ク装置。 The device is equipped with means for cumulatively recording the number of times a spindle motor is driven in a specific recording location on the disk as the number of CSSs of a hard disk that uses a contact start/stop (CSS) method, and the control circuit drives the spindle motor. After the rotation reaches a steady state, read out the CSS number recorded from the recording location of the magnetic head, increment the CSS number by 1, and write the updated cumulative CSS number in the recording location. A magnetic disk device characterized in that it is in a standby state.
