ABSTRACT:
An apparatus and formatting method formats a disk without using an index pulse generated by hardware for every disk rotation. A last data block gap and a track gap which are longer than a standard track gap length are first written. Even if there is a fluctuation in rotation cycle time during formatting, a last sector of each track is written over a beginning of the track gap. When writing to a last sector is complete, formatting of a track is complete. When a head is stably positioned at a track to be formatted, formatting of the track is started.
