気記録再生装置のフロツピデイスク。[Claims for Utility Model Registration] A spindle is loosely inserted into a center hole drilled in the approximate center of the hub, and a lock pin, which rotates as the spindle rotates, is urged by an elastic body and drilled into the hub. In a floppy disk of a magnetic recording/reproducing device, which engages with a lock hole formed in the disk to rotate the medium, and records and reproduces information through the rotation of the medium, along a part of a circle concentric with the center hole, A continuous lock pin guide inclined portion is provided from an appropriate position at the rear end of the lock hole in the direction of rotation of the medium during recording/reproduction to the lower surface of the hub in the direction opposite to the direction of rotation of the medium. A floppy disk is a magnetic recording and reproducing device.
