Compressed/Expandable Removable Disk Stack Storage Concept

This article describes a disk storage cartridge, containing several disk platters sandwiched together, which is removable from a disk drive unit.

Fig. 2 is a detail view of a portion of the drive unit spindle shaft, and Fig. 3 is a top view of the shaft. The removable cartridge consists of several disk platters sandwiched together like a compressed accordion. The disk platters can be made for magnetic and/or optical disk storage media. Each disk platter is separated by a thin-film platform. These platforms/separators are successively interconnected to the top cover of the removable cartridge. Inserting the cartridge into the drive automatically releases the top cover of the cartridge. The top cover of the cartridge is drawn up to the top of the disk drive, and locked in place. The bristles on each side, on the inside of the drive unit,

They clamp up and down onto each disk platter. Once this has occurred, the read/write head(s) can be brought into place over the disk platter(s).

Fig. 4 is a top view of the disk drive unit mechanism which is used to lift the top cover of the cartri...
