摘要： A magneto-optical recording medium formed to record an information signal on both of lands and grooves provides a capability of reproducing an excellent signal with a small magnitude of crosstalk even by narrowing a track interval more. In the magneto-optical recording medium, an optical depth d of each groove is in the range of (1/12+n/2).lambda..ltoreq.d.ltoreq.(1/6+n/2).lambda. or {-1/6+(n+1)/2}.lambda..ltoreq.d.ltoreq.{-1/12+(n+1)/2}.lambda., where .lambda. is a wavelength of a light beam to be applied onto the recording medium and n is an integer of 0 or more. When reproducing the information signal from the medium, a phase difference is given to the return light from the medium before detecting the return light.

摘要： A high density magnetooptical recording and playback method is disclosed. The magnetooptical recording medium comprises a recording hold magnetic layer and a playback magnetic layer magnetically coupled with each other. Prior to the playback operation, the playback magnetic layer is initialized by an external magnetic field. A laser light is irradiated to locally heat the medium and cause transfer of magnetization in the recording hold magnetic layer to the playback magnetic layer. The signal is read out by the interaction of the laser light and the transferred magnetization.
