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 a by write head skew angle and is aimed at the realization of 1-Tb/in2 2-Gb/s 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 in. 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 an 8-mm video-tape-recorder metal-in-gap head and a merged giant magnetoresistive head with a pico-slider.
