Surface defect studies of flexible media using magnetoresistive sensors

Abstract

The thermal spike frequency of magnetoreslstive sensors is investigated as a function of average head/tape flying height. A qualitative relationship between particular thermal spikes and surface defects is shown to exist and insight is gained into the nature of “flying” at submicron spacings. Results for clear and oxide coated surfaces of varying surface topography are discussed. © 1975, IEEE. All rights reserved.
