Abstract

PURPOSE: To enable after-recording which is free from a deviation in a track scanning direction by providing a means which sets a window signal for protecting an ATF (Automatic Track Finding) detection signal and controlling a means which generates a signal area decision signal by utilizing it.
CONSTITUTION: When a signal for tracking a track latter half part is detected in a window signal based upon the position of a signal for tracking a track former half part, the reference for the generation of a window signal for deciding a signal area is switched from a drum pulse generator (PG) to a tracking signal, and when operation based upon the tracking signals is performed and tracking signals at four positions detected between two tracks are all absent, the reference is switched to the drum PG. Consequently, wrong data are from being inputted and the after-recording which is free from the track deviation is enabled.
