Description

  The present invention relates to an optical recording medium, and more particularly to an optical recording medium that can be recorded and reproduced by blue laser light, which is a kind of visible laser. In addition, the present invention relates to a novel triazine compound.

  CD-R (CD-Recordable) is widely used as an optical recording medium corresponding to the compact disc (hereinafter abbreviated as CD) standard. Although the storage capacity of the CD-R is about 680 MB, with the dramatic increase in the amount of information, there is an increasing demand for higher density and larger capacity for information recording media.

  As means for increasing the density of the recording medium, it is possible to reduce the beam spot by shortening the wavelength of the laser used for recording and reproduction and increasing the numerical aperture (NA) of the objective lens. Can be mentioned. As a short wavelength laser used in the optical disc system, a red laser of 500 nm to 700 nm, further about 630 nm to 690 nm, specifically, 680 nm, 670 nm, 660 nm, 650 nm, 635 nm, etc. has been put into practical use. Thus, by shortening the wavelength of the semiconductor laser, increasing the numerical aperture of the objective lens, data compression technology, and the like, it has become possible to produce an optical recording medium capable of recording moving images and recording large amounts of information. Optical recording media proposed to date include magneto-optical recording media, phase change recording media, chalcogen oxide optical recording media, and organic dye optical recording media. From the viewpoint of ease, the organic dye-based optical recording medium is considered to have an advantage. In light of these circumstances, an oscillation wavelength of 630 to 690 nm that can be played back by a commercially available DVD video player or DVD-ROM player as an optical recording medium capable of recording and playing back a moving image with a higher density than a CD and equivalent to TV quality. A write-once type digital multipurpose disc (hereinafter abbreviated as DVD-R) has been developed as a write-once type optical recording medium capable of recording with a red semiconductor laser. DVD-R is a once writable optical recording medium having a recording capacity of 3.9 GB or 4.7 GB, and recently, recently, a single-sided 4.7 GB capacity DVD-R medium has begun to be supplied to the market. Yes. The DVD-R medium also employs a laminated structure in which cyanine dyes, azo dyes, etc. are used for the recording layer and a reflective layer is provided, and has a disc structure in which two 0.6 mm thick substrates are bonded together. It is said. At present, the development of a medium that supports high-speed recording is being actively promoted for an optical disc having good recording characteristics suitable for this capacity.

  Furthermore, it is expected that higher density recording will be required in the future, and the amount of information is expected to reach 15-30 GB per disc. It is inevitable to use a laser having a shorter wavelength as a means for realizing the recording density. Accordingly, a dye having good recording characteristics in the wavelength range of 300 nm to 500 nm is desired as a recording dye to be used in future organic dye-based optical recording media.

  By the way, regarding a medium capable of recording with higher density than DVD-R using an organic dye as a recording layer, Patent Document 1 discloses that a laser having an oscillation wavelength of 680 nm or less is used and a recording capacity of 8 GB or more is achieved. is there. In the proposal of this document, large-capacity recording of 8 GB or more is achieved by converging a laser beam of 680 nm or less with an objective lens having a high numerical aperture of 0.7 or more through a light transmitting layer having a thickness of 10 to 177 μm. ing.

  On the other hand, recently, a 410 nm laser using a GaN-based material as a blue laser having an oscillation wavelength of 390 to 430 nm and a SHG laser having a wavelength of 425 nm using a combination of a semiconductor laser and an optical waveguide element have been developed. Development of blue semiconductor laser compatible dyes suitable for various lasers is currently underway.

  Furthermore, HDTV (high definition television) broadcasting with a higher density capacity of 15 GB or more on one side when a blue-violet GaN-based semiconductor laser with an oscillation wavelength of 400 to 410 nm was tested from the beginning of 1999 (Nichia Corporation). Studies have been started on a medium (hereinafter referred to as an HD-DVD medium) capable of recording a moving image for about two hours with a normal image quality. The HD-DVD medium having such a high-density capacity can be recorded for about 6 hours if the image quality is equivalent to that of the current broadcast, and is therefore attracting attention as a new recording medium replacing the home VTR.

  Under such circumstances, a unified standard “Blu-ray Disc” for next-generation high-density optical disks was formulated and announced by nine companies in Japan, Europe and Korea (February 19, 2002). According to this standard, a blue-violet laser and N.I. A. = 0.85 combined with a high aperture lens, video data of up to 27GB can be repeatedly recorded / reproduced on one side of a 12cm disc, and if a recorder of the same standard is used, HDTV video can be recorded on a single disc for over 2 hours. It becomes like this. This corresponds to a recording time of 13 hours or more in the case of current broadcast NTSC video data.

  Also, the disc thickness of the same standard is 1.2 mm, and the laser beam is focused on the recording film formed over the light transmission layer of about 100 μm. Three types of recording capacities of 23.3, 25, and 27 GB are available. Proposed. Further, prior to the aforementioned standard, a blue-violet laser and N.I. A. Mentioned the applicability of organic dyes to recording media using a high aperture lens of = 0.85.

  At present, as organic dye compounds that can be recorded with a blue laser of 400 nm to 500 nm, in addition to cyanine dye compounds and porphyrin dye compounds, polyene dye compounds, azo dye compounds, dicyanovinylphenyl dye compounds, coumarin compounds, Pyrimidine compound, naphthalocyanine compound, hetero 5-membered ring compound, bisazole compound, aminopyridine compound, bispyridinium compound, oxonol compound, styryl compound, aminobutadiene compound, metal chelate compound, quinone compound or quinodimethane compound, hydrazone compound, carbostyryl compound Alternatively, naphthyridine compounds, condensed heterocyclic compounds, stilbene compounds, and the like have been proposed.

  In addition, an optical recording medium described in Patent Document 2 in which two layers of a recording layer mainly composed of a porphyrin-based dye or a cyanine-based dye and a metal reflective layer mainly composed of silver are formed as an organic dye for forming a recording layer, In addition, as a device devised in the medium configuration, it has a blue laser-sensitive dye layer containing a cyanine dye sensitive to a blue laser and a red laser-sensitive dye layer, which enables recording in a two-wavelength region. And an optical recording medium described in Patent Document 4 using an indigoid dye compound capable of recording in a two-wavelength region by mixing two dyes, a blue laser dye and a red laser dye In addition, an optical recording medium described in Patent Document 5 using a cyanoethene dye, an optical recording medium described in Patent Document 6 using a squarylium dye compound, and the like have been proposed.

  In addition, as an example of recording an organic dye film in a blue region of 400 to 500 nm, as a side chain, a molecular compound and a polymer coordinated to the central metal of a porphyrin compound or a molecular structure coordinated to the central metal are used. By mixing with molecules, the Soret band of the porphyrin compound is shifted to the longer wavelength side to support the 488 nm Ar laser, and film formation by spin coating is enabled to reduce manufacturing costs. Proposals have been made (Patent Documents 7 to 8). In addition, the polyene dye compounds (Patent Documents 9 to 10) have poor light stability according to the study by the present inventors, and it is necessary to devise a quencher blend or the like for practical use.

On the other hand, examples of an optical recording medium using a metal complex compound include an optical recording medium using a metal chelate dye (Patent Document 11) and an optical recording medium using a metal-containing azaoxonol-based dye compound (Patent Document 12). Can be mentioned.
JP-A-10-302310 Japanese Patent Laid-Open No. 11-53758 Japanese Patent Laid-Open No. 11-203729 Japanese Patent Laid-Open No. 11-78239 JP-A-11-105423 Japanese Patent Laid-Open No. 11-110815 JP-A-7-304256 JP-A-7-304257 JP-A-4-78576 Japanese Patent Laid-Open No. 4-89279 JP 2002-36727 A JP 2002-46354 A

  As a recent situation, a blue-violet semiconductor laser having a wavelength of 400 nm to 410 nm has been put to practical use, and a large capacity write once optical recording medium using the laser has been actively developed. Development of a dye having high-speed recording characteristics is desired.

  However, the actual situation is that the above-described optical recording medium is not sufficiently adapted to laser light having a wavelength of 400 nm to 410 nm. That is, in the medium using the above-mentioned organic dye, there is a problem that the signal cannot be read satisfactorily because the ratio of carrier wave to noise (C / N) is not always a good value for reproducing the recorded signal. We found out. There is an urgent need to overcome this problem and develop an optical recording medium capable of high-density recording / reproduction with a laser beam having a wavelength of 400 nm to 410 nm.

The inventors of the present invention have studied the recording material suitable for the optical recording medium, and have obtained the following two findings.
(1) Since a large-capacity optical recording medium uses laser light of 300 to 500 nm for recording writing and reading, control of the extinction coefficient, refractive index, and reflectance in the vicinity of the laser wavelength is important as a recording material.
(2) As described above, a large-capacity optical recording medium using the laser has been actively developed, and the development of a dye having particularly high light resistance and good high-speed recording characteristics is desired. The above-mentioned dye compound as a recording material capable of recording / reproducing with respect to laser light in the wavelength region has not yet obtained sufficient characteristics, and there is room for improvement. In addition, when producing a medium by a coating method such as a spin coating method, which is easy to form a recording film, one of the advantageous properties is that it has high solubility in a coating solvent. It is necessary to.

  In general, in order to increase the recording capacity, it is necessary to perform recording at a higher density. Therefore, the numerical aperture of the objective lens for focusing the optical beam used for recording is increased, and the laser wavelength of the optical system is further increased. It is essential to shorten the wavelength. However, the minimum optical beam diameter is determined by the diffraction limit of the narrowed optical beam. Further, in order to have high-speed recording characteristics, it is important that the laser power during recording is as small as possible. That is, it is important to develop a highly sensitive dye that can form good recording pits with less laser energy.

  By the way, since the recording is performed when the beam intensity exceeds a certain threshold, a recording pit smaller than the narrowed beam spot can be obtained as shown in FIG. The circumference of this recording pit corresponds to the base of the intensity peak of the beam, but in the present situation where the wavelength is further shortened, the photochemical reaction of the recording layer is promoted also around the recording pit, especially in the wavelength region of the blue-violet laser described above. Since the wavelength range is such that the photochemical reaction of the organic compound easily occurs, there is a problem that the pit edge is deteriorated during recording and the signal characteristics are deteriorated. That is, as shown in FIG. 1B, the recording information that must be formed corresponding to the rectangular wave [solid line in FIG. 1B] has a broad waveform due to deterioration of the pit edge [FIG. Of the broken line]. Further, when reproduction is performed at the same blue-violet laser wavelength as that during recording, there is a problem that the photoreaction is promoted even by weak light irradiation such as reproduction light, and the deterioration proceeds with each reproduction. No. 304256 and Japanese Patent Application Laid-Open No. 7-304257 also have to take measures to make the recording light and the reproduction light have different wavelengths, substantially longer than the recording light, and as a result, sufficient The current situation is that the demand for high density cannot be met. Also, differentiating the recording wavelength and the reproducing light wavelength requires that the recording device and the reproducing device be prepared separately or that one device be provided with two optical systems and its control system. Applications will be limited, the size of the device will increase, and costs will increase, resulting in poor versatility. Conventionally, in an optical recording medium such as a CD-R, recording is turned on / off with a clear thermal threshold in terms of physical properties such as the melting point, sublimation point, phase transition point or thermal decomposition point of the organic dye film. Contrary to what has been achieved, the presence of the photodegradation mode by blue-violet laser excitation obscures this contrast, especially in high-density recording systems where fine recording pits smaller than the optical beam must be formed. There was a concern of degrading quality.

Here, as an example of recording an organic dye film in a visible light region having a wavelength of 400 to 700 nm, an optical storage medium capable of recording / erasing using a perylene compound described in JP-A-2002-501497 can be mentioned. Japanese Patent Application Laid-Open No. 10-6645 also describes a medium using a similar perylene compound for a recording layer using a laser beam having a wavelength of 620 to 690 nm. However, it has been found that these compounds are still not sufficient in terms of light stability and signal characteristics even when recording with a blue-violet laser having a wavelength of 400 to 410 nm.

  An object of the present invention is a recording suitable for ultra-high density recording capable of good recording and reproduction with a laser beam having a wavelength of 300 nm to 900 nm, particularly a blue-violet laser beam selected from a wavelength range of 400 nm to 410 nm. It is to provide an optical recording medium having a layer. Another object of the present invention is to provide a novel compound that can be suitably used for the optical recording medium.

As a result of intensive studies to solve the above problems, the present inventors have completed the present invention. That is, the present invention

Therefore, it is possible to provide an optical recording medium that can perform the above.

  The present invention relates to an optical recording medium comprising the recording layer of the optical recording medium containing the triazine compound according to the present invention, and relates to an optical recording medium having a wavelength of 300 nm to 900 nm, particularly a wavelength of 390 nm to 430 nm, and further a wavelength of 400 nm to 410 nm. The present invention relates to a novel optical recording medium and a novel triazine compound that can be recorded and reproduced by a laser beam selected from the following.

  The optical recording medium according to the present invention refers to an optical recording medium that can record and reproduce information. However, here, as an example, the optical recording medium of the present invention having a recording layer and a reflective layer on a substrate will be described. In the following description, the optical recording medium is an optical disc, which has, for example, a guide groove on a support substrate, and a recording layer mainly composed of a reflective film and an organic dye on the guide groove. A medium for recording and reproducing signals by irradiating a 900 nm laser beam will be described. However, the optical recording medium of the present invention is not limited to such a shape and configuration, and various other types such as a card shape, a sheet shape, etc. The present invention can also be applied to recording / reproduction with a laser having a shorter wavelength, which does not have a reflective layer, and will be developed in the future.

  The optical recording medium of the present invention has, for example, a four-layer structure in which a substrate 1, a recording layer 2, a reflective layer 3, and a protective layer 4 are sequentially laminated as shown in FIG. It has such a bonding structure. That is, the recording layer 2 is formed on the substrate 1, the reflective layer 3 is provided in close contact with the recording layer 2, and the protective layer 4 is further bonded thereto with the adhesive layer 5 interposed therebetween. However, another layer may be provided below or on the recording layer 2, and another layer may be provided on the reflective layer 3. Further, as shown in FIG. 4, a structure in which the substrate 1, the reflective layer 3, the recording layer 2, and the protective layer 4 are laminated in this order and recording / reproducing from the protective layer side may be employed. Further, as described in JP-A-10-326435, the thickness of the light transmission layer is such that the numerical aperture of the optical system is N.P. A. The medium structure may be defined by the laser wavelength λ. The optical recording medium of the present invention may have a structure having two or more recording layers as described in JP-A No. 11-203729 as required.

  Further, as an example in which the present invention is applied to an optical disc, a substrate 11, a recording layer 12, a reflective layer 13, and a protective layer 14 are laminated in this order as shown in FIG. 5, and further on the protective layer 14 also serving as an adhesive layer. The thing which bonded the dummy board | substrate 15 is mentioned. Of course, a configuration without the substrate 15 may be used, between the substrate 11 and the recording layer 12, between the recording layer 12 and the reflective layer 13, between the reflective layer 13 and the protective layer 14, and between the protective layer 14 and the dummy substrate 15. Other layers may exist between the two. In the optical disk of FIG. 5, recording / reproduction is performed from the substrate 11 side.

  As another embodiment, a reflection layer 13 ′ and an organic dye are arranged on a support substrate 11 ′ having a guide groove as shown in FIG. 6, for example, as disclosed in JP-A-10-302310. A recording layer 12 ′ as a main component is formed in this order, and a light transmission layer 15 ′ is formed on the recording layer 12 ′ via a transparent protective layer 14 ′ optionally formed as necessary. Recording and reproduction of information is performed from the light transmission layer 15 ′ side. Conversely, a guide groove may be formed on the light transmitting layer 15 ′ side, and a transparent protective layer 14 ′, a recording layer 12 ′, and a reflective layer 13 ′ may be laminated thereon and bonded to the support substrate 11 ′. . The light transmission layer 15 'may also serve as the transparent protective layer 14'.

  Alternatively, as still another embodiment, a configuration disclosed in Japanese Patent Application Laid-Open No. 2002-175645, for example, as shown in FIG. 7, a recording mainly composed of an organic dye on a support substrate 21 on which guide grooves are formed. A layer 22 is formed, and a dielectric layer 40 is formed by sequentially laminating a nitride layer 23 and an oxide layer 24 on the recording layer 22. Further, an adhesive is applied on the dielectric layer 40 as necessary. Thus, the light transmission layer 25 is formed, and information recording and reproduction are performed from the light transmission layer 25 side. On the contrary, a guide groove is formed on the light transmission layer 25 side, and a dielectric layer 40 and a recording layer 22 formed by sequentially stacking an oxide layer 24 and a nitride layer 23 are stacked thereon, It is good also as a structure bonded together. As described above, the present invention can be applied to an optical recording medium capable of obtaining a suitable initial reflectance by forming a dielectric layer on an information recording layer without using a reflective layer and obtaining an optical enhancement effect due to multiple interference. Compounds can be applied.

  In the present invention, a recording layer is provided on a substrate. The recording layer of the present invention has at least one triazine compound according to the present invention, particularly a compound represented by the general formulas (1) to (3) as a recording dye. It contains seeds. Here, the recording dye is a dye capable of forming a portion in which the reflectance is changed by a change in the recording layer or a change in shape (pit formation), etc. induced by laser light irradiation and sublimation. is there. Further, by using the compound according to the present invention, an optical recording medium capable of obtaining a sufficient degree of modulation can be obtained. The optical recording medium of the present invention is capable of recording / reproducing with respect to a recording laser wavelength selected from a range of 300 nm to 900 nm, among which a wavelength of 390 nm to 430 nm, and further a wavelength of 400 nm to 410 nm is selected. This is an optical recording medium that can obtain good signal characteristics with respect to the recording laser wavelength and the reproduction laser wavelength.

Since the triazine compound according to the present invention can arbitrarily select an absorption coefficient and an absorption wavelength by selecting a substituent, the optical constant necessary for the recording layer can be satisfied at the wavelength of the laser beam. Further, a recording film having excellent film forming stability can be obtained by selecting a substituent. Furthermore, it is a very useful organic dye having high stability to light and excellent reproduction light stability.
The present invention will be described in further detail below.
