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.

摘要： A magnetic disk device having a head integrated circuit mounted on a magnetic head supporting mechanism. In order to secure the reliability by controlling the integrated circuit temperature below a predetermined level, the difference in the integrated circuit cooling ability which varies with the radial position on the disk is quantified, so that power (signal) sufficient to maintain a constant temperature according to the integrated circuit temperature is supplied to the integrated circuit. Since the cooling ability at a given radial position of the integrated circuit is not exceeded by the power consumption, the integrated circuit temperature can be maintained below a predetermined level.

The air bearing surface includes a pair of side rails extending on both sides of the air bearing surface from the front end in the longitudinal direction of the slider, a center rail provided at the center of the air bearing surface in the transverse direction and extending from the front end to the rear end in the longitudinal direction of the slider, a cross rail extending in the transverse direction of the slider to connect the pair of side rails and the center rail to each other near the front end, a pair of recesses defined by the pair of side rails, the center rail and the cross rail, communicating grooves for communicating the pair of recesses with the front end, and a head mounted on a rear end surface of the center rail. The pair of side rails, the center rail and the cross rail lie substantially in the same plane. The pair of side rails are spaced from the rear end and are terminated at oblique edges in agreement with oblique lines extending from side edges of the slider to the center of the center rail at its rear end. The pair of side rails each has a width shape which is gradually narrowed from the front end toward a narrow portion located in a vicinity of a center of the slider, and is gradually spread from the narrow portion toward the rear end. The center rail is extended from the front end with substantially a constant width, followed by a width shape gradually spreading toward the rear end.

摘要： A magnetic disk device and a flying slider, having a magnetic head for reading and writing information, are disclosed. The magnetic head slider includes flying pads of a stepped configuration for flying the slider, and each of the flying pads has a flat surface portion and a step surface recessed from this flat surface portion through a microscopic step. Microscopic projections are formed on the step surface. The height of the microscopic projections are higher than or substantially equal to the height of the step. With this construction, the slider is less liable to be turned to lean forward because of the provision of the microscopic projections, and beside a front edge of the step surface will not damage a magnetic disk surface. A variation of the flying height can be reduced by a negative pressure produced at the rear side of each microscopic projection. Therefore, there can be provided the magnetic disk device having high reliability and a large capacity.

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.
