ABSTRACT:
An address on a magnetic tape to be searched and a current address of the magnetic tape which is read by playing back the tape are supplied to first arithmetic operation means to produce a signal indicative of the tape length to be fast moved and a signal indicative of the direction of the fast tape movement so that the tape is fast moved in the selected direction in response to the derived direction signal. Second arithmetic operation means watches address pitch signals produced during the fast tape movement and the tape length to be fast moved derived from the first arithmetic operation means, to release the fast tape movement when the predetermined length of tape has been fast moved.
