摘要： A magneto-resistance effect device (MR device) in which stable magneto-resistance characteristics may be achieved even if a layer of a soft magnetic material is reduced in width. The MR device includes a layer of a soft magnetic material 1, a rear end electrode 4, connected to one longitudinal end of the layer of a soft magnetic material 1, and a forward end electrode 5 connected to the opposite end of the soft magnetic material 1. On both ends of the layer of the soft magnetic material 1 are arranged magnetic domain stabilizers 2, 3 generating a bias magnetic field having a component parallel to the direction of width of the layer of a soft magnetic material 1. If the bias magnetic field sufficient to overcome the longitudinal magnetostatic anisotropy can be impressed, the direction of magnetization D.sub.f of the mono-layer soft magnetic material 1 is oriented in the direction of width. The electrical resistance of the magnetic domain stabilizers 2, 3 is selected to be larger than that of the soft magnetic material 1 for suppressing loss of the sense current i. The MR device 10 can be applied with advantage to a so-called vertical type MR head.

摘要： A magnetic disk device regularly monitors an abnormality in heads and, when detecting an abnormality in any head, transfers data in each cell corresponding to the head where the abnormality is detected to a replacement cell corresponding to another head. Then, in a management table, the magnetic disk device updates the logical address of the transfer-destination cell to the logical address of the transfer-source cell. Thereafter, the magnetic disk device deletes the data in the transfer-destination cell from the management table.

摘要： To solve the conventional problem in a disk drive unit that frequent interruptions be produced in a processor each time a head transits on a servo gate.To cope with the above-mentioned problem, a head drive unit 17 performs an off-track check using servo information read by the head 2 whenever the head 2 transits on each servo gate. Thus, an interruption processing required by the processor 16 is limited to the cases of either an operation completion interruption which is produced when a read/write operation is completed normally, or an error interruption which is produced on occurrence of the off-track or read error. This enables to reduce the number of interruption processing times performed in the processor 16, which results in reducing the load of the processor 16.
摘要翻译：为了解决磁盘驱动器单元中的常规问题，每当磁头在伺服门上运行时，在处理器中产生频繁的中断。为了解决上述问题，磁头驱动单元17只要磁头2在每个伺服门上运行，就使用由磁头2读取的伺服信息来执行偏离磁道检查。因此，处理器16所需的中断处理被限制为在读/写操作正常完成时产生的操作完成中断或者在出现偏离或读出时产生的错误中断的情况错误。这使得能够减少在处理器16中执行的中断处理次数，这导致处理器16的负载降低。
