In the end, the final hybrid disc and the post-burning hybrid disc must meet the Orange Book specifications, and the corresponding beauty district must-have Naner Orange Peel # Specifications⑽Red skin see the requirements of Geyun / oral 4 The route is further optimized to meet some specifications, and the figure of merit is maximized to ensure that these specifications will continue to be met. Each manufacturing line variable may need to be adjusted to achieve the desired result. For example, one of the most common manufacturing variables encountered is the relative ability of a replication (ie, molding) device to apply consistent pressure from the center of a net copy disc to its periphery: a radial reduction in pressure may cause a net copy mix The ROM pits of the disc are easy to make, and the outer part of the replica disc becomes shallower. The aforementioned US Patent No. 5,608,712 should be applied to the problem in a manner similar to the application of the slope trimming function mentioned in 200419559 A7 B7. This is only the fact that Wei has different optimization challenges in different manufacturing lines, and there is no other way than to properly analyze the final hybrid disc and adjust the mastering and manufacturing parameters accordingly. It should be understood that this development_improvement can be observed not only from master mixed discs, but also from production dies copied from such masters and from or directly from such masters. The resulting structure (net copy hybrid disc or possibly other intermediate structure) was observed. Since all such reproductions (whether net reproductions or final products) exhibit the improved features of the invention, these are all within the concept of the invention. 10 As mentioned above, the invention is of course not limited to hybrid CD manufacturing.
