Abstract

The potential of perpendicular recording system for realizing 52.5 Gb/in² was clarified. To realize a recording density of over 50Gb/in², a quarter-micron-track-width perpendicular head consisting of an SPT writer and an advanced GMR reader was developed. A low-noise and thermally stable double-layered medium and a signal processing technique suitable for perpendicular recording channel were also developed. At the same time, high frequency write characteristics at around 60MB/s as well as the acceptable thermal stability characteristics were also confirmed at a room temperature.
