OPTICAL RECORDING MEDIUM AND VISIBLE INFORMATION RECORDING METHOD

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.
