Recording medium and recording-reproduction system provided with the recording medium

摘要

A recording medium comprises a first layer prepared from a material of perpendicular anisotropy, a second layer prepared from a compound of noncrystalline rare earth metal-3d transition metal and deposited on said first layer, and a transparent protective layer and mounted on said second layer. Data is magnetically recorded on the recording medium and the recorded data is optically read by utilizing the magneto-optics effects.
