Disk drive for circular self servo writing and spiral self servo writing using prewritten reference servo bursts

A disk drive is disclosed comprising a disk and a head actuated radially over the disk. An external servo writer is used to write reference servo bursts to the disk at a coarser radial resolution than product servo bursts. During a self servo writing operation, the reference servo bursts are processed to servo circularly to write a first set of product servo bursts to the disk. The reference servo bursts are also processed to servo spirally to write a second set of product servo bursts to the disk.

System and method for scalable data distribution

A system having a resource manager, a plurality of masters, and a plurality of slaves, interconnected by a communications network. To distribute data, a master determined that a destination slave of the plurality slaves requires data. The master then generates a list of slaves from which to transfer the data to the destination slave. The master transmits the list to the resource manager. The resource manager is configured to select a source slave from the list based on available system resources. Once a source is selected by the resource manager, the master receives an instruction from the resource manager to initiate a transfer of the data from the source slave to the destination slave. The master then transmits an instruction to commence the transfer.

Write reordering in a hybrid disk drive

A hybrid drive and associated methods increase the rate at which data are transferred to a nonvolatile storage medium in the hybrid drive. By using a large nonvolatile solid state memory device as cache memory for a magnetic disk drive, a very large number of write commands can be cached and subsequently reordered and executed in an efficient manner. In addition, strategic selection and reordering of only a portion of the write commands stored in the nonvolatile solid state memory device increases efficiency of the reordering process.

System and method for on-line, real time, data migration

A system and method for providing on-line, real-time, transparent data migration from an existing storage device to a replacement storage device. The existing and replacement storage devices are connected as a composite storage device that is coupled to a host, network or other data processing system. The replacement storage device includes a table which identifies data elements that have migrated to the replacement storage device. When a host system makes a data transfer request for one or more data elements, the replacement storage device determines whether the data elements have been migrated. If the data elements have migrated, the replacement storage device responds to the data transfer request independently of any interaction with the existing storage device. If the data elements have not migrated, the replacement storage device migrates the requested data elements and then responds to the data request and updates the data element map or table. When not busy servicing other requests, the replacement storage device operates in a background mode to migrate data elements so the data migration can occur concurrently with and transparently to system operations.

Recording medium, apparatus for forming the recording medium, and apparatus and method for reproducing the recording medium

Disclosed herein are a recording medium, an apparatus for forming the recording medium, and an apparatus and method for reproducing the recording medium. CPI (Copy Protection-related Information), identification information (CPI_Flag) indicative of recording or non-recording of the CPI, and / or a plurality of contents specific information (CSI) with different formats are recorded in a PIC (Permanent Information & Control data) zone of a high-density optical disc such as a BD-ROM (Blu-ray Disc-ROM). A formatting operation and mastering operation are performed under the condition that control data including the CPI, CPI_Flag and / or CSI is separated from main data. An optical disc device judges whether the optical disc has been illegally copied, with reference to the CPI, CPI_Flag and / or CSI read from the optical disc, and compulsorily stops a data playback operation upon judging that the disc has been illegally copied. Therefore, it is possible to effectively protect an optical disc from illegal copying, make an accurate and easy distinction between a legally made optical disc and an illegally made optical disc, and restrict reproduction of an illegally made optical disc.

Copy control using digital speed bumps

A digital media recorder and a method of controlling such are provided. During attempts to copy media content, sub-sequences are extracted from an input media sequence. A digital fingerprint of the sub-sequence is calculated and compared with at least one first reference fingerprint from a database. The outcome of the comparison determines the action to take in the further processing. Recording of the input media sequence on a media carrier is either allowed or obstructed, e.g. disallowed. In the case recording of the sequence is allowed, the database is updated with information that the digital media sequence has been recorded.

Multimedia search and indexing system and method of operation using audio cues with signal thresholds

A multimedia search and indexing system automatically selects scenes or events of interest from any media, i.e., video, film, sound for replay, in whole or in part, in other contexts. The entire audio track of a recorded event in video, film, sound, etc., is analyzed to determine audio levels within a set of frequency ranges of interest. Audio clip levels within the selected frequency ranges are chosen as audio cues representative of events of interest in the track. The selection criteria are applied to the audio track of the recorded event. An Edit Decision List (EDL) is generated from the analysis of the audio track. The list is representative of scenes or sounds of interest as clips for reuse. The clips are reviewed and accepted or rejected for reuse. Once selected, the clips are edited using industry standard audio and video editing techniques.
