摘要： In a magnetic disk apparatus, a function of shielding a magnetic head is improved while maintaining the form factor with an inexpensive structure. In one embodiment, a magnetic disk apparatus has a magnetic disk, a magnetic head that records or plays back information, a magnetic head support mechanism supporting the magnetic head, a positioning mechanism that moves the magnetic head in a radial direction of the magnetic disk to place the head in position, an enclosure made of a nonmagnetic material, and a shield member made of a magnetic material. The magnetic disk, magnetic head, magnetic head support mechanism, positioning mechanism, and shield member are housed in the enclosure. The shield member has an upper shield located above the magnetic head and extending over the range of movement of the magnetic head, a lower shield located on the opposite side of the surface where the magnetic head exists and extending over the range of movement of the magnetic head, and a connecting portion connecting an outer side end portion of the upper shield and an outer side end portion of the lower shield near the outer fringes of the magnetic disk.

摘要： Embodiments of the invention enable the flying of a slider to be lowered and increase recording density with a simple configuration in a magnetic disk apparatus. In one embodiment, a magnetic disk apparatus comprises a magnetic disk including tracks for recording data; a magnetic head slider disposed with a magnetic head that flies over the rotating magnetic disk and records data to, or plays back data from, the magnetic disk; and a control device that controls the operation of the apparatus. Slider flying height data that vary inside the tracks are prerecorded in the tracks of the magnetic disk. The control device controls the operation of the magnetic head slider with respect to the magnetic disk on the basis of the slider flying height data recorded in the tracks.

摘要： A head element is made into contact with the surface of a recording medium so as to realize a float-up degree of 5 nm. Accordingly, a slider incorporating the head element for recording and reproducing data to and from the recording medium is provided thereon with a plurality of pads having step parts, and one of the plurality of pads, on which the head element is mounted, has a height which is less than that of the other pads. Thus, the pads other than the pad on which the head element is mounted are floated up while the pad on which the head element is mounted is stably made into contact with the surface of the recoding medium by means of a meniscus suction force and a damping action of lubricant applied on the surface of the recording medium.

摘要： When a negative pressure slider is used in the magnetic head support mechanism with a loading/unloading function, the gimbals is likely to be deformed or damaged. Apart from the first tab provided to the front end of the suspension, the second tab is provided to the front end of the gimbals. In addition to the Suspension supporting ramp, the ramp portion has the second ramp for supporting the gimbals. This arrangement allows the slider mounting gimbals, in addition to the suspension, to be loaded/unloaded. Unlike the conventional drive in which only the suspension is loaded/unloaded, this arrangement enables the gimbals to be loaded/unloaded while maintaining a predetermined space between the gimbals and the suspension, thus reducing the risk of gimbals deformation and damage.
