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.

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-shaped prefabricated groove in the recording layer includes a series of 5 inserting unmarked or different marks 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 (MO) discs, where the data marks are essentially two-dimensional (but CDs -Except ROM mark in RW master and 5-5 tigers which can be copied in M0 disc). CD-RW hybrid discs and M0 discs are briefly mentioned 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. (absolute time in pre-groove) The timing data is added to the smooth spiral track. In the case of CD, this Ατιρ timing data includes a modulation at 22.05 kHz (nominal value), with A radial sinusoidal carrier with an amplitude of ± 30 nm (nominal value) relative to the longitudinal axis of the spiral prefabricated groove without flutter. Although the data in the recording layer has its ATIP flutter and its inevitable spiral structure, it can be regarded as a large number of closely spaced, roughly circular paths, each path containing a large number of continuous three-dimensional data marks and intermediate flats. In some application orders, a specific data execution or execution part may not be a complete circle, in a sense its T can only occupy the __- arc on the cymbal. However, in this manual, the parts of chess shape and ® shape shell material or practice are interchangeably referred to as circular material practice. Because these roughly circular paths / roads have a circumference of each path that is larger than the size of the mark and the land, a small string of marks and intermediary flat ground will look like a linear 15 20 25 This paper size applies to China National Standard (CNS) A4 (2 Sichuan X 297 mm) [242198 A7 B7 V.

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 series of linear marks and ground in a vertical series, but at the macro-view scale It is a circular path of great heart. The appearance of the data mark is usually like a long, slightly expanded three-dimensional mark that is constrained between the reflective layer and the substrate in a prefabricated groove. Each symbol contains at least a substrate and a reflective layer One of the distortions. The difference between the characteristics of the material 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 the modulated laser beam, and additional objects also occur. Physical and chemical changes. The intensity of the laser beam is adjusted according to the coded data to be burned, and each obtained mark and each intermediary flatly represent a part of the data. In the CD-R burning operation, each data The run length of δ # and the ground (run ieng ^) corresponds to a pulse of 3τ to Η? duration. Due to the use of αν, all the marks corresponding to the same nT value are ideally the same length and peacefully. The data may be subsequently retrieved selectively (ie, decoded and processed) by a CD player. Ideally, a CD player will not be able to distinguish between a CD-ROM or a CD-ROM, such as software CDs) read data marks, so data can be retrieved from each format in the same way.

As will be explained below, the method of pr Early disciples of hybrid discs will produce this horizontally structured R-belt prefabricated groove. It was found that these shallow appearance features created by the PR method are usually generated from duplicate discs, 'noisy 〃' Data output readings, because of the inherent roughness in the side photoresist layer and the greater sensitivity to laser noise from the writer. Indeed, due to the discontinuity process of the PR method for disc: plate production, it is usually Will produce a one-dimensional appearance with a coarse sugar surface. This damages the fineness, because the amplitude of the signal is affected by the surface. This problem is related to U.S. Patent No. 5,696,758 and others, and U.S. Patent No. 6,212 to Ha, et al. Section 158 will explain further. •…, what, the thickness of the photoresist layer and the degree of exposure (and the obtained pit or pre-groove ice) are usually selected by those skilled in the art—the way to obtain the best detection from the replica. As mentioned earlier, the width of the pits and prefabricated tanks is determined by the power of the burning beam and the effective width of the mosquito. The latter is based on the wavelength of the laser and the numerical aperture (, NA〃) of the focusing member. The shape of the transverse cross-section of the pit, whether trapezoidal or triangular, may be controlled at least to some degree by the optical characteristics of the photoresist material, the etching process, the writing beam power, and the specific focusing structure selected, as described in patent documents. Described. Finally, the length of each completed r⑽ pit is mainly determined by the continuation time of the corresponding EFM (or EFM Pius) data pulse, as is the length of each intermediate flat. It is mentioned again that no matter what the application is, the PR method is essentially a one-minute process, and even if the photoresist is completely exposed, it will inevitably be issued on the surface of the side wall of the pit.

Description of the invention (U) The desired HF is optimized to an effective pothole depth equal to λ / 4 (note that each pothole usually has a dye-polymer punch out This is achieved under the conditions of the arc base caused by the program), where λ is the wavelength of the read beam (usually laser) in the substrate material (because the disc is usually read from the second surface). This will be reversed at 5 A phase shift of 7Γ (180 °) is caused in the incident light, and a small amount of incident light that does not diverge due to diffraction is effectively offset by interference. 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 accuracy of the pothole and flat land length. Detection—that is, accurate HF detection. 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 Q) application, the “directional PP detection” is only a comparison of the amplitude of the light detected on either side of the longitudinal service axis (whether it is in a hole or flat area). When the ρρ detector receives more reflected light on one side than the other, the ρρ 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 ρρ detection, not a λ / 4 effective channel depth and corresponding redundant phase shift that optimizes HF detection. As mentioned in the previous section, a similar λ / 8] / 4 dichotomy exists between PP and unrecorded channel reflectance in CD-R and DVD-R applications, and other optical recording applications (such as hybrid (CDs) There is a very similar dichotomy. A newly-approved European patent Ερ969〇8632 · 丨 (hereinafter referred to as Schoofs) has improved the ρρ detection in optical data discs to a certain extent25 (obviously a dye-polymer recording) and hopes not to HF detection will be sacrificed too much _____ -15- This paper size applies the Chinese National Standard (CNS) A4 specification (210 χ 297 mm) 1242198 A7 B7 V. The problem of measurement (M) measurement. The proposed solution is to maintain the intensity of the writing beam between the writing pulses at a level just above the thermal threshold of the mobile media. This will create a shallow and narrow channel in the flat area connecting successive pits. It is hopeful that the quality of the pit can be improved in a state with minimal negative effects on the detection accuracy of HF (that is, pit / flat transition). The signal strength of the PP between holes. To some extent, this method appears to meet the ρρ optimization criterion 'where the flat channel can be made to an effective depth of approximately λ / 8 (in the case of a hybrid disc, its effective phase depth Will be about / 8) again. However, since the intensity of the writing beam is reduced to near the thermal threshold, the resulting flat channel must be quite narrow. But this actually hurts the PP detection, because another feature of the pp / HF dichotomy is that the best PP detection is achieved with a channel that is wider than the channel that would optimize HF detection. In addition, Schoofs has not explicitly addressed the problem of HF detection. In fact, the logical extension of what Schoofs said will be to further increase the beam intensity between the pits and widen the channel in the hope of better alignment. But in fact, it will damage the PP detection by deepening the channel, and it will also damage the HF detection because it makes the pit / flat transition area more difficult to detect, thereby negatively affecting any ρρ improvement provided. pin.

In terms of hybrid disc manufacturing, very similar problems can also occur according to the methods described by Nakagawa, Yanagimachi, and Ha, which will be briefly explained below. 20 Which method and method (CD-ROM 'hybrid CD, etc.) are used to create a master disc (such as the PR method or the heating method, such as the dye-polymer method) are only the first in the disc manufacturing process.

Description of the invention (15) Into a metal stamper, from which polycarbonate daughter discs are moulded & if fully skilled and handled with care, this stamper will almost exactly mirror the master and the resulting The "Clear replica" hybrid disc will also be almost a true copy of the master. It will present the recorded ROM data in the band τ, and will present the necessary CD-R pre-grooves in the r band. Failure to optimize the overall disc manufacturing line through a feedback loop process (see below) by continuously testing the final (processed) hybrid disc and adjusting the mastering parameters accordingly The production mold and the mirror of the master are reasonably well mirrored. The net copy hybrid discs are very similar to the master, but the ROM data marks and prefabricated grooves do not show their cross-sectional shapes in the master. The ultimate hybrid disc. The latter (and the hybrid discs that will be burned later) must meet the Orange Book specifications (and the Red Book specifications of the relevant ROM area included in the Orange Book). There are no specifications for master hybrid discs or net copy hybrid discs, as only the final copy 15 will have commercial attention. We must not only optimize the mastering process to produce a final hybrid disc that meets manufacturing specifications, but also maximize its figure of merit (Figure 〇f MeHt). As is well known in the industry, the figure of merit is a measurement for the applicable specifications (such as the amplitude printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Investigation, the amplitude detected by the PP, the amplitude detected by the PP, and the crosstalk between radially adjacent parts of the data. 20 minimization, etc.) weighting function for overall consistency. The figure of merit increases as the observed parameter value of the final hybrid disc in the relevant specification category approaches the center of the acceptable range of each of these categories, and maximizes when only a lower limit is applied. Therefore, maximizing the figure of merit means that the system has been optimized to such an extent that often often unpredictable changes encountered during the various manufacturing steps are unlikely to cause the final product to deviate from specifications.

Description of the invention (16 '" fault-tolerant beta system and good product yield. / According to the Red Book specifications, the CD distance () is between L 5 microns and L 7 microns, with a nominal value of 1.6 microns The nominal length of EFM-coded CD potholes measured from half depth (which traditionally measures all widths and lengths) is 0.3 micrometers per T, where the pothole length spatially represents the instantaneous duration of nT.

The width of a CD hole (,, pw〃) (which is measured again at half depth, as shown in Figure 18), and the writing beam that created this hole The spot diameters are all about 0.5 micrometers, that is, about TP / 3. On the other hand, the read beam is about twice this width, or about 丨 micrometers wide. Because of the use of pure The wavelength of the laser, so that the numerical aperture of the objective lens must be selected so that an unofficial beam source will produce a beam spot of the same diameter, so that no matter what device is used, there will be a hole of the same width, thereby ensuring the obtained pit. Holes can all be read. The spot diameter d is determined by equation d and 0.5 / NA is determined, where λ is the beam wavelength in a vacuum, NA is the numerical aperture, and d is the straight 15 diameter of the obtained spot.

It is speculated that the future of writers and reader beams, smaller potholes, and narrower distances using higher frequencies (ie, shorter divergent wavelengths) Relatively, the application will use similar relative proportions.

I do n’t know how to record the master, the last step in the hybrid disc manufacturing process-18-This paper size applies to China National Standard (CNS) A4 ( 21〇χ 297 mm) A7 1242198 V. Description of the invention (17/10 abruptly) A thermally activated recording layer is spin-coated on the master net copy hybrid disc; a _metal reflective layer is coated on top of this layer; a protective layer is usually applied last. Of course, the recording layer tends to be filled with ROM data Pits (especially shorter running lengths, such as 3T to 5T, see below for details) and the flat part of the intermediary, as well as R 5 prefabricated grooves. The resulting optical recording layer is in ROM pits and R tape prefabricated grooves (after The depth above which the CD-R data crater is burned) depends on many factors, such as the viscosity of the layer before drying, the drying conditions, the rotation speed, and the k-direction shape of the pits and pre-grooves. The final hybrid disc and afterwards The burned hybrid disc must comply with the Orange Book Regulations as a whole, and its ROM area must also meet the Red Book specifications that are included in the Orange 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, device or structure that provides a range of selectively adjustable parameters. Maximizing the value and thereby 15 contributes to the overall flexibility necessary to reliably manufacture discs that meet Red Book and Orange Book specifications in a high-speed manufacturing environment. Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs's Consumer Cooperatives. 20 The Nakagawa Hybrid Disc Patent mentioned above (U.S. Patent No. 5,204, 852 $ Tiger) is based on ROM data pits and R-block photoresist burning. (Paragraph 5 paragraphs 3-20), and proposed to expose the photoresist in the RQM 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, 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 phenomenon of the photoresist will result in the prefabricated groove of the cross section of the first Nakagawa embodiment. However, ‘failed to see Nakagawa ’s proposal of a prefabricated groove with a triangular cross-section such as 25H. In fact, it must reach -19 by the way it reveals. The paper size is applicable to the Chinese National Standard (CNS) A4 regulations (210 X 297 mm) A7 1242198 V. Description of the invention (18) A ^ '---- = The destination material may also be non-f_. The axis may first scatter at the photoresistance, and the exposure cross-section will tend to narrow down from the disc surface, which may result in a generally observed trapezoidal profile. It ’s quite possible b 疋 because at least I realized that making a shallow rectangular cross-section prefabricated groove of the second embodiment 3 = difficulty 'proposed by Nakagawa-the third embodiment (paragraph ^ line 16 to ^ I and 36th)' A first beam exposes the photoresist to (hopefully) create a rectangular cross-section prefabricated groove, and then a second beam locally exposes the entire R-band in order to reduce the effective depth of the prefabricated grooves. I may realize that this type of photoresist double exposure is at most—a very difficult process to control. As in the second example, there is no suggestion as to how this can be achieved.此外 Furthermore, even if Nakagawa or the person skilled in the practice of implementing the content mentioned by him, he really made (but extremely unlikely) a master disc with a rectangular cross section of _ potholes and R π prefabricated grooves to be copied. These masters are also nearly impossible, simply because the net copy hybrid disc >! will be strongly adhered to the mold, and its 15 will present hundreds of thousands of features with vertical sides instead of the usual PR produces the hypotenuse of the trapezoidal cross-section feature seen in the master. Printed on Nakagawa ’s Net Copy Hybrid Disc by the Consumer Property Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the depth of the thermally activated recording layer applied to the prefabricated groove of the r-band must be greater than the pit above the burned ROM depth. This is to ensure that after the spin-coated recording layer spread over the entire disc has been covered with 20, the resulting pits that are selectively burned in the R tape will have the same pits that already exist in ROM I. Effective optical depth. Therefore, Nakagawa suggests that when the heat-activated recording layer has been spin-coated on a net-reproduction hybrid disc, the cross-sectional shape of the corresponding feature will ensure the correct corresponding depth. This is highly unlikely if the pre-groove has a triangular cross-section.

What Yanagimachi said was less instructive than Nakagawa, even if it made sense. Ha (U.S. Patent No. 6,212,158) differs from Yanagimachi mainly in certain parameter values. Specifically, Yanagimachi specifies a ROM pit depth between 250 nm and 350 nm and a ROM channel depth between 30 nm and 170 nm, while jja specifies a depth greater than 170 mm. ROM channel depth in microns. Indeed, the Ha case in line 1 of paragraphs 36-43 points out the difficulty of the Yanagimachi case in creating acceptable hybrid discs that incorporate the recent tremor, depth modulation (r0m) channel. Therefore, Ha uses a very similar concept to modify the Yanagimachi case with different parameter values, and the scope of Ha's patent application is essentially written around the core of the Yanagimachi case. But Ha failed to add anything in the first two cases to promote the manufacture of hybrid discs. To the extent that the Applicant knows all the know-how, nothing has been published (whether alone or in any reasonable combination) that will allow practitioners familiar with the skill to reliably 'reproducibly and efficiently manufacture Orange and Red Book format hybrid discs. This may be (or may not be) because all of the well-known documents in the public relied on the photoresistive method of making a combined disc master, and this method is very difficult as it is impossible. Manufacture a master that can be remanufactured to meet the required specifications. Regardless of the reason, it seems that it is impossible to produce a hybrid disc that meets the specifications based on the conventional technology. Therefore, a method, a device, and the geometries of the pits, flats, and prefabricated grooves in the master mix obtained thereby are needed to efficiently, quickly and reliably produce a replica hybrid that meets all manufacturing specifications CD. -22.

You started and should keep in mind that all the drawings are not based on scale and are only used as illustrations of the features and concepts indicated. Figures 1 and 2 are schematic diagrams of the device used to create a master hybrid disc, which is mainly based on the overall structure. The device is particularly related to the extra components used in the hybrid disc master. In Figures 13-17, this will be mentioned for explanation. Τ 7 Refer to the knowledge, Figure 1 and the '129 patent, to burn the surface data pit and the intermediary flat 3 version of the flattened disc 1 by a spindle motor 3 turns, the motor is controlled by a speed control 5.-the gas laser 7 forms-a human beam 9 of a specific wavelength.

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, a gas laser is used in this embodiment, and the writing beam passes through an external light modulator Η, which is driven by a waveform shaping circuit 31 on line 10 The signal changes the intensity of the writing beam. As mentioned earlier, the optical modulator u may include, for example, an AOM or a faster response EOM (photoelectric modulator). The modulated beam 13 is directed at the master disc 1 and is focused on the active surface 43 via a suitable optical element to form a light spot 15 as described above. These optics preferably include an objective lens 17 and a beam-expanding (i.e., condenser) lens 19 which expands the modulated beam 13 to fill the aperture of the objective lens 17. The numerical aperture of the objective lens is chosen so that the diameter of this spot is approximately 0.5 micrometers (in the case of CD burning), which is equivalent to the wavelength of a typical laser beam used today. These lenses are mounted on the moon frame 21 to make the meridian spot 15 move in a meridional direction relative to the center of the disc 1. This is achieved with a general translation drive system 23, and those skilled in the art will know the details of the system. Alternatively, although Figs. 1 and 2 show that the radial movement of the light spot 15 is controlled by a translation system 23 to move it, and the rotation axis of the master hybrid disc is kept fixed, the reverse is also possible. 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 to the radial parameters of the timing parameters written in the program. In either case, assuming correct alignment, the beam will continue to move relative to the center of rotation of the disc to produce the desired narrow spiral data alignment. In a preferred embodiment, the drive signal of the optical modulator 11 is formed by the waveform shaping circuit 31 'as described in the 129 $ Tiger patent', the purpose of which is to transform the EFM-encoded data pulse wave to the intermediary, and disconnect the sequence space of the unitary space A composite sequence of driving pulse waves separated, the tail region of each pulse wave exhibits a gentle amplitude decay.

Other mildly decaying distributions can also be used in the tail region. It is important to understand that the purpose of any mildly decaying region is to make the amount of heat generated in the reactive dye-polymer layer 43 at the tail end of the formed cavity In these driving pulses, the amplitude of the pulse wave is shown from, to turn on, to write to, and to turn off, and the "basic point of precision"-the rapid decline in the amount of money will cause the heat generation to be more gently reduced. See, in this specification any mildly trailing edge edge decay distribution that contributes to this desired result is interchangeably referred to as one, (ramp). Any such trailing edge slope (the term is broadly defined above) The effect is described in Patent No. 129 as causing the trailing end of the shaped data pits to become tapered. The leading ends of these pits will be tapered because Yu-Renobo before the fast-moving medium felt all the heat accumulation It takes a short time after the leading edge of the leading edge (that is, the light spot 15 starts to act on the active layer 43). The leading end taper can passivate the leading edge of the pulse by increasing the laser power at the leading edge of the pulse as usual. In essence, it is impossible to completely eliminate it. Therefore, after the corresponding driving impulse starts, a gradually widening cone will be formed at the edge of the 4th guide of the pit. Then the amplitude and gentle decay of the tail edge of the field pulse will gradually decrease. A tapering tapering is formed at the tail end of the pothole, reflecting the tapering of the leading end. This is related to the nature of the selective tapering of the tail end of the pothole and the leading end. There is a secret pothole —Horizontal HF detection, as disclosed in Patent No. 129. Of course, the present invention does not rely on the content of the principles described in Patent No. 129, but does not include the principle of Patent No. 129, this application Will also achieve Improved Ran Xianxin believes that the present invention will achieve excellent results when combined with the '129 patent.

Due to the well-known HF and anti-orbital techniques in the single-beam and triple-beam configurations, there is no need to do more of their corresponding devices here It is said that in the later description of Bei's description of Figures 5 to 12, the master hybrid disc will be mentioned, and the various external sign structures, such as riding show. Due to the net duplication of the hybrid disc, Pei came up to read and reproduce this. The corresponding characteristics of the master hybrid discs of the same net copy are the same. It should be understood that the master hybrid discs mentioned in these drawings: Characteristics., ^ It should be understood that because the special choice of recording dyes to be applied to net-reproduction hybrid discs is for the practitioners to choose (probably according to the manufacturer's regulations and instructions for use). Other than the approximation shown in Figures 23 and 24 The corresponding structure in the final hybrid disc. Because only the final hybrid disc and the post-burning hybrid disc must comply with the Orange Book and the Red Book Regulations included in it, it is also necessary to understand that Based on the actually selected materials, devices, and procedures, the mastering and manufacturing processes can be optimized in the manner described below to achieve the results promoted by the present invention.

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 pits in the final hybrid disc The phase depth of the hole is about 3 and / 16. However, this neither optimizes HF detection (requires λ / 4 effective phase depth) nor optimizes counterpoint (requirement; (/ 8 effective phase depth). Figure Figure 6 depicts the modified ROM pits and intermediary flat land in the master hybrid disc obtained by the preferred embodiment of the present invention. It can be seen from the figure that a relatively wide and shallow channel 75 extends along the longitudinal axis of the pit and flat sequence, and the ROM pit sequence is within it. The width of this channel is larger than the ROM pit. The wider channel of the present invention is significantly different from the narrow channel between potholes proposed by Schoofs and the similar narrow channel connecting subsequent potholes proposed by the Nakagawa'Yanagimachi and Ha references mentioned above. The narrowness of these references The intended purpose of the channel seems to be to assist counterpointing, but taking into account the dimensions obtained and based on the other content of these references, it will not actually be possible to achieve this purpose to a significant extent.

V. Description of the invention (32) It is useful (at least much more useful than the conventional technique). Its primary bias = force = the volume of the R belt with a prefabricated groove to apply 4 high-latin materials according to the manufacturer's instructions. ㈣ 明 ㈣ Said the speed test of Wei Shalin. One of the most popular high-speed dyes in CD μΛ today is Ciba Ult-MX. · Specifications and instructions for this particular dye can be obtained from the coffee company, which is a well-known source of CD-R dyes. With the continuous acceleration of the CD-R burning speed ’, it will continue to be used for more complicated deployments especially for higher-speed burning. These know-how have not proposed how to provide such an increased channel volume (typically specified by the manufacturer of such high-speed dyes) and at the same time maintain a good sum in both ROM ▼ and the recorded r tape ... The guiding principle is because its system is on the green Wei # 单 —write human beam to make—the photoresist active layer is exposed; and, the present invention proposes a method for controlling the beam or two beams by independently controlling the beam Width and channel depth are independently controlled, providing a hybrid that meets all of these key needs. In fact, the lateral configuration of all features of the present invention is independently controlled and optimized. It should also be understood that, because of the focus of the present invention, the manufacture of the surface dye-polymer hybrid disc master, it is not difficult to make any desired depth of pits, ROM channels and R-belt precast grooves in the master disc. . This is because the mechanics of this operation, as described above, have a natural tendency to sculpt the beveled recesses of the smooth profile without surface roughness in the master hybrid disc #Manufacture A, and as long as the laser intensity is adjusted appropriately The way is to easily create these recesses of any desired depth in the master disc. This means that the master hybrid disc produced in accordance with the present invention will be far more feature-prone than the rough side PR proposed by the conventional art (for example, the rectangular cross-section feature desired by the method 25 which is not easy to understand).

Description of the invention (33) Therefore, by improving the pp action in the 'hybrid film', the _ channel is increased in width (but the depth is controlled), which will be helped by -CD playback The machine's single beam _11 is seen in the same way as would be seen-wider potholes. In addition, in this single-beam environment, HF copper from hybrid discs can be independently improved by providing optimized narrower and deeper pits 5 holes without considering the contradictory requirements of PP. The PP pair can be optimized independently by providing wide and shallow channels. These narrower pits in the wider and shallower channels provide the added benefit of reducing HF crosstalk between radially adjacent data holders within a hybrid disc. The independent optimization of the hf and PP tests and the reduction of crosstalk are important results facilitated by this embodiment of the invention. Indeed, HF detection from the final hybrid disc can actually be further improved in this way. If the channel 75 is applied to the master hybrid disc by the method described below, the height of the slopes 70a, 70b will be greatly reduced even if they have not completely disappeared, as shown in FIG. 7. This provides a ROM cavity shape in the final hybrid disc, whose 15 effective phase depth can be made closer to the ideal value / 4 than the effective phase depth that can be achieved without the improvements provided by the present invention. Therefore, looking at the final hybrid disc, Xing Detector will see a bottom of the channel corresponding to the bottom of the channel 75 and 77 of the master disc as it originally saw the surface of the final hybrid disc, and will therefore See a practical holeless 20 pit with the correct width and an effective phase depth that provides the desired redundant phase shift. At the same time, the PP detector will see a dual-disc feature with a relatively large expected width in the final hybrid disc. Its effective phase depth is closer to the ideal value of the 7ρ / 2 phase shift. Required a / 8. FIG. 7 shows that the ratio of the height h of the slope 170a, b in the master disc to the depth d of the cavity 50 is much smaller than the ratio in the section 25 shown in FIG. 5 without incorporating any modification of the present invention.

In addition to optimizing the south, (by providing the improved ρρ side of the broad rhyme and simplified path without sacrificing the HF accumulation of several holes of the bandi itself), the slope height reduction achieved by this is also made possible The shallower cracks of the materials that tend to stick to the resulting molds have reduced summers, which helps to accurately reproduce with a master hybrid disc. This is a very important advantage of the present invention in terms of pR-based concepts disclosed in the references cited in this case. 10 / FIG. 7 also sees the small slope 175a, b of the car ball protruding from the surface 68 of the disc at the corresponding edge of the channel 75. But these have only a small effect on pp or volume < testing. ^ The 7F 'slot 75 in Figure 6 can be continued in the flat area where potholes and flat land dominate. Finally, in the final hybrid disc, a corresponding feature with an effective depth of λ / δ is provided. Provides a consistent depth of one of the channels across the entire width and the 15 flat bottom 77 (shown in Figure 8) in a way that promotes reciprocal action between potholes.

The pothole 50 (without slope) (as shown in Figure 9) can slightly increase the width of the channel in the master mixed disc by adjusting the parameters together with the R0M 1242198 A7 B7 formed in the channel. V. Description of the invention ( 35 10 15 Printed by a member of the Intellectual Property Bureau of the Ministry of Economic Affairs and Consumer Cooperatives 20 25 The width of the potholes is correspondingly increased slightly. These parameters include the beam intensity and diameter, which can be adjusted individually or jointly to achieve the following results. The proper selection of the track width can cause the two slopes formed in the new channel of the master hybrid disc to partially overlap with the downward slope of the adjacent slope of the radial adjacent channel that has already been formed. In other words, two adjacent slopes will merge to form a flat-topped area between adjacent channels. This process is repeated as more radially adjacent channels are created, and all radially adjacent sections The flat area of the hole in the master hybrid disc is appropriately selected to cause the slope of the hole formed in the new channel to be minimized or eliminated in a similar manner. If the parameter is adjusted to Make potholes only Slightly narrower than the channels to create these potholes, the slope formed on either side of the new pothole will coincide with the downward slope of the channel. This eliminates the need for These pothole slopes in the hybrid disc itself. The resulting features essentially become a superposition of the features of the channel and the potholes formed in it. Therefore, in reality, they are produced by the master of the hybrid disc The channel caused by these two adjustments in the program becomes potholes, but it is wider and it is no slope at this time. This result has been confirmed by repeated experiments and can be achieved by making parameters for the hybrid disc master. The method of fine tuning is optimized. Figure 9 illustrates another embodiment of the present invention. As mentioned earlier, in the embodiment of the master hybrid disc, there is no ROM channel at all except for the flat area, and The resulting ROMi holes 50 are roughly slopeless with a shallow slope on either side. This helps PP pairing without compromising HF detection in the final hybrid disc. Pairing Improved detection 'because shallower bevels tend to be larger The incident light reflection deviates from the vertical direction. The HF detection is not sacrificed at all, because the effective pit depth is maintained at the traditional 3 λ / 16. The net effect is an overall improvement of the figure of merit.

Description of invention (π 5 10 15 Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs Employee Co-operative Society 20 25 An advantage of the invention. The same The reduction of the slope height is especially due to the careful parameter selection as described in this article, which effectively reduces the slope and reduces the crosstalk between adjacent data holders. This pair is characterized by the narrower distance between current and future applications. This embodiment of the present invention is particularly useful for this purpose. Just as the independent control of the two writing beams (or a single trembling beam) helps to accurately define the lateral structure of ROM pits and channels Control, the use of these two independently controlled beams or a single trembling beam also permits the fabrication of prefabricated grooves in the R-band of the master hybrid disc with any desired lateral configuration and grip. Therefore, the figure of merit in CD hybrid disc mastering applications can be improved by the present invention even without the PP promotion 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 the tick tape prefabricated groove only requires a fixed signal intensity for each written laser beam, not a signal signal modulation for any beam intensity. However, an important feature of the present invention is that the mode of driving the write laser to burn each feature can be selectively programmed in a known way to match the specific sequence of ROM and R bands to be burned and the special characteristics of the specified characteristics. Claim. In particular, since the dual-beam dye-polymer hybrid disc mastering method is used in the preferred embodiment, these from -mode to other-mode: Compared with the conventional technique single-beam PR master The production of the plate is much simpler because there are not most problems inherent to the 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 β-band, as detailed below.疋 For example, the slot 75 can be divided into -38 by dividing the writing beams 13,13 into -38- This paper size applies the Chinese National Standard (CNS) A4 (21 × 297 mm) gutter 1242198 A7 B7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs

Description of the invention (38) Alternative embodiments may involve providing corresponding acceptance to the component by which the channel write beam is generated Channels are controlled to form channels selectively, as described below. 11 is different from FIG. 10 only in that the channel writing beam 103 in FIG. 11 precedes 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 of the 10-way trough > formation is to consistently expel more material from the formed potholes without significantly altering 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 11 currently seems to produce better results for hybrid discs). 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. Regarding 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 (i.e., it will be activated by 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.

Since the main beam 12o (that is, the 'zeroth-order eve beam]) does not experience any deflection in the beam splitter, it will not receive the ATIP modulation in this case. Therefore, the main beam is still Independent ALT modulation will be required and must be passed through the ATP modulator 15o, as in the previous case. The main beam 122 and the output beam 125 are combined in a beam combiner 135, the purpose of which is to calibrate the two Beam for subsequent processing. The beam-riding 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.

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 resulting channel is written into the beam 103 and The input surface of the objective lens is not completely filled, and its M is effectively reduced. The sister beam will not focus into a small core like the data beam 102 filling the objective lens.

As in Figs. 13 and 15, the channel writing beam is focused on the active surface 43 of the disc i. However, because the channel writing beam The smaller NA of the beam has a larger spot size than the main beam 102, thereby creating a channel with a width larger than the data pit. In hybrid CD applications (where the pit width is about 0.5 microns), the groove The spot size of the 10 writing beams on the surface of the disc may be about 1-2 microns. During the burning of the beta band with the pre-groove, the waveform shaping circuit is turned off because the pre-groove is mainly made with a constant-intensity beam Member of the Intellectual Property Bureau of the Ministry of Economic Affairs In the embodiment shown in FIG. 14, a first optical deflector 15Q is inserted in the path of the main beam 122. The purpose is to selectively oscillate the beam 15 to produce it by the action of the input sent through the line 151 to generate A flutter mainly emits a beam 162, which results in a write beam 102. The ATIP input will include a ROM data file and a beta tape prefabricated slot in a manner well known to those familiar with CD-R mastering. All the parameters of the correct tremor of the path are as previously described. A second optical deflector 155, which is also controlled by the same ATIp input signal (through line 156), similarly introduces the desired tremor into beam 20 124. This will produce an output Beam 161. After passing through the inverted telescope 130, this beam will obtain a secondary outgoing beam ι63, and then a channel writing beam 103. Preferably, the light deflectors 15 and 155 are both A 〇Ds. 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 light deflectors 150,155 comes from a single source, as previously suggested. __________- 44 -_____ a copy Zhang scale applicable Chinese National Standard (CNS) A4 size (210 X 297 mm) (43)

Those skilled in the art based on the present invention will understand that the intensity of the writing beam in a channel can be changed so that the depth of the obtained channel is correspondingly changed. This change in beam intensity can be easily achieved, for example, by selectively controlling the intensity level of the output beam 161 directed at the inverted telescope 130 (the secondary exit beam 163 is emitted from this). This series 5 selects the laser power and intensity ratio input to the beam splitter. In any case, the final intensity of the channel writing beam can be easily selected to provide an effect within the active layer, ranging from the creation of a full-depth channel as described previously to only slope removal measures. The latter will require a beam intensity sufficient to produce a heating level in the moving active layer 43 which is only slightly above its thermal threshold, while the former will require a suitably high intensity. Such adjustments to produce any desired results would be within the capabilities of the average practitioner based on the present invention. Those who are familiar with dye-polymer optics will remember that the channel created by the channel writing beam will tend to have an arc-shaped base (viewed on the cross section transverse to the channel axis), all other aspects the same. This is because, like the writing beam in the main pit I5 hole, the intensity cross section of the roughly circular beam will be approximately along its diameter-Airy Disc distribution, with the maximum intensity closest to its center. However, in a clever use, 'it may be expected to have a flatter bottom channel, as shown in Figure 8. In particular, by providing a consistent and / 8 phase depth along the base of the channel in the final hybrid disc, it may improve alignment. Executive role. 20 8115 The result of the relative movement of the channel writing beam in the channel writing beam and the hole writing beam along the track is trembling (that is, the axis transverse to the axis of the pit is rapidly vibrated). Means to produce this relatively flat bottomed channel. It should be noted that FIG. 15 is directed to the configuration shown in FIG. The correlation shown is the use of an external light 5 light gas laser. It is hereby recognized that practitioners 25 who are familiar with this technique can easily apply the key points shown in FIG. 2 to the device shown in FIG. 2 (that is, used in the embodiments shown in FIGS. 14-45-1242198 A7 B7 V.

In the CD mastering mode, release the ATIP signal of 5 via line 151 25f because the CD mastering does not need to generate chatter.

A flat-bottom channel can be achieved by a diffraction grating (Or other general diffractive 5 pieces such as a phase grating) instead of the inverted telescope shown in Figure 13-15. This grating transforms the channel writing beam 124 from the beam splitter 100 into Two images staggered from each other, these two images together constitute a single widened laser beam irradiated on the light-activated surface. This embodiment is depicted in FIG. 16, which is based on FIG. 14 (diode laser Example) 10 1 Basic 'and where the relative focus position of the beam Largely separated for clarity. This diode laser embodiment was chosen to simplify its expression, but it should be understood that a gas #shooting supplement with an external light modulation H may be used as a basis for FIG. 16 ' Because the nature of the beam source is not important to the present invention.

The purpose is to divide the incident light beam into a pair of outgoing beams 201a, b slightly offset from each other. This artist can easily replace it with an alternative optical device to achieve this goal. As shown in detail in Fig. 16, since each of the emitted beams has a transverse load surface of approximate Nans intensity, a small amount of mutual displacement will cause a joint beam, Its 20-degree intensity distribution (in the cross-section along the displacement drawing line) is approximately rectangular, as shown in the figure.

The purpose is also similar: to transform the beam 122 into- A radial direction (ie, the up-down direction as shown in FIG. 17) is shifted relative to the output beam of the system jitter.

Description of the invention (47 5 10 15 Printed by the Consumer Property Cooperative of the Intellectual Property Bureau, produced by 20 25 31, the input of this waveform shaping circuit will simultaneously determine the instantaneous intensity of the beam 270 written on the active surface 43 in the disc 1 holding, 'beam rotation ^' And the radial position of the focused spot. Therefore, by generating a suitable input signal to the waveform shaping circuit (which is within the ability of ordinary practitioners based on the present invention to refer to the cited content and the literature), the disk can be rotated The active surface of the film spirally burns extremely complex patterns. If a mastering disc is made from the master disc made in this way, it can be turned into thousands of reproductions. For example, this technique may be used purely to form more precise ROM pits for a master hybrid disc. The beam is narrowly focused into a very small spot through the selection of appropriate optical parameters and writing beam wavelength. When the disc is rotated, the tiny light spot appears very quickly in the-range (in the-radial direction relative to the disc), which is equivalent to the width of each hole in the data holder to be written. This jitter range can be accurately changed as the desired width of each pit along its length changes during writing. Between the potholes in the channel, the light modulator extinguishes the beam until the next pothole starts. In the "turn-to-polymer" ship towel, the pits obtained by hot-smearing have appropriate structures in plan and section views. Because of the fast and precise controlled shaking of a relatively small beam, the resulting pothole can be navigable—it is more accurately formed by simply writing a human beam according to financial difficulties. In the second real money, the road can be formed in one of the continuous channels of the master mixed disc. In this case, a second tremor signal is superimposed on the pit-forming tremor signal (that is, summed with the latter), where the sequence of pits and flat ground will reside in the channels on the disc. Channel Depth = Determined by the increase in beam intensity corresponding to the way the property is formed (usually seldom generated-only increased heat inflow slightly above the thermal threshold of mobile media), and this secondary tremor should be widened.

And Xing detection. … In the R band of the master hybrid disc, the continuous prefabrication groove is created by providing a single trembling signal with a predetermined trembling range and appropriate intensity, and the Ατιρ facial motion number 10 is superimposed on this trembling signal. As mentioned earlier, this mode is activated by the stylized components, which is within the ability of the skilled person. In all of these examples and mode towels, the tremor and beam amplitude can be controlled by conventional components to produce almost any desired geometry of the cavity and R-belt 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 literature to improve the pR master making technology by accurately controlling the two-dimensional range of the photoresist exposure 2. 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. 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 diodes. 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. However, 25 Xianxin has hereby given a full explanation to enable those skilled in the art to implement all of the above -50- This paper size applies the Chinese National Standard (CNS) A4 specification (21〇χ 297 mm) 1242198 A 7 B7 V.

Lice The design choices of lasers or diode lasers, among which at least, each Ding Wan-style laser beam is separated from each-beam can therefore, for example, be implemented as shown in Figure 13 For example, the base beam is selectively focused on the data track—different from the gate expansion rf ', so that the data writing beam 102 and the channel writing beam ⑽ say: the writing time difference. This can lead to such The beam is caused by the heavy beam # 12 shown in FIG. 10-the beam is ahead of the other beam. If the -field beam is used as the writing beam source, as shown in Fig. 14, for example, then at least one is not provided. A bar for coordinated independent modulation lasers or an external modulator for each laser It will be more difficult to achieve this goal. It has been clarified again that the objective of the present invention is at least to some extent by removing (or reducing V)-the way in which the slope generally occurs in the dye-polymer method Except for U.S. Patent Nos. 5,627 (Cubi1; et al.)

The literature on the slopes formed during the thermal programming process is quite scarce.

Description of the invention (M 10 15 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 20 25 Printed by 25 25 than the expected result even if converted to the field of mixed discs The technology that can significantly reduce the slope height ratio is necessary to achieve an ideal result. Of course, the optical data recording by the PR method usually does not show the slope at all, because this method is not a heat treatment process and is three-dimensional. Material is not punched out by this method when the mark is formed. Although heat treatment procedures (such as the dye-polymer method) are inherently susceptible to slope formation (which is mitigated by the aforementioned embodiments of the present invention), these procedures are different from the PR method, The fact that as long as it is well controlled, it is easy to produce smooth surface pits with continuous slopes. Although I have observed that the polymer adhesive structure used to form the master disc dye-polymer recording layer will Regarding the optical data produced by CD and j) vj) master, the degree of the slope generated in the master production process has a profound effect, my It has not been observed that these steps are particularly valuable in the production of hybrid disc masters. In any case, you must refer to the mother's case for a full discussion of this issue. Of course, the writing method and the reading beam used for the hybrid disc #master in the touch method method are derived from sources other than lasers. 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, and some of them may be left to 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 within the capabilities of those skilled in coping with these alternative A sources, by means of inevitable and modified devices and / or methods Performing its implementation also constitutes equivalents that do not exceed the scope of the claimed invention. As is known in the CD manufacturing technology and briefly mentioned before, the master is applied by applying a very thin metal coating (sputtering or vapor deposition) to the master and then growing the coating with DC nickel electricity.

The Haixiang sheet drawing constitutes a mold for obtaining a complex sheet (in this case, a net copy hybrid type) by high temperature and high injection molding. After that, suitable dyes, such as those mentioned in the CD-R literature, are spin-coated in a conventional manner and cured. As in the case of osmium manufacturing, the dye layer is then sprayed and then a layer is applied to produce a final hybrid disc. Dye manufacturers such as Ciba (see above) often include very detailed instructions in their product manuals and application notes, such as how the manufacturer's specific 10 wood should be used in the coating process. Practitioners refer to these dye manufacturer's methodological instructions for more information on spin coating and related issues. The preferred size ranges in the net copy hybrid and final hybrid discs made according to Benjamin are listed below with reference to FIGS. 19-23.

The reason for this significant difference is due to The ROM channel where the pothole is located is almost the same width or even slightly wider (as shown in Figure 25, the σ xuan diagram generally shows the data shown in Table 3). The pothole starting level 324 effective leveling level 334 is essentially Are overlapping.

5 IX 20 23 25 Corpse ', &quot;, Xiao <Mai Tanluo Luo is beyond the scope of previous research, and I have recently discovered that a master with a leg slot and ROM pit size as shown in the following three examples The overall performance and figure of merit of the final hybrid CDs copied from the hybrid discs were not substantially impaired. These data are generated in accordance with the manufacturer ’s instructions for use of ciba Ultragreen MX dyes in addition to the content disclosed in Application No. 027, and are listed in Table 3 below. It should be understood that these data are measured from the model. The characteristic size of discs copied from such production dies may be about 5% less. Depth is calculated from the effective level (shown as 334 in Fig. 25). Width is measured from half depth and is also shown in Figure —. These pothole data are values obtained from potholes with longer run lengths (e.g., about 9-11T). The shorter pits are expected to exhibit smaller pit widths. Referring to Table 3 below, it should be understood that in this case and most other cases, the dimensions of the R channel and the Li channel are essentially the same, because in fact, the R channel and the ROM channel are usually -57- The standard applies to China National Standard (CNS) A4 specification (210 X 297 public love) 1242198 A7 ___________ B7 is the same channel.

In particular, although the data in 5 does not indicate 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 11% of the ROM channel width. These data are taken from a hybrid CD disc with a 1.6-micron pitch and a total capacity of 65 million bytes. In the case where the pitch is 1.5 micrometers (this is necessary for a combined disc capacity of 700 million bytes), if the ROM pit is wider than the ROM slot, 10 crosstalk may occur. problem. In any case, these data indeed prove that by adjusting the gauge, it is possible to have ROM pits with a width as high as about 10% of the width of the channel in which they are located. This situation is depicted in Figure 2 and Figure 24b, which are a simplified scan of the ROM channel of similar size (Figure 24a) and a simplified scan of the ROM cavity (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 ice in the pothole increases due to the channel in which it is located. . Here, the pothole 334 in FIG. 25 is taken as an example. Therefore, the above-mentioned recent research has shown that by using the materials and techniques disclosed in Application No. 27, the potholes can indeed be slightly wider than the channels without affecting the overall performance and merit of the hybrid CDs obtained by replication. 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 bandit pit ratio is -58-, this paper size applies the Chinese National Standard (CNS) A4 specification (21 × 297 mm) 1242198 A7 V. Description of the invention (57) 5 10 15 Employees of the Intellectual Property Bureau, Ministry of Economic Affairs Cooperative printed 20 25 It ’s a narrow channel, which presents less crosstalk problems and provides better overall results for most motorcycles, especially those with a smaller distance will be better than Likeng The hole is better than the case where the bandit is the same width or wider. FIG. 23b depicts _ _ _ which is substantially narrower than the _channel_ where it is located; for comparison with the configuration shown in FIG. 25. Such a technical towel is known. The GD_RW test is based on the reflectivity of two-phase (ie, crystalline or amorphous) materials with binary data values, which is based on the measurement of 'the binary, zero'. "One" which represents one of the two phases and is binary represents another-phase. Therefore, the depth of the pits in the CD-RW hybrid disc is relatively small 'must be much smaller than 250 nm, and perhaps even smaller than 90 μm or less. The application of a very thin future dysprosium dye layer on the outer surface may result in a burn-in pit that provides sufficient HF and PP response when read from the second side in a conventional CD-R hybrid disc in a conventional manner. For these thin dye layers, the required depth of ROM i in the substrate must also be much less than 2 such as nanometers. It is found that the better relationship between the corresponding characteristic Wei degree is in the range of 30% to 80% before and after the dye coating, and it is best to range from 5 ()% to 鄕. Father's Day is 30% to 80% of DRGrwe; and DrOMGD is preferably 30% to 80% of 仏 〇 心 _, of which the range of 50% to 70% is the best. However, although recent research has shown that ^ "can be equal to or even slightly greater than WRQMGr_, we have found and continue to believe that the optimal coordination of the contradictory requirements of Xing and pp detection occurs in W ™ Gr_e-WPlt. We have also observed DRGMGr_ must be made to provide a sufficient counter-signal and reliable ATIP reply, so that it does not sacrifice reliable high-speed replication capabilities due to deep pits. Because there are so many parameters for each manufacturing system and each system There are large differences between them, and it is not possible to specify individual parameters for some of these parameters other than the above-mentioned classification guidelines.

Description of the invention (58) ~ ^-Values [as known and understood by those who have experienced in this category, each The system must be optimized to provide the highest possible figure of merit, especially in the case of hybrid disc mastering and manufacturing. Net reproductions can be employed to meet the above requirements and are optimized in advance 5 to the extent that they have not continued to the spin-coating stage. If the above criteria are not met, one or more of the available parameters may be adjusted appropriately during the mastering phase or any other step throughout the upstream manufacturing chain that is considered to result in unacceptable results. Generally speaking, first adjust the mastering parameters, as this is just a matter of changing one or more adjustable inputs. 10 This parameter adjustment operation is inherent to the feedback optimization technology commonly used in CD manufacturing, and includes: (1) making a master; (2) performing in a complete U-line from start to finish Duplicate, this manufacturing line is best to be in the same room; (3) Analyze the duplicates and note the manner and extent that the duplicates do not meet the applicable specifications or requirements; (4) Readjust the master production parameters; (5) Generate Subsequent copies are analyzed for 15 and (6) this procedure is repeated until a copy with the desired characteristics is consistently obtained. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Ultimately, the final hybrid disc and the post-burning hybrid disc must meet the Orange Book specifications, and the corresponding ROM area must meet the Red Book specifications included in the Orange Book specifications. This requires further optimization along the route described above to meet some specifications, and maximizing the merit to ensure that these regulations will continue to be met. Every 20 manufacturing line variables may need to be adjusted to achieve the desired result. For example, one of the manufacturing variables commonly 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. Radial reduction in pressure may cause ROM pits in net-replicated hybrid discs to become shallower on the outer side of the reciprocating disc. The aforementioned U.S. Patent No. 25 5'6〇8,712 should be applied in a manner similar to the application of the slope trimming function mentioned above.-60-This paper is applicable in China Standard (CNS) A4 Specification (X (Read 297) 1242198 A7 B7 V. Description of Invention (59) Pay this question. This just shows that there are different optimization challenges for 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 the improvements of the present invention 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-replicated hybrid disc or possibly other medium 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. For example, printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. It can also be applied to the manufacture of CD-RW hybrid discs or MO discs. C]) — The only difference between the RW hybrid disc format and the CD-R (or DVD-R) hybrid disc format lies in the choice of recording layers applied to the net copy hybrid disc. In the case of ⑶, the material deposited on the net copy hybrid disc by vacuum will be a homogeneous phase change material, and the mark of the bandit may be a data pit, which is the same as the case of CD (or excitation) hybrid picking. In the M0 case, the 'vacuum-deposited substance will be a conventional material, and its magnetic orientation can be selectively reversed by a thermal component acting in concert with an external magnetic field. These materials and their applications and uses are well known to those skilled in the art, who will immediately understand that the vertical dimensions of features on master hybrid discs and net replicas are not necessarily the same as in the hybrid CD case. The characteristics of _ big size can reach the appropriate phase depth in the final hybrid disc. Likewise, the invention is not limited to the use of women's discs. Its content can also be applied to any reproducible structure that has weaving performance information and financial records that selectively record data on the final reproducible structure.
