Claims

[Claims for Utility Model Registration] A pair of magnetic heads facing each other on both sides of a magnetic disk, such that during reproduction, both sides of the magnetic disk face the same magnetic heads as those facing during recording. When all of the magnetic disks are set in the specified set state, an access signal is output, and during playback, the magnetic disk is placed in a non-specified set state in which both sides of the magnetic disk face a different magnetic head from the magnetic head that was opposed during recording. What is claimed is: 1. A magnetic disk device of a double-sided magnetic recording system, which prohibits the output of the access signal when the access signal is accessed;
