生装置。 a magnetic head having a plurality of cores and capable of reproducing at least signals recorded on a magnetic tape; an erasing head for erasing signals recorded on the magnetic tape; and a drive means for driving the erasing head in the tilting direction of the magnetic tape based on a signal reproduced from at least one of the plurality of cores of the magnetic head. A magnetic recording and reproducing device that drives a magnetic tape in the width direction and performs tracking control, which is provided with a recording and reproducing switching means and a tape speed switching means, and when the recording state is switched by the recording and reproducing switching means. A constant offset voltage is applied to the driving means, a reference voltage (when there is no tracking error) is applied to the driving means during the reproduction state, and the offset voltage and the reference voltage are applied to the driving means in response to switching of the tape speed switching means. A magnetic recording/reproducing device characterized by being configured to change voltage.
