囲第１項記載の磁気記録再生装置。[Claims for Utility Model Registration] (1) The movement of the head is linked to the rotation of the spindle, and the lock pin, which rotates with the rotation of the spindle, engages with the engaging portion formed on the hub of the floppy disk, thereby locking the media. In a magnetic recording and reproducing device that records and reproduces information on the medium in a spiral manner by rotating the spindle, a reversibly rotatable motor is used as the motor for rotating the spindle, and the spindle is loosely inserted into the engaging portion. 1. A magnetic recording and reproducing device characterized in that the track is formed in an arc shape along approximately the semicircle of a circle concentric with the center hole, and the track to be traced is changed between the forward and backward paths of the head. (2) The magnetic recording and reproducing device according to claim 1, wherein the engaging portion is an engaging groove formed of an arcuate groove.
