摘要： In one aspect described herein, a read head having one or more magnetoresistive (MR) sensors (or devices) is provided. In one example, the read head includes an MR sensor (324) and an insulator layer (326) disposed at the same level as the MR sensor. The read head further includes a bearing surface, wherein the insulator layer (326) forms a portion of the bearing surface and is disposed between a surface of the MR sensor (324) and the bearing surface to provide protection for the MR sensor from exposure to the bearing surface. The MR sensor (324) may include a stack of thin-film layers to form an AMR, GMR, or TGMR sensor element. The stack may further include a slanted surface portion, wherein the insulator layer (326) is disposed on the slanted surface portion, thereby recessing the MR sensor (324) from the bearing surface.

摘要： According to one aspect, an exemplary method for manufacturing a magnetic head includes forming a plurality of magnetoresistive devices, a reference device, and a monitoring device, where the reference device includes a desired stripe height less than the magnetoresistive devices and monitoring device. Material is removed from the air/tape bearing surface, e.g., by lapping, thereby reducing the stripe height of the magnetoresistive devices and monitoring device. A characteristic of the reference device, e.g., resistance, voltage, or the like, is compared with a similar characteristic of the monitoring device, wherein the characteristic of the monitoring device varies as material is removed. Material may be removed from the bearing surface until the characteristic of the monitoring device and the reference device are substantially equal, at which time, the stripe height of the monitoring device and magnetoresistive devices are substantially equal to that of the reference device.
