去残り防止回路。 A recording/reproducing magnetic head and an erasing head are incorporated in the same case, and the magnetic head is configured to be displaced from a non-operating position away from the magnetic tape to an operating position in contact with the magnetic tape during recording and reproducing operations. In a tape recorder, a power switch that is closed during recording and playback operations and supplies operating current to the motor and the tape recorder circuit, and an erase switch that is closed during recording operations and supplies erasing current to the erase head. A circuit for preventing residual erasing of a tape recorder, characterized in that the erasing switch supplies the erasing current independently of the power switch and before the electric head comes into contact with the magnetic tape.
