Abstract:
A method and system for providing a perpendicular magnetic recording (PMR) head are disclosed. A PMR pole having a bottom and a top wider than the bottom is provided. The PMR pole may be formed by depositing a PMR pole layer, then removing part of the PMR pole layer, leaving the PMR pole. The PMR pole may also be provided by forming a trench having the desired profile in a photoresist layer, depositing the PMR pole layer, then removing the photoresist layer, leaving the PMR pole in the location of the trench. A side gap is deposited over the PMR pole. A side shield is provided on the side gap. A planarization that removes part of the side shield on the PMR pole is performed. A top gap is provided on the PMR pole, substantially covering the entire PMR pole. A top shield is provided on the top gap.
