ABSTRACT OF THE DISCLOSURE A helical scan type video tape recorder having a special reproducing function is disclosed, wherein a rotary magnetic head is mounted on an electrically deflect- able bi-morph leaf so that a reproduced image is obtained without guard-band noise at any special reproducing modes. A pair of counters are provided in order to decide a bias potential for the bi-morph leaf so that the rotary magnetic head nay start to scan just on a video track from the beginning. Control track pulses reproduced from a video tape and pulse signals generated in association with the movement of the video tape are used for determining a position of the video track relative to the rotary magnetic head.
