ABSTRACT:
A digital output magnetoresistive ("DOMR") head for magnetic playback comprising one or more "pinned" magnetic layers having magnetic polar direction which does not rotate under an external field from the media, and a magnetic digital switching layer formed using either shape or crystalline anisotropy such that it has an easy axis parallel to the magnetic direction of the pinned layer or layers and two stable magnetization directions, parallel or antiparallel to the magnetization polar direction of the pinned layer or layers. Because of this dual stable state configuration the DOMR head produces a substantially digital output when reading magnetic information.
