    摘要: A dual-path optical recording medium and an apparatus for accessing such are disclosed. The dual-path optical recording medium includes a substrate, an intermediate recording layer, a holographic recording layer and a dichronic mirror layer. The intermediate recording layer is a rewritable data storage layer with a relatively low storage capacity. The holographic recording layer is a write-once data storage layer with a relatively high storage capacity. The dichronic mirror layer is located between the holographic recording layer and the intermediate recording layer. The apparatus for accessing the dual-path optical recording medium includes a first light module capable of generating a first laser light, and a second light module capable of generating a second laser light.

    摘要: A velocity calculator performs high-order calculations of servo frame velocities of a storage media, particularly tape and disk. The velocity calculator employs a servo frame indexing module for generating a first-order preceding servo frame velocity signal indicative of a first-order calculation of a preceding servo frame velocity including a first-order preceding servo frame error term based on first-order current servo frame velocity signal indicative of a first-order calculation of a current servo frame velocity including a first-order current servo frame error term. The velocity calculator further employs a velocity estimating module for generating a higher-order current servo frame velocity signal indicative of a second or higher order velocity calculation of the current servo frame velocity including a higher-order current servo frame error term based on the first-order preceding servo frame velocity signal and the first-order current servo frame velocity signal.

    摘要: A Redundant Array of Independent Devices uses convolution encoding to provide redundancy of the striped data written to the devices. No parity is utilized in the convolution encoding process. Trellis decoding is used for both reading the data from the RAID and for rebuilding missing encoded data from one or more failed devices, based on a minimal, and preferably zero, Hamming distance for selecting the connected path through the trellis diagram.

    摘要: The present invention provides a method and system for performing file recovery in a computer system coupled to a storage subsystem, wherein a data scrubbing process analyzes said storage subsystem for potential or existing storage errors. The method includes: receiving a report from said data scrubbing process describing said errors, including logical block addresses (LBAs) of storage locations containing errors; interacting with a file system created on logical unit numbers (LUN) provided by said storage subsystem in order to identify file information pertaining to the erroneous LBAs; moving the file pertaining to said erroneous LBAs to a different storage location; updating pointers to said file; in case of an unrecoverable, accessing a backup copy of said file from a backup location; if a predetermined degree of error severity is exceeded, creating an additional copy of said file; and updating the pointers to said file managed by the file system, respectively.
