Patent ID: 8879208

Claim:
A trailing shield structure in a combined read head/write head; comprising: (a) a first trailing shield layer formed along an air bearing surface (ABS) and having a bottom surface that is separated from a write pole portion of a main pole layer by a write gap; (b) a second trailing shield layer (PP3) with a front side at the ABS, and a first width between two sides that are formed orthogonal to the ABS, PP3 has a first thickness in a down-track direction and contacts a top surface of the first trailing shield layer along the ABS, and extends with an arch shape to a back side that is a first length from the ABS, PP3 contacts a yoke portion of the main pole layer at a yoke length from the ABS; and (c) an umbrella shield (UmS) that is a magnetic layer formed above PP3 and substantially conforms to a shape of PP3 wherein UmS has a second width in a cross-track direction between two sides that are formed orthogonal to the ABS, the second width is greater than the first width, a second thickness in a down-track direction that is greater than the first thickness, and UmS extends for a second length from a front side to a back side such that the second length is greater than the first length.
