ことによって検出される。Generally, optical disks can store high-density information using small (eg, about 1 μm) optically detectable bits formed in a thin film recording layer on a substrate in the form of spiral or circular tracks. To write information on such a disk, a focused laser beam is scanned over the surface of the Rade-sensitive layer, and bits are formed only on the surface irradiated with the laser beam. Formed in the form of This sensitive layer can absorb laser energy to form an optically detectable bit. For example, in the heat mode recording method, the recording layer absorbs laser energy and the irradiated area is locally heated, causing physical changes such as melting, evaporation, or aggregation, resulting in optical differences (e.g. reflectance, etc.) between the recording layer and the non-irradiated area. absorption rate, etc.) and reading it.
この様な光記録媒体としてこれまでアルミニウム蒸着膜
などの金属薄膜、ビスマス薄膜、テルル系薄膜やカルコ
ダナイド系非晶質プラス膜などの無機物質が提案されて
いる。As such optical recording media, inorganic materials such as metal thin films such as aluminum vapor-deposited films, bismuth thin films, tellurium-based thin films, and chalcodanide-based amorphous plus films have been proposed.
これらは、蒸着法、スバ、り法などにより薄膜が得られ
、近赤外域でも光吸収を有するため半導体レーデが使用
できるという長所があるが、反面反射率が犬きく、シか
も熱伝導率が大きく、比熱も大きいという欠点がある。These materials have the advantage of being able to be formed into thin films by vapor deposition, coating, and lithography methods, and can be used with semiconductor radars because they absorb light even in the near-infrared region. It has the disadvantage of being large and having a large specific heat.

果、記録装置が大型かつ高価になると云う欠点がある。In particular, if the reflectance is high, the energy of the laser beam cannot be used effectively, so the optical energy required for recording increases, and a high-output radar light source is required. As a result, the disadvantage is that the recording apparatus becomes large and expensive.

る成膜性や反射率、吸収率の低下という問題が生じる。Furthermore, thin films of tellurium, bismuth, selenium, etc. have the disadvantage of being toxic. For this reason, in recent years it has become possible to select the absorbency, with a high absorption rate and low heat conduction.
In addition, research proposals have been made on optical memory media using dye thin films as recording layers because of their high productivity and low toxicity. Typical dyes include cyanine dyes (JP 58-112790), anthraquinone dyes (JP 58-224448), naphthoquinone dyes (JP 58-224793), and phthalocyanine dyes (JP 58-224793).
JP-A-6O-48396), etc., and is an optical recording medium in which a compound consisting of these alone or in combination with a self-oxidizing resin is formed on a substrate by a spinner coating dipping method, a plasma method, a vacuum evaporation method, etc. . This dye thin film system has the above-mentioned advantages; in particular, the cyanine dye can structurally have an absorption wavelength in the near infrared region, and also has advantages such as low solubility in solvents and low melting point. Many studies have been carried out since then. On the other hand, it has been said that there are problems with light deterioration, instability with heat, humidity deterioration, etc., long-term storage stability, playback stability (stability against readout light), etc., and there are various problems regarding these problems. Improvement plans have been proposed. Specifically, a protective film is provided on the recording layer (Japanese Unexamined Patent Publication No. 55-22961.57-66541), and a substance that prevents discoloration due to oxygen is mixed (Japanese Unexamined Patent Publication No. 59-598).
5705), forming a recording layer by adding a metal complex that absorbs light in a long wavelength region (Japanese Patent Laid-Open No. 59-215892)
) etc. have been proposed. However, these proposals do not sufficiently solve the problem, and furthermore, problems arise in that the additives cause a decrease in film formability, reflectance, and absorbance.

It is known that solvent solubility decreases with an increase in , and that solubility changes depending on the type of heterocycle at both ends and the type of substituent. Regarding heat and light stability, as the number of methyl/chains increases, it becomes less stable to heat and light, and oxidative deterioration becomes more likely to occur, and the stability to heat and light differs depending on the type of heterocycle. It has been known.
