Title:
MAGNETORESISTIVE EFFECT TYPE HEAD
Document Type and Number:
Japanese Patent JP2543654
Kind Code:
B2
Abstract:
PURPOSE: To obtain a narrow gap head for high density recording having high reproduction sensitivity by disposing a yoke while exposing to the opposing face of a recording medium in a gap provided for a magnetic pole and using the yoke as a flux guide for transmitting the magnetic field of the medium to a magnetoresistive effect layer.
CONSTITUTION: The magnetoresistive effect type head comprises patterns of a thin film magnetic pole 1, a conductor coil 2, a dielectric layer 3, etc., formed substantially in parallel with the opposing face of a magnetic recording meadium, wherein the magnetic pole 1 is provided with a magnetic ring circuit 4 surrounding the conductor coil 2. The horizontal magnetoresistive effect head 10 is also provided with a nonmagnetic gap 5 substantially normal to or oblique to the opposing face of the medium. The magnetoresistive effect type head further comprises a magnetoresistive effect layer 6 disposed in the magnetic ring circuit 4 and not exposed to the opposing face of the medium, and a yoke 7 functioning as a flux guide for inducing magnetic field of the medium in the layer 6 while having one end coupled magnetically with the layer 6 and the other end coupled magnetically with the gap 5.
