Abstract:
1. 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.
