ABSTRACT:
The present invention provides a cleaning disk and a magneto-optical disk drive apparatus being simple in structure, adaptable to cleaning disks having various specifications, low in power consumption, low in electromagnetic noise, and preventing damage to the magnetic head and the optical head; the cleaning disk comprises a magneto-optical disk having an information layer, and a head-cleaning member, provided on the magneto-optical disk, for cleaning the magnetic head of the magneto-optical disk drive apparatus, wherein information regarding a magnetic head cleaning condition for setting the operation condition of the magneto-optical disk drive apparatus during cleaning of the magnetic head has been recorded in advance on the information layer of the magneto-optical disk. The magneto-optical disk drive apparatus reads the information regarding the magnetic head cleaning condition so as to set the operation condition properly.
