装置。 A first tape deck having at least a playback function, fast forwarding and rewinding functions, and a second tape deck having at least a recording function and fast forwarding and rewinding functions. In a magnetic tape device configured to record on a tape and configured to switch the rotational speed of a motor for driving each of the magnetic tapes to a low speed or a high speed, a leader tape at an end of the magnetic tape is attached to each tape deck. A magnetic tape device comprising a detection means for detecting a leader tape, and a means for setting the rotation of the motor to a low rotation speed in response to detection of a leader tape by the detection means when the motor is rotating at a high speed. .
