ABSTRACT:
Processing cassette for processing of hard rigid memory disks including a plurality of open supported opposing disk dividers for supporting a plurality of disks in alignment by the dividers of the cassette. The cassette is intended for use in automated robotic processing of the disks while in the cassette. The wafer cassette includes similar mirror image like opposed ends with deep wide downwardly inverted arches. The dividers are supported by two pairs of horizontal supports secured to the ends, providing for both upper and lower open process wash areas between each of the dividers for passage of liquids during automated robotic processing. Surfaces of the cassette are non-porous and extremely smooth. All edges and corners are radiused facilitating quick and effective drying of the cassette during robotic processing. On-center processing is provided for the disk processing cassette, where the carrier center of gravity is on-center for an axis of centrifugal disk processing machinery. Each of the dividers, in upper and lower cross sections, are geometrically configured for maximum passage and ease of entry of fluids during processing.
