Abstract

PURPOSE: To reduce tape position detectors in number and also to simplify a control circuit by controlling the drive of a capstan, file reel and machine reel so that the leading position of a tape in a tape buffer will be within a fixed range.
CONSTITUTION: Once supplied with external REV signal 38 for slow reversing, capstan 6 moves tape T in the D direction and the tape loop of tape buffer 3 is controlled centering on the detection position of tape position detector 8 while file reel 1 rewinds the tape uniformly. The tape in buffer 4, on the other hand, is controlled centering on the detection position of position detector 9 and machine reel 2 feeds the tape out uniformly. Once RWD signal 39 for fast reversing is generated at an appropriate time, capstan controller 36 operates corresponding to signal 42 of detector 9 to control capstan motor 62 via signal 44, thereby positioning the tape of buffer 4 at the detection position of detector 9. In this state, the tape speed can be determined by the mutual relation between reels 1 and 2.
