Abstract
Abstract 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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
15 words
A tape cartridge operatively engagable in a disc drive unit for the data transfer therebetween.
Claim 2
Dependent Claim
15 words
A tape cartridge operatively engagable in a disc drive unit for the data transfer therebetween.
Claim 3
Dependent Claim
80 words
A tape cartridge according to Claim 1, comprising: a tape (20) suitable for transferring data between the tape (20) and a read/write head of said disc-drive unit; registration means (22,23,26,43,210,211) for registering a portion of the tape (20) at a predetermined location (L) at which data can be transferred between the tape (20) and the disc-drive head; tape-feed means (213,53 to 55) for feeding the tape (20) past said predetermined location (L);and storage means (51,52) for storing the tape (20).
Claim 4
Dependent Claim
69 words
A tape cartridge according to claim 2, wherein said registration means comprises: cartridge-alignment means (43,210,211) for aligning the tape cartridge with the disc-drive unit when the tape cartridge is loaded into the disc-drive unit; and guide means (22,23,26) for guiding the tape (20) within the tape cartridge such that, when the tape cartridge is aligned with the disc drive, the tape (20) is registered at said predetermined location (L).
Claim 5
Dependent Claim
67 words
A tape cartridge according to claim 3, further comprising: a protective shell (29) enclosing the tape (20), said shell having a bottom portion that includes therein at least two holes (43,211) located such that, when the tape cartridge is loaded into the disc drive, each of the holes (43,211) fits over a corresponding projection in the disc drive unit and aligns the tape cartridge with the unit.
Claim 6
Dependent Claim
65 words
5, A tape cartridge according to claim 5 for use with a disc drive unit having a motor shaft, wherein one (43) of said holes in the bottom portion of the shell (29) is arranged to fit over the motor shaft, whereby the motor shaft functions as one of the said predetermined drive projections utilized to align the tape cartridge with said predetermined location (L).
Claim 7
Dependent Claim
37 words
A tape cartridge according to claim 3, wherein the tape cartridge includes a section (A) that is insertable into the disc drive unit, the tape (20) within said section (A) being contained within a substantially planar region.
