Patent ID: 8749920

Claim:
A magnetic recording device comprising: a slider comprising an air bearing surface (ABS), a leading side, and a trailing side; a head residing on the slider, the head comprising: a first magnetic transducer; a first heater for heating an area proximal to the first magnetic transducer; a first shield (S1) comprising a first material on the leading side of the first magnetic transducer; a second shield (S2) comprising the first material on the trailing side of the first magnetic transducer; a first pole (P1) comprising the first material on the trailing side of the second shield (S2), wherein the first pole (P1) is between 0.6 micron and 2.0 micron thick, and the second shield (S2) is less than 0.6 micron thick; a third shield (S3) on the trailing side of the first pole (P1); and a proximity sensor for sensing proximity to a recording media in an area proximal to the first pole (P1), wherein the proximity sensor is between the first pole (P1) and the third shield (S3).
