METHOD OF REPRODUCING MAGNETO-OPTICAL RECORDING MEDIUM, MAGNETO-OPTICAL RECORDING MEDIUM AND MAGNETO-OPTICAL RECORDING AND REPRODUCING DEVICE

摘要

PROBLEM TO BE SOLVED: To reproduce micromagnetic domains at a high signal-to-noise ratio and low reproduction stokes by performing transfer and enlargement of the micromagnetic domains and erasure of the transfer magnetic domains. SOLUTION: Reproducing magnetic fields are alternated by a magnetic field generator in reproduction using exchange bonded multilayered films. The reproduction signal-to-noise ratio of the micromagnetic domains is greatly improved and the crosstalks of reproduction are drastically ameliorated.
