Verfahren zur Aufzeichnung von Sektorkontrollinformation auf eine magneto-optischen Scheibe |
摘要 |
Disclosed is a method for recording and reproducing sector control information to and from a novel magneto-optical disk (31) to which the so-called erasure type data reproduction method or data-embossed type reproduction method applies. On the magneto-optical disk (31), sector control information is recorded onto a sector control information recording region (34) at a track recording density lower than that of a data recording region (33). When data is recorded on the disk (31) at a high track density, the sector control information is recorded in such a manner that the information will not exist on adjacent tracks (36) in the same rotating direction of the disk. <IMAGE> |
