Abstract

PURPOSE:To obtain stable reproduced data by controlling the azimuth of a reproducing head by a signal which corresponds to the time difference between synchronizing signals separated from reproduced data of two specific tracks among plural tracks. CONSTITUTION:Synchronizing signals in data reproduced by reproducing heads 1-1-1-n are separated by tracks through synchronizing signal separating circuits 2-1-2-n, and a synchronizing-signal time-difference detecting circuit 3 outputs a control signal, which corresponds to the time difference between the two inputs of specific tracks[1st and (n)th tracks], to a detecting circuit 3, which controls a motor 13 to control the azimuths of the reproducing heads. Thus, stable reproduced data is obtained.
