A Low Inductance Metal-in-gap Head Using A Side-core Concept

Abstract

IntroductionThe demand for higher recording density and faster data transfer rate of magnetic storage devices continuouslv reauires the develomnent of new type of head technologies. Meta-ingap(M1G) heads were ir;troduced[l] to Gable a magnet:; recording head to write information on a high coercive media increasing the bit density on a track, and single crystal MIG technologies were later introduced[2] to improve the amplitude and SIN ratio of MIG heads.
