ABSTRACT:
When a large diameter disc is inserted into the disc drive, diameter sensing probes detect the large diameter and unlock movable disc guides and subsequently induce the guides to separate to levels wherein passage of the large diameter disc is facilitated. The guides are locked in a manner which prevents the same from returning to the positions suited for guiding small diameter discs until such time as the large diameter disc is unloaded from the device.
Levers mounted in the drive respond to the diameter of the disc loaded and assume configurations relative to the diameter of the loaded disc. The levers are locked in a configuration suited for small discs until such time as a large disc is introduced. At this time the levers are unlocked. A locking mechanism senses the peripheral edge of the disc and hold the arrangement in a configuration suited for the larger diameter.
