摘要： Embodiments of the invention prevent a decrease in magnetization or demagnetization from occurring to recording magnetization regardless of a direction in which a stray field is applied. In one embodiment, an apparatus for data storage system comprises a head having a magnetic field shield in the vicinity of a main pole, and a cover of the device, using a constituent material with a magnetic field shielding effect, across the cover, or at part thereof. When a stray field in a direction perpendicular to a recording medium is applied, the effect of the magnetic field is alleviated by the magnetic field shield installed in the vicinity of the main pole. In such a case, it need only be sufficient to form the magnetic field shield in a shape optimum for removing the stray field in the perpendicular direction only. When a stray field in a direction horizontal in relation to the recording medium is applied, the magnetic field acting on the recording medium is removed by the cover of the device comprising a magnetic component.

摘要： A magnetic disk apparatus has a rail support which supports guide rails for guiding a carriage on which heads are mounted. The rail support is positioned outside a magnet of a voice coil motor and mounted on a frame. The guide rails are disposed so as to extend across a cavity in the rail support and have their opposite end portions attached to the rail support. The guide rails do not vibrate even if the voice coil motor receives a reaction during head seeking, whereby the head positioning accuracy can be improved and the storage capacity can be increased. The rigidity of the guide rails is increased by supporting the opposite ends of the guide rails. This structure and a coaxial arrangement of a motor coil allow the overall length of the carriage and, hence, the overall size of the apparatus to be reduced.
