Abstract
A sector address is obtained even when a playback signal is missed by incrementing the number of interpolations n when determined that error correction of read-out data is not possible, and incrementing and storing in a buffer 'address' the contents of a work area B when the number of interpolations n is less than a preset value 'Max'. When the interpolation address calculation process has been repeated the prescribed number of times 'Max' an emergency process is carried out.
