Title:
RECORDING LAYER FOR OPTICAL INFORMATION RECORDING MEDIUM, OPTICAL INFORMATION RECORDING MEDIUM, AND SPUTTERING TARGET FOR OPTICAL INFORMATION RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2007/046390
Kind Code:
A1
Abstract:
This invention provides a recording layer for an optical information recording medium
that is excellent, for example, in initial reflectance and recording mark moldability,
as well as in durability under a high temperature and high humidity environment,
and can be satisfactorily applied to advanced optical disks using a bluish-violet
laser. The recording layer for an optical information recording medium is a recording
layer in which recording marks are recorded by laser beam irradiation. The recording
layer is formed of an Sn-base alloy containing not less than 1.0% and not more than
15% in total of at least one element selected from the group consisting of Nd, Gd
and La.
