【Abstract】 The offtrack and crosstalk properties of perpendicular recording with a single pole head are investigated. Comparison with the offtrack properties of the longitudinal ring head shows that the crosstalk from the neighbouring track using perpendicular recording with a single pole head is smaller than that using a longitudinal ring head. The single pole head is advantageous to the reduction of the width of magnetic disk. A new method of azimuth recording is proposed to improve areal recording density and to realize high track density magnetic recording at the same time because of the narrow actual recorded track width and the elimination of the guardband. Dual-track azimuth heads have been developed. The track density for the floppy disk driver with such a head can be increased by twofold as compared with the conventional head of the same track width.更多还原
