Abstract:
A perpendicular magnetic recording (PMR) transducer is provided. The PRM transducer includes a PMR pole having a top, a bottom, and at least one sidewall, the bottom having a bottom width, the top having a top width bigger than the bottom width. The PRM transducer further includes an intermediate layer adjacent to the at least one sidewall, a write gap on the PMR pole, the write gap including a first layer on the PMR pole, the first layer including a planarization stop layer, and a shield on the write gap.
