を解除することを特徴とする磁気記録再生装置。 A control circuit that drives the tape running mechanism to a fast forward state when the cassette half is attached to the device or when the plate is operated, a rotation detection circuit that detects the rotation of the reel stand and outputs an output pulse in accordance with the rotation, and the rotation detection circuit. a period comparison circuit that compares the period of the output pulse of the rotation detecting circuit with a predetermined slowest period in a fast forwarding state of the tape running mechanism, and determines whether the output pulse period of the rotation detection circuit is equal to the predetermined slowest period. When it falls below that,
A magnetic recording/reproducing device characterized in that the control circuit releases a fast forwarding state of a tape running mechanism.
