機構。[Claims for Utility Model Registration] (1) A floppy disk equipped with a center hole for fitting into a spindle shaft of a spindle mechanism constituting a recording medium rotation mechanism and a drive hole for positioning with respect to a drive pin of the spindle mechanism. In the recording medium of the apparatus, in the inner side surface portion of the drive hole that the drive pin contacts while rotating, the side surface portion corresponding to the rotational direction of the drive pin is formed based on the side surface shape of the drive pin. A recording medium for a floppy disk device, characterized in that it is formed with a predetermined curved shape. (2) In a recording medium rotation mechanism of a floppy disk device that rotationally drives a recording medium provided with a center hole and a drive hole in the center, a spindle shaft that fits into the center hole and transmits rotational driving force; and a drive pin that rotates with the rotation of the spindle shaft and contacts a side surface portion formed in a predetermined curved shape corresponding to the rotational direction on the positioning side surface portion inside the drive hole to rotationally drive the recording medium. A recording medium rotation mechanism for a floppy disk device characterized by:
