たことを特徴とする磁気記録再生装置。 In a magnetic recording/reproducing device in which a rotating cylinder is provided with an erasing head and the erasing head erases a recorded track before the recording/reproducing head, an erasing operation control signal is converted into an optical signal at a predetermined position near the rotating cylinder. It has a photoelectric conversion unit that converts and outputs the signal, and is further provided with an oscillation circuit that creates an erasure signal in a rotating cylinder, and a switching circuit that receives the optical signal and controls the output signal of the oscillation circuit. A magnetic recording and reproducing device.
