1358062 17312pif_doc IX. Description of the invention: [Technical field of invention], this r:=r; a method and a device for recording and reproducing (4) in a county, and a storage medium to remove interference (10) between symbols to improve ❻ 【Prior Art】 Recording of the material---------------------------------------------------- Resolution == In other words, because the light emitted from the light source is not very common, it is a very common record mark. Therefore, such data can no longer be reproduced, and can be regenerated - a record that exceeds such resolution. ^ Super-resolution phenomenon. Nowadays, it is found that the phenomenon of super-resolution is the history of the boat and the super-analysis of the current (four) research is in progress, because the recycling of the mark exceeds the resolution limit of the record mark, the super solution], the storage medium can be clearly matched High Density and Large Storage = 6 1358062 17312pif.doc To perform, but to record irregular intervals (in other words, mark position detection method) with the same length of mark, or to record irregular intervals with Different length markers (in other words, marker length detection methods) are used. In particular, in the CD or DVD, the marks of various lengths between the range of 玎 and 11T (where Τ is not a timing frequency) are combined, but none of the above-mentioned super-resolution techniques can be successfully reproduced. The composite signal, because the signal reflected by the optical recording medium contains not only the signal reflected by the light spot area whose optical characteristic is changed, but also the signal reflected by the peripheral area whose optical characteristic changes, if there is no signal from the surrounding area, the effective light The size of the dots is significantly reduced, so the composite signal β can be reproduced. However, in the above-described super-resolution technique, the difference between the region where the optical characteristics are changed and the peripheral region is used, and since the difference is small 'reflected by the peripheral region The signal becomes an obstacle $ for the reduction of the spot size. When a series of marks are reproduced, the result in the inter-symbol interference (ISI) occurs, so that the composite signal with high resolution cannot be reproduced. Fig. 2A shows a recording pattern of a mark recorded on the information storage medium, and Fig. 2B shows an Rp signal corresponding to the reproduction mark of the record of Fig. 2A. When the wavelength of a laser beam is

At 405nm, NA 曰疋0.85, and its resolution will be close to 75nm, the recording pattern according to the mark combination will be close to 75nm, which will be smaller than the resolution, the mark close to 3〇〇nm will be larger than the resolution, and two There is space between the marks. In the reproduced signal shown in Fig. 2B, when the mark of 3〇〇nm length or the space exists near the light 4, the mark of 75nm length will be affected by the long mark and the thermal method π The detection of a 75 nm long mark with a 75 nm 1358062 17312 pif. doc unit splits a beam emitted from a single source into the first and second beams. In the step of separating the light beam emitted from a single light source, one of the plurality of diffracted beams generated by the diffraction unit +j;th order of the diffracted beam can be used as the first beam, and __kth The graded diffracted beam is used as the second beam; or a diffracted beam of one of the plurality of diffracted beams generated by the diffractive beam may be used as the first beam, and a +kth order is used. The beam is used as the second beam. In other objects of the invention, the illumination operation may comprise separate packages

The first light source and the second light beam are emitted from the individual light sources including the first light source and the second light source.

According to another object of the present invention, there is provided a method for reproducing data recorded in a super-resolution memory storage medium, wherein the value of the mark is smaller than the resolution of the incident light beam, the method comprising: illuminating the first energy having the super-resolution energy The light beam enters the information storage medium; and with a specific time delay, illuminates a plurality of second light beams having no super-resolution energy into the information storage medium that has been thinned by the first light beam; and according to the first light beam two signals and The second beam of the second regenerative signal is measured by a maximum of 5^. According to another aspect of the present invention, the detecting operation includes obtaining a difference signal between the signal and the second reproduced signal. According to other objects of the present invention, the intrusion operation can be performed in the second regenerative duty (4), or the second step of the regenerative operation includes compensation for the specific time delay. The jitter or bit error rate (bER) of the signal will be minimal. or = Detect = 1358062 17312pif.doc The first to third dielectric layers 320, 340, and 360 control the optical and/or thermal characteristics of the super-resolution information storage medium, The cover layer 37 〇 covers the structural layer on the substrate 310, including the recording layer 33〇 and the super-resolution layer =0. Here, the first to third dielectric layers 32, 34, 36, and 36 are not necessary components of the super-resolution information storage medium, of course, even if these structural layers are not formed in the super-resolution information casting medium. Information can still be regenerated. ° " The first to second dielectric layers 320, 340, and 360 are suitably, but not necessarily, comprised of a material selected from the group consisting of a halide, a nitride, a carbide, a sulfide, and a fluoride. In other words, the first to third dielectric layers 32A, '340, and 360 are more suitable but not necessarily selected from the group consisting of yttrium oxide (Si〇x), oxidized town (MgOx), and sputum (Αι〇χ). ), titanium oxide (TiQx), vanadium oxide (ν〇χ), chromium oxide (CrOx), nickel oxide (Ni〇x), yttrium oxide (Zr〇x), oxygen (GeOx), zinc oxide (ΖηΟχ) , nitriding cerium (siNx), nitriding (Α1ΝΧ), titanium nitride (TiNx), nitriding (ZrNx), gasification error (GeNx), carbon carbide sic, zinc sulfide (ZnS), vulcanization A compound of zinc-niobium dioxide (ZnS_Si〇2), and magnesium fluoride (MgF2). The recording layer 330 has a structure in which a recording mark recorded by an incident beam of a specific recording energy level has a right-angled section or a section substantially the same as a right-angled shape, wherein the recording mark (m) includes a value not larger than Marking of the resolution of the optical head used for regeneration. In order to repeat the reproduction data using the super-resolution phenomenon, the chemical reaction temperature Tw of the reaction layer 330 is higher than the temperature Tr of the super-resolution reproduction layer 350 in which the super-resolution phenomenon occurs. 13 1358062 17312pif.doc Therefore, in order to form the recording mark (m), the recording layer 330 must have a single layer structure having a mixture of two or more materials (such as materials A and B shown in FIG. 3), which is specific There are different physical properties at temperature and will react chemically.

For example, the recording layer 330 exists in a pattern in which a material A and B are mixed before data recording, that is, before a material A and B chemically react, when a recording beam having a specific energy state is irradiated to the recording layer. In 330, the chemical reaction between materials A and B occurs in a region where one spot of the recording layer 33〇 falls, and the state of the recording layer is changed from the material person 6 to the mixture of materials A and B. The characteristic compound A+B 'Compound A+B forms a recording mark (m) 'which has a different reflectance than the recorded mark in other areas. Examples of the material A include tungsten (W), and examples of the material b include bismuth (Si) 'based on the actual condition' using Ge-Sb-Te as a material of the super-resolution reproduction layer, 'super-resolution phenomenon during regeneration It will happen near the camera at 350 degrees' and the record must be made at the regeneration temperature, in other words,

A W-Si alloy has a reaction temperature close to 6 degrees Celsius and is not affected by regenerative energy. When the W and Si are selected, the 'recording layer 330 is more suitable, but not necessary' is a mixture of two materials such as the number of atoms of W and the atomic ratio of Si to 1 to 2'. In this case, The compound is formed by a chemical reaction occurring at a specific region of the recording layer 330 that illuminates the recording energy beam. The ratio of W to Si atoms mentioned above, that is, 1:2 is only used as a demonstration 'but not Limit the ratio here. 14 1358062 17312pif.d〇c Main phase change material composition. Therefore, the super-resolution reproduction layer 350 generates an area of super-resolution, because the phase change at a specific temperature, where temperature distribution or optical specific changes occur in the light-off areas, thereby allowing recording The information in the recording mark (m) type whose value is smaller than the resolution is restored. As noted above, a region of super-resolution that produces a change in temperature distribution or optical properties with a reconstructed beam will result in regions of the reconstructed spot that may be located in the center portion of the spot. • The above information storage medium is only used to illustrate the phenomenon of super-resolution, and in addition, according to the reproduction method provided by the present invention, any form of information storage medium exhibiting a super-resolution phenomenon can be employed. A method of reproducing information storage media data will be described below in accordance with the purpose of the present invention. In the data reproducing method of the information storage medium provided by the present invention, the relatively high energy first beam B1 and the relatively low energy second beam B2 are irradiated onto the information storage medium, as shown in FIG. The recording mark will be recorded along the track (T) of the information storage medium, and the first beam and the second beam B2 will illuminate at different positions on the same track. The time-first-light east B1 and the second light beam B2 may be formed by separating a light beam emitted by the light source by using a beam splitter, or by using two light sources to provide radiation beams of different magnitudes. The separator can be a grating element or a diffractive element such as a h〇丨〇gram. The first beam B1 has regenerative energy that causes the super-resolution phenomenon to occur, which is called super-resolution energy, and the regenerative energy of the second beam B2 does not ^ 1358062 17312pif.d〇c the super-resolution phenomenon is called Without the super-resolution energy, the first light East B1 and the second light beam B2 can be simultaneously illuminated. In the region irradiated by the first light beam B1, as shown in FIG. 5A, a change in temperature distribution or optical characteristics occurs in the pupil region, thereby forming a super-resolution region where super-resolution phenomenon occurs, Super resolution

In the peripheral region of the degree region, the phenomenon of super-resolution does not occur, and as shown in Fig. 5B, the super-resolution phenomenon does not occur in the region irradiated by the second filament B2. The wavelength of the first beam B1 is λ, and when the numerical aperture is NA1, the decomposition of the beam B1 is ^λ/(4*ΝΑ1), and when the single-light source is used to obtain the first and second beams B1 and B2, The wavelength of the two beams B2 is the same as that of the first beam B1, that is, nine, and when the numerical aperture is NA2, the resolution of the second beam B2 is λ/(4*ΝΑ2), and the numerical aperture of the beam is defined as the focal length of the objective lens. Divided by the diameter of the beam. One object of the present invention is that, according to one concept, only the signal of the super-resolution region reflected from the spot can be obtained by deducting the signal reflected by the peripheral region from the signal reflected from the entire region of the spot. FIG. 6A illustrates a first reproduction signal obtained by irradiating a light beam of super-resolution energy to a recording mark in the recording pattern shown in FIG. 2A by using the data reproduction method provided by the present invention; FIG. 66 illustrates an embodiment of the present invention. The data reproduction method is provided by irradiating a beam having no super-resolution energy to the second reproduction signal obtained by recording the mark in the recording pattern shown in FIG. 2A; FIG. 6C is the first reproduction signal and the second reproduction signal. A difference signal between. — 17 1358062 17312pif.doc In other words, the first regenerative signal in FIG. 6A has a super-resolution phenomenon, in which the mark recorded in the pattern of FIG. 2A is reproduced; and the second reproduced signal in FIG. 6B does not. There is a phenomenon of super-resolution, in which the marks recorded in the pattern of Fig. 2A are reproduced. The time delay of the first reproduced signal and the second reproduced signal is compensated and operated by a difference signal to obtain a difference signal between the first reproduced signal and the second reproduced signal shown in FIG. 6C. Then, the signal component reflected by the peripheral area of the spot is excluded from the difference signal, and only the signal component from the super-resolution area remains in the difference signal, thereby overcoming the ISI problem caused by the surrounding area. Referring to FIG. 6C, a 75 nm mark having a value smaller than the resolution and having a void therein can be accurately reproduced at the portions A, B, C, D, E, and F at the portions A, B, C, D, E, and F. The level of the signal will be uniform regardless of the number of marks and gaps. In addition, even when the 300 nm mark and the void are adjacent to the 75 nm mark and the void, the signal state of the 300 nm mark adjacent to the 75 nm mark is continuous with those of the other 300 nm mark. Furthermore, with respect to the 300 nm mark, the plateau area at the high and low places is smaller than the entire spot size, and it is recommended to reduce the effective beam for reproduction to a size corresponding to the actual spot size. At this time, although the difference signal between the first reproduced signal and the second reproduced signal has been described and illustrated by the embodiment, the change of the operating technique can also be used. 7A, 7B and 7C show the reproduction results of the data recorded in the random recording pattern by the reproduced signal provided by the present invention. FIG. 7A illustrates a first-regeneration signal obtained by using the data re-master method provided by the present invention using the first energy light east random reproduction record mark 18 1358062 17312pif.doc; and 7B introducing the second energy using the data reproduction method provided by the present invention. The second reproduced signal obtained by randomly reproducing the recording mark of the light beam; and FIG. 7C is a difference signal between the first and second reproduced signals shown in FIGS. 7 and 7B. Because the figure is not fixed from the state of the first and second regenerative Wei, the memorization cannot accurately reproduce 'Although the first and second regenerative ages are divided, the other side, 'the 7C The difference signal has a fixed state, so if it is bad

The alien signal is divided into the 敎 state, and the _ record can be reproduced. _ Figure 8 shows the visual pattern obtained by the difference signal in Figure 7C, showing that the regenerative signal is good, that is to say, the information provided by the present invention can be recorded in the super-ride information storage medium. Randomly record the data in the pattern. In the data regeneration method provided by the present invention, the beam of super-resolution energy and the beam without super-riding energy will be used for a predetermined time delay, according to the first degree of the county--regeneration and The time delay between the second regenerative signal of the beam of 1 is compensated and operated with the ideal technique. In such a manner, (8) generated in the peripheral region of the super-resolution region in the reproduction spot + can be avoided, whereby the reproduced signal characteristic can be improved with a simple method. The present invention can be carried out. Fig. 9A shows a data reproducing method of a data reproducing apparatus 9A. The data re-master device 9G0 includes an optical pickup salt, a recording/reproducing signal processing H, and a health controller (4); more particularly, the optical reading head 9U) includes a _yang 911, which is a beam of light. 19 1358062 173l2pif.doc A diffraction unit 912 is used to diffract the light beam emitted from the light source 911, a collimating lens 913 is used to align the light beam passing through the diffraction unit 912, and a beam splitter 914 is used to change the incident light beam. The transmission path, and an objective lens 915, are used to focus the beam passing through the beam splitter 914 onto the information storage medium 300. The light beam emitted by the light source 911 is separated into a first light beam and a second light beam by the diffraction unit 912, and the energy of the first light beam and the energy of the second light beam can be adjusted by the diffraction pattern of the diffraction unit 912 to be adjusted. The unit 912 can be a grating element or a hologram. The first beam and the second beam reflected from the information storage medium 300 are reflected by the beam splitter 914 and are connected by the photodetector 916. The first beam and the second beam received by the photodetector 916 are recorded/regenerated. The signal processor 92 is converted into an electronic signal and output as a reproduced signal. The recording/reproducing signal processor 920 can have an amplifier 921 for amplifying the first beam signal converted by the detector 916 as a spot, and a buffer 922 for compensating the photodetector 916 for the spot conversion. A time delay of the two beam signals, the reproduced signal of the first beam and the reproduced signal of the second beam are converted by the operating unit 923, and then rotated through a channel 1 (αα) as a radio frequency (RF) signal, and transmitted through An outbound as a reduction of the county. (^3 will explain the diffraction unit 912 in detail. The second beam with the super-resolution energy element and the energy without super-resolution energy needs to satisfy the condition of the aberration amount in addition to the energy bar t, in other words, The amount of aberration of the first and second beams will be substantially consistent. When the amount of aberration between the first beam and the second beam/beam 20 1358062 17312pif.doc is different, the light formed on the information storage medium through the first beam The shape of the dots may be different from the shape of the spot formed on the information storage medium by the second light beam, and the different spot shapes formed by the first and second beams may make it difficult, but not incapable of achieving the object of the present invention. In order to satisfy the conditions of the energy conditions and the amount of difference for the first beam and the second beam, a grooved light tree unit is used in the diffraction unit 912 of the present invention. Fig. 9B illustrates the grooved grating unit 912 provided by the present invention. When the light beam 951 emitted by the light source 911 is incident on the grooved grating unit 912 of FIG. 9B, a plurality of winding beams, that is, a diffraction beam 952 of the 〇th order, a diffraction beam 953 of the +lst order, - Ist grade diffracted light The 954, and the 2nd-order diffracted beam to the N-level diffracted beam (not shown) will be emitted by the trough-like grating unit 912 'where n theoretically represents an infinite integer. +lst-level diffraction The amount of aberration of the diffracted beam 954 of the beam 953 and the -Ist stage is almost identical, and it is easy for those skilled in the art to apply the trough-like grating unit 912 to the present invention so that the diffracted beam 953 of the +ist class has high energy. The -Ist-level diffracted beam 954 has a lower energy relative to the +lst-order diffracted beam 953, or the +lst-order diffracted beam 953 has low energy and the -Ist-order diffracted beam 954 is relative to + The 1'-order diffracted beam 953 has a higher energy, and the energy of the 0-order diffracted beam 952 is too weak to be ignored. The data reproducing device 900 in FIG. 9A includes a diffraction unit to generate a first beam. The second light beam, which may also include a separate light source, that is, the first light source 941a to emit a super-resolution energy beam, that is, the first light 21 1358062 17312pif.doc ί: and a second light source 941b to emit no super-resolution energy The beam is the second beam, as shown in Figure 10. In FIG. 1A, the first light source 941a and the first light source 941b may be placed in an optical module 941, or the first light source and the second light source may be separately provided and set differently except for forming the optical module. Positionally, when the first light source and the second light source are respectively provided in such a manner, it is not necessary to additionally provide a diffraction unit to generate the first and second light beams. In Fig. 10, the same reference numerals are used to indicate The units shown in Fig. 9 have the same function, and will be described in detail below. On the one hand, the photodetector 942 includes a first photodetector 942a for receiving radiation from the first source 941a and self-information. The first light beam reflected by the storage medium 300 and the second light detector 942b are connected to the second light beam radiated by the second light source 941b and reflected from the information storage medium 3, according to the first light beam The time delay between the reproduced signal and the second reproduced signal according to the second beam is compensated by the compensator 922 and converted by the operating unit 923 to generate an RF having excellent signal characteristics without ι§ι Signal. As described above, when the first light source and the second light source are separately provided, whether the first light source or the second light source can be used as a light source for data recording, the first light source and the second light source can be combined with such an optical reading. The headers are compatible for use with information storage media having different formats. To this end, the two beams of the present invention, that is, the first beam having the super-resolution energy and the second beam having no super-resolution energy, are irradiated onto the super-resolution information storage medium that has been mentioned. However, in the implementation of this issue 22 1358062 17312pif.doc ^, can be (four) - miscellaneous materials or a number of students with no super-resolution = a light county production of this 福 个 合 合 而 而 而 而Super-resolution energy is two complex numbers; ^ bundle s and one with super-riding degree can illuminate the super-resolution information storage medium $ bundle break = .,, 'super-resolution multiple beams will have super-resolution metric = After illuminating the super-resolution information storage media, use:

Those skilled in the art can use the present invention to obtain the final RF signal in the equation.

Fig. 11 is a ". private map showing a data reproducing method performed by the data reproducing bud 900 of Fig. 9A or 1 。. Please refer to Fig. n, first in the operation ^, 1100 'optical reading head 91 〇 or 94 〇 The first light beam having the super-resolution energy is irradiated onto the information storage medium 300. Next, in operation step 111, the optical pickup 91 〇 or 94 〇 is irradiated with a specific time delay to illuminate the energy without super-resolution energy. The second light beam is incident on the information storage medium 300 illuminated by the first light. The illumination of the second light beam having a specific time delay does not mean that the optical pickup 910 deliberately delays the illumination of the second light beam, but indicates that A beam of light passing along the track and the second beam passing along the same orbit along the first beam will naturally produce a time delay of 23 1358062 173l2 pif.doc. In operation 1120, the imprint/s compensation is illuminated. The third place on the storage medium 3G〇, the device 920 will compensate and illuminate the time delay between the information storage medium 3〇〇=the first-reproduced signal number, and perform: a second regenerative signal of the bundle, like The first - the regenerative signal News regeneration phase output - a final reproduced signal.

When the (4) high-energy phase super-resolution is reproduced and the jth first regenerative signal is deducted, if there is no news == again; the time delay between the signals, the deduction is caused by == ^ two =: the first regenerative signal is self It can be generated with a high energy: ^^ regenerated spot 1 is obtained, and the second regenerative signal is obtained from the spot 2 of the general reproduction generated by the low moon b. Then, the subtraction by the amplifier 921 shown in FIG. 9A 〆10 gives an appropriate magnification to the second reproduced signal, and the delay unit 922 t controls the first distance due to the spatial distance between the two spots i and 2. Time delay between the second regenerative signals

Late, if the time delay between the first and second regenerative signals is inaccurate, the deducted signal will be poorly specific. Of course, the time delay can be obtained by the spatial distance between the light spots 1 and 2, but various external disturbances may occur during the regeneration of the optical disc, for example, if the rotational speed of the spindle motor is slightly changed or has a radial direction or The tilt of the tangential direction occurs. 'The spatial distance between the spots on the actual disc changes. If the change in the spatial distance between the spots is not properly adjusted, the quality of the final reproduced signal will be poor. Figure 12 is a graph showing the results of signal jitter after 24 1358062 17312 pif.doc deducted from the delay time by simulation. In the simulation of Fig. 12, the linear velocity of the light spot is 5 m/s, and when the jitter is 1〇%, one is obtained because the range of ±〇.〇4T corresponds to ±0.03 nanoseconds, ±0·04Τ The time delay range is very narrow, so a unit that can accurately control the time delay is required. The time delay between the first and second reproduced signals can be controlled by the following methods: first, using jitter or Bit error rate (bER); second, using a front pit or a specific identification signal; and third, using a wobble signal. In the method of using the wobble signal, a point on the wobble signal that is discontinuous can be used. First, a method of using the jitter or bit error rate (bER) to accurately control the time delay between the first and second reproduced signals will be described. In this method, the jitter or bit error rate of the final reproduced signal obtained from the first and second reproduced signals is monitored, and the time delay between the first and second reproduced signals is compensated, so that the monitoring is performed. The jitter or bit error rate will be minimized. Fig. 14 shows a signal processor 142, which is an improvement of the recording/reproducing signal processor 92 in the data reproducing apparatus 900 of Fig. 9 or 1 and which is compensated by a jitter value. Referring to FIG. 14, the light of the first light beam reflected by the information storage medium 300 is detected by the first light detector 942a, and the light of the second light beam reflected by the information storage medium 3 is received by the second light. The detector 942b detects it. A delay unit 1421 of the signal processor 1420 receives the light output by the first light detector 942a, and delays the received light by a first delay time to compensate for the light spot i of the first light detector 942a. The time delay between the light spot 2 of the second light system II 942b, and the light 25 1358062 17312pif.doc & is supplied to an operation unit 1423, and the amplifier 1422 of the signal processor 1420 receives the second light detection. The light output from the detector 942b amplifies the received light and supplies the amplified light to an operation unit U23. The processing unit 1423 subtracts the second reproduction signal from the first reproduction signal. The first delay time (1) can be obtained by dividing the distance (d) between the first spot B1 of the first beam and the second spot B2 of the second beam by the linear velocity of the first spot, as shown in FIG. As shown, the delay unit 142i can delay the time delay between the first light spot and the second light spot by delaying the first regenerative signal for a first delay time. In the embodiment of FIG. 14, the delay unit 1421 transmits The jitter value can further compensate the time delay between the first and second spots. To be more explicit, the jitter compensation unit 1424 monitors the jitter value or the bit error rate of the final reproduced signal output by the operating unit 1423, and calculates the compensation value. The jitter or bit error rate is minimized, the second delay time is obtained by adding or subtracting the compensation value from the first delay time, and the second delay time is provided to the delay unit 1421, and then the delay time 1421 delays the first reproduction signal by the second delay. Time, precise adjustment of the time delay between the first and second spots. Figure 15 is a flow chart illustrating the use of jitter value compensation in accordance with an embodiment of the present invention. A method of time delay between the optical east and the second light beam. Referring to FIG. 15, in operation step 15, the distance between the first and second light spots and the linear velocity of the light spot can be calculated to calculate the first a delay time. Then, in the operation step 151, the delay of the detection of the light spot 1 by the first delay time and the delay detection signal operation and the detection signal of the light spot 2 26 1358062 l7312pif.doc can be A regenerative signal is obtained. In operation 1520, a jitter or bit error rate of the reproduced signal can be obtained, and a second delay time that can minimize the jitter or bit error rate of the reproduced signal is calculated. ^ In operation step 153, A regenerative signal is obtained by delaying the detection signal of the spot 2 by the delay time and delaying the detection signal and the detection signal of the spot 1.
