ABSTRACT:
A magneto-optical disk inspecting apparatus in which n pairs of a write head and a read head, and an area of the magneto-optical disk to be inspected are divided into n zones, the respective n pairs being assigned to the respective n zones so that the respective read heads read the data written in the magneto-optical disk by the respective write heads, such that characteristics of the magneto-optical disk can be inspected. An inspection is conducted by n pairs of a write head and a read head assigned to n zones of the area of a magneto-optical disk to be inspected, such that the inspection time can be shortened.
