摘要： A magnetic head includes a pole layer, and an encasing layer having a groove that accommodates the pole layer. A manufacturing method for the magnetic head includes the steps of forming a nonmagnetic layer that will later undergo formation of the groove therein and will thereby become the encasing layer; forming the groove in the nonmagnetic layer so that the nonmagnetic layer becomes the encasing layer; and forming the pole layer such that the pole layer is accommodated in the groove of the encasing layer. The nonmagnetic layer is formed of Al2O3. The step of forming the groove in the nonmagnetic layer includes the step of taper-etching the nonmagnetic layer by reactive ion etching with an etching gas containing at least BCl3 and N2 among BCl3, Cl2 and N2.

摘要： A thin film magnetic head has a configuration in which a main magnetic pole film having a magnetic pole end portion on a medium opposing surface (ABS) side facing a magnetic disk, a write shield film facing the magnetic pole end portion so as to form a recording gap film on the medium opposing surface side, and a thin film coil wound around at least a part of the write shield film are laminated. Further, the thin film magnetic head has an upper yoke magnetic pole film whose size is larger than that of the main magnetic pole film at a part more distant from the ABS than the recording gap film, and this upper yoke magnetic pole film is bonded to the side of the main magnetic pole film close to the thin film coil. In the upper yoke magnetic pole film, an end portion on the ABS side is retracted in a direction apart from the ABS in accordance with an increase in film thickness which is measured from the surface of the main magnetic pole film.

摘要： Data transferred from a host computer to a memory device is written into sectors whose addresses in a memory area are decoded by a decode table. Old data to be updated by the above data is erased or marked with erase flags. At a predetermined point of time, in order to create free areas, necessary data is evacuated to a primary memory media and unnecessary data indicated by erase flags is erased by a unit of predetermined memory size. Part of the memory media which has become defective is marked with a defect flag, and is replaced by an alternate area. In doing so, the decode table is rewritten to arrange the memory area.
