MAGNETIC RECORDING MEDIUM AND METHOD OF MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide a magnetic recording medium which can be manufactured at a substrate temperature of a level of room temperature, which realizes a high S/N ratio and high coercive force and which is suitable for high density recording and to provide a method for manufacturing it. SOLUTION: In the magnetic recording medium, a magnetic thin film consisting essentially of Co-Pt or Co-Pt-Cr and containing an oxide MxOy is formed on a substrate as a magnetic layer. The content of oxide MxOy is specified to be such as amount that the ratio of constituent element M which constitutes the oxide to the Co-Pt or Co-Pt-Cr is 4 atom % or more and 8 atom % or less and the thickness of the magnetic layer is 10 nm or more and 25 nm or less.
