摘要： A slider portion is provided with protrusion portions having a spherical surface, contacting a recording medium. A center of a magnetic pole is arranged on the line C1 connecting the vertices of the protrusion portions. Line C1 is more or less aligned with the gliding direction of the protrusion portions. Thereby, positional variations between the magnetic pole and the surface of the recording medium can be minimized even when the head slider is tilted with respect to the surface of the recording medium. Thus, a gliding converter support structure is provided whose conversion efficiency does not decrease when it is tilted with respect to the surface of the recording medium, which is easy to manufacture, has little gliding resistance, and does not easily accumulate dust.

摘要： An improved magnetic head comprises a slider and a thin film element, the later of which is provided on a trailing side of the slider. The slider has core layers. The surfaces of the core layers are abraded so that the thickness of an a phase constituting the surface structures of the core layers may be reduced to a very small value. In this way, even if a carbon film is directly formed on the core layers, it is still possible to ensure a desired diffusion between the carbon film and the a phase, thereby effectively preventing the carbon film from separation (peeling) and avoiding the formation of any spot on the carbon film.

摘要： A slider is used in an optical or magneto-optical head having an optical assembly mounted on the slider body, for directing a read-write laser beam onto and from a data storage disk. The optical assembly includes an optical fiber a mirror a quarter wavelength plate, and a lens. The optical fiber guides the laser beam along an optical path defined by the optical assembly and the slider body. The laser beam emanating from the optical fiber impinges upon the mirror and is reflected thereby onto and through the quarter wavelength plate. The laser beam continues its travel along the optical path through the lens and a magnetic coil assembly onto the disk. The slider includes a channel pattern formed on its upper surface for positioning the optical components on the slider body. The channel pattern includes a plurality of channels that define an optical path, and a plurality of cavities formed along these channels for receiving various components such as optical, magnetic and electrical components.

摘要： A disk drive system includes a base, a disk stack rotatably attached to the base, and an actuator assembly movably attached to the base. A ramp assembly includes a set of ramps for loading and unloading the sliders and transducing elements carried by the sliders to and from the disks in the disk stack. The ramp assembly is attached to the base. An actuator assembly is movably attached to the base of the disk drive. The actuator assembly moves the load springs and attached slider and transducers to various positions on the disk. The slider is a block of material having corners and edges. Sliders have a backside surface and an air-bearing surface. The slider also has at least one recess therein. One or more pads of shock absorbing material are positioned within at least one of the recesses in the slider. The pads are positioned within one or more recesses to prevent the corners or edges of the block of material near the air-bearing surface from contacting the disk. In one embodiment, the pads are positioned within the recesses so that the second material is positioned near the air-bearing surface. The pads include a first shock absorbing material, and a second material harder than the shock absorbing material. The second material can be diamond like carbon. After forming the pad, diamond like carbon is deposited on the pad using photolithography.
