摘要： A data storage device, data write method, and program to avoid extra power consumption and suppress a write error that may result from voltage variations. To write data onto a magnetic disk, a write circuit generates a write current that is to be supplied to a write head. The write circuit operates on a positive power supply voltage provided by a host computer, and on a negative power supply voltage generated by a programmable DC—DC converter mounted on a hard disk drive's card. The magnitude of the negative power supply voltage generated by the programmable DC—DC converter is varied in accordance with the temperature surrounding the magnetic disk. Further, the magnitude of the negative power supply voltage generated by the programmable DC—DC converter is varied in accordance with the magnitude of the positive power supply voltage supplied from the host computer.

摘要： In the case of magnetic head of magnetoresistance effect type whose breakdown voltage is as low as 0.3 V, it is impractical to ignore even a very small amount of static electricity that occurs during fabrication or use. In one embodiment, the desired magnetic head is produced by forming an SiO2 layer on a silicon slider, thereby forming an SOI substrate; forming on the SOI substrate circuits to protect a TMR element from overvoltage and a read-write circuit; forming field effect transistors from an Si semiconductor layer (formed by reduction of the SiO2 layer or epitaxial growth on the SiO2 layer); forming three electrodes (source, gate, drain) on the Si semiconductor layer; forming a Schottky diode by Schottky contact (metal) with the Si semiconductor layer; forming overvoltage protective circuits of aluminum wiring on the SOI substrate; and forming a TMR element.

摘要： An encoding system and associated method protect against miscorrection due to parity sector correction in, for example, an on-drive RAID system. The system adds a parity cluster block, which itself is a complete, C3-protected cluster. Having the cluster level, C4 level correction, by parity sectors, checked and verified by C3 checks that have high reliability level, as well as the capability for checking consistency of a cluster block, even in the presence of “jami” errors, makes this possibility unlikely. A scrub algorithm avoids read-modify-write operations by deferring the completion of the C2 and C3-ckecks until the storage device is idle.

摘要： The present invention provides a production process for a transparent heat-resistant resin, and further, a transparent heat-resistant resin and uses therefor, wherein the production process involves high dealcoholation conversion and a low content of residual volatiles in the resultant resin, and therefore can prevent foam or silver streak from occurring in the molded product, and further, facilitates melt-molding such as injection molding, and is fit for industrial production, and involves good efficiency. The production process for a transparent heat-resistant resin comprises the step of running a dealcoholation reaction of a polymer having a hydroxyl group and an ester group in its molecular chain to introduce a lactone ring structure into the polymer to obtain a transparent resin having the heat resistance, and is characterized in that the dealcoholation reaction is run in the presence of a solvent, and further characterized by further comprising a devolatilization step which is carried out jointly with the dealcoholation reaction.

摘要： A method and apparatus for minimizing performance degradation resulting from reassignment of data to alternate sectors as a result of a defect within the original sector. For example, when a request for writing data “a” into a sector A is made but the data is written into an alternative sector A′ in an alternative sector area X because the sector A is defective. Therefore, when a write request for writing data “b” into a sector B is made subsequently, re-assignment is performed to a sector B′ subsequent to the alternative sector A′. Similarly, a defective sector C for which a request for writing data “c” is made is re-assigned an alternative sector C′. Thus, the successive data a, b, and c are written into the successive sectors A′, B′, and C′ in the same alternative sector area X, minimizing performance degradation.

摘要： A disk storage device is disclosed for avoiding the instantaneous performance degradation as much as possible, and a method for processing a defective sector in such a disk storage device. There is executed a predetermined check related to a function of the disk storage device, preferably at least one of a read test, a write servo test, or a write test, when the disk storage device is in a waiting state where the disk storage device has no access from a host. The read test and write servo test are used to search for a defective sector on a disk and reassign the defective sector. The write test is used to indicate an abnormal condition of a head. Furthermore, the disk storage device includes a detector for detecting the waiting state, and a check logic for executing a predetermined check.

摘要： A method and system suitable for recording/reproducing audio-visual data on or from a hard disk or other storage media that can be accessed in random. Two streams, stream #1 and stream #2, are set. Then, 2000 sectors are set to the stream #1 and a specified number of sectors to the stream #2. By specifying this stream number (stream #1 or #2) and the audio-visual (AV) logical block address of the stream, the AV stream data recorded on the hard disk can be accessed. Each AV stream begins with zero and ends at the maximum AV stream LBA.
