Tape cartridge.

A tape cartridge is provided which is arranged to utilize the read/write head(s) in a disc drive to read data from and/or write data to the tape (20). The tape cartridge has a section (A) of a size and shape which enables it to be inserted into the disc drive to locate a portion of the tape (20) at a location suitable for exchanging data with the disc drive head(s). The tape cartridge comprises the tape media (20) itself, means (22,23,26,210,211) for registering the tape media with respect to the read/write head(s) of a disc drive, means for feeding the tape media past the read/write head(s) in the disc drive, and means for storing that portion of the tape media which is not currently being fed past the read/write head(s). The tape cartridge may include a transmission (213) that enables it to utilize the disc-drive spindle motor for feeding the tape. In one embodiment, the transmission includes a clutch for enabling the tape feed direction to be reversed.
