Abstract

Results of quasi-contact recording on rigid perpendicular disks are presented in this paper. Footprints of Various recording heads on different recording media, obtained at quasi-static contact conditions using a high resolution magnetoresistive transducer provide useful information such as sharpness of the magnetization transition and the effect of the demagnetizing field. Very high density magnetization transitions, up to 12500 fc/mm, on single-layer perpendicular rigid disks were recorded and read back by thin film ring heads at a velocity of 5-8 m/s under quasi-contact conditions. At high linear densities the amplitudes on the experimental density response curve are higher than those obtained by the linear superposition of experimental isolated pulses. © 1985, IEEE.
