    摘要: A process is described for fabricating sliders with reduced lapping damage to the hard-bias materials. The stack of layers for the magnetic sensor is deposited on a wafer and patterned into an initial shape. The hard-bias structures are fabricated at the side of the magnetic sensor as in the prior art. In each of the two described embodiments of the invention, the hard-bias material below the ABS is reduced or removed and replaced with a fill material such as alumina. A first embodiment reduces the hard-bias material below the ABS by forming an extended lapping gap along the ABS in both the sensor and hard-bias material. A second embodiment forms a photoresist mask over the sensor and the portion of the hard-bias/lead structures above the ABS and the exposed hard-bias/lead material below the ABS is thinned or completely removed by milling.

    摘要: Magnetic data storage devices use read/write heads to transfer data between the magnetic storage medium and the rest of the system. The read head is constructed with a magnetic layer called a free layer whose magnetic axis rotates based upon external magnetic influences of the magnetic storage medium. The free layer is biased into a predetermined magnetic orientation with the magnetic influence of a layer called a hard bias layer. Orientation of magnetic axes within the hard bias layer is desired. This document describes a hard bias layer whose magnetization exhibits uniaxial magnetic anisotropy.

    摘要: A slider is described with a resistive electro-lapping guide (ELG), which is aligned with a structure in the write head such as the throat height or trailing shield thickness and extends from the lapping region through the ABS and is connected to pads on the surface of the slider. In a second embodiment the ELG is disposed entirely in the section of the slider which will be removed by lapping. Another embodiment of the invention is a system for single slider lapping which simultaneously monitors the resistance of the read sensor or a read head ELG and at least one ELG that is aligned with a structure in the write head. A controller uses the resistance information to implement an algorithm which decides when lapping should be terminated.
