ABSTRACT:
A head position controlling device adjusts the position of the head so as to maintain a prescribed relative positional relationship between the magnetic tape and the head. This head position controlling device includes a moving mechanism which moves the head in the lateral direction of the magnetic tape and a tracking circuit for reproduction which controls the head moving mechanism so as to cause during reproduction the head to follow a plurality of the recorded tracks formed on the magnetic tape. This head position controlling device further includes a tape position detecting device which detects the position variations of the magnetic tape relative to the head without making contact with the tape, and a tracking circuit for recording which controls the head moving mechanism in such a way as to cause the head to follow the lateral motion of the tape in order to maintain the running position of the magnetic tape on the head to be fixed, corresponding to the position variations of the magnetic tape detected by the tape position detecting device during recording.
