阐明了垂直记录系统实现52.5Gb/in 2的潜力。为了实现超过50 Gb/in 2的记录密度，开发了由SPT写入器和先进的GMR读取器组成的四分之一微米磁道宽度的垂直磁头。研制了一种低噪声、热稳定的双层记录介质和适合于垂直记录通道的信号处理技术。同时，在室温下也确认了约60 MB/s的高频写入特性以及可接受的热稳定性特性。
The potential of perpendicular recording system for realizing 52.5Gb/in2was 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.
