ABSTRACT:
A high-density magneto-optical recording medium having excellent jitter properties is provided. A pattern-dependent shift of the length of a recorded mark does not occur even when a minute mark has increased sensitivity to a recording magnetic field. A magneto-optical recording medium has at least a displacement layer, a memory layer, and an auxiliary memory layer. A mark with a length up to the diffraction-limit of the optical system is recorded and read out. The magneto-optical recording medium includes an in-plane magnetization-inducing layer principally made of cobalt on the auxiliary memory layer.
