ABSTRACT:
Disclosed is a method for recording and reproducing sector control information to and from a novel magneto-optical disk to which the so-called erasure type data reproduction method or data-embossed type reproduction method applies. On the magneto-optical disk, sector control information is recorded onto a sector control information recording region at a track recording density lower than that of a data recording region. When data is recorded on the disk at a high track density, the sector control information is recorded in such a manner that the information will not exist on adjacent tracks along the same radials of the disk.
