ク装置。 In a magnetic disk device that records and reproduces information using a magnetic head through a recording/reproducing circuit on a magnetic recording medium, the write gate is opened in response to a write start signal and an index signal, an erase operation is performed, and the write data gate is opened in response to the next index signal. A write circuit comprising a circuit combining D-type flip-flops to open the circuit and record data, and a mono multi-channel circuit for resetting all the combined D-type flip-flops by the third index signal. A magnetic disk device characterized by having a circuit network.
