Abstract

A tape embedded drive can include tape media for storing data, a first tape reel and a second tape reel, each coupled to one end of the tape media, and a head stack assembly (HSA). The HSA can include a first head assembly having at least one read head and one write head and a second head assembly having a non-operable head incapable of reading or writing. In an embodiment, the first head assembly is configured to be placed along a first side of the tape media and the second head assembly with the non-operable head is configured to be placed along a second side of the tape media opposite the first side of the tape media.

Claims (65)

1. A storage device comprising:

tape media for storing data;

a first tape reel coupled to one end of the tape media;

a second tape reel coupled to another end of the tape media; and

a head stack assembly (HSA) comprising:

a first head assembly comprising at least one read head and one write head, the first head assembly configured to be placed along a first side of the tape media;

a second head assembly comprising a non-operable head incapable of reading or writing, the second head assembly configured to be placed along a second side of the tape media opposite the first side of the tape media; and

a u-bracket support comprising:

a first side attached to a shaft, the first side coupled to a first head gimbal assembly (HGA) having the first head assembly;

a second side opposite the first side, the second side coupled to a second HGA having the second head assembly; and

a third side attached perpendicularly to the first side and the second side, wherein the first side, the second side and the third side form a channel around the tape media.

2. The storage device of claim 1 , wherein the second head assembly is configured to provide non-contact support to the tape media as it moves between the first head assembly and the second head assembly.

3. The storage device of claim 2 , wherein the non-contact support comprises an air or gas bearing between the second head assembly and the tape media.

4. The storage device of claim 1 , further comprising one of a 3.5 inch form factor casing and a 5.25 inch form factor casing.

5. The storage device of claim 1 , the storage device further comprising a casing containing the tape media, the first tape reel, the second tape reel, and the head stack assembly.

6. The storage device of claim 1 , wherein the HSA further comprises:

an elongated suspension coupled to the first head assembly at a first end of the elongated suspension, the elongated suspension coupled to the u-bracket support at a second end of the elongated suspension away from the first head assembly.

7. A storage device comprising:

tape media for storing data;

a first tape reel coupled to one end of the tape media;

a second tape reel coupled to another end of the tape media; and

a head stack assembly (HSA) comprising:

a first head assembly comprising at least one read head and one write head, the first head assembly configured to be placed along a first side of the tape media;

a second head assembly comprising a non-operable head incapable of reading or writing, the second head assembly configured to be placed along a second side of the tape media opposite the first side of the tape media; and

a support comprising:

a channel around the tape media;

a first portion coupled to a first head gimbal assembly (HGA) having the first head assembly; and

a second portion coupled to a second HGA having the second head assembly.

8. A storage device comprising:

tape media for storing data;

a first tape reel coupled to one end of the tape media;

a second tape reel coupled to another end of the tape media;

a head stack assembly (HSA) comprising:

a first head assembly comprising at least one read head and one write head, the first head assembly configured to be placed along a first side of the tape media; and

a second head assembly comprising a non-operable head incapable of reading or writing, the second head assembly configured to be placed along a second side of the tape media opposite the first side of the tape media; and

a second HSA comprising:

a third head assembly comprising at least one read head and one write head; and

a fourth head assembly comprising a non-operable head incapable of reading or writing;

wherein the HSA is configured to read the tape media moving in a forward direction and the second HSA is configured to read the tape media moving in a backward direction.

9. The storage device of claim 8 , wherein the second head assembly is parked while the tape media is moving in a forward direction.

10. The storage device of claim 9 , wherein the first head assembly is parked while the tape media is moving in a backward direction.

11. The storage device of claim 8 , further comprising a first parking ramp for the HSA and a second parking ramp for the second HSA.

12. The storage device of claim 8 , wherein the HSA is located in proximity to the first tape reel and the second HSA is located in proximity to the second tape reel.

13. A head stack assembly (HSA) for reading tape media, the HSA comprising:

a first head gimbal assembly (HGA) comprising at least one read head and one write head, the first HGA configured to be placed along a first side of the tape media;

a second HGA comprising a non-operable head incapable of reading or writing, the second HGA configured to be placed along a second side of the tape media opposite the first side of the tape media; and

a u-bracket comprising:

a first side attached to a shaft, the first side coupled to the first HGA;

a second side opposite the first side, the second side coupled to the second HGA; and

a third side attached perpendicularly to the first side and the second side, wherein the first side, the second side and the third side form a channel around the tape media.

14. The HSA of claim 13 , wherein the second HGA is configured to provide non-contact support to the tape media.

15. The HSA of claim 14 , wherein the non-contact support comprises an air or gas bearing between the second HGA and the tape media.

16. The HSA of claim 13 , the first HGA further comprising:

an elongated suspension coupled to the at least one read head and one write head; and

a support structure coupled to the elongated suspension away from the at least one read head and one write head.

17. A storage device comprising:

tape media for storing data;

means for winding the tape media along a reading head;

a first head stack assembly (HSA) comprising:

a first head assembly comprising the reading head, the first head assembly configured to be placed along a first side of the tape media; and

a second head assembly comprising a non-operable head incapable of reading, the second head assembly configured to be placed along a second side of the tape media opposite the first side of the tape media; and

a second HSA comprising:

a third head assembly comprising at least one read head and one write head; and

a fourth head assembly comprising a non-operable head incapable of reading or writing;

wherein the first HSA is configured to read the tape media moving in a forward direction and the second HSA is configured to read the tape media moving in a backward direction.
