Abstract
Magneto-optical (MO) disks using CoPtRe ternary alloy films have been investigated as a novel recording material for a blue laser recording. For various types of disk structure, the Kerr rotation, the Kerr ellipticity, and the figure of merit were calculated and an optimum structure was estimated. Magneto-optical recordings were made on a CoPtRe MO disk at wavelengths of 830 and 530 nm. The recording properties were almost equivalent to those for Co/Pt multilayers.
