Abstract:
A magnetic reproducing head, comprising:a magnetoresistive effect element disposed crossing at least two recorded tracks on a magnetic recording medium, said recorded tracks being subjected to concurrent reproduction process, said magnetoresistive effect element allowing a flow of an internal current in a direction which depends on a sense current fed thereto, and having an easy axis of magnetization longitudinally oriented;detecting electrodes of which the number is equal to the number of reproduced recorded tracks +1, said detecting electrodes being bonded on one of the large surfaces of said magnetoresistive effect element while vertically disposed between said recorded tracks; anddomain control layers of which the number is equal to that of said detecting electrodes, said domain control layers being closely formed between said magnetoresistive effect element and said detecting electrodes,wherein said magnetoresistive effect element has an element width at least three times as large as an element height and each of said domain control layers has a width shorter than the width of a portion having no information recorded therein and being located between said recorded tracks, said domain control layers capable of generating a unidirectional magnetic field directed in an orientation of an initial magnetization in a single magnetoresistive effect element, the orientation of which depends on a direction of an easy axis for said magnetoresistive effect element.
