Abstract

PURPOSE: To automatically select the fast-forwarded and reproduced portions of a tape thereby to continuously effect the position control by recording the signals having a filtered band as control signals so that the control signals are selectively extracted during the reproduction through a filter.
CONSTITUTION: The magnetic tape, in which letter and correct signals are recorded together with audio signals by an oscillator having a frequency higher or lower than such a band of the audis signals as is allowed to pass through a filter, is reproduced, and the reproduced information is fed to a selection control circuit 27. If the sweitches 28 and 29 of the circuit 27 are connected with the correct sides LC and C, the set output of FF 322 by the correct signals having passed through a filter 302 is fed through a driver 28R to interchange a switch 281, and an FF 36 is set so that the tape speed is controlled by a motor control circuit 37 to reproduce the correct signals. If, under this condition, the letter signals are detected by a filter 303, the FF 36 is reset through an FF 323 to effect the fast forward. Likewise, the letter signals are selected so that the continuous position control is performed by the automatic selection of the fast-forward and reproducing portions.
