The present invention relates to a novel monolithic read/write recording head for use in disk drives. The airborne slider body and the transducer nose portion of the head is made from the same magnetic ferrite material. The magnetic material preferably consists of NiZn ferrite or MnZn ferrite. A narrow track surface has a non-magnetic gap interposed across the track at some distance atop the I-bar coil assembly, between the slider and the transducer portion. For protection, this gap and track ar...

A magnetic head slider suspension assembly for loading a head slider having air bearing surface onto the surface of a magnetic rotating disc is shown. The magnetic head slider suspension assembly includes an elongated slider arm adapted to be attached to an arm mounting support. The elongated slider arm includes a deflectable central arm section or load beam having a support end at one end thereof operatively attached to the arm mounting support and a head/slider loading end located at the other...

A magnetic head has a slider provided with reading/writing elements wherein the slider has a recessed portion for generating a negative pressure at a surface so that the bottom surface of the recessed portion is slanted at a predetermined grade toward the surface at the side of an air in-flowing end, and the bottom surface terminates at an end of the slider at the side of an air discharging end.

Salient embodiments comprise a magnetic recording slider whose record-confronting face is characterized by two or three rails wherein stiction forces are counteracted by provision of piezo-electric boss means on one or several rails, or therebetween.

A slider having a pair of rails with elongated surfaces which face the disk and are oriented generally along the direction of motion of the disk; a cavity, inset relative to the rail surfaces, is configured to produce subambient pressure tending to draw the slider toward the disk; at least one of the rail surfaces is interrupted by at least one detail configured to reduce the variation in roll for different yaw angles. In another aspect, a slider has at least one groove cut in at least one rail;...

An air bearing slider for supporting an electromagnetic transducer over a rotating disk. The slider comprises a slider body having a leading edge, a trailing edge and first and second side edges. First and second side rails are positioned along the first and second side edges, respectively, and form air bearing surfaces with inside and outside edges. The inside and outside edges converge from the leading edge to a break and diverge from the break to the trailing edge.

A magnetic head slider of the present invention includes a generally C-shaped leading rail extending from the leading edge of an air bearing surface and concave toward the trailing edge of the same. A pair of trailing rails extend from substantially the center of the concavity of "C" of the leading rail and flared away from each other toward the trailing edge. The trailing rails are spaced by a preselected distance from each other in the vicinity of the concavity of the trailing rail, then exten...

A slider for developing an air bearing atop a spinning data disk includes a substrate having a base surface and an air bearing pad extending outwardly therefrom. The bearing pad cooperates with the spinning disk to develop the air bearing thereon for supporting the slider thereabove. A data access element is fixedly mounted in the substrate for communicating data with the disk and, a guard strip extends outwardly from the base surface and is spaced from the bearing pad to define a trench therebe...

An air-bearing head slider for supporting an electromagnetic transducer opposite to a rotating recording media or magnetic disk. A slider body has a surface having a leading or air-entry side and a trailing or air-delivery side. Two rails are provided on the surface of the slider body and has floating surfaces opposite to the rotating magnetic disk for generating a floating force. The two side rails extend along a direction of air flow generated by the rotation of the magnetic disk and define a ...

The present invention is directed to provide a magnetic head that is capable of effectively preventing TA noise. A slider 1 is provided with air bearing surfaces 111 and 121. Electromagnetic conversion elements 2 and 3, which are provided toward the trailing edge TR of the slider 1, perform electromagnetic conversion at the air bearing surfaces 111 and 121. The slider 1 is provided with indented portions 114 and projecting portions 115 at the air bearing surfaces 111 and 121 where the electromag...
