ABSTRACT:
A test burst signal is overwritten from a write end position over a connecting region determined by positional deviation between a read head and a write head and a peripheral speed of a disk. Since, therefore, the overwritten signal portion is overlapped on the test burst signal written at a write start point, it is possible to reduce a width of the connecting region to thereby reduce a test inhibit region.
