Abstract

PURPOSE:To improve the quality of a signal to be reproduced by detecting the scanning state of a recording/reproducing means and supplying a reproducing signal to a storage means only for a period of detecting the regular scanning over a recording unit area. CONSTITUTION:When an automatic track finding signal is read out by magnetic heads 3 and 4, an ATF signal level comparator circuit 10 calculates its comparison with a predetermined reference value to be outputted, while an error voltage generating circuit 11 feeds an error voltage an converted from misalignment of the scanning state to a capstan motor driving circuit 12, so that a capstan motor 13 is controlled in its operation state. Then, a tracking control circuit 16 outputs a tracking signal G and a on-track signal C in reference to a tracking error signal B and a tape speed signal E, and an acoustic signal D is outputted from an interface circuit 14 during a period of the signal C at a high level, so as to be stored in a storage part 15.
