Abstract
An optical data storage device includes an optical storage tape having one or more optical storage layers. A plurality of optical pickup units reads and/or writes data to the optical storage tape. A feed reel provides the optical storage tape to the optical pickup units. A guiding wheel that guides the optical storage tape when the optical storage tape is in the vicinity of the optical pickup units during read and/or write operations. Finally, a take-up reel receives the optical storage tape from the guiding wheel.
Claims20
An optical data storage device comprising:
- an optical storage tape having one or more optical storage layers;
- a plurality of optical pickup units for reading and writing data to the optical storage tape;
- a feed reel for providing the optical storage tape to the optical pickup units;
- a guiding wheel rotatably disposed on an axis of rotation, for guiding the optical storage tape when the optical storage tape is in the vicinity of the optical pickup units during read and/or write operations, the guiding wheel holding the optical storage tape on a planar circular path during read/write/tracking operations;
- the plurality of optical pickup units being disposed about an outer circumference of the guiding wheel, wherein a distance between the axis of rotation of the guiding wheel and each of the plurality of optical pickup units is substantially equal, such that the spacing between each of the plurality of optical pickup units and the optical storage tape held on the guiding wheel during read/write/tracking operations is substantially uniform;
- and
- a take-up reel for receiving the optical storage tape from the guiding wheel.

A method of storing data on an optical storage tape, the method comprising:
- providing a guiding wheel rotatably disposed on an axis of rotation;
- providing the optical storage tape to the guiding wheel such that the optical storage tape moves along an arced path when the optical storage tape contacts the guiding wheel;
- reading or writing data to the optical storage tape by a plurality of optical pickup units positioned about the guiding wheel, the guiding wheel holding the optical storage tape on a planar circular path during read/write/tracking operations;
- the plurality of optical pickup units being disposed about an outer circumference of the guiding wheel, wherein a distance between the axis of rotation of the guiding wheel and each of the plurality of optical pickup units is substantially equal, such that the spacing between each of the plurality of optical pickup units and the optical storage tape held on the guiding wheel during read/write/tracking operations is substantially uniform;
- and
- receiving the optical storage tape onto a take-up reel.
