Abstract

A tape media cartridge includes a cartridge housing having a standard form factor, a cartridge reel that is coupled to and retained within the cartridge and a tape media. The tape media can be selectively wound onto the cartridge reel between a fully wound state, a partially wound state and an unwound state. The tape media forms a media hollow cylinder having a media outer diameter and a media inner diameter that varies depending upon the state of the tape media. When the tape media is in the fully wound state, the tape media has a ratio of the media outer diameter to media inner diameter of at least approximately 95:43. The cartridge housing can include a side wall having a wall center and wall edge, the side wall having a side wall thickness that gradually increases from the side wall center to the side wall edge.

First claim

What is claimed is:

1. A tape media cartridge, comprising:
a cartridge housing having a standard Ultrium form factor, the cartridge housing including a side wall having a wall center and a wall edge, the side wall having a side wall thickness that gradually increases from the side wall center to the side wall edge;
a cartridge reel that is coupled to and retained within the cartridge housing;
a tape media that is selectively wound onto the cartridge reel between a fully wound state, a partially wound state and an unwound state, the tape media forming a media hollow cylinder having a media outer diameter and a media inner diameter that varies depending upon the state of the tape media; and
a label recess that is connected to the side wall, the label recess being tapered to accommodate the tape media;
wherein when the tape media is in the fully wound state, a ratio of the media outer diameter to the media inner diameter is at least approximately 95:43.

2. The tape media cartridge of claim 1 wherein the side wall is tapered to accommodate the tape media.

3. The tape media cartridge of claim 1 wherein when the tape media is in the fully wound state, the tape media has a media width so that a ratio of the media inner diameter to the media width is less than approximately 43:13.

4. The tape media cartridge of claim 3 wherein when the tape media is in the fully wound state, a ratio of the media outer diameter to the media width is at least approximately 95:13.

5. The tape media cartridge of claim 1 wherein the cartridge reel includes a reel flange having an outer edge radius of curvature of less than 0.4 mm.

6. The tape media cartridge of claim 1 wherein the cartridge reel includes a reel flange having a flange thickness of less than 2.90 mm.

7. The tape media cartridge of claim 1 wherein the cartridge reel is at least partially formed from a glass filling.

8. The tape media cartridge of claim 1 wherein when the tape media is in the fully wound state, the media inner diameter is less than 43 mm.

9. The tape media cartridge of claim 1 wherein when the tape media is in the fully wound state, the media outer diameter is greater than 95 mm.

10. The tape media cartridge of claim 1 wherein when the tape media is in the fully wound state, the media width is greater than 13 mm.

11. The tape media cartridge of claim 1 wherein in the fully wound state, the media hollow cylinder has a volume of greater than 20.8 cm 3 .

12. The tape media cartridge of claim 1 wherein the cartridge housing is at least partially formed with a glass filling.

13. A tape media cartridge, comprising:
a cartridge housing having a standard Ultrium form factor, the cartridge housing including a side wall having a wall center and a wall edge, the side wall having a side wall thickness that gradually increases from the side wall center to the side wall edge, the cartridge housing including a label recess that is connected to the side wall;
a tape media that is selectively wound onto the cartridge reel between a fully wound state, a partially wound state and an unwound state, the tape media having a media width, the tape media forming a media hollow cylinder having a media inner diameter and a media outer diameter that varies depending upon the state of the tape media, wherein the label recess is tapered to accommodate the tape media; and
a cartridge reel that is coupled to and retained within the cartridge housing, the cartridge reel including a reel flange having an outer edge radius of curvature of less than 0.3 mm, the reel flange having a flange thickness of less than 2.85 mm;
wherein when the tape media is in the fully wound state, a ratio of the media outer diameter to the media inner diameter is at least approximately 95:43, and a ratio of the media inner diameter to the media width is less than approximately 40:13.

14. The tape media cartridge of claim 1 wherein the cartridge housing is at least partially formed from one of a plastic, a metal, and an adhesive.

15. The tape media cartridge of claim 1 wherein the cartridge reel is at least partially formed from one of a plastic, a metal, and an adhesive.

16. The tape media cartridge of claim 13 wherein the cartridge reel is at least partially formed from a glass filling.

17. The tape media cartridge of claim 13 wherein the cartridge housing is at least partially formed from a glass filling.

18. The tape media cartridge of claim 13 wherein the cartridge housing is at least partially formed from one of a plastic, a metal, and an adhesive.

19. The tape media cartridge of claim 13 wherein in the fully wound state, the media hollow cylinder has a volume of greater than 20.8 cm 3 .

20. The tape media cartridge of claim 13 wherein the reel flange is at least partially formed from a glass filling.
