The magnetic transducer includes a perpendicular magnetic recording (PMR) pole, an additional pole, a stitch, a shield, a write gap between the PMR pole and a portion of the shield, and at least one coil that energizes at least the additional pole. The PMR pole has a first front portion proximate to the ABS, while the additional pole is recessed from the ABS. The stitch resides between the PMR pole and the additional pole and has a stitch front portion between the front portion of the PMR pole and the additional pole. At least a portion of the write gap resides on the front portion of the PMR pole. At least a portion of the additional pole resides between the PMR pole and the shield."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"PMR head with an angled stitch layer","description":"A method and system for providing a magnetic transducer having an air-bearing surface (ABS) are described.
