    Abstract: A data storage and retrieval system includes a head carriage unit having multiple heads disposed at a working surface and a tape drive unit configured to move the tape past the working surface of the head carriage unit in a direction substantially parallel to a tape length. The heads are configured to write primary data tracks to or read primary data tracks from the tape as the head carriage unit rotates and the tape moves past the working surface, the primary data tracks having an arcuate shape and extending substantially along a tape width. The heads are also configured to write at least one secondary data track to or read at least one secondary data track from the tape as the head carriage unit rotates and the tape moves past the working surface, the at least one secondary data track extending substantially along the tape length.

In order to make each reflected light become incident upon each photodiode (52M, . . . ), a case (72) and a bracket (78) are separated from a chassis (70), and support the focus adjusting lens (50) and the photodiodes (52M, . . . ) respectively. The case (72) and bracket (78) are made so that they can be fixed to the chassis (70) at optional positions in a predetermined area along a direction of the optical axis (66). While the case (72) and bracket (78) are moved along the optical axis (66) direction, positions along the optical axis (66) where the reflected light beams are allowed to enter the photodiodes (52M, . . . ) are searched and the case (72) and bracket (78) are fixed to the chassis (70) at the searched positions.

    Abstract: This invention provides a method of acquisition of binary information that has been stored physically in a periodic storage medium. The method, referred to as matrix-method deconvolution (MMD), is useful for use with optical storage media using an optical addressing system that reads and writes binary information in a periodic array of nano-particles. With this MMD method, the density of existing memory systems can be boosted to between 10 and 100 Terabytes of data per cubic centimeter. This matrix-method deconvolution method compensates for the effects of the optical addressing system's point spread function. Prior knowledge of a system's point spread function and inter memory-center spacing is used.
