摘要： A speaker system for a picture receiver provides for lessening of the casing width of the picture receiver while assuring highly uniform acoustic characteristic at listening points in a sufficiently broad range. The speaker system for picture receiver and its speaker installing method comprises a first speaker for reproducing medium and high range sound at the right and left of the screen of a picture receiver and a second speaker for reproducing medium and low range sound under the screen, wherein the speaker system is set in such place that when a listening point is set at a position a first distance apart from the picture receiver and within a second distance from the front axis at the center of the right and left of the screen, the distance from the first speaker to the listening point is R1, the distance from the second speaker to the listening point is R2, and the crossover frequency is f, then R1, R2 and f satisfy the specified relative formula.

摘要： In the present invention, for each set of blocks [#(0) to #(N−1)] storing update data, a history block [#(N)] storing an update state value, for example, a generation, time or check code, showing an update state is provided, constituting a set of management data as a check object. When writing update data on a disk, a new update state value is calculated for the same set of management data and stored in memory as update state confirmation value. The new update state value is also set as write data in the history block in the same set of management data, and the entire of the set of management data including update data and update state value are written onto a disk. The history block is read and disk write omissions are detected by comparing the update state value and the update state confirmation value stored in memory.

摘要： A RAID controller accesses an access request area on logical volumes distributed and stored on a plurality of physical disks according to a disk access request from a host. The controller has a plurality of management modules which are in-charge of plurality of the redundant groups respectively and issuing a logical format request for each area of said logical volume by referring to a management table for managing progress information of the logical format processing. Each management module has a plurality of the management table for being in-charge of said plurality of redundant groups and a queue for queuing the disk access request. The management module, according to the disk access request, judges whether all the access request areas have been logically formatted referring to the management table.

摘要： A storage controller executes logical format to enable host access to a physical disk, where the logical format of a physical disk is executed without waiting for host access. The storage controller comprises a logical format management module having bit map memory for managing progress information on format processing of a logical volume, and a lower layer module which accesses a physical disk according to the request of the management module. The management module judges whether all the access areas have been formatted referring to the bit map memory, requests the disk access to the lower layer module if judged as formatted, while, issues a logical format processing request before the disk access, queues the disk access request to the queue if not formatted, further searches the unformatted area from the bit map memory, and issues a logical format processing request if no disk access request exists in the queue.

摘要： In case an error statistics of one of the disk drives exceeds a predetermined threshold, the disk is determined as a suspect disk drive. A recovery mode is set successively. During the time when a setting of the recovery mode is in progress and no access is made from a host 16 in this time, the address range of the suspect disk drive is specified. At the same time, a processing is started in that the data of the suspect disk is copied to a spare disk 34 sequentially to recover the data. The data of the suspect disk drive is copied to the spare disk drive 34 to recover the data when the address range of the suspect disk drive does not correspond to the write failure address range of a management table 48. The data of a normal disk drive is copied to the spare disk drive 34 to recover the data when the address range of the suspect disk drive corresponds to the write failure address range of the management table 48. Upon the completion of the recovery of the data, the suspect disk drive 32 is separated and replaced with the spare disk drive 34.
