Magnetic recording apparatus.

摘要

A helical scan type video tape recording (VTR) has an editing function mode in which a new video signal can be inserted between a cut-in point and a cut-out point on a video signal previously recorded on a video tape (4). The VTR comprises a rotary head drum (1), a rotary video head (2A, 2B) secured to the drum (1) for recording video signals on the tape (4) in a plurality of skewed video tracks, a recording control circuit (10 to 14) for supplying a recording current of the new video signal to the head (2A, 2B) in response to a recording command signal (P), a rotary erase head (3A, 3B) secured to the drum (1) for erasing a video signal recorded on selected ones of the video tracks, the erase head (3A, 3B) being positioned to scan the tracks ahead of the video head (2A, 2B) by a predetermined interval, and an erasing control circuit (14 to 19) for supplying an erasing current, in response to the recording command signal (P), to the erase head (3A, 3B) during an editing interval of the editing function mode except for at least one of two intervals in which the erase head (3A, 3B) traces the tracks at the cut-in point and the cut-out point so that the erasing current does not leak to the adjacent track in advance of the cut-in point and to the adjacent track following the cut-out point.
