Abstract
A cylindrical magnetic storage system was built and preliminary measurements were made. The system is expected to overcome the writing problems at high areal densities caused by a write head skew angle, and is aimed at the realization of 1 Tbit/in2, 2 Gbps perpendicular magnetic recording. Cylindrical substrates, sputtering equipment, and a read/write tester for a cylindrical magnetic storage were fabricated. For this preliminary investigation the length and diameter of the cylindrical substrates were 1 inch. Thin films (protective layer, storage layer, seed layer, etc.) were deposited by rotating the cylindrical substrate during the sputtering process. Fundamental read/write characteristics were measured using a merged AMR head with a pico-slider.
