Abstract:
The present application relates to a write gap structure for a magnetic recording head. In illustrated embodiments, the write gap structure includes multiple write gap segments along a beveled pole tip surface between a top edge and a bottom edge of the beveled pole tip surface to provide a narrow write gap proximate to the air bearing surface and a larger write gap behind the air bearing surface. In illustrated embodiments, the narrow write gap segment is formed between the beveled pole tip surface and a lower back surface of front shield and the larger write gap is formed between the beveled pole tip surface and an upper back surface of the front shield.
