摘要：
There are provided a magneto-optical disk, a super-resolution magneto-optical disk and a domain wall moving magneto-optical disk whose cross-talk, cross-write and cross-erasure are suppressed and whose recording density is improved. A recording magnetic layer formed on a land is shut off magnetically from the recording magnetic layer formed on a groove and thermal diffusion in the track direction is suppressed, by selectively oxidizing a magnetic layer formed on a side wall between the land and the groove.
