Abstract

In accordance with embodiments of the present disclosure, a sequential storage media system for writing to both sides of a sequential storage medium, may include a first head and a second head. The first head may be configured to maintain contact with a first side of the sequential storage medium and read data from and/or write data to the first side as the sequential storage medium is wound between reels for winding the sequential storage medium. The second head may be configured to maintain contact with a second side of the sequential storage medium and read data from and/or write data to the second side as the sequential storage medium is wound between reels for winding the sequential storage medium.

Claims (42)

1 . (canceled)

2 . A sequential storage media system for writing to both sides of a sequential storage medium, comprising:

a first head configured to maintain contact with a first side of the sequential storage medium and read data from and/or write data to the first side as the sequential storage medium is wound between reels for winding the sequential storage medium; and

a second head configured to maintain contact with a second side of the sequential storage medium and read data from and/or write data to the second side as the sequential storage medium is wound between reels for winding the sequential storage medium; wherein the first head and the second head are each movable relative to the sequential storage medium in a direction substantially perpendicular to a portion of the sequential storage medium adjacent to the first head and the second head between a first position and a second position and vice versa, wherein:

in the first position, the first head maintains contact with the sequential storage medium; and

in the second position, the second head maintains contact with the sequential storage medium.

3 . The sequential storage media system of claim 2 , further comprising a first pair of guides and a second pair of guides, wherein:

in the first position, the first pair of guides creates mechanical tension causing the first side to maintain contact with the first head; and

in the second position, the second pair of guides creates mechanical tension causing the second side to maintain contact with the second head.

4 . The sequential storage media system of claim 3 , wherein the first pair of guides and second pair of guides are fixed, and the first head and the second head are movable relative to the first pair of guides and the second pair of guides.

5 . A sequential storage media system for writing to both sides of a sequential storage medium, comprising:

a first head configured to maintain contact with a first side of the sequential storage medium and read data from and/or write data to the first side as the sequential storage medium is wound between reels for winding the sequential storage medium;

a second head configured to maintain contact with a second side of the sequential storage medium and read data from and/or write data to the second side as the sequential storage medium is wound between reels for winding the sequential storage medium; and

a first pair of guides and a second pair of guides, wherein:

each of the second pair of guides is movable, other than by rotational movement of the second pair of guides, relative to the sequential storage medium and the first pair of guides between a first position and a second position and vice versa;

in the first position, the first pair of guides creates mechanical tension causing the first side to maintain contact with the first head; and

in the second position, the second pair of guides creates mechanical tension causing the second side to maintain contact with the second head.

6 . (canceled)

7 . A method for writing to both sides of a sequential storage medium, comprising:

maintaining contact between a first head and a first side of the sequential storage medium and writing data to the first side as the sequential storage medium is wound between reels for winding the sequential storage medium;

maintaining contact between a second head and a second side of the sequential storage medium and writing data to the second side as the sequential storage medium is wound between reels for winding the sequential storage medium; and

moving the first head and the second head relative to the sequential storage medium in a direction substantially perpendicular to a portion of the sequential storage medium adjacent to the first head and the second head between a first position and a second position and vice versa, wherein:

in the first position, the first head maintains contact with the sequential storage medium; and

in the second position, the second head maintains contact with the sequential storage medium.

8 . The method of claim 7 , further comprising:

in the first position, creating mechanical tension with a first pair of guides causing the first side to maintain contact with the first head; and

in the second position, creating mechanical tension with a second pair of guides causing the second side to maintain contact with the second head.

9 . The method of claim 8 , wherein the first pair of guides and second pair of guides are fixed, and the first head and the second head are movable relative to the first pair of guides and the second pair of guides.

10 .- 11 . (canceled)

12 . An information handling system comprising:

a processor; and

a sequential storage media system for writing to both sides of a sequential storage medium, comprising:

a first head configured to maintain contact with a first side of the sequential storage medium and read data from and/or write data to the first side as the sequential storage medium is wound between reels for winding the sequential storage medium; and

a second head configured to maintain contact with a second side of the sequential storage medium and read data from and/or write data to the second side as the sequential storage medium is wound between reels for winding the sequential storage medium;

wherein the first head and the second head are each movable relative to the sequential storage medium in a direction substantially perpendicular to a portion of the sequential storage medium adjacent to the first head and the second head between a first position and a second position and vice versa, wherein:

in the first position, the first head maintains contact with the sequential storage medium; and

in the second position, the second head maintains contact with the sequential storage medium.

13 . The information handling system of claim 12 , further comprising a first pair of guides and a second pair of guides, wherein:

in the first position, the first pair of guides creates mechanical tension causing the first side to maintain contact with the first head; and

in the second position, the second pair of guides creates mechanical tension causing the second side to maintain contact with the second head.

14 . The information handling system of claim 13 , wherein the first pair of guides and second pair of guides are fixed, and the first head and the second head are movable relative to the first pair of guides and the second pair of guides.

15 . (canceled)
