摘要： Disclosed is a disk storage apparatus to control writing to a storage medium having a storage area to which a first address space is allocated and whose transfer rate spatially changes, including a command reception section and control section. The command reception section receives a write command from a host apparatus and containing an address of the first address space. The control section performs control to divide the storage area into zones, pre-define a second address space where blocks are successively allocated to the zones from a beginning address of the first address space, replace, for each of the write commands received by the command reception, an address of the first address space contained therein with an address of the second address space, select one of the zones as a write target zone by cyclical changing, and perform a writing process to the storage medium for each selected zone.

摘要： A recording/reproducing apparatus is provided which can write continuously a file of large-capacity at high-speed. A record area of HDD is provided with a disk cache area for temporarily storing data to be written. The disk cache area is defined as a area that is not used by a host apparatus (3) in an LBA space, and the disk cache area is disposed in an area with a high transfer rate such as an outer circumferential area of a disk (10). A file transferred from the host apparatus (3) is written in the disk cache area, and the file is transferred from the disk cache area to a usual user area during an idle period to release the disk cache area and prepare for next transfer data write.

摘要： A soft error correction algebraic decoder and an associated method use erasure reliability numbers to derive error locations and values. More specifically, symbol reliability numbers from a maximum likelihood (ML) decoder as well as a parity check success/failure from inner modulation code symbols are combined by a Reed-Solomon decoder in an iterative manner, such that the ratio of erasures to errors is maximized. The soft error correction (ECC) algebraic decoder and associated method decode Reed Solomon codes using a binary code and detector side information. The Reed Solomon codes are optimally suited for use on erasure channels. A threshold adjustment algorithm qualifies candidate erasures based on a detector error filter output as well as modulation code constraint success/failure information, in particular parity check or failure as current modulation codes in disk drive applications use parity checks. This algorithm creates fixed erasure inputs to the Reed Solomon decoder. A complementary soft decoding algorithm of the present invention teaches the use of a key equation solver algorithm that calculates error patterns obtained as a solution to a weighted rational interpolation problem with the weights given by the detector side information.

摘要： A method and apparatus for efficiently encoding an ECC block for improving writing performance of a storage device using an ECC block format having a linear code such as a Reed-Solomon code is described. When the data f1 of a part of data sectors among a plurality of data sectors which form an ECC block F1 having a PO portion q1 formed with a linear code such as a Reed-Solomon code is updated with data f2 to obtain the ECC block F2 having the updated PO portion q2, the ECC block F1+F2 of the exclusive OR of the source data part of the ECC block F1 before updating and the ECC block F2 after updating is taken, so that the XOR of f1 and f2 (i.e. f1+f2) of the data f1 to be updated and the updated data f2 is obtained. The XOR of non-updated data sectors is 0. Then, when the ECC block F1+F2 of the XOR is encoded, the PO portion in the form of the XOR q1+q2 is obtained in accordance with the linearity of the Reed-Solomon code. Thus, q2 can be gained based on the exclusive OR of q1+q2 and q1, resulting in the ability to write out the data more efficiently.

摘要： A computer system is implemented by a plurality of electronic modules having different parts, cascaded in the vertical direction and each having a similar configuration. Adjacent two of the modules are coupled by rotating a pair of lock dials to a lock position at which the locked pin of the protrusion is engaged with a helical groove formed in the lock dials. A common signal bus is formed by engagement of a plug and receptacle at the locked position. The adjacent modules are separated by rotating the lock dial to an open position.
