ABSTRACT:
Multi-disk processing system and method of continuous finishing of memory media disks for digital data storage systems in preparation for magnetic memory coating, comprising four main sub-systems: 1) multiple driven spindles mounted on a chassis, at 3, 6, 9 and 12 o'clock positions; 2) finishing tape head units mounted on a base; 3) a robotic handler for loading and unloading disks onto/off at least one of the spindles; and 4) a programmable system controller that controls the sub-system operations and loading/unloading. The tape head sub-system includes its own programmable controller and sensors for control of the finishing tape advance. The multiple spindles and handler rotate relative to each other. In a preferred embodiment, the spindles are mounted on a rotating turntable that also oscillates. Alternately, the spindles are fixed in position and a rotating handler with multiple grippers for simultaneously loading/unloading disks from all spindles at once is used.
