Optical recording medium and optical recording method |
摘要 |
<p>An optical recording medium having a recording layer containing an organic colorant as the main component, whereby recording is carried out by changing the reflectivity by irradiation of a laser beam for recording having a wavelength of at most 700 nm, wherein when a light having substantially the same wavelength as the laser beam for recording and having an intensity selected from a range of from 1 to 4.5 mW and a pulse length of about 382 nsec, is irradiated while moving a portion to be irradiated of the medium at a relative velocity of 0.3 m/sec to the light, the time required for the reflectivity to change and reach a saturated level, is at most 130% of said pulse length. <IMAGE></p> |
