Description

564412 A7 B7 V. Description of the invention (彳) [Technical field to which the invention belongs] The present invention relates to the phase change of the recording layer material by irradiating laser light, which can record and reproduce information, and can rewrite the phase change. Type optical information recording media, in particular, it is possible to record in a high linear velocity area at a linear speed higher than 2 times the speed of DVD (7.0 m / s) and a linear speed higher than 8 times the speed of CD (9.6 to 11.2 m / s). Phase-change type optical information recording medium, optical information recording and reproducing method for the optical information recording medium, optical information recording and reproducing device, and manufacturing method of optical information recording medium. [Knowledge technology] One of the optical information recording media that can be recorded, reproduced, and erased by the irradiation of laser light is widely known as a so-called phase that utilizes crystalline-amorphous or crystalline-crystalline phase transition Change light information recording media. In particular, in the case of photomagnetic recording, it is easy to overwrite with a single light beam, and the optical system on the side of the recording / reproducing device is also simple. The need for a phase-change optical information recording medium has increased, and CD-RW, DVD-RW, and DVD-RAM are commercially available. In these recording media, in order to record more information more quickly, higher density or higher line speed is expected. Similarly, the recording speed of the optical information recording device is also increasing. At present, the maximum recording linear speed of the CD system is that CD-R becomes 12 times the speed of CD, and CD-RW becomes 10 times the speed of CD. Until now, the recording speed of CD-R and CD-RW has often reached the high speed of CD-R. Into. For example, when CD-RW is CD4x speed recording, CD-R is CD8x speed, CD10x speed, CD12x --------- Double Outfits 丨 (Please read the precautions on the back before filling this page) Order Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives, the paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -4-564412 A7 ___ B7 _ V. Description of the invention (2) Speed's to achieve more speed . (Please read the precautions on the back before filling this page.) As a result, although the optical information recording device is equipped with a high-speed corresponding spindle motor, semiconductor laser, and control system, it records CD-RW at a low speed. The reason is that a CD-RW disc holds information showing a standard recording linear speed or a maximum recording linear speed, and the optical information is recorded until the information is recorded and recorded at a high speed above the maximum recording linear speed. In addition, the CD-RW disc also holds information showing the minimum recording linear velocity. The recording linear velocity is designed to be almost the same to meet the minimum recording linear velocity and the maximum recording linear velocity. For optical information recording devices, the high-speed recording matches. There are concerns and cannot be implemented. Regarding the phase-change optical information recording medium, the linear velocity of the displacement of the medium usually needs to be optimally adapted to the recording linear velocity. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Here, the linear velocity of displacement refers to the following linear velocity. As shown in FIG. 18, the phase-change optical information recording medium is rotated at various linear velocities, while the semiconductor laser light is traced in the guide groove of the phase-change optical information recording medium, while being irradiated with the semiconductor laser light, Measure the reflectance or reflected light intensity of the optical information recording medium when the phase change recording layer is heated above the melting point and cooled. By this measurement, the measurement result shown in FIG. 19 is obtained. In Fig. 19, the linear velocity at which the reflectance or the intensity of the reflected light starts to decrease as the linear velocity increases (the displacement linear velocity in the figure is the linear velocity indicated by the arrow). As disclosed in detail in Japanese Patent Application Laid-Open No. 11-115313, it is important to control the displacement linear velocity of the phase-change optical information recording medium in order to maintain quality. Also, in the same gazette, the most appropriate displacement linear velocity of the 2X ~ 4 × (2 · 4 ~ 5.6m / s) linear velocity of the CD-RW media is 2.5 ~ This paper standard applies the Chinese National Standard (CNS) A4 standard (210X297 mm) Γ5Τ a 564412 A7 ___ B7__ 5. Description of the invention (3) 5.0m / s 〇 (Please read the precautions on the back before filling out this page) However, due to the high density, Narrow grooves, short wavelengths of laser light, and high NA (number of apertures), thermal characteristics of optical information recording media have greatly changed. In phase-change type optical information recording media with the same recording layer material or layer composition, Displacement linear velocities are very different. Therefore, for example, high density and high linear velocities above 0 ¥ 0 2 (7.〇111 / 8) linear velocity and above 8 0 (9.6 to 11.2 m / s) linear velocity. In the speed area, in order to record the phase-change optical information recording medium, it is necessary to review the recording layer material, layer composition, process conditions, and so on, and then design and record the linear velocity, the gauge of the guide groove, and the lightning of the recording device. The shift of the wavelength of the light, NA and other conditions Speed. In this context, the conventional CD-RW discs are designed to meet the minimum recording linear velocity and the maximum and maximum recording linear velocity because their recording linear velocity is almost equal, so their displacement linear velocity is less than the maximum recording linear velocity. The speed is 0.85 times, and it is impossible to record at a speed higher than this. The phase change recording materials used by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs to form the recording layer of the optical information recording medium are: GeTe, GeTeSe, GeTeS, GeSeS, GeSeSb, GeAsSe, InTe, SeTe, SeAs, Ge-Te- ( Sn, Au, Pd), GeTeSeSb, GeTeSb, Ag-In-Sb-Te and other materials. The special AglnSbTe material has the characteristics of high sensitivity and clear outline of the amorphous part, and has been developed as a recording layer for mark-edge and recording (see Japanese Patent Application Laid-Open No. 3-231889, Japanese Patent Application Laid-Open No. 4-19 1 089, JP 4-232779, JP 4-267192, JP 5-345478, JP 6_ 1 66266, etc.).

However, in such a recording layer, the repeated recording characteristics may not be sufficient to satisfy the requirements. Moreover, in the case of being used to disclose the recording layer of the information recording medium disclosed in Japanese Patent Application Laid-Open No. 4-191089, although the Divide ratio is improved and high-speed recording, but repeated recording characteristics are problematic. Furthermore, the information recording medium disclosed in Japanese Patent Application Laid-Open No. 1-303643 has adopted a new crystalline structure and has a high C / N ratio and repeating characteristics, and has become one that can provide excellent storage characteristics. Insufficient sensitivity and repetition characteristics. The structure used in the unrecorded portion (crystallized portion) of the recording layer of the information recording medium disclosed in Japanese Patent Application Laid-Open No. 4-232779 is a stable phase (AgSbTh) and an amorphous phase surrounding the stable phase. Mixed Beings. Therefore, although the repeated recording characteristics are improved, the existence of fine crystal grain boundaries in the crystallized portion is a cause of noise. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs has printed a compact recording-reproducible compact disc (CD-RW) that uses laser light with a wavelength of approximately 780 nm. The recording characteristics of optical information recording media will not cause important adverse effects, but in the realization of the use of laser light with a wavelength of less than 680nm, the DVD (Digital Versatile Disk: Digital Versatile Disk) has a recording density of approximately four times that of CD-RW — RAM or higher-density DVD-RW and other high-density recording can be an obstacle. Further, there is a problem regarding the repeated recording characteristics. This paper size applies the Chinese National Standard (CNS) A4 specification (210'〆297 mm) ΙΥΙ ~~ '564412 A7 ___ B7 V. Description of the invention (5) (Please read the precautions on the back before filling this page) Used The structure of the crystallized portion of the recording layer of the recording medium disclosed in Japanese Patent Application Laid-Open No. 4-267 192 is a phase separation of AgSbTea and other phases (stable phase or amorphous phase) from the same amorphous phase. Miscible state. When the other phases are in the amorphous phase, the same problems as in the case of the information recording medium disclosed in the aforementioned Japanese Patent Application Laid-Open No. 4-23 2779 arise, and when the other phases are stable crystalline phases, as will be described later. This is accompanied by a problem that good recording characteristics cannot be obtained. According to the circumstances of Japanese Patent Application Laid-Open No. 5-345478 and Japanese Patent Application Laid-open No. 6-16666, there are also problems similar to those described above. That is, the optical information recording medium using the phase change recording material of the AglnSbTe series or with the expansion of the lb group element, the Illb group element, the Vb group element, and the VIb group element as the recording layer, there is no stipulation on the composition of these elements. The knowledge of the recording media with single digits, therefore, there is no known technique for clarifying the function of the recording material of each constituent element. Therefore, there is no specific improvement based on the theory to repeat the characteristics or information recording of AglnSbTe recording layer and erase sensitivity. Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs and the phase change recording material used to form the recording layer of the phase change optical information recording medium, for example, as disclosed in US Pat. No. 353044 1 detailed description

So-called chalcogenide alloy materials such as Se-Sb, Ge-As-Se, In-Te, Se-Te, and Se-As. Furthermore, for the purpose of improving stability and high-speed crystallization, it is proposed to add people 11 (Japanese Patent Application Laid-Open No. 61-2 19692), 311, and 8-11 (Japanese Patent Application Laid-Open No. 61-270190) to the 06-but 6 series. (Gazette), Pd (Japanese Patent Application Laid-Open No. 62-19490) and other paper sizes are applicable to the Chinese National Standard (CNS) A4 specifications (210X297 public manager 1 ^ 564412 A7 B7) 5. Description of the invention (6) (Please read the Please fill in this page again for details) Materials. For the purpose of improving the repeated performance of recording / erasing, there are also materials that determine the composition ratio of Ge-Te-Se-Sb and Ge-Te-Sb (Japanese Patent Laid-Open No. 62- 73438, JP-A-63-228433, etc.). However, none of them can satisfy all the characteristics required for phase change recording media. In particular, recording sensitivity and erasing sensitivity The most important issues that need to be addressed are the improvement of erasing, the reduction of the erasing residue at the time of overwriting, and the longevity of the recording section and the unrecorded section. On the other hand, in JP 63-25 1 290 In Proclamation No., the proposal has diversification from a crystalline state of substantially three yuan or more A recording medium of a recording layer formed by a single layer of a composite. The so-called multi-component compound layer of substantially ternary means that the recording layer contains a compound having a stoichiometric composition of ternary or higher (for example, In3SbTe2). Above 90 atomic%. By using such a recording layer, the recording and erasing characteristics are improved. However, there are disadvantages that the erasing ratio is small and the laser power required for recording erasing has not been sufficiently reduced. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Further, in Japanese Unexamined Patent Publication No. 1-27733 8, the proposal has a value of (363 to 1-〇i-yMy (here, 0.4 $ aS0.7, yS0.2, M as An alloy consisting of at least one selected from the group consisting of Ag, A: 1, As, Au, Bi, Cu, Ga, Ge, In, Pb, Pt, Se, Si, Sn, and Zn) The light of the formed recording layer. Information recording medium. In addition, this system is basically Sb2Te3. By making Sb excessive, the high-speed erasing and repeating characteristics are improved, and the addition of μ is promoted to facilitate rapid erasing. In addition, the erasing ratio by DC light is also large. However, in this document, The erasing ratio of the time is not displayed, the paper size is suitable for the paper and the family (CNS) A4 specification (21GX297 mm) '— 564412 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 __B7 _ V. Description of the invention ( 7) The degree is not sufficient. The erasure ratio at the time of overwriting was confirmed by the inventors' review results, and the erasure residue was confirmed. Similarly, in Japanese Patent Application Laid-Open No. 60-177446, the use of the recording layer by (Ini-xSbx) i-yMy (0.55S xS 0.80, OS 0 · 20, M-based Au, Ag, Cu, Pd, Pt, A1, Si, Ge, Ga, Sn, Te, Se, Bi) Also, in Japanese Patent Application Laid-Open No. 63-228433, an alloy formed of Ge-Sb2Te3-Sb (excess) is used for the recording layer, but neither of them can satisfy characteristics such as sensitivity and erasure ratio. In addition, Japanese Unexamined Patent Publication No. 4- 1 63839 describes an optical information recording medium containing N in a Te-Ge-Sb alloy to form a recording film, and is disclosed in Japanese Unexamined Patent Publication No. 4-52 1 88 An optical information recording medium in which a Te-Ge-Se alloy contains at least one of these components as a nitride to form a recording film is described in Japanese Patent Application Laid-Open No. 4-521 89. N to form an optical information recording medium of a recording film. However, even those optical information recording media cannot obtain sufficient characteristics. As described above, in the conventional optical information recording medium, in particular, the recording sensitivity, the improvement of the erasing sensitivity, the prevention of the erasing ratio of the erasing residue during overwriting, and the length of the recording section and the unrecorded section Life span has become the most important issue to be solved. On the other hand, with the rapid spread of compact discs (CDs), the development of write-once compact discs (CD-R) that can be written only once has begun to spread to the market. However, even if the CD-R fails to write once, it cannot be corrected, and the disc that has failed to write becomes unusable and has to be discarded. Therefore, the paper size of this paper applies the Chinese National Standard (CNS) A4 specification (210X297 mm)-IQ-(Please read the precautions on the back before filling this page) 564412 A7 B7 V. Description of the invention (8) To be repaired The practicality of compact discs that can be rewritten. (Please read the precautions on the back before filling in this page.) An example of researched and developed is a compact disc that can be rewritten using a magneto-optical disc. Due to the difficulty of overwriting or interchange with CD-ROM and CD-R Because of its shortcomings such as poor performance, the practical development of phase-change optical discs (phase-change optical information recording media) that are in principle conducive to interchange guarantee is being actively carried out. Examples of researches on printing compact discs that can be rewritten using phase-change discs by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs include: Gu Gu (Others): The 4th Phase Change Record Research Seminar Workshop Preparatory Speeches , 70 (1 992), Kamano (other): Preparing speeches for the 4th phase change recording research seminar, 76 (1 992), West Sichuan (other): 4th phase change recording research seminar Lecture preparations, 82 (1 992), T.

However, none of these can fully satisfy the compatibility with CD-ROM or CD_R, record erasing performance, recording sensitivity, number of possible rewrites, number of reproductions, storage stability, and other comprehensive performance. These shortcomings are mainly due to the low erasure ratio of the recording material's composition and structure. Under these circumstances, it is expected that a large erasing ratio, suitable for high-sensitivity recording, and erasing phase-change recording materials, and further, a phase-change type compact disc that can be rewritten with high performance. The present inventors have proposed an AglnSbTe-based recording material as a new material finding solution to these disadvantages.

The orange book part III (version 1 · 〇) is a specification for a CD-RW with a 2x linear speed record (2.4 to 2.8 m / s). In such a low linear speed record, the recording time is long. Therefore, a rewritable compact disc which is recorded at a higher speed is desired. On the other hand, ways to improve the quality of the recorded signals of phase change recording have revealed various recording compensation methods. For example, in Japanese Unexamined Patent Publication No. 63-266632, PWM recording using a recording film having a high crystallization rate is effective in recording long amorphous marks using a pulse train. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and disclosed in Japanese Patent Application Laid-Open No. 63-266633 and detailed specification of US Patent No. 5 1 503 5-1, the laser energy at the front end and the tail end of the pulse train is increased. Make the irradiation time longer, and suppress the shaking of the position of the edge of the mark to improve the jitter. In addition, conventionally, it is known that, as described in Japanese Patent Publication No. 63-29336, an optical disc recording device irradiates light spots such as laser light on the optical disk while scanning, and modulate light spots such as laser light with information signal strength. The method of recording and recording information signals on a disc, and also knowing that there are information signals recorded on the disc that are reproduced, and by monitoring the amplitude of the reproduced signal or the length of the recording mark, the most appropriate adjustment and setting of the recording optical power or recording.

Let the signal width after modulation be 1 at nT. The recording wave pulse sequence at the time of signal recording or rewriting is: a pulse part fp having a time width X and a power level a, and a low level pulse having a time width power level b totaling T and The high-level pulses of the power level c interact with the electromagnetic pulses 多 of the multi-pulse portion mp which is continuous (η-η ′) times in total with the load ratio y, and the pulse portion op with a time width ζ and a power level d [J Let X, y, and z be 0.5TS xS 2.0T, 0.4S yS 0.6, 0.5T $ 1.0T, and let η 'be the positive integer of nj η (A and c) ^ (b in and d). Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs The conventional technology has greatly sought to improve the stability of signal quality, reliability, and versatility when repetitive recording signals are overwritten. However, in recent years, a rewriting type information recording medium, especially a phase change type optical information recording medium, requires a technology in which one information recording medium can record at a plurality of linear speeds (multi-speed recording). In addition, a higher recording speed is required, and a CAV recording that facilitates high-speed recording is also required. With regard to these technical requirements, the technologies described in JP 9-1 38946, JP 9-1 38947, and JP 9-21 9021 cannot be met. For example, in a recording strategy with fp, mp, and op that can be recorded at 4x CD linear speed, in the case of 8x speed recording and 10x speed recording, in 8x speed recording and ΐ〇χ speed, this paper scale applies to the Chinese country Standard (CNS) A4 specification (210X297 mm) _ 13-564412 A7 ___ B7 V.

Furthermore, the overwrite of the 10 × speed record for the part of the CD linear velocity 4x record, or the overwrite of the 4x speed record for the part of the CD linear velocity 1 Ox record, due to the signal quality of the overwrite due to different recording linear speeds The deterioration will become a problem. In addition, the deterioration of the signal quality in the overwriting of the part of the CLV record in the CAV record, or the overwriting of the part of the CAV record in the CLV record by a different recording method also becomes a problem.

Description of Invention (19)

The phase change recording material formed by Te is reviewed based on the results of X-ray diffraction and electron diffraction, especially the bond coordination number of each element. Great change. Generally, a compound containing a Vib group element such as Te, Se, s, etc. is called a chalcogen compound. A Vlb group element is bonded with a two-coordination bond, and the structure is flexible. Because the liquid phase freezes, it is easily vitrified Many are used as recording media. On the other hand, the coordination number of Ag of the lb family to Te is not clear. And the coordination number of In and Sb to Te are simply set to 3 coordination according to the 8-N rule. The actual coordination number is not clear. It is also unclear whether there is a difference in bond coordination number of each element between the crystalline state and the amorphous state. However, in the case of a recording medium, the bond coordination number of each element constituting the recording material is considered to affect the recording sensitivity of the disc characteristics or the erasing sensitivity or storage characteristics that are affected by the crystallization temperature, and the repeated characteristics cause Great influence. That is, according to Philip's theory of glass transition energy (J.C. Phillips: J., Non-Cryst, Solids 34 (1 979) 1 53), vitrification is the easiest when the average coordination number of constituent elements is 2.45. If such a coordination number is made, it is easy to vitrify, that is, the display can be recorded, and it becomes the goal of improving the recording sensitivity. In addition, a large number of bond numbers indicates that the bond energy is large and the crystallization temperature is increased, resulting in a decrease in erasure sensitivity, and further improvement of storage characteristics for preventing the disappearance of the mark. In addition, depending on the bond coordination number, 'not just a single phase' may be separated from a mixed phase. Based on this, it is considered that the repetitive characteristics may be deteriorated. In this way, the paper size is applicable to the Chinese National Standard (CNS) A4 specification (2 丨 〇 &lt; 297 mm) -22 · I ------------ Ί--IT-- ---- MW— (Please read the precautions on the back before filling this page) 564412 A7 _______B7 _ ^ __ V. Description of the invention (20) If you can control the key coordination number of each element that constitutes the recording material, consider it possible Significantly improve the characteristics of recording media. (Please read the precautions on the back before filling this page) As a result of an intensive review, the inventors found that the recording layer is formed of a recording medium made of Ag and In, Sb, and Te. (1) About Ag The coordination number for Te with In is different from the coordination number for Te in the phenanthrene crystalline state. When the crystal state is large, (2) Sb has the opposite coordination number for Te. (3) When the crystal state is small, (3) In these cases, it is configured as a single-layer, NaCl type, and when a large number of voids are generated on the C1 side occupied by Te, the individual disc characteristics are extremely good. In particular, when (a) the coordination number of Ag to Te in the amorphous state after film formation is in the range of 1.5 to 2.5, preferably in the range of 1.7 to 2.2, (b) the bonding of Te to Te The amorphous state after film formation is in the range of 3.0 to 3.8, preferably in the range of 3.4 to 3.7. When the crystalline state is in the range of 3.4 to 4.2, and preferably in the range of 3.5 to 3.8, (c) Sb For the coordination number of Te in the amorphous state range of 2.7 to 3.5, preferably in the range of 2.8 to 3.2, and when the crystalline state is in the range of 2.0 to 2.8, preferably in the range of 2.4 to 2.6, it is known that Excellent disc characteristics. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs for specific consideration: the amorphous coordination state of Ag after bonding to Te is 1.8, 4.0 after initial crystallization, and the coordination of Te against In In the case where the amorphous state after film formation is 3.5, the initial crystallization is 3.7, and the bond coordination number of Sb to Te is 3.0 in the amorphous state after film formation and 2.5 after initial crystallization, Let the composition of the phase change recording material (recording layer) be Ag5In7Sb6QTe28. In the non-crystalline state after film formation, the coordination number of Ag is 1.8. The paper size of Ag applies the Chinese National Standard (CNS) A4 specification (210X297 mm 1 -23-&quot; &quot; 564412 A7 B7 V. Description of the Invention (21) (Please read the precautions on the reverse side before filling out this page) As a result of cutting off the direction of the random network, it promotes crystallization. That is, it makes the initial crystallization easy and becomes uniform with fine crystal grains. Due to the polycrystalline state, the S / N ratio of the mark after recording is increased. Moreover, the average coordination number Z after the initial crystallization can be easily obtained from the above coordination number and composition, Z = 4 X 0.05 + 3.7 X 0.07 + 2.5 X 0.6 + 2.0 X 0.28 = 2.51, which is very close to Philip ’s glass transition ability. The average coordination number that is the easiest to vitrify is 2.45. This means that the record (vitrification) after initial crystallization is easy to achieve, that is, The recording sensitivity is good. It is printed by the Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs. After the initial crystallization, the structure is a single-phase cubic crystal of NaCl type. maintain Because of this state, the repeatability is also very good. Also, the coordination number after recording is the same as the coordination number after initial crystallization, and Z = 2.51 is maintained. Moreover, it is considered that the coordination of Ag that cuts off the network The number of digits also remains 4 after recording. At room temperature, the crystallization of the mark is extremely difficult to carry out, leading to an improvement in storage characteristics. In addition, most of the pores on the C1 side occupied by Te in the NaCl-type structure are recorded for recording The composition ratio of the materials is necessary to maintain the NaCl-type structure, and as a result, the recording layer is often kept in a single layer without causing phase separation, the repeatability is good, and a stable phase is maintained. Furthermore, in order to obtain the present invention In the optical information recording medium, the film formation method of the recording layer is expected to adopt the method described in the application item 26. That is, when forming the film, the temperature is 10 ° C / mi η to 50 ° C / mi η, preferably 3 The substrate is formed by heating the substrate at a temperature rise rate in the range of 0 ° C / mi η to 40 ° C / mi η. At present, it is not known why the bond coordination in the amorphous state and the crystalline state according to this method There will be a difference in the number. Also, regarding film formation during film formation Although there are multiple papers for this key, the paper size is suitable for financial rewards (CNS) Α4 size (21GX297mm) -24-'564412 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 _ B7 V. Description of the invention (22) The influence of less, but it is not clear. One of the possible reasons is that the structure of the recording layer is changed from a close-range order to a middle-range order based on the substrate temperature rise during film formation. Also, DC sputtering is more than Rf sputtering.

The ratio of added elements is 0.1 to 20 atomic%, preferably 0.1 to 15 atomic%. By setting it to 20 atomic% or less, the initial stage can be performed well. In addition, the above-mentioned materials have different displacement linear velocities depending on their composition ratios, and the most appropriate recording linear velocities are also different. Therefore, it is necessary to adjust the composition ratios of the materials according to the recording linear velocities and linear velocity regions of interest, Controls displacement linear velocity. As a result of the review so far, it has been found that the composition ratio of Te is related to the high linear velocity of displacement. For the quality requirements of the phase-change optical information recording medium used in Embodiment 1, not only can it be recorded and erased, but also the reproduction stability or signal life of the signal when recording in a high density and high linear velocity area ( Reliability).

The hardness of the bell pen is preferably at least Η even if it is rubbed with a cloth. If necessary, it is also effective to mix conductive materials to prevent electrification to prevent the adhesion of dust and the like.

The film thickness of the third protective layer is 1 to 40 nm, and preferably 2 to 30 nm. If it is above 1 nm, it is easy to form a stable interface layer.

Invention description (29) The gauge, laser light wavelength, NA, and laser power vary, and the gauge varies from 0.2 to 1.4 // m In the optical information recording medium, it is important to find that the linear velocity of the displacement when the focused semiconductor laser light DC is irradiated to the groove portion or the island portion of the guide groove is 6 to 24 m / s. When the linear speed of the displacement is above 6m / s, it can correspond to the linear speed area of the DVD such as 2X (7.0m / s) or more, and CD 8 × (9.6 to 11.2m / s) Its record. On the other hand, when the displacement linear velocity is less than 2 4 m / s, the recording sensitivity of a region suitable for recording at a linear velocity of recording is not easily reduced. Based on the pulse strategy described later, a good quality recording can be performed. Generally, in the case of repeated writing in a phase-change optical information recording medium, it can be seen that the jitter increases when the recording is performed twice, and the jitter is reduced when the writing is repeated more than three times. After ten times of repeated writing, the jitter is stable. . This phenomenon is apparent during high-speed recording for the purpose of the first embodiment. Therefore, the most important practical quality of the phase-change optical information recording medium is the jitter during the two recordings. Fig. 2 shows the phase change of various shifted linear velocities produced on a substrate using information having the lowest recording linear velocity CD 4 times (4.8 m / s) and the highest recording linear velocity CD 10 times (12.0 m / s). The optical information recording medium has a recording power with less jitter when performing two recordings and a recording strategy of jitter during two recordings. The jitter is the same as when CD is being reproduced at 1x speed. 35nm (nanosecond) or less meets the specifications. From FIG. 2, it is known that the linear velocity of the shift of the original CD4 speed and the CD10 speed is small, and the displacement linear speed is 12 m / s. The mound paper size is in accordance with the Chinese National Standard (CNS) A4 specification (210X297 mm) Γ32-(Please read the precautions on the back before filling in this page) 564412 A7 B7 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 3) However, the CD-RW recording medium with the lowest recording linear speed CD4 times (4.8m / s) and the highest recording linear speed CD10 times (12.0m / s) has a displacement linear speed of 9m / s, which is The maximum recording linear speed is about 0.75 times, which matches the minimum recording linear speed of CD4 times, and does not match the CD10 times. In order to make higher-speed recording possible for the purpose of Embodiment 1, especially in order to allow users to experience high speed, it is necessary to achieve a recording linear speed increase of 20% or more of the 10 times the maximum recording linear speed CD (ie, 14.4m). / s), in order to meet the specification below 35ns, judging from FIG. 2, it is judged that a shift linear velocity of more than 9.5m / s is required. That is, a displacement linear velocity of 0.8 times or more the highest recording linear velocity is required. Furthermore, in order to achieve more than the high-speed recording, for example, CD 16x speed (19.2m / s), CD20x speed (24m / s), CD24x speed (28.8m / s), requires 12, 16, 19m / s or more Shift linear speed. On the other hand, in order to record at a minimum recording linear velocity of 4.8 m / s, the jitter should be less than 35 ns, and it is known that the shift linear velocity needs to be 25 in / s. That is, the maximum recording linear velocity is approximately twice the maximum recording linear velocity or less, which is the upper limit of the recording linear velocity. Although the above description is based on a CD-RW recording medium as an example, other phase-change optical information recording media are also the same. In order to achieve higher-speed recording, it is desirable that the recording medium has at least 0.8 times the maximum recording linear speed. 'It is ideally 0.85 times or more, and more preferably 0.9 times or more the linear speed of displacement. Also, the cd-RW recording media of various displacement linear velocities described in FIG. 2 are produced by appropriately selecting the composition of the recording layer, the thickness of the recording layer, the impurities of the recording layer, the material of the reflective layer, the dielectric material, and the conditions of the initializing process.

Description of the invention (31) The linear displacement speed can be adjusted according to the materials, film thickness, and process conditions of the above-mentioned constituent layers. For example, if the composition ratio of the Ag and Ge of the recording layer material is increased, the shift line speed can be made slower. If the composition ratio of In and Ga is increased, the shift line speed can be made faster. If the film thickness of the recording layer is made thicker, the displacement linear velocity can be made slower. If the film thickness is made thin, the displacement linear velocity can be made faster. Regarding the second protective layer and the reflective layer, if the thermal conductivity is made larger, the displacement linear velocity can be made slower, and if the thermal conductivity is made smaller, the displacement linear velocity can be made faster. As an example of process conditions, in the case where the recording layer, the first protective layer, the second protective layer, and the third protective layer are formed by a sputtering method, if the temperature of the substrate to be put is low, the displacement linear velocity can be increased. Slower, if the temperature of the substrate is high, the linear speed of the shift can be increased. In addition, the coexisting gas at the time of sputtering is outside Ar, and if N2 and O2 are added, the displacement linear velocity can be slowed down. At this time, at the beginning of the target life, the displacement linear velocity becomes faster, and at the latter half of the target life, the displacement linear velocity becomes slower. In addition, the linear velocity of the shift can be adjusted based on the conditions of the initial linear velocity and laser power. The combination of the above conditions can determine the linear velocity of the shift, and by adjusting these in a balanced manner, the linear velocity of the shift can be controlled to a desired level. In the optical information recording medium corresponding to the high linear velocity of the first embodiment, it is desirable to make the linear velocity of the initialization slower than the linear velocity of the shift. If the initial linear velocity is faster than the linear velocity of the shift, the paper size applies the Chinese National Standard (CNS) A4 (210X297 mm) for the temperature of the recording layer: 34-(Please read the precautions on the back before filling this page ) 564412 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 _ B7 _ V.

Moreover, if it is 1.6 times or less, the temperature rise of the recording layer can be performed well, uniform crystallization can be performed, uniform initialization can be performed, and disturbance of the RF signal can be prevented.

Description of the invention (41) [Embodiment 2] The phase-change type optical information recording medium according to Embodiment 2 uses Ag, In, Sb, and Te as main constituent elements, and is further characterized by Add at least one specific element selected from Groups 111b, IVb and 5b of the periodic table. Therefore, compared with the conventional optical information recording medium of phase change type, it has sufficient media characteristics at high line speed and high density recording, especially the phase with excellent storage reliability after repeated recording, initial stage and after repeated recording. Hereinafter, the change recording material 0 will be described in more detail. The optical information recording medium according to the second embodiment is a layer in which a lower protective layer, a recording layer, an upper protective layer, and a reflective layer are sequentially laminated on a substrate. The recording layer is composed of Ag, In, Sb, and Te, which have already been described. Furthermore, at least one specific element selected from Groups 111b, IVb, and 5b of the periodic table is added thereto. In addition, the recording layer in the medium after film formation is changed to a so-called initial phase from an amorphous phase to a crystalline phase, thereby forming a crystalline phase. Here, in Embodiment 2, the atomic ratio of each of the main constituent elements Ag, In, Sb, and Te preferably has a relationship of the following formula (2): (Agaln ^ Sbr) 1-5 Te ό (2) (In the formula, 0.1 &lt;. &Lt; 10, 1 $ ^^ 20, 90 $ 7 &lt; 100, 0 + y8 + r = 100, 0.2S5 $ 0.35.) When expressed, the above When the recording layer forms a crystalline phase, a NaCl type structure is formed uniformly.

The initial stage of invention description (42) and the tendency to repeat recording characteristics. With this, it becomes a eutectic composition that does not easily cause composition changes even if the phase changes of the amorphous phase and the crystalline phase are repeated for recording. In addition, for high-speed crystallization at a higher line speed, it is appropriate to maintain this state while increasing Sb and In and decreasing Ag. In the second embodiment, regarding the crystallization rate, first, Sb Compared with Te, the atomic radius is large. In the amorphous phase, the coordination number for Te bonds is about 3, which is easy to cause crystallization, and the crystallization speed is fast. Moreover, it will also cause at a relatively low temperature. So, the amount of Sb In many cases, the storage reliability is significantly deteriorated. In addition, In has a larger atomic radius than Sb, and the bond coordination number is also in amorphous, higher than Sb, about 3.5 coordination, and the crystallization speed is fast. Although the details are not clear, it will crystallize at a higher temperature at a higher temperature, and it is difficult to cause crystallization at a temperature of 70 to 80 ° C. Or it is considered that In has a function that prevents crystallization by Sb Regarding its crystallization rate, although the atomic radius of Ag is larger than Te, the coordination number is about 2 and the amorphous phase is stable, so the crystallization rate is relatively slow. Also, in high-speed recording, Even if repeated recording is performed, it is not easy to cause composition changes, and high-speed crystallization is required to ensure the most appropriate composition range that can ensure the reliability of storage. However, even within the above composition range, the characteristics of all parts are limited. In particular, there is a limit. Reliability in preservation is not easily ensured in high-speed recording. 'Therefore, from the viewpoint of the factual relationship as described above, the reliability of the recording medium is assured. It has excellent repetitive recording characteristics in high-speed recording.

Description of the invention (43) Ensure the stability of the amorphous phase environment As an added element to the above main constituent elements, at least one element of Groups Illb, IVb, and 5b of the periodic table can be appropriately added in Embodiment 2. (Please read the precautions on the back before filling this page) For these additional elements, the bond energy of the constituent element Te is 200 k; f / mol or more, or in order to increase the crystallization speed, the atomic radius of these additional elements is preferably from 0.1 nm to 0.20 nm. In addition, the bond can be as large as possible, and it is preferable that the bond is more than 250 k / mol. In addition, even if it is made large, it is preferable to use 500 kJ / mol or less because a large amount of energy is required to change the phase. Furthermore, the element with a smaller atomic weight among the Illb, IVb, and 5b groups of the periodic table of the element has a tendency to increase the crystallization temperature. From the viewpoint of preserving reliability, it is best to add An element having a smaller atomic weight than Sb or In, which is a constituent element. Therefore, among these additional elements, for example, B, Al, Ti, C, Si, Ge, Sn, Pb, P, As, and Bi, etc., the atomic radius and the bond energy to Te are shown in Table 3. From this table, it is preferred that Al, Si, Ge, Sn, P, and the like be added as appropriate. Among these, Ge is particularly suitable.

Description of invention (45) If the amount of the element is too much, it tends to slow down the crystallization rate and deteriorate the repeatability. In addition, the element with a smaller atomic radius than In and Sb, and the larger the bond energy, the stronger the tendency. Therefore, in the range of the most appropriate addition amount, the addition amount of I η amount is always preferably smaller. In particular, when the amount of In is small, there are elements that significantly reduce the crystallization rate. On the other hand, Ti, Pb, and Bi have the effect of increasing the crystallization rate. If it is too much, the repeated recording characteristics are good, but the crystallization temperature is significantly reduced, which tends to reduce the reliability of storage. In the second embodiment, when the above-mentioned recording layer is used for a recording medium, the lower protective layer and the upper protective layer are formed of ZnS and Si0, and the molar ratio ZnS: Si can be appropriately set. 2 is a protective layer in the range of 50: 50 ~ 90: 10, preferably around a molar ratio of 80:20. If necessary, oxides, nitrides, or mixtures thereof other than ZnS-SiCh-based composites can also be suitably used. The film thickness of the lower protective layer is from the viewpoint of maintaining the environmental resistance of the recording layer and preventing the substrate from peeling off due to thermal stress during film formation. The film thickness is preferably in the range of 25 to 250 nm. In addition, the upper protective layer is a film thickness that suppresses deformation due to an increase in thermal stress during repeated recording, a decrease in adhesion, and a thermal conductivity during recording that does not reduce the recording sensitivity. The film thickness is 5 to 25 nm. The range is better. In addition, the reflective layer is generally suitable as a low-cost one. Although a metal such as A1 or Ag or an alloy thereof is used, a metal or an alloy having a higher thermal conductivity than the protective layer may be appropriately used as required. The film thickness can be appropriately used in the range of 50 to 200 nm. This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) -48-(Please read the notes on the back before filling out this page) Order 564412 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ___ B7 __ 5 (46) From the above, the phase-change optical information recording medium according to the second embodiment is, for example, a rewritable recording medium, and a wavelength in a range of 400 to 680 nm can be appropriately recorded and reproduced. In addition, in order to increase the recording density, it is possible to make it easier by setting the aperture number of the objective lens to 0.60 or more. In addition, the recording usually includes both the case of recording on a groove of a substrate, the case of recording on a groove, and the case of an island between a groove and a groove. In short, in order to increase the density and capacity, it is possible to narrow the track pitch of the substrate. The pitch is 0.8 // m. The depth of the groove is preferably 15 nm to 60 nm. If it is below 15nm, there is no stable trace. From the above, the recording method using the optical information recording medium according to the second embodiment shows the characteristics of high-speed, high-density recording and reproduction in FIG. 5. It can be clearly seen from FIG. 5 that the light emitting pulses of the laser light irradiated on the recording medium have three levels of recording, erasing, and bias, and the recording and erasing power is higher than the reproduction power. Regenerative power below. The bias power is the power after the recording power is irradiated, and it is necessary to form an amorphous phase. This pulse is further formed by a leading pulse (1 pulse), a complex pulse train, and a cooling pulse (1 pulse). To make the edge of the recording mark steep, it is necessary to make the recording position and the length of the recording mark correct. Such a recording light emission pulse is suitable for high-speed recording, and the material and composition of the recording layer are most suitable. As a result, the recording frequency was approximately 80 MHz at 20 MHz, and the maximum recording power was 15 mW. Recording and reproducing line speed can correspond to both CLV or CAV. The maximum line speed is about 15m / s, and more preferably 3.0m / s and 12m / s.

Description of the invention (50) When the substrate is a low heat-resistant material such as polycarbonate resin, it is desirable to provide a lower heat-resistant protective layer. The material of the substrate 21 is usually glass, ceramic or resin, and a resin substrate is suitable from the viewpoints of moldability and cost. Specific examples of the resin are: polycarbonate resin, acrylic resin, epoxy resin, polystyrene resin, acrylonitrile-styrene copolymer resin, polyethylene resin, polypropylene, silicon resin, fluorine resin, ABS Resin, urethane resin, etc., but from the viewpoint of processability, optical characteristics, etc., polycarbonate is preferred. The shape of the substrate is not limited to a dish shape, and may be a card shape or a thin plate shape. (ZnS) SQ. (SiCh) 2 is used as the heat-resistant protective layer, that is, the dielectric layer. Film formation is performed by a sputtering method. Because this dielectric layer has a function as a heat-resistant protective layer and a function as a light interference layer, it is necessary to make the most of these functions. Therefore, the film thickness is set to 200A to 3000A, and preferably 3 50A to 2000A. When it is less than 200A, the function as a heat-resistant protective layer is lost. If it exceeds 3000A, interfacial peeling is likely to occur. The recording layer of the third embodiment is generally formed by a sputtering method, and the film thickness is 100A to 1,000A, and preferably 200A to 350A. If it is thinner than 100A, the light absorption energy is reduced, and the function as a recording layer is lost. On the other hand, if it is thicker than 1,000A, the transmitted light will be reduced, and the interference effect cannot be expected. The reflective layer is formed of, for example, an Al alloy. The film formation is performed by a sputtering method. The film thickness is 500A to 2000A, and preferably 700A to 1,500A. In the following, the embodiment will be described in more detail by way of Example 5 1 to Example 5 (please read the precautions on the back before filling this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) 564412 A7 B7 V.

Here, the heat-resistant protective layer is made of (ZnS) 80 (SiO2) 20, and the reflective layer is made of Al-Ti alloy. The film thickness of the lower heat-resistant protective layer is 1200 A, the film thickness of the upper heat-resistant protective layer is 350 A, and the film thickness of the reflective layer is 800 A. The film thickness of the recording layer was 210 A, and DC sputtering was performed under the following sputtering conditions. Also, what is the recording layer used for?

Description of the invention (60) : (Please read the precautions on the reverse side before filling out this page) (1) In the case of Ag: In the case of amorphous, depending on the film formation conditions, the bond coordination number is different, but it is in the range of 1.5 to 2.0. In the case of crystalline materials, the bond coordination number in the case of crystalline materials is larger than that in the case of amorphous materials in the range of 3 · 8 to 4.3. (2) In the case of In: In the case of amorphous, in the range of 3 ~ 丨 ~ 3.6, in the case of crystalline, in the range of 3.6 to 4.0, the same as Ag, the bond coordination number in the crystalline The bond coordination number is larger than that in the amorphous state.

The signal characteristics of the optical information recording media of 1 to 55 in these embodiments are all good, and recording can be performed at a wide range of power from 8 mW to 13 mW, and the sensitivity is high. In addition, the repeatability can be used up to 20,000 times, which is extremely good. Regarding storage characteristics, it was confirmed that the signal characteristics did not deteriorate even after being left for 200 hours under the conditions of 80% RΗ and temperature and humidity of 80 ° C, and had high weather resistance. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. On the other hand, in Comparative Examples 51 and 52, it is known that the bond coordination number of Ag is not in the amorphous state and the crystalline state. small. According to the difference in film formation conditions from the examples, the reasons for the differences between the results of the comparative examples and the examples are unknown, but among the X-ray diffraction spectra of comparative examples 51 and 52 and those of examples 51 to 55, Confirm the difference. That is, Comparative Example 51 is a NaCl type, which is the same as Examples 51 to 55, but has a (220) plane and grows on a (311) plane. Also, in Comparative Example 52, the paper size is in accordance with the Chinese National Standard (CNS) A4 specification (210X297 mm) -63-564412 A7 B7 5. In the description of the invention (61), the (220) plane can be regarded as a separation of 2. The difference in the individual X-ray diffraction spectra of Comparative Examples 5 and 52 and Examples 5 to 5 5 also appeared in the signal characteristics of the obtained optical information recording medium. That is, in Comparative Examples 5 1 and 52, compared with Examples 5 1 to 55, it was seen that the repeat recording characteristics were greatly reduced in addition to the decrease in sensitivity. This is the structure of the display recording layer (recording film), especially the key coordination number, which is strongly related to the signal characteristics of the optical information recording medium. [Embodiment 4] Fig. 14 is a diagram for explaining an example of an optical information recording medium according to Embodiment 4. The substrate structure includes a first protective layer 32, a recording layer 33, a second protective layer 34, a reflective layer 35, and a thick coating layer 36 on a substrate 31 having a guide groove. Furthermore, it is desirable to have a print layer 37 on the thick coating layer and a hard coating layer 38 on the substrate mirror surface. The material of the substrate is usually glass, ceramic, or resin, and a resin substrate is suitable in terms of moldability and cost. Examples of the resin include polycarbonate resin, acrylic resin, epoxy resin, polystyrene resin, acrylonitrile-styrene copolymer resin, polyethylene resin, polypropylene, silicon resin, fluorine resin, ABS resin, Urethane resin, etc. Among these resins, polycarbonate and acrylic resins which are excellent in moldability, optical characteristics, and cost are preferred. However, the optical information recording medium of Embodiment 4 is applied to a rewritable compact optical disc (CD- RW), the following specific conditions are expected to be imposed.

The depth of the description of the invention (62) is 250 ~ 650A, suitable for 300 ~ 550A. Although the thickness of the substrate is not particularly limited, 1.2 mm or 0.6 mm is suitable. (Please read the precautions on the back before filling this page.) The recording layer 33 is recorded as a material containing a 4-element phase change type recording material of Ge, Ga, Sb, and Te as the main component (amorphous). ) Sensitivity. Recording speed, erasing (crystallization) sensitivity, erasing speed, and erasing ratio are very good, which is very suitable. However, since GeGaSbTe has the most suitable linear velocity for recording based on its composition ratio, the composition ratio of GeGaSbTe needs to be adjusted based on the linear velocity and the linear velocity region for its purpose. As a result of the review so far, it has been found that the composition ratio of Te in the GeGaSbTe recording layer is highly correlated with the recording linear velocity. The quality required by the optical information recording medium of Embodiment 4 not only can record and erase, but also requires the stability of signal reproduction or the life of the signal. A recording layer that satisfies these comprehensively is superior to GeGaSbTe, and the individual composition ratios 61 :, / 9, 7, 5 (atomic%) are set to (^ + / 3 + 71 + 5 = 100) at: 0.1 ^ a ^ 7.0 The printing of 61 $ r $ 75 22 ^ 5 ^ 30 by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs is effective.

When Ge exceeds 7.0 at%, Ga exceeds 9 at%, and Sb exceeds 75 at%, the regeneration stability of the signal or the life of the signal is insufficient. The content of Te greatly affects the recrystallization linear velocity. Even if it is controlled by the thickness of the recording layer or the thermal conductivity of other layers, it is preferably at least 22 at% or more and 30 at% or less. ^ The paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -65-'~ &quot; &quot; 564412 Α7 Β7 Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs and Consumer Cooperatives The method of reproducing stability or signal life is to add in the recording layer by: In, Zn, Sn, Si, Pb, Co, Cr, Cu, Ag, Au, Pd, Pt, S, Se, Ta, Nb, V , Bi, Zr, Ti, A1, Mn, Mo, Rh'C, N, and at least one selected from the elements are effective. The deterioration of the signal reproduction or the reduction of the signal life is caused by the crystallization of the amorphous mark. In order to suppress the crystallization of the amorphous mark, it is effective to add at least one element selected from the foregoing elements to the recording layer. Although this mechanism is not clear, these elements are considered to enter the voids in the space of GeGaSbTe, form chemical bonds, form compounds or alloys with GeGaSbTe, and become an additive to suppress the crystallization of amorphous marks. Therefore, elements with small atomic radii, large chemical bond energy with GeGaSbTe, and many chemical bonds are effective. In particular, C, N, O, Si, Sn, and Ag are effective. The amount of these added elements is effective at 7at% or less of the recording layer. By setting it to 7 at% or less, the recording erasing characteristic originally possessed by the GeGaSbTe recording layer can be maintained, and erasing residues can be suppressed. In addition, high linear speed recording and erasure reliability of optical information recording media are extremely important items. In the fourth embodiment, regarding the relationship between the composition of Ge and Ga, at -8 S α · / 3 S 3, it was found that the balance between high line speed correspondence and storage reliability can be taken into account. When α-/ 3 exceeds 3, records can be seen. The optimum line speed at the time of erasing tends to be slower. When α Α is less than -8, the storage stability of the optical information recording medium is insufficient. Therefore, at -8 $ α-/ 3 S 3, it is effective in achieving the balance between the two characteristics. Furthermore, the linear velocity becomes higher, and it is important to ensure the reflectance of the optical information recording medium, especially the reflectance at the time of initializing.

(Please read the notes on the back before filling this page) The film thickness of the recording layer is preferably 10 ~ 50nm, more preferably 12 ~ 30nm. Furthermore, considering the initial characteristics, overwrite characteristics, and mass production characteristics of jitter, etc., 14 to 25 nm is suitable. When it is 10 nm or more, the light absorption energy is not reduced, and good recording characteristics can be obtained. Furthermore, by making it 50 nm or less, high-speed and uniform phase change can be performed. Such a recording layer is formed by various vapor growth methods such as a vacuum evaporation method, a sputtering method, a plasma CVD method, a photo CVD method, an ion plating method, an electron beam evaporation method, and the like. Among them, the sputtering method is excellent in mass productivity and film quality.

If necessary, impurities may be contained. Further, if necessary, a plurality of dielectric layers may be formed. However, the melting points of the first protective layer and the second protective layer need to be higher than those of the recording layer. The materials of the first protective layer and the second protective layer can be formed by various meteorological growth methods, such as a vacuum evaporation method, a sputtering method, a plasma CVD method, a photo CVD method, an ion plating method, and an electron beam evaporation method. form. Among them, the sputtering method is excellent in mass productivity and film quality. The film thickness of the first protective layer greatly affects the reflectance. In order to apply the Chinese National Standard (CNS) A4 specification (210X297 mm) at 78Onm and this paper size Γβ7-— ~ 564412 A7 B7 V. Description of the invention (65) (Please read the precautions on the back before filling out this page) 65 The reproduction wavelength of 0 nm satisfies the reflectivity of the CD-RW disc specification from 0.15 to 0.25, and the first dielectric layer is required to be 65 to 130 nm. By setting the film thickness to this, it is possible to obtain reflectance that satisfies the reproduction wavelength of a DVD of 65 Onm and interchangeability of DVD reproduction. The film thickness of the second dielectric layer is preferably 15 to 45 nm, and more preferably 20 to 40 nm. By setting it to 15 nm or more, it can function well as a heat-resistant protective layer, making it difficult to cause a decrease in sensitivity. On the other hand, by making it 45 nm or less, interfacial peeling is less likely to occur, and it is possible to prevent degradation of repeated recording performance. As the reflective layer, a metal material such as Al, Au, Ag, Cu, Ta, Ti, W, or the like, or an alloy thereof can be used. As the additive element, Cr, Ti, Si, Cu, Ag, Pd, Ta, or the like can be used. Such a reflective layer can be formed by various vapor growth methods, such as a vacuum evaporation method, a sputtering method, a plasma CVD method, a light (乂 0 method, an ion plating method, an electron beam evaporation method, etc.), an alloy or The film thickness of the metal layer is preferably 70 to 200 nm, and is suitably 100 to 160 nm. Also, an alloy or metal layer may be multilayered. In the case of multilayering, the film thickness of each layer needs to be at least 10 nm or more, the total of the multilayered film The film thickness is preferably 50 ~ 160nm.

By making it 2 / zm or more, Full abrasion resistance can be obtained. 6 // m or less, the internal stress is not large, and it is not easy to affect the mechanical characteristics of the disc.

Description of the invention (66) Pencils with large scars are better than Η. It is also effective to mix conductive materials to prevent electrification to prevent dust from adhering if necessary. (Please read the back first) Please note this page before filling in this page) Generally, in the case of multi-speed recording and CAV recording, at low linear speeds, it becomes excessive recording power, and at high linear speeds, it becomes insufficient recording power. Therefore, the recording linear speed and recording The balance of power is very important. The specific method is that the higher the line speed recording is, the higher the power is required, which can generally be regarded as CD-R, etc. Figure 15 is a diagram for explaining the pulse waveform recording. In the fourth embodiment, it was found It is effective to increase and decrease the load ratio of the multi-pulse section (hereinafter referred to as the mp section) at the recording linear velocity in FIG. 15. The load ratio described here is a low level pulse of the mp section. The time of the power level b is broadly removed by the time of the mp section. Moreover, this information recording method is particularly effective in an information recording medium whose recording layer is mainly composed of Ge, Ga, Sb, Te. This is based on Ge, The thermal physical properties of the recording layer whose main components are Ga, Sb, and Te match this recording pulse wave. Fig. 16 shows a multi-speed recording waveform of a 4x ~ 1 Ox recording of CD-RW, which is an example of Embodiment 4. This example also corresponds to a CAV record of 4.8m / s on the inner periphery and 12.0m / s on the outer periphery. In this example, the linear velocity of the record is 4.8, 9.6, and the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economy printed 12.Om/s. The load ratio of the mp section is 0.625, 0.5, and 0.375. In accordance with the increase in the recording linear velocity, the load ratio of the mp section is reduced. In the low linear velocity recording of 4.8m / s, the recording pulse of the mp section is made thinner to reduce unnecessary thermal damage. Furthermore, by increasing the cooling time of the mp section, the position deviation of the recording edge can be reduced. Of the tag. On the other hand, in the high linear velocity recording at 12 · Om / s, by widening the recording pulse in the mp section, the recording film is given as much energy as possible that can be phase-changed. Also, due to the high speed, the cooling time of the m P section is applicable to the Chinese national standard (CNS) A4 specification (210X297 mm): 69- 564412 Α7 Β7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economy At the end of (67), the quenching condition of the recording layer is complete, and a mark with less positional deviation of the edge can be recorded. In the phase change type optical information recording medium accompanied by the melting and rapid cooling of the recording layer, the burr load of the mp part of the recording pulse is around 0.5 'to achieve the balance of melting and rapid cooling of the recording layer, and the quality On the favorable. Therefore, in consideration of the drive-media matching, setting the load ratio of the mp section to 0.5 at any recording line speed for multi-speed recording becomes a problem. In the fourth embodiment, the recording linear velocity ratio (lowest recording linear velocity + highest recording linear velocity) / 2 in which the load ratio of the mp section is 0.5 is large, and it is effective below the maximum recording linear velocity. The recording linear speed that is widely used in a drive section capable of multi-speed recording is the highest recording linear speed. In the CAV recording, a high-speed recording is performed on an outer peripheral portion that is easily affected by mechanical characteristics. Therefore, even in CAV recording, the signal quality of high-speed recording is more important. Therefore, in practice, it is effective to set a recording pulse waveform having a load ratio of 0.5 or more on the high-speed recording side for a recording with higher reliability on the mp section with higher reliability. Furthermore, it is more effective to make the load linear ratio of the mp part to be 0.5 and the recording linear velocity to be greater than 0.55x (the minimum recording linear velocity + the maximum recording linear velocity), and below the maximum recording linear velocity. Fig. 17 is a diagram illustrating an embodiment of a recording / reproducing apparatus for an optical information recording medium according to the fourth embodiment. The phase change type optical information recording medium is rotationally driven by the driving means formed by the spindle motor, the light source formed by the semiconductor laser is driven by the laser driving circuit of the light source driving means, and the pickup head for recording and reproduction is used by the foregoing The optical system shown in the last figure for semiconductor laser transmission is applicable to this paper.
