Abstract: PURPOSE:To protect a recording medium by driving temporarily the medium in the forward direction when the medium is driven in the reverse direction and driving the medium in the reverse direction if the medium speed is a steady speed but inhibiting driving in the reverse direction if the medium speed is abnormal. CONSTITUTION:When the medium is driven in the reverse direction, a capstan is rotated forward, and a timer 7 is operated, and a timer output 14 goes to the high level after a certain period. If the capstan speed is not a steady speed, a speed detection output 13 is kept low-level, and the output of an FF 8 is not changed, and a Q output 15 and a Q' output 16 are kept low-level and high-level respectively. At this time, the output of a gate 11 does not go to the high level, and signals 21 and 22 are in the low level still, and the capstan is not driven in the reverse direction after rotating forward only for the certain period set by the timer 7. Thus, recorded information and the medium are protected when the medium is stuck to a head because of adhesive matters.
