    摘要: 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/s to the light, the time required for the reflectivity to change and reach a saturated level, is at most 130% of said pulse length.

    摘要: By use of a substrate which can be stably formed and has a relatively small groove depth, a very high density optical recording medium having good recording/reading characteristics is provided. In an optical recording medium of a surface incidence type, in which a reflective layer, a recording layer containing a dye as a main component and a cover layer are sequentially formed on a substrate having guide grooves formed therein, a guide groove part on a far side from a plane of incidence of a recording/reading light beam on the cover layer is set as a recording groove part, and reflected light intensity in a recorded pit portion formed in the recording groove part is increased by a phase shift and is set higher than reflected light intensity in unrecorded.
