Abstract

PURPOSE:To realize high-precision tracking control following up a track on which signals are recorded even in recording, by using one rotary head for recording and reproduction and the other for tracking control. CONSTITUTION:Arm 21 connected to base 25 fixed to a rotary drum through elastic support bodies 23 and 24 and the provided with permanent magnet 22 has a pair of recording head Hp and control head Hr of the same gap width arranged at an interval of fixed distance D. Recording contents of a track right before recording by head Hr are reproduced by Head Hp. When correct tracking of this reproduction output is carried out corresponding to known data on distance D, a tape speed, rotary drum rotation speed, etc., the reproduction output of head Hp is compared with a reference voltage preset corresponding to a fixed rate of the space part of the track to a gap part and driving coils 26 is controlled so as to make its difference constant, so that even if a pair of heads Hr and Hp would shift in position, high- precision tracking control can be performed in recording.
