MAGNETIC RECORDING MEDIUM FOR LONGITUDINAL RECORDING

摘要

PROBLEM TO BE SOLVED: To provide a magnetic recording medium for high-density longitudinal recording having excellent characteristics against thermal fluctuation in magnetization. SOLUTION: The magnetic recording medium for longitudinal magnetic recording has a single-layer or multilayer nonmagnetic metal base layer, at least a pair of a metal magnetic stabilizing layer and a nonmagnetic metal spacer layer formed on the stabilizing layer, and a single-layer or multilayer metal magnetic layer successively formed on a nonmagnetic substrate. The metal magnetic stabilizing layer and the metal magnetic layer are antiferromagnetically coupled.
