Abstract
A recording and reproducing apparatus for a disk-type recording medium including an erase head and a record head which are arranged with a certain rotational angular spacing. The apparatus includes a controller for generating a first signal to operate the erase head and a second signal to operate the record head, and a timing adjusting circuit for delaying either one of the first and second signals to compensate for an error of the angular spacing.
