The IP.com Prior Art Database
The structure disclosed uses thin magnetic shields abutting the sensor stack to provide high track resolution. The shields are insulated from the sensor by an insulating material, e.g., a thin layer (50 A) of Al2O3. The shield surface is planarized by chemical/Mechanical poishing and then regular shield is put on top of these side shields and the sensor stack.
