Abstract

PURPOSE:To exactly execute after-recording by counting a reproducing clock or its corresponding clock, and correcting a numerical value, based on actual address information as a reference while calculating a numerical value corresponding to a head position on a track. CONSTITUTION:A reproducing clock or its corresponding clock (reference clock, etc.) is counted by calculating means 14, 16, 18 and 20, and while calculating a numerical value corresponding to a head position on a track, the numerical value is corrected, based on actual address information as a reference, by a correcting means 10. Accordingly, the numerical value corresponding exactly to the head position is obtained, and from this numerical value, it is detected exactly by a detecting means 22 that the head position on the track has reached a prescribed position. In such a way, after-recording can be executed exactly.
