摘要： The present invention is aimed to provide a head suspension having a high resonant frequency, high shock resistance and low rigidity, which greatly contributes to an improvement of a magnetic disk apparatus. In an oscillation-type actuator, at least a part of a spring arm of the head suspension having a data reading/writing head slider 1 is made of an anisotropic layer whose rigidity varies in accordance with a direction. In this case, the anisotropic layer is laminated so that the high rigidity modulus orientation direction is different according to layer.

摘要： A rail is formed on a medium-opposed surface of a slider body in a flying head slider. An air bearing surface is defined on the upper surface of the rail, which faces the medium. Projections are formed on the medium-opposed surface. The projections serve to space the air bearing surface from a medium such as a recording disk when the slider body contacts the recording disk. A trailing end of the rail is narrowed laterally along the trailing end of the medium-opposed surface. Even when the slider body contacts the recording disk at the trailing end, in addition to the projections, the contact area between the slider body and the recording disk is reduced because of the narrowed trailing end. Since the rail is narrowed without changing its original thickness or height from the bottom base of the medium-opposed surface, no additional processing is required to form the air bearing surface.

摘要： An air-bearing head slider supports an electromagnetic transducer opposed to a rotating recording medium or magnetic disk. The slider includes a slider body having a bottom surface opposed to the rotating magnetic disk, the bottom surface having an air-entry end and an air-delivery end with respect to an air flow generated between the slider body and the rotating recording medium. A central rail is provided on the surface of the slider body at the air-entry end. The central rail extends from the air-entry end and terminates on its way to the air-delivery end. Two side rails are provided on the surface of the slider body at the air-delivery side and extend from the air-delivery end and terminate on their way to the air-entry end. An air flow passage, extending from the air-entry end to the air-delivery end, includes air gaps defined between the central rail and the two side rails and an area on the bottom surface located downstream of the gaps, so that a negative pressure is generated in the downstream area due to the air flow passing through the gaps.

摘要： A flying head slider includes a slider body. The upstream or leading end of a bottom surface on the slider body is defined along a first datum line extending in the lateral direction of the slider body. The first datum line may be set perpendicular to the longitudinal centerline of the slider body. The upstream or leading end of the front air bearing surface is defined along a second datum line intersecting the first datum line at a predetermined inclined angle. As the incidence angle of an airflow colliding against a step defined at the leading end of the front air bearing surface gets decreased, the pitch angle of the slider body also gets decreased in the flying head slider during flight.

摘要： A magnetic head assembly equipped with a slider and a gimbal spring to which the slider is secured with an adhesive agent. According to one aspect, at least one slit is formed in the gimbal spring opposing the adhesion surface of the slider, so that expansion and contraction of the gimbal spring caused by a change in the temperature is hardly transferred to the slider. According to a second aspect, the Young's modulus after hardening of the adhesive agent applied onto thee adhesion surface of the slider is selected to be smaller than about {fraction (1/13000)} of the Young's modulus of the slider material or of the gimbal spring material. According to the first aspect, therefore, the area of the gimbal spring on which the adhesive agent is applied is limited by the slit. According to the second aspect, the Young's modulus of the adhesive agent after hardening is so small that the warping amount of the slider caused by a change in the temperature lies within a predetermined range. The warping amount of the slider in the magnetic head assembly is hence suppressed to lie within an allowable range despite a change in the temperature, and floating performance of thee slider is stabilized.

摘要： A negative pressure air bearing slider including a first air bearing surface formed on the bottom of the slider body at the upstream position so as to extend in the lateral direction of the slider body, and a pair of second air bearing surfaces formed on the bottom of the slider body separately from the first air bearing surface at downstream positions spaced in the lateral direction so as to define an air stream passage therebetween. The second air bearing surfaces serve to generate positive pressures that are spaced apart at downstream positions where a transducer element is embedded in the slider body, so that the slider's stiffness to rolling action can be enhanced. The cooperation of the front and rear rails enables for the creation of a higher negative pressure.

摘要： A magnetic head slider has a plurality of rail planes to generate a floating force by using an air flow passing through a region between a group of the rail planes and a magnetic disk rotated at a constant rotating speed, and the slider floats up into the air according to the floating force. Also, the slider has a first pad arranged near an air inflow end of one rail plane and a second pad arranged near an air outflow end of the same or another rail plane, and a height of the first pad and a height of the second pad respectively range from 20 to 50 nm. Therefore, a coefficient of a friction between the pads and the magnetic disk can be reduced, and the wear of the pads can be prevented. Also, the contact of an electro-magnetic transducing device attached to the air outflow end of the rail plane with the magnetic disk can be prevented.

摘要： A pair of slits are defined in a slider body of a head slider so as to extend from a trailing end surface to the leading end on the slider body. A movable block is established in the slider body between the slits. The slits ensure the extent of movement for the movable block. Elongated plates enable a relative displacement between the movable block and a stationary block. A head element is mounted on a trailing end surface of the movable block. The thickness of a non-magnetic layer corresponds to the gap length of the head element. The gap length of the head element can easily be controlled based on deposition of the non-magnetic layer. The thickness of the non-magnetic layer can be reduced in a relatively facilitated manner, so that the gap length of the head element can easily be minimized.
