Abstract
Disclosed is a recording member which comprises a substrate and a recording layer containing at least selenium and at least one element selected from the group consisting of tellurium and bismuth, wherein the selenium content is higher in the vicinity of the surface of the recording layer and/or in the vicinity of the interface between the recording layer and the substrate than the average selenium content in other portions. By virtue of the presence of this high selenium content portion, the oxidation resistance and water resistance are improved, and a recording member having stable characteristics can be obtained.
