Abstract

A spring-like clip for a spool of tape, one end of the clip being attached to one end of the tape, and another end of the clip having an engagement feature that allows the clip to be pulled from the spool. The clip is configured to curve around the spool to hold the tape in place. In one general embodiment, a product includes a reel, a tape coupled to the reel, and a spring-like clip coupled to a free end of the tape. The clip is selectively positionable in a wrapped position where the clip wraps around a portion of the tape when the tape is wound onto the reel, thereby holding the portion of the tape in place on the reel. Systems for using various types of such products are presented, and generally include a tape drive configured for reading data from tape stored on such products.

First claim

What is claimed is:

1. A product, comprising:
a reel;
a tape coupled to the reel; and
a spring-like clip coupled to a free end of the tape, the clip being selectively positionable in a wrapped position where the clip wraps around a portion of the tape when the tape is wound onto the reel, thereby holding the portion of the tape in place on the reel,
wherein the spring-like clip is resiliently deformable,
wherein the spring-like clip has a rounded profile along a longitudinal length thereof when decoupled from the tape and in the absence of any external forces.

2. The product as recited in claim 1 , wherein the clip includes an engagement feature configured to enable the clip to be pulled from the wrapped position.

3. The product as recited in claim 2 , wherein the engagement feature is a bent portion of the spring-like clip.

4. The product as recited in claim 2 , wherein the engagement feature includes at least one of a hole and a barb.

5. The product as recited in claim 1 , wherein a free end of the clip has a bent portion.

6. The product as recited in claim 1 , wherein at least one surface of the clip has a surface feature for reducing surface friction of the clip.

7. The product as recited in claim 1 , wherein the stiffness of the clip varies along its length.

8. The product as recited in claim 7 , wherein a free end of the clip has greater stiffness than an end of the clip coupled to the tape.

9. The product as recited in claim 1 , wherein the length of the clip between a free end thereof and an end thereof coupled to the tape is at least one-half of the circumference of an outer surface of the tape when the tape is wound completely on the reel.

10. The product as recited in claim 1 , wherein the length of the clip between a free end thereof and an end thereof coupled to the tape is greater than the circumference of an outer surface of the tape when the tape is wound completely on the reel.

11. The product as recited in claim 1 , wherein the clip has a width in the range from 20% of the tape's width to 100% of the tape's width.

12. The product as recited in claim 1 , wherein the clip's width is greater than the tape's width.

13. The product as recited in claim 1 , wherein the clip is coupled to the free end of the tape by a tape leader having a length as measured between the clip and the tape of at least one circumference of an outer surface of the tape when the tape is wound completely on the reel.

14. The product as recited in claim 1 , wherein the spring-like clip is magnetically permeable.

15. The product as recited in claim 1 , wherein the clip's width is greater than the tape's width, wherein flanges of the reel include grooves for receiving the clip, wherein the clip is radially offset from an outermost wrap of the tape.

16. The product as recited in claim 1 , wherein stiffness of the clip varies along its length, wherein a free end of the clip has greater stiffness than an end of the clip coupled to the tape.

17. The product as recited in claim 1 , wherein the length of the clip between a free end thereof and an end thereof coupled to the tape is between 50% and 100% of the circumference of an outer surface of the tape when the tape is wound completely on the reel.

18. The product as recited in claim 1 , wherein the length of the clip between a free end thereof and an end thereof coupled to the tape is greater than the circumference of an outer surface of the tape when the tape is wound completely on the reel.

19. The product as recited in claim 1 , wherein a free end of the clip has a bent portion for enabling optical detection of the bent portion by an optical detector.

20. A spring-like clip for a spool of tape, one end of the clip being attached to one end of the tape, and another end of the clip having an engagement feature that allows the clip to be pulled from the spool, wherein the clip is configured to curve around the spool to hold the tape in place wherein the spring-like clip is resiliently deformable, wherein the spring-like clip has a rounded profile along a longitudinal length thereof when decoupled from the spool and in the absence of any external forces, wherein the length of the clip between a free end thereof and an end thereof coupled to the tape is between 50% and 100% of the circumference of an outer surface of the tape when the tape is wound completely on the reel, wherein a free end of the clip has a bent portion for enabling optical detection of the bent portion by an optical detector.

21. The clip of claim 20 , wherein the clip is configured to assume a relatively less-curved geometry when pulled by the engagement feature, thereby permitting the clip to be passed to a take-up reel.

22. The clip of claim 20 , wherein the engagement feature is configured (i) to engage a transfer mechanism when loading the tape and (ii) disengage the transfer mechanism when unloading the tape.

23. The clip of claim 20 , the clip including surface features that reduce surface friction between the clip and a surface abutting the clip, and facilitate clip unloading.

24. The clip of claim 20 , wherein the clip has varied stiffness along its length for facilitating uncurling of the clip when loading the tape onto a take-up mechanism, while maintaining the holding properties of the clip.
