Abstract: A suspension has an extending end and an other end. A head IC chip mounting portion is provided between the extending end and the other end of the suspension. A head slider is loaded on a first surface of the suspension at a position on the side of the extending end with respect to the head IC chip mounting portion, the head slider integrally including a head. A head IC chip is mounted at the head IC chip mounting portion of the suspension. First wiring patterns extend along the suspension between a portion of the suspension, at which portion the head slider is loaded, and the head IC chip mounting portion. Second wiring patterns extend along the suspension between the head IC chip mounting portion and the other end of the suspension. The head IC chip is mounted at the head IC chip mounting portion in a condition in which a certain portion of the head IC chip is positioned on the side of a second surface of the suspension, which second surface is opposite to the first surface.

Abstract: 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.

Abstract: A head slider, usually employed in a recording disk drive, comprises a chamfered vertex defined at a corner of a polygonal bottom surface surrounded by a contour separated from a contour of an air bearing surface. Even when the chamfered vertex collides with the surface of a recording disk, a scratch or damage may be hardly generated on the surface of the recording disk, as compared with a keen vertex. The recording disk drive employing the head slider may enjoy an improved shock resistance.

Abstract: 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.

Abstract: The head slider mounts a recording/reproducing element and flies over a recording medium with the airflow generated when the recording medium moves. The head slider comprises a slider body having an air inflow end and an air outflow end, a rail projected from the slider body to define an air bearing surface extended to the outflow end, a projection formed on the rail and between the inflow end and the outflow end, and a recess formed at the outflow end of the rail to make narrow the width of the rail. When the recording medium stops, the head slider and the recording medium are in contact at the projection and the air outflow end of the rail. Since the outflow end of the rail is narrow in width, the stiction can be prevented. Moreover, it is unnecessary to form a projection near the outflow end of the rail and thereby the flying height of the recording/reproducing element can be lowered to improve the recording/reproducing sensitivity.

Abstract: 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.

A head slider is loaded on a first surface of the suspension at a position on the side of the extending end with respect to the head IC chip mounting portion, the head slider integrally including a head. A head IC chip is mounted at the head IC chip mounting portion of the suspension.

Second wiring patterns extend along the suspension between the head IC chip mounting portion and the other end of the suspension. The head IC chip is mounted at the head IC chip mounting portion in a condition in which a certain portion of the head IC chip is positioned on the side of a second surface of the suspension, which second surface is opposite to the first surface.

Abstract: 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.

Abstract: A magnetic head slider includes a pair of rails formed on a disk opposing surface opposed to a magnetic disk, each of the rails having a flat air bearing surface for generating a flying force during rotation of the disk, a slit formed between the pair of rails at their air inlet end portions, and a groove defined between the pair of rails which is continuous to the slit and wider than the slit, for expanding the air once compressed to generate a negative pressure. The magnetic head slider further includes an electromagnetic transducer formed on an air outlet end at a position where one of the rails is located. The slider has a trapezoidal shape such that its air inlet end is narrower than its air outlet end.

Abstract: A slider body of a magnetic head slider has a leading end located upstream of an air flow generated between the slider body and a magnetic recording medium, a trailing end located downstream of the air flow, and a floating surface opposed to the magnetic recording medium. At least two rails for generating a floating force are provided on the floating surface of the slider body. A magnetic head for reading/writing data is provided at the trailing end of the slider body. A groove formed between the rails is changed in width from the leading end toward the trailing end, thereby generating an attractive force between the floating surface and the magnetic recording medium. Each of the rails has a tapering portion increased in thickness from the leading end toward the trailing end. The tapering portion terminates at a position where each rail is decreased in width from the leading end toward the trailing end.

Abstract: 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.
