Improved recording performance using side-shielded pole head in PMR drive

Abstract

A recording performance for the side shielded pole head (SSPH) with trapezoidal pole tip is compared to a conventional single pole head (CSPH) with the SiO/sub 2/ dispersed double-layered perpendicular magnetic recording (PMR) media. The SSPH showed 3 dB higher SNR, 22.5% enhanced D/sub 50/, and about 10 dB better NLTS compared to the CSPH design. Noise… (More)
