Description of the Related Art Optical recording media used in this type of optical recording and reproducing apparatus are known to be composed of a substrate, a metal reflective layer, and a recording layer containing a dye. This optical recording medium is formed so that a laser beam incident on a recording layer containing a dye reaches a metal reflective layer and is reflected so that the reflected light can be easily detected. It is provided to compensate for the amount of reflected light that is insufficient with the recording layer alone.

因から、記録再生特性および保存安定性が低下するとい
う問題があつた。However, the presence of the metal reflective layer complicates the structure of the optical recording medium and causes an increase in cost. Therefore, by using an organic dye thin film as a recording layer with high reflectance, the above-mentioned drawbacks can be eliminated. In particular, when polymethine dyes, azulene dyes, cyanine dyes, pyrylium dyes, etc., which have large light absorption against laser light, are used as organic dye thin films, metallic luster (reflectance 1
0 to 50%) is obtained, resulting in an optical recording medium that is capable of laser recording and reflection readout. In particular, use of a semiconductor laser with an oscillation wavelength of 700 to 800 nm as a laser light source has the advantage that the device can be made smaller and lower in cost. However, organic dye thin films generally have a problem in that their recording/reproducing characteristics and storage stability deteriorate because of their tendency to change in substance when exposed to heat and light.

であった。In addition, in the above-mentioned recording method, optical recording media are recorded with a strong laser power using the same laser and reproduced with a weaker laser power than during recording, so it is necessary to have a clear threshold value for the laser power. be. However, compared to inorganic thin films, organic dye thin films have a clear threshold value as described above, and are susceptible to deterioration during reproduction.

, 20, 69 [Example 48] In the evaluation of Example 24 using the optical recording medium produced in Example 24, the recording laser power was varied from 0.5 mW to 7 m
The C/N ratio was measured by changing the temperature up to W, and the threshold value was investigated. The results are shown in FIG.

し再生時に劣化しやすいことを示している。The optical recording medium of Example 48 had a clear threshold value at which recording was not possible at a low laser power of 2 mW or less. On the other hand, in Comparative Example 3, recording was possible even at a low power of 2 mW or less, and the threshold value was not clear. This indicates that it is susceptible to deterioration during repeated playback.
