Abstract:
A cartridge for a drive having an interlock and read/write heads which record data in said cartridge comprising:a shell having a front, back, and two sides between planar surfaces;a recording medium in said shell;an opening in said shell for access by said read/write heads to said recording medium; andonly one interlock mechanism on said front of said cartridge between said planar surfaces at one side of said shell, said interlock mechanism comprising a protrusion that prevents operation of a drive that does not have a cooperating interlock to accept said protrusion, said protrusion having a substantially round portion to cooperate with cooperating interlocks having a carved region such that said substantially round protrusion is accepted by said carved region of said cooperating interlocks, said cartridge further having two keying grooves along the top and bottom edges 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.
