摘要
A discrete-track medium and drive have been developed. The tracks are on 3.6 mu m-wide lands separated by 1.6 mu m-wide grooved guardbands on a 64mm disk. The slider was designed considering the grooves. The track-following signals are obtained through a newly developed MR head from marks embossed simultaneously with the formatting of the discrete tracks. Track eccentricity on the spindle has been overcome by introducing feed forward compensation. An areal density of 600 k bits/mm2 (similar to about 400 M bits/in2) was achieved using an external-clock driven PRML.
