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.

The present invention relates to a recording medium containing moving picture data and additional information thereof and to reproducing method and apparatus of the recording medium. The present recording medium has script files including additional information about moving picture data, e.g., scene descriptive text and introduction of characters, etc. In addition, information linking each script file with a section of moving picture data to be presented with contents of the script file is included in a link data file or is contained in a filename of the script file. In reproduction of the recording medium, a script file linked with presently reproduced moving picture data section is determined and searched for based on the link data file or every filename of the script files, and contents of the found script file are presented together with the presently reproduced moving picture data. Furthermore, previously presented additional information is removed depending on data or filename of the found script file.

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.

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.

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.

A system that allows consumers to manage content and create audio/video presentations in a small portable media device, and to share media files with other users of small portable media devices, without requiring access to a computer.

To solve the problem inhibiting the copyright protection caused by reason that there are no means for restricting the number of backups to other media, which makes it impossible for a copyright owner to specify the allowable number of backups for the content of “Copy One Generation”, disclosed herein is a digital information recording and reproducing method. The method is so configured that: a first piece of digital information and copy control information of the first piece of digital information is received, wherein the copy control information is for controlling the recording of the first piece of digital information on a recording medium; and when the received copy control information is Copy One Generation indicating that only one generation copy of digital information is allowed, a plurality of the first pieces of digital information are recorded on a first recording medium as the first piece of digital information and a second piece of digital information, wherein the first piece of digital information is different in format or in bit rate from the second piece of digital information.

An imprint stamper for manufacturing a recording medium includes a first transfer region which corresponds to a servo region of a recording medium using a sector servo system and has a pattern with a plurality of quadrilateral recess or protrusion portions formed in a surface thereof, and a second transfer region which corresponds to a data region of the recording medium and has a pattern with a plurality of dots of recess or protrusion portions arrayed in a form of a hexagonal lattice in a surface thereof.

Methods and apparatuses for protecting against copying of content recorded on optical recording media are provided. An area of an optical recording medium is designated to be ignored by a standards-compliant optical media player reproducing content recorded on the optical recording medium. Unreadable data is written to the designated area which is ignored by the standard-compliant optical media player. When an optical medium drive attempts to read the unreadable data in order to perform a one-to-one copy process on data recorded on the recording medium, the optical medium drive is unable to complete the one-to-one copy process.

A magnetic recording apparatus comprises a magnetic field impression unit, a current supplying unit and a controlling unit t. The magnetic field impression unit impresses a magnetic field to a magnetic recording medium. The current supplying unit supplies a current to the magnetic recording medium. The controlling unit makes the current supplying unit supply the current to the magnetic recording medium while making the magnetic field impression unit impress the magnetic field to at least a unit of a magnetic recording unit of the magnetic recording medium. Thus, a information is recorded magnetically by making a direction of a magnetization of the magnetic recording unit of the magnetic recording medium in a predetermined direction.

Management information is embedded by directly controlling media with a date hiding technique. A system which accesses (regenerates or records) media data by using the management information is controlled based on this management information, and according to the contents of the management information, the access to media data is inhibited.

The content of a hard disk drive or the like information storage media that includes content stored in a host protected area (HPA) or reserve area of the hard disk is duplicated using hard disk drive duplicating machinery. The duplication process includes the steps of detecting the presence of a HPA on a source drive, and if detected, generating an HPA are of the same or of a sufficiently accommodating size on the target disk drive. Information from the source HPA drive to the thus created HPA area of the target-drive. The remaining content from the source drive is written to an available section of the target drive. The invention is thereby able to detect whether a source drive has a HPA, create an HPA on the target drive, and to copy the content of the source HPA to the HPA on the target device to ensure a proper duplication of the target drive.
