  • Patent number: 8964369
    Abstract: In an example, a solid-state data storage system comprises a housing forming an enclosure; a plurality of trays within the enclosure of the housing; a plurality of non-volatile, rewriteable solid-state memory chips mounted to flexible circuit substrates within each of the trays; and a controller configured to apply a power-sequencing scheme that supplies power to active flexible memory strands.
    Type: Grant

  • Publication number: 20080198487
    Abstract: The disclosure is directed to techniques for transferring data files representing a digital motion picture to a motion picture system within a theater in a single step. More specifically, the techniques allow a user to press one button to initiate the transfer, or upload, of a plurality of data files stored on a data tape to a predetermined location within a data storage device within the theater. The single input from the user frees the user from completing the plurality of steps needed to manually select a desired data file from the data tape and find the location to transfer the data file. Instead, the data tape or user system may automatically identify the entire plurality of data files and the predetermined location at which to store the plurality of data files. The techniques facilitate the distribution of motion pictures from motion picture studios to theaters using magnetic tape media.

  • Patent number: 7342738
    Abstract: The Invention Provides a Positioning System for a Linear Data Storage Medium, Such as magnetic tape or other data storage medium in which data is stored on parallel data tracks that extend along a length of the medium. The invention makes use of multiple actuators to control the positioning of sliders carrying read and write elements, e.g., separate sliders carrying the read and write elements, relative to the data storage medium with multiple degrees of freedom. The multiple degrees of freedom may include two or more of a vertical position, a horizontal position, a transverse position, an azimuth position, a zenith position, and a yaw position. In this manner, the invention can improve head-to-track alignment of read heads and write heads with linear data storage systems having very small track pitches, such as track pitches approximately 1 micron and especially less than 1 micron.
