摘要： A disk system that conducts diagnoses of magnetic heads at regular or irregular interval to detect occurrence of unwritable failure. The history of regions on magnetic recording media where write operations took place is managed and a region where an unwritable failure occurred is specified. Data that corresponds to the unwritable failure is recovered by taking advantage of the redundancy of a RAID system. The disk system includes a unit that, upon reading data, checks whether the data to be read was written on the magnetic recording media through a normal write function. Through this, old data is prevented from being sent to host devices as a result of unwritable failure, and unwritable failures can be dealt with without increasing the processing time to detect unwritable failures.

摘要： A multimedia direct access storage device and a method for transferring source program signals representative of a compressed digital multimedia program to and from the direct access storage device are disclosed. A multimedia program is transmitted from a multimedia server as a custom ordered series of discrete program segments and received by the multimedia direct access storage device, which buffers the compressed program segments for subsequent presentation on a local display monitor. The multimedia direct access storage device is preferably incorporated as a component of a local set-top control system for buffering a predetermined number of compressed program segments received from the multimedia server, some of which may be non-sequentially ordered and others of which may be sequentially ordered. A novel formatting methodology provides for the sequential presentation of the program segments asynchronously distributed on one or more data storage disks disposed in the direct access storage device. A user-definable presentation control window for performing local VCR-type presentation control functions for the portion of a multimedia program buffered in the direct access storage device is also provided through the novel formatting methodology. The novel formatting methodology also provides concurrent presentation and buffering of program segments received from the multimedia server for on-demand viewing of a selected multimedia program.

摘要： The present invention is related to methods and systems for accessing multimedia data stored on a disk array to ensure that the transfer rate does not fall below a selected minimum transfer rate independent of where the multimedia data is stored on the disk array. In one embodiment, the sizes of blocks accessed are varied and the direction of access is selected to enhance read performance. A plurality of blocks are read whose sizes vary linearly as data is being read from a first disk in a backward direction, from an inner diameter side of the first disk, towards an outer diameter of the first disk. Blocks are read from a second disk in a forward direction, towards an inner diameter of the second disk.

摘要： A system concept and the components integrated therein for storing useful and control information as well as feature items, general components for data flow control of all components integrated in the system concept as well as special components for data flow and process control of interface systems for laser-beam recorders permit handling of useful and control information as well as feature items independently of physical music/data carriers within premastering and the production of glass masters (mastering) in CD plants. All the various types of information are stored in on-line compatible mass storages and automatically transferred into the sectors calling for the information concerned by general data flow control components. Requests for information can be generated manually or automatically. The time needed to transfer to the requesting sectors or machines is shortened, the premastering expense reduced, the mastering actions automated with the aid of special control components and considerably speeded up as compared to conventional methods by using a network as the carrier medium.

摘要： Video data in the form of a plurality of digitised frames, is stored on a plurality of magnetic disks. Each image frame is striped across a plurality of disks and redundant parity information, derived from the stripes, is written to an additional disk. Disk failure is detected and in response to this detection missing data is regenerated from the parity information. This allows the transfer of video data in real time to be maintained for output so that the system remains operational. While data is being read in real time, derived-from regenerated data, the regenerated data is written to an operational disk, thereby reprotecting the data in the event of a subsequent failure. Frame supplied to output are labelled as being protected or unprotected and application programs may respond to this status information as considered appropriate.

摘要： A data storage control method and a data storage control apparatus are provided which mitigate the access concentration on a particular storage unit while maintaining both high-speed operation and system redundancy. To be more specific, driver blocks installed on client machines respectively each function as a controller for dividing source data into blocks and storing these blocks in a plurality of storage units in a distributed manner. These blocks include primary data blocks for normal use and secondary data blocks which are alternatively used if the primary data have inaccessible blocks. The controller, when storing the secondary blocks into the plurality of storage units, stores last j blocks in place of first j blocks in every N blocks, N being equal to the number of storage units, and sequentially updates the value of j from 1 to Nnull1 for every N blocks.

摘要： In a data recording and reproducing apparatus (10), according to a release instruction from a server controller (30) added to a PLAY_OPEN command for requesting preparation of reproduction of arbitrary data, management information is changed so that an area occupied by reproduced data of the data in the on-producing file becomes an area where new data can be recorded anytime while the file is reproduced. As a result, for example, in the case where plural data are recorded, before the reproduction of the on-reproducing file is completed, the data recording area occupied by the reproduced data is changed into an area where new data can be recorded by efficiently utilizing recording areas in a data accumulation section (13) if on-producing file exists.

摘要： A system (100) has a storage medium (110) that contains a number of storage units (108). A multimedia title is stored in the storage medium (110) as a number of blocks, whereby some of the blocks are stored multiple times such that different storage units (108) contain a copy of that block. Retrieving blocks from the storage medium (110) for supply to a user is executed in cycles and the system has for some of the blocks the freedom to choose from which of the storage units (108) the block is retrieved in order to balance the load on the storage units (108). Furthermore, the system (100) is arranged to look ahead a number of cycles to determine what blocks in the near future are necessary and to retrieve these future blocks earlier if the storage units are not yet fully occupied. The additional freedom to schedule retrieval of a block at earlier moments in time provides a further mechanism to balance the load on the storage units.

摘要： Inputted video signals are highly compressed in a high-compression processing means and the compressed signals are saved in a high-compression system processing means, and the video signals lowly compressed in a low-compression processing means and the compressed signals are saved in a first and a second recording means with separating them according to using frequency. The saved videos in the high-compression system processing means are edited and an executing sequence list showing their executing sequence is formed, and a video signal having a high using frequency is outputted from the first memory means which has a small storage capacity (thus, easily accessible), based on the executing sequence list.
