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.
Referring to the drawings, Fig. 1 is a side view which shows a disk drive unit
with a removable disk storage cartridge. 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,
cause the disk platters to be uniformly expanded out with the proper spacing
maintained between them. At this point, the jaws (3/disk platter) are activated,
and emerge out of the spindle shaft. 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...
