摘要：An optical information recording medium which makes it possible to reduce thenoise level, improve the C/N ratio and store record data for a long time period. Anoptical information recording medium has a recording layer formed on a substrate, for
having a laser beam irradiated thereto for recording and reproduction of record data.The recording layer includes a first sub-recording film and a second sub-recording film.The first sub-recording film is formed of a first material containing Si as the maincomponent. The second sub-recording film is formed of a second material containing Alas the main component and having Ti added thereto, and disposed in the vicinity of thefirst recording film. The laser beam is irradiated to the recording layer via a lighttransmitting layer formed in a manner covering the recording layer side.
