Abstract

Various embodiments relate to apparatuses and methods for loading and unloading a tape storage medium. In one embodiment, an apparatus for such purpose includes a mechanized take-up reel. The mechanized take-up reel includes an inner hub, an outer hub being selectively nonrotatably coupleable with the inner hub (where at least one of the hubs is coupled to a rotating mechanism), a tongue coupled to the inner hub, and a slot in the outer hub for permitting the tongue to extend beyond a periphery of a tape engaging surface of the outer hub upon relative rotation between the inner and outer hubs.

First claim

What is claimed is:

1. An apparatus for loading and unloading a tape storage medium, the apparatus comprising:
a mechanized take-up reel having:
an inner hub;
an outer hub being selectively nonrotatably coupleable with the inner hub, wherein at least one of the hubs is coupled to a rotating mechanism;
a tongue coupled to the inner hub;
a slot in the outer hub for permitting the tongue to extend beyond a periphery of a tape engaging surface of the outer hub upon relative rotation between the inner and outer hubs; and
a flange coupled with the outer hub,

wherein the flange comprises a bearing for enabling rotation of the inner hub with respect to the outer hub.

2. The apparatus of claim 1 , comprising a mechanism configured to engage the mechanized take-up reel for enabling and/or disabling the nonrotatable coupling.

3. The apparatus of claim 2 , wherein the mechanism acts as a positioning device for preventing rotation of the outer hub when the inner hub rotates.

4. The apparatus of claim 2 , comprising a pawl, wherein the mechanism is configured to engage the pawl for enabling and/or disabling the nonrotatable coupling.

5. The apparatus of claim 1 , wherein the tongue comprises a distal end configured to detachably couple with a feature coupled to a tape storage medium.

6. The apparatus of claim 5 , wherein the inner and outer hubs are configured to be nonrotatably coupled when in a predefined alignment relative to each other, wherein the apparatus is physically configured such that a distal edge of the feature resides in the slot of the outer hub when the inner and outer hubs are nonrotatably coupled.

7. An apparatus for loading and unloading a tape storage medium, the apparatus comprising:
a mechanized take-up reel having:
an inner hub;
an outer hub being selectively nonrotatably coupleable with the inner hub, wherein at least one of the hubs is coupled to a rotating mechanism;
a tongue coupled to the inner hub;
a slot in the outer hub for permitting the tongue to extend beyond a periphery of a tape engaging surface of the outer hub upon relative rotation between the inner and outer hubs;
a flange coupled with the outer hub; and
a pawl,
wherein the flange comprises a pivot that enables movement of the pawl to selectively nonrotatably couple the inner hub with the outer hub.

8. The apparatus of claim 7 , wherein the tongue wraps around the inner hub and is completely retracted from the slot when in a retracted position.

9. The apparatus of claim 7 , wherein the tongue comprises a distal end configured to detachably couple with a feature coupled to a tape storage medium.

10. The apparatus of claim 9 , wherein the inner and outer hubs are configured to be nonrotatably coupled when in a predefined alignment relative to each other, wherein the apparatus is physically configured such that a distal edge of the feature resides in the slot of the outer hub when the inner and outer hubs are nonrotatably coupled.

11. The apparatus of claim 7 , wherein the tongue is fabricated from a resiliently deformable material.

12. The apparatus of claim 7 , wherein a distal end of the tongue has a generally flattened shape.

13. The apparatus of claim 7 , wherein the outer hub is a hub/flange component.

14. The apparatus of claim 7 , wherein the inner hub is coupled to the rotating mechanism.

15. The apparatus of claim 7 , wherein the outer hub is coupled to the rotating mechanism.

16. The apparatus of claim 7 , wherein the flange comprises a bearing for enabling rotation of the inner hub with respect to the outer hub.

17. The apparatus of claim 7 , comprising a mechanism configured to engage the mechanized take-up reel for enabling and/or disabling the nonrotatable coupling.

18. The apparatus of claim 17 , wherein the mechanism acts as a positioning device for preventing rotation of the outer hub when the inner hub rotates.

19. The apparatus of claim 17 , comprising a pawl, wherein the mechanism is configured to engage the pawl for enabling and/or disabling the nonrotatable coupling.

20. An apparatus for loading and unloading a tape storage medium, the apparatus comprising:
a mechanized take-up reel having:
an inner hub;
an outer hub being selectively nonrotatably coupleable with the inner hub, wherein at least one of the hubs is coupled to a rotating mechanism;
a tongue coupled to the inner hub;
a slot in the outer hub for permitting the tongue to extend beyond a periphery of a tape engaging surface of the outer hub upon relative rotation between the inner and outer hubs;
a flange coupled with the outer hub; and

a mechanism configured to engage the mechanized take-up reel for enabling and/or disabling the nonrotatable coupling.

21. The apparatus of claim 20 , wherein the mechanism acts as a positioning device for preventing rotation of the outer hub when the inner hub rotates.

22. The apparatus of claim 20 , comprising a pawl, wherein the mechanism is configured to engage the pawl for enabling and/or disabling the nonrotatable coupling.

23. The apparatus of claim 20 , wherein the flange comprises a bearing for enabling rotation of the inner hub with respect to the outer hub.

24. The apparatus of claim 20 , wherein the tongue comprises a distal end configured to detachably couple with a feature coupled to a tape storage medium.

25. The apparatus of claim 24 , wherein the inner and outer hubs are configured to be nonrotatably coupled when in a predefined alignment relative to each other, wherein the apparatus is physically configured such that a distal edge of the feature resides in the slot of the outer hub when the inner and outer hubs are nonrotatably coupled.
