A method for fabricating a magnetic head includes forming a first pole and a flux shaping layer in spaced relation to the first pole. A nonmagnetic layer is formed adjacent the flux shaping layer and positioned on an air bearing surface (ABS) side of the flux shaping layer. A tapered recess is created in the nonmagnetic layer, the taper of the recess increasing (i.e., becoming deeper) towards the flux forming layer. The recess is filled with a magnetic material. A probe layer is formed such that it is in electrical communication with the magnetic material filling the recess.

An air bearing slider embodiment of the present invention includes a body portion having an air bearing surface (ABS) side and a flexure surface side. The ABS side has at least one air bearing surface and at least one recessed area. A thin film composed of a compressive force material is deposited within the recessed area. The compressive force material produces an omnidirectional outward force within the recessed area that creates a positive crown and camber. Preferably, the thin film has a thickness range from 10 nm to 200 nm, and is composed of diamond-like carbon (DLC). An alternative air bearing slider includes a body portion with an ABS side and a flexure surface side. A thin film composed of a tensile force material is deposited upon said flexure side. The tensile force material creates an onmidirectional inward force on the flexure side which results in positive crown and camber. The manufacturing method for the improved sliders utilizes semiconductor processing techniques. The basic slider body is appropriately masked and etched to create the air bearing surfaces, air pressure surfaces and recessed area of the ABS side. Thereafter, the compressive material thin film is deposited within the recessed area. An improved manufacturing method utilizes the preexisting photomask of a prior art slider design, such that additional photomasking steps are not required to achieve the deposition of the compressive material thin film. Manufacturing of the tensile force material embodiment requires the step of depositing the film upon the flexure side.

Air bearing slider and manufacturing method therefor

A method of lapping the air bearing surface of a magnetoresistive head which minimizes the likelihood of interelement shorts at the air bearing surface is described. In a final, linear lapping phase, the air bearing surface is lapped back and forth parallel to the longitudinal axis of the head elements in an oscillatory path across a stationary lapping surface. Any scratches or smears of the elements will be along the length of the elements rather than transverse to the elements. Any transverse scratches or smears occurring in earlier lapping phases will be removed during the linear lapping phase.
