A blue laser-ready information recording medium improved in light stability and durability without impairment of record/playback characteristics is provided.
The information recording medium is an optical information recordingmediumhaving on a substrate a recording layer that permits recording of information by irradiation with laser light of 440 nm or below, and is a heat-mode information recording medium that has a recording layer containing a methine dye and an organic oxidant on a transparent disk-form substrate on which a pregroove having a track pitch of 0.2 to 0.5 µm is formed, and that on the pregroove-formed side of the substrate.
本发明提供了一种可用于蓝色激光的信息记录介质,该介质的光稳定性和耐用性得到了改善,且不会影响记录/回放特性。
该信息记录介质是一种光学信息记录介质,在基板上具有可通过 440 纳米或以下激光照射记录信息的记录层,并且是一种热模式信息记录介质,在透明盘形基板上具有含有
甲胺染料和有机
氧化剂的记录层,在该基板的预槽形成侧形成了轨道间距为 0.2 至 0.5 微米的预槽。
