Abstract
Vending apparatus for optical disk restoration has a housing for receiving the disk form a customer; a disk inspection device to determine whether the disk is correctly positioned for polishing and providing a signal indicative of disk position, a disk perforation detecting device providing a signal indicative of any perforation in a reflective layer of the disk; and a device for ejecting a perforated disk from the housing. A user interface requests and receives payment from a customer in response to a signal by the detecting device that the reflective layer is imperforate and provides a signal indicating receipt of correct payment. Polishing wheels polish, with slurry, an exposed light receiving surface of a data carrying protective layer of the disk to ameliorate scratches in response to a signal from the user interface of correct payment and a device ejects a polished disk from the housing to a customer.
