摘要:
A heat mode recordable, optical recording medium comprising: a transparent substrate; a recording layer containing a dye; and a reflective layer, wherein the recording layer comprises an organic dye, and the medium has an optimum recording power of at least 25 mW when recorded at a linear velocity v (m/sec) with a laser beam having a wavelength of 600 to 700 nm, the optimum recording power being defined as a recording power (Po) at which a jitter in recording 8/16 modulation signals is lowest and being represented by equation: Po=P1×{square root}{square root over ((v/3.5))}˜1.5P1×{square root}{square root over ((v/3.5))}in which P1 is an optimum recording power in recording at a linear velocity of 3.5 (m/sec).

摘要:
The present invention relates to an optical recording medium comprising a visible information recording layer on a support. The visible information recording layer comprises a given dye. The optical recording medium may further comprise a recording layer capable of recording and/or reproducing information by irradiation of a laser beam. The visible information is recorded by using the same laser bean as that used in recording information on the recording layer.
摘要:
The present invention relates to an optical recording medium comprising a visible information recording layer comprising a dye denoted by the following general formula (I) on a support. In general formula (I), A denotes a substituted or unsubstituted heterocyclic group, substituted aliphatic group, or substituted or unsubstituted carbon ring group, and B denotes a substituted or unsubstituted heterocyclic group or a substituted or unsubstituted aryl group. The optical recording medium may further comprise a recording layer capable of recording and/or reproducing information by irradiation of a laser beam. The present invention further relates to a method of recording visible information on the visible information recording layer of the optical recording medium, wherein the visible information is recorded by using the same laser bean as that used in recording on the above recording layer.

摘要:
An optical recording medium has a constitution wherein a visible information recording medium section and an information recording medium section are bonded through a bonding layer. The visible information recording medium section has a constitution wherein a visible information recording layer, a first reflection layer and a first protection layer are stacked on a first substrate. The information recording medium section has a constitution wherein an information recording layer, a second reflection layer and a second protection layer are stacked on a second substrate having a pregroove formed on the surface. The visible information recording layer contains at least one dye compound among a yellow dye compound, magenta dye compound and a cyan dye compound.
