    摘要: A method for merging sensor field-mill and electronic lapping guide material placement for a partial mill process and sensor formed according to the method is disclosed. An electronic lapping guide is formed coplanar with a sensor. The coplanar electronic lapping guide and sensor are processed to provide the electronic lapping guide and sensor with predetermined dimensions. The merging of the sensor field-mill and placement of the electronic lapping guide material for partial mill CPP eliminates steps and therefore the cycle time. Moreover, the electronic lapping guide region is raised to the height of the sensor plane to allow the sensor and electronic lapping guide to be defined in the same focal plane of the optics.

    摘要: A slider for a magnetic disk drive is disclosed which includes a heater circuit structure, and at least one ELG circuit structure where a portion of the ELG circuit structure is removable by lapping. The ELG circuit structure is connected electrically in parallel with the heater circuit structure to a common set of electrical contact pads to produce a measured initial parallel resistance as measured at the common set of electrical contact pads. A modified parallel resistance is calculated to correspond to that of the modified individual resistance of the ELG when lapping operation is completed. The resistance is monitored during lapping operations to signal when the appropriate lapping depth is achieved. Also disclosed is a disk drive having the slider, and a method of fabrication for a slider.

    摘要: A recording head is disclosed that includes electrical pads on multiple surfaces. The recording head includes a substrate portion abutting a deposited portion. The deposited portion includes an air bearing surface (ABS) (or bottom surface), an end surface, and at least one other surface. The end surface is the surface traditionally used by head designers for electrical pads. In accord with the invention, one or more electrical pads are included on the other surfaces of the deposited portion (i.e., a surface other than the end surface). Electrical pads may also be included on the end surface.

    摘要: Tunneling magnetoresistive (TMR) electrical lapping guides (ELG) are disclosed for use in wafer fabrication of magnetic sensing devices, such as magnetic recording heads using TMR read elements. A TMR ELG includes a TMR stack comprising a first conductive layer, a barrier layer, and a second conductive layer of TMR material. The TMR ELG also includes a first lead and a second lead that connect to conductive pads used for applying a sense current to the TMR ELG in a current in plane (CIP) fashion. The first lead contacts one side of the TMR stack so that the first lead contacts both the first conductive layer and the second conductive layer of the TMR stack. The second lead contacts the other side of the TMR stack so that the second lead contacts both the first conductive layer and the second conductive layer of the TMR stack.

    摘要: In a tunnel magnetoresistive (TMR) device, free sublayers are separated by an intermediate spacer layer that serves to ensure a uniform circumferential magnetization in the free stack, counterbalancing orange-peel coupling by antiferromagnetic exchange coupling. Thus, a CPP MR device may have a seed stack, a pinned stack on the seed stack, and a tunnel barrier on the pinned stack. A free stack can be on the tunnel barrier, and the free stack can include structure for promoting uniform circumferential magnetization in the free stack.
