Patent number: 9715889Abstract: A magnetic read apparatus has a media-facing surface (MFS) and includes a read sensor, a magnetic bias structure and an insulating layer. The read sensor has a side, a front occupying part of the MFS and a back. The read sensor includes a free layer, a pinned layer and a barrier layer between the free and pinned layers. The barrier layer has a barrier layer coefficient of thermal expansion. The magnetic bias structure is adjacent to the side of the free layer. The insulating layer includes first and second portions. The first portion of the insulating layer is between the read sensor side and the magnetic bias structure. The second portion of the insulating layer adjoins the read sensor back. The insulating layer has an insulating layer coefficient of thermal expansion that is at least ? of and not more than 5/3 of the barrier layer coefficient of thermal expansion.Type: GrantFiled: August 18, 2016Date of Patent: July 25, 2017Assignee: Western Digital (Fremont), LLCInventors: Shaoping Li, Gerardo A.
