Abstract
Apparatus for loading and precisely positioning a magnetic disc in a drive housing is provided including a spring biased stop member for receiving the interior edge of the magnetic disc and a pivotal cover flap for directing insertion of the disc interiorly of the drive housing. The cover flap is provided with a lock spring element which presses against the outer edge of the magnetic disc and pushes it against the biased stop. The stop member is formed with a locating projection and the cover flap is formed with beveled guide surfaces to precisely orient the disc within the drive housing. Displacement of the stop member is limited by cooperating abutment means, so that precise operating position of the disc in the drive housing is afforded. As the cover flap is closed, a cam member formed on the cover flap activates a clamping member simultaneous with the final positioning of the disc in the drive housing to effect a frictional connection between the magnetic disc and a rotatable drive device.
