    摘要： A head gimbal assembly that includes a bleed resistor applied over a specified area of the reader, writer and ground leads in order to protect from ESD damage is disclosed. The present invention address the need for an ESD protection system that includes a consistent and secure connection with leads, that does not contaminate the drive environment and applies a consistent resistivity to both the reader and writer element by providing a head gimbal assembly with strategically placed bleed resistors that will protect the read element from transient charge produced any time during the fabrication, assembly, testing and shipment of the disc drive.

    摘要： A rotary head apparatus includes a rotary drum having two magnetic heads mounted thereon. Each magnetic head has a recording-medium opposing surface curved in two convex shapes extending towards the outside of the drum, one along the longitudinal cross section of the magnetic head extending across the centerline laterally dividing the magnetic head into two parts so as to be orthogonal to the sliding direction of the recording medium, and the other along the lateral cross section orthogonal to the centerline. The apex of the lateral cross section is gradually displaced from the centerline as distancing itself from the center of the surface in the longitudinal direction and in the opposite direction to the above displacement as distancing itself from the center in the reverse longitudinal direction. Each displacement of the apex laterally away from the centerline in a sliding area of the recording medium is at most 2 μm.

    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： A disk array device that prevents the processing of the host device from being interrupted or delayed by drive idle seek, idle seek being executed by all the drives at approximately fixed intervals. The disk array device predicts the approach of the scheduled times to start idle seek of each of the disk drives 23, 23, . . . and exercises control so that, within the same parity group, idle seek is not executed by two or more drives 23, 23, . . . at the same time. Within the same parity group, one of the drives whose idle seek scheduled start time is approaching is considered in advance to be executing idle seek and hence data access is denied beforehand. When a data read request with respect to the drive 23 that is considered to be executing idle seek is received, the required data is recovered by reading data from all the other drives 23, 23, . . . belonging to the same parity group.
