  • Recording/reproduction apparatus with an integrated inductive write, magnetoresistive read head
    Patent number: 5847907
    Abstract: In a recording/reproduction apparatus equipped with an integrated head comprising a thin film inductive write element and a MR read element and mounted on a head slider which is arranged to be rotatable about a point so as to be rotationally accessible to tracks of a disk serving as a recording medium to make yaw angles with respect to tangents of the tracks, the inductive write element and the MR read element are arranged so that a magnetic center line of the MR read element which extends in directions perpendicular to track crossing directions is separated from a geometric center line of the MR write element which extends in directions perpendicular to the track crossing directions.
    Type: Grant
    Filed: August 19, 1997
    Date of Patent: December 8, 1998
    Assignee: NEC Corporation
