Abstract

Claims (36)

1. A tape cartridge for retaining a magnetic tape, the tape cartridge being configured to be selectively positioned substantially within a tape drive, the tape cartridge comprising:

a cartridge body including a cartridge length from a front to a rear of the cartridge body, and a cartridge width from a first side to a second side of the cartridge body; and

a cartridge hub that is positioned within the cartridge body, the cartridge hub being configured so that the magnetic tape is wound around the cartridge hub within the cartridge body, the cartridge hub including a hub diameter;

wherein the cartridge length and the cartridge width provide boundaries for a maximum wound tape diameter as the magnetic tape is wound around the cartridge hub within the cartridge body; and

wherein a ratio of the maximum wound tape diameter to the hub diameter is at least approximately 3.50:1.

2. The tape cartridge of claim 1 wherein the ratio of the maximum wound tape diameter to the hub diameter is at least approximately 4.50:1.

3. The tape cartridge of claim 1 wherein the cartridge hub is fixed in position relative to the cartridge body.

4. The tape cartridge of claim 3 further comprising a drive engaging member that is coupled to the cartridge hub; and wherein the tape drive includes a cartridge engaging member that selectively engages the drive engaging member, a cartridge reel motor that rotates the cartridge engaging member, the drive engaging member and the cartridge hub as the magnetic tape is wound around the cartridge hub, and a resilient member that moves the cartridge engaging member so that the cartridge engaging member engages the drive engaging member.

5. The tape cartridge of claim 4 wherein the drive engaging member has a diameter that is greater than the hub diameter.

6. The tape cartridge of claim 1 further comprising a drive engaging member that is coupled to the cartridge hub; wherein the tape drive includes a cartridge engaging member that selectively engages the drive engaging member, and a cartridge reel motor that rotates the cartridge engaging member, the drive engaging member and the cartridge hub as the magnetic tape is wound around the cartridge hub; and wherein the drive engaging member has a diameter that is greater than the hub diameter.

7. The tape cartridge of claim 1 further comprising an alignment assembly that is coupled to the cartridge body, the alignment assembly including an alignment roller that is in contact with an outer surface of the magnetic tape as the magnetic tape is wound around the cartridge hub.

8. The tape cartridge of claim 7 wherein the alignment assembly further includes a resilient member that is coupled to the alignment roller, the resilient member providing a biasing force such that the alignment roller is always in contact with the outer surface of the magnetic tape as the magnetic tape is wound around the cartridge hub.

9. The tape cartridge of claim 1 wherein the cartridge body further includes a cartridge height from a top to a bottom of the cartridge body; wherein the magnetic tape has a tape width; and wherein a tape width ratio of the tape width to the cartridge height is at least approximately 0.65:1.

10. The tape cartridge of claim 9 further comprising an alignment assembly that is coupled to the cartridge body, the alignment assembly including an alignment roller that is in contact with an outer surface of the magnetic tape as the magnetic tape is wound around the cartridge hub.

11. The tape cartridge of claim 1 wherein the cartridge body has a body thickness of less than approximately 1.25 millimeters.

12. The tape cartridge of claim 1 wherein the tape cartridge is an LTO compatible tape cartridge.

13. A tape cartridge for retaining a magnetic tape, the tape cartridge being configured to be selectively positioned substantially within a tape drive, the tape cartridge comprising:

a cartridge body including a cartridge height from a top to a bottom of the cartridge body; and

a cartridge hub that is positioned within the cartridge body, the cartridge hub being configured so that the magnetic tape is wound around the cartridge hub within the cartridge body;

wherein the magnetic tape has a tape width; and

wherein a tape width ratio of the tape width to the cartridge height is at least approximately 0.65:1.

14. The tape cartridge of claim 13 wherein the tape width ratio of the tape width to the cartridge height is at least approximately 0.75:1.

15. The tape cartridge of claim 13 wherein the cartridge hub is fixed in position relative to the cartridge body.

16. The tape cartridge of claim 15 further comprising a drive engaging member that is coupled to the cartridge hub; and wherein the tape drive includes a cartridge engaging member that selectively engages the drive engaging member, a cartridge reel motor that rotates the cartridge engaging member, the drive engaging member and the cartridge hub as the magnetic tape is wound around the cartridge hub, and a resilient member that moves the cartridge engaging member so that the cartridge engaging member engages the drive engaging member.

17. The tape cartridge of claim 13 further comprising an alignment assembly that is coupled to the cartridge body, the alignment assembly including an alignment roller that is in contact with an outer surface of the magnetic tape as the magnetic tape is wound around the cartridge hub.

18. The tape cartridge of claim 17 wherein the alignment assembly further includes a resilient member that is coupled to the alignment roller, the resilient member providing a biasing force such that the alignment roller is always in contact with the outer surface of the magnetic tape as the magnetic tape is wound around the cartridge hub.

19. A tape cartridge for retaining a magnetic tape, the tape cartridge being configured to be selectively positioned substantially within a tape drive, the tape cartridge comprising:

a cartridge body including a cartridge length from a front to a rear of the cartridge body, a cartridge width from a first side to a second side of the cartridge body, and a cartridge height from a top to a bottom of the cartridge body;

a cartridge hub that is positioned within the cartridge body, the cartridge hub being configured so that the magnetic tape is wound around the cartridge hub within the cartridge body, the cartridge hub including a hub diameter; and

an alignment assembly that is coupled to the cartridge body, the alignment assembly including an alignment roller and a resilient member that is coupled to the alignment roller, the resilient member providing a biasing force such that the alignment roller is always in contact with an outer surface of the magnetic tape as the magnetic tape is wound around the cartridge hub;

wherein the cartridge length and the cartridge width provide boundaries for a maximum wound tape diameter as the magnetic tape is wound around the cartridge hub within the cartridge body;

wherein a ratio of the maximum wound tape diameter to the hub diameter is at least approximately 4.50:1;

wherein the magnetic tape has a tape width; and

wherein a tape width ratio of the tape width to the cartridge height is at least approximately 0.75:1.

20. The tape cartridge of claim 19 wherein the cartridge hub is fixed in position relative to the cartridge body.

21. The tape cartridge of claim 20 further comprising a drive engaging member that is coupled to the cartridge hub; and wherein the tape drive includes a cartridge engaging member that selectively engages the drive engaging member, a cartridge reel motor that rotates the cartridge engaging member, the drive engaging member and the cartridge hub as the magnetic tape is wound around the cartridge hub, and a resilient member that moves the cartridge engaging member so that the cartridge engaging member engages the drive engaging member.
