    Abstract: A disk array device maintains data reliability with few performance degradation problems. In a RAID 4 or RAID 5 disk array device, redundant data created during disk degeneration with a device control module is transferred to a memory of a subsystem control module. The memory is backed up with a battery. The redundant data is held in memory until a writing operation to disk drives is completed. Then, when recovering after a momentary power supply interruption, the write data and parity data stored in the memory are written out without writing data from the disk drive. When recovering after a momentary power supply interruption and the disks are normal, the redundant same-group data is read from disk drives other than those on which the data that is to be written and the parity are stored and based on those and the write data, new redundant data is created and written to the object disk.

    Abstract: A data recording medium suitable for an optical disk such as DVD is disclosed. The data recording medium has a plurality of sectors. The sector has a header area to store address information of the sector, a gap area for power calibration of a laser beam used for data recording, a data recording area to store a plurality of modulated codes obtained by modulating the data, a postamble area located immediately after the data recording area, and a buffer area to separate sectors. The modulated code includes information to demodulate a modulated code located immediately before each modulated code. The postamble area stores information to demodulate the final demodulated code in the data recording area. A data pattern stored in the postamble area includes synchronization pattern, and is determined based on a DSV of the data pattern, or satisfying the run length limitation.

    Abstract: To provide a memory-writing device which can simply and reliably write desired data to a nonvolatile memory of an electronic device, connection is made with an ECU to perform write processing to write write data from the memory-writing device to a flash ROM by copying a write-control program from the external portion to a RAM and executing the write-control program, and by sequentially sending the foregoing write-control program and write data to this ECU together with sending, at a predetermined timing, write-control information required for the ECU to execute the write-control program, the write-control program and the write-control information are stored in a freely attachable and removable first ROM and the write-control information stored in the first ROM is read and sent to the ECU at a memory-rewriting device to cause the write processing to be performed in the ECU. According to this device, an ECU of differing specifications can be supported merely by exchanging the first ROM.

    Abstract: In an optical disc, an ID field contains a plurality of address information, and is preliminarily recorded in convex and concave signals, and is composed of two sets offset by about ½ track pitch toward the internal or external track direction adjacent to the guide track, an information recording field is composed of grooves and lands oscillating at a single frequency in the radial direction, and the grooves and lands alternate in every revolution of the guide track. When w bits of information are included in one period of oscillation, an information unrecorded field between the ID field and information recording field is arranged to have a length of w/10 bits or more and/or w bits or less, and therefore, when recording continuous information data such as video data, it is possible to record continuously by generating a clock securely from the oscillating signal, and moreover, the format efficiency is improved, so that a format of a larger capacity is achieved.

    Abstract: The present invention is aimed at providing an optical disk, an optical disk device, and an optical disk reproduction method, for allowing for stable and efficient reading of address information. The optical disk includes a plurality of tracks each divided into a plurality of recording sectors. Each of the recording sectors includes a header region. The header region includes address information for identifying the position of the corresponding recording sector and address synchronous information for identifying the recording position of the address information for bit synchronization. The address information has been modulated using a run length limit code of a maximum inversion interval of Tmax bits (Tmax is a natural number), and the address synchronous information includes two patterns of which inversion interval is (Tmax′+3) bits or more, so that the reproduced signal of the address synchronous information is distinguished from the reproduced signal of other information.
