Integrated thin film magnetic head with planar structure

摘要

Thin film magnetic head structure includes digital read/write heads and analog read heads integrated on a single substrate. The "wrap around pole effect" is reduced or eliminated by having the thicknesses of the digital lower flux guides and the analog read gap-defining layer approximately the same, resulting in improved signal output from the digital read heads. The structure is useful in cassette decks designed to play both digital and analog compact cassettes.
