摘要： A source data stream is distributed to two or more compression paths that provide a corresponding number of compressed data streams that are concurrently encoded onto a recording medium as a set of media tracks. In one embodiment, buffer space within each compression path is monitored and the source data stream is directed to a ‘starved’ compression path. Metadata is inserted into the compressed data streams to facilitate reconstruction of the source data stream from the compressed data streams. The source data stream may be reconstructed by concurrently decoding the media tracks, decompressing the compressed data streams to a corresponding set of decompressed data streams, and merging the decompressed streams into an output data stream as directed by the metadata. The present invention overcomes the bottlenecks and other issues previously associated with context-based compression within digital media recording systems.

摘要： Disclosed are a method and a detector for adaptively detecting servo gaps in a timing based servo pattern prerecorded on a variable velocity media. The timing based servo pattern has groups of repeated pairs of non-parallel transition stripes arranged in bursts, the bursts separated by servo gaps whose length is variable. A servo system sensor senses the transition stripes in the longitudinal direction of the media. A group interval detector coupled to the sensor detects the timing interval between the same slope transition stripes of two sequential groups of bursts. A divider divides the detected group timing interval by a predetermined divisor to provide a divided timing interval gap detection threshold. A sequential stripe interval detector coupled to the sensor measures the timing interval between stripes, and a comparator compares the divided timing interval and the timing interval, identifying a servo gap upon the measured timing interval at least equaling the gap threshold. The detector responds to “valid” signals which indicate the validity of the detected group timing interval, repeating operation of the divider to update the gap threshold, and repeating operation of the comparator with the updated gap threshold to continue to identify the servo gaps.

摘要： A tamper-resistant Hard-WORM data storage system and a magneto-optical storage disk therefor is disclosed. The disk has a plurality of sectors thereon containing one or more uniquely formatted fields to provide an indication that the disk is a Write-Once Read Many (WORM) disk. A motor is provided in the storage system for rotating the disk at an operational rotational speed and a laser read/write (R/W) head unit is provided for reading and writing information in the sectors. A read/write (R/W) control unit within the storage system controls read and write operations on the disk in response to commands from an external data processing device, such as a computer. The R/W control unit is adapted to decode the one or more uniquely formatted fields in order to read and correctly interpret information contained therein. In an additional aspect of the disclosure, the R/W control unit disables erase operations in sectors containing uniquely formatted fields but allows such operations in sectors that do not contain such fields in order to permit calibration testing and the maintenance of media defect lists, first available sector lists and the like.

摘要： A method and system for handling literals in a Lempel-Ziv data compression system. The literals are arranged in a storage array in an MRU/LRU format in a defined sequential MRU/LRU order, with shorter MRU/LRU reference codes assigned to the MRU literals and longer MRU/LRU reference codes to the LRU literals. Upon receiving an input literal, a selector selects the literal and a reference encoder provides the assigned MRU/LRU reference code for the literal as the output. The literals are then rearranged. An incrementor responds to the literal selection, by incrementing downward one location in the sequential order, all the literals in the storage array from the top of the MRU order to the one of the literals in the order immediately preceding the selected literal, and the selector moves the selected literal to the top of the MRU order.

摘要： Disclosed is a magnetic tape media having addressing data information superimposed on prerecorded track following servo information. The servo information is recorded in magnetic flux transition patterns defining at least one longitudinal servo track. A servo burst pattern of at least two repeated pairs of non-parallel magnetic flux transitions is provided, at least one of which transitions is slanted or otherwise continuously longitudinally variable across the width of the servo track. At least two transitions of the repeated pairs are shifted longitudinally with respect to other of the transitions, the shifted transitions comprising the superimposed addressing data information. Also disclosed is a magnetic tape media having prerecorded combined servo and data information recorded in repeated pairs of magnetic flux dual transitions, at least one of the repeated pairs of dual transitions having a different width with respect to other of the transitions, the different width transitions comprising data information.

摘要： Access to encrypted data on a removable computer media such as a computer tape is controlled via a uniquely-structured header on the medium having a symmetrical key wrapped by asymmetrical encryption plus a public key associated with the asymmetrical encryption. The data on the medium is encrypted using the symmetrical key. Prior to automated reading of the data by a reader, a challenge is issued to a host system including the public key and preferably a nonce value. The host responds by signing the nonce using a private key associated with the public key in order to prove it has rights to decrypt the data. The symmetrical key is unwrapped using the private key, and finally the unwrapped symmetrical key is used to decrypt the data on the medium, thereby allowing automated reading of the tape data without the need or risk of two administrators sharing a symmetrical key value.

摘要： Disclosed is a technique for updating a read-detect channel. A signal is processed in a read-detect channel that has one or more programmable registers. While signals continue to be processed by the read-detect channel, it is determined with a channel auxiliary processor whether to dynamically replace values of the one or more programmable registers. When it is determined that values of the one or more programmable registers are to be replaced, a channel auxiliary processor determines values for the one or more programmable registers and replaces existing values for the one or more programmable registers with the determined values.
