    摘要： An information read/write device has a first processor for instructing a second processor to write information onto or read information from a recording medium. The recording medium has a random access memory module which allows both processors to read or write data to the memory module. The second processor controls a scanning module for the recording medium, a write signal processing module and a read signal processing module. The read/write device is easy-to-operate while using a minimum of electric power consumption with prevention against electromagnetic interference (EMI) making the invention suitable for use in hand-held devices.

    摘要： In a data recovery processing, the conventional overhead, primarily, latency due to a rotational recording media is removed. Secondary, in a signal processing or in a recording and reproducing apparatus, reliability of data reproduction is improved by repeatedly processing data. These processing are achieved that input signal, i.e., raw analog signal read from the recording media is digitized to be stored in a secondary storage such as a memory or a FIFO memory. The apparatus includes a signal processing circuit to repeatedly process the stored digital signal in the secondary storage. When detecting data, operation of the circuit is efficiently controlled by a change over detector parameters, in which characteristics for the detecting performance. Resultantly, data recovery processing speed is increased and reliability of data reproduced is improved.

    摘要： Embodiments of the invention provide a disk drive that is capable of determining the offset of a magnetic head position through simple and easy processing in a case where the shingle write method is adopted, and that is capable of increasing the accuracy. In one embodiment, a disk drive comprises: a recording medium including data tracks, each of which is formed with part of the data track being overwritten by an adjacent data track on the inner circumferential side or by an adjacent data track on the outer circumferential side; a head assembly including a write head for writing information to the recording medium, and a read head for reading out information from the recording medium; and a control device for controlling a position of the head assembly relative to the recording medium. Position-error detection signals whose phases differ from each other are repeatedly written to the recording medium in the track direction with written positions of the position-error detection signals being deviated from each other by a track pitch in the track width direction; and the control device controls a position of the head assembly on the basis of a burst signal read by the read head.

    摘要： Embodiments of the invention provide a disk drive that is capable of effectively controlling a side erase, which is one of the problems with the use of the perpendicular recording technology. In one embodiment, tracks on a recording medium are formed concentrically or spirally by overwriting a primary side track, which is either an inner track or outer track, onto part of a secondary side track, which is on the side away from the primary side track. A head unit is installed so that a magnetic head positioned at one end of the head unit relatively may move over the recording medium and that the yaw angle prevailing at an end track of the primary side on the recording medium may be substantially zero.

    摘要： Embodiments of the present invention efficiently format long sectors, without decreasing the performance, in a magnetic disk drive in which servo sectors are radially formed at regular intervals, and make full use of the ECC performance that is enhanced by the long sectors. In one embodiment, a data format in each zone on a magnetic disk is completed by a plurality of tracks N (N is an integer, which is 2 or more). The storage capacity per track of the outermost radius zone Z#1 is 150 kB. In this zone, long sectors each having a length of 32 kB are formatted with the number of tracks per format N#1=3. The storage capacity per track of the innermost radius zone Z#m is 80 kB. In this zone, long sectors each having a length of 32 kB are formatted with the number of tracks per format N#n=2.
