Abstract
A magnetic disk device of the present invention is configured so that a stopper for controlling the movement of a carriage arm is adapted to give rise to play in controlling the carriage arm when the stopper is in the closed state. When a disk rotating means is actuated, the magnetic disk device permits a disk and a magnetic head in the state of fast mutual adhesion to be separated from each other by causing the carriage arm to swing with the stopper kept in the closed state, and consequently, the magnetic disk device enables the disk to rotate without fail.
