ABSTRACT:
A light information recording medium is disclosed. The medium is comprised of a support which has transparency with respect to light. The support has coated thereon a light sensitive recording layer which contains SiO.sub.2 and In at the SiO.sub.2 content of 10 to 35 vol. % based on the total volume of SiO.sub.2 and In. The recording medium can be used for the recording and reading of the information recorded thereon by striking the medium with laser light from the support side. The recording medium can be used as an optical disk memory having excellent recording sensitivity with respect to laser light, long preservability and high resolving power as well and high S/N ratio.
