Abstract
A cartridge for a disk drive has a rigid shell with two keying grooves along the top and bottom edges of one side of the cartridge. These mate with projections on the cartridge receiving slot in the drive. One of the grooves extends deeper into one planar surface of the cartridge than the other groove. This prevents insertion of the cartridge with any other orientation of the cartridge than the correct orientation.
Claims5
A cartridge for a drive having read/write heads which record data on a recording medium in said cartridge comprising:
- a shell having a front, a back and two sides between substantially flat, planar surfaces;
- the recording medium being in said shell;
- an opening in the front of said shell for access by said read/write heads to said recording medium;
- and
- two keying grooves along top and bottom edges of one side of said shell, a first of said keying groves being along said top edge of one side of said shell, a second of said keying grooves being coextensive with said first groove along said bottom edge of one side of said shell, one of said keying grooves extending deeper into one of said planar surfaces than the other groove extends into the other planar surface, said keying grooves mating with corresponding structure in said drive to prevent said cartridge from being inserted into said drive with the wrong orientation.
The combination of a cartridge containing a recording medium and a drive having read/write heads which read/record data on said recording medium, said cartridge comprising:
- a shell having a front, back, and two sides between top and bottom substantially flat planar surfaces;
- the recording medium being in said shell;
- an opening in the front of said shell for access by said read/write heads to said recording medium;
- and
- two keying grooves along top and bottom edges of one side of said shell, a first of said keying groves being along said top edge of one side of said shell, a second of said keying grooves being coextensive with said first groove along said bottom edge of one side of said shell, one of said keying grooves extending deeper into one of said planar surfaces than the other groove extends into the other planar surface, to prevent said cartridge from being inserted into said drive with the wrong orientation;
- a drive having a slot into which said cartridge is inserted for engagement of said read/write heads with said recording medium;
- and
- two projections at one side of said slot, said projections mating with said keying grooves to ensure proper insertion of said cartridge into said drive.
