Abstract
In an apparatus which employs rotary heads for recording a video signal and a Pulse Code Modulated signal in first and second areas along successive slant tracks on a magnetic tape scanned by the heads and for recording a subcode signal in a third area in each slant track between the respective first and second areas; a pulse generator provides a pulse signal indicating a rotational position of each rotary head, the beginning of the subcode signal recorded in the third area of each track is dependent on the pulse signal, the end of the Pulse Code Modulated signal recorded in the respective first area is detected, and an erasing code signal is supplied to the rotary head scanning the tape for recording in an area of the respective slant track extending from the detected end of the Pulse Code Modulated signal in the first area to the position at which the recorded subcode signal begins in the third area.
