ABSTRACT:
An assembly for transferring discs between disc manufacturing machinery or processes comprises a series of storage cassettes having discs stored therein. Each stored disc is retrieved from the cassette and placed into a shuttle which carries the disc while it is processed. The processed disc is retrieved from the shuttle subsequent to the disc manufacturing process and placed into a second storage cassette. The apparatus transfers the discs by gripping them between a stationary member which engages the edge of the disc and a selectably moveable member which engages the disc hole such that the disc is pinched between the two gripping members. The gripping and transferring functions are controlled by a computer.
