  • Method and system for providing a write head having a conforming pole structure
    Patent number: 6204999
    Abstract: A system and method for providing a write head is disclosed. The write head includes a first pole and a write gap. At least a portion of the write gap is on a portion of the first pole. The method and system include providing a coil layer including a plurality of turns on the write gap. Each of the plurality of turns is separated by a pitch. The method and system further include depositing an insulator to provide an insulating layer and providing a second pole above the insulating layer. The insulating layer has a first profile substantially conforming to the plurality of turns.

  • System for biasing a synthetic free layer in a magnetoresistance sensor
    Patent number: 6201673
    Abstract: A system and method for providing a magnetoresistive head is disclosed. The method and system include providing a spin valve including a synthetic free layer. The synthetic free layer includes a ferromagnetic layer. The method and system also include providing an antiferromagnetic biasing layer exchange coupled to a first portion of the ferromagnetic layer. The antiferromagnetic biasing layer magnetically biases the synthetic free layer to ensure the single domain structure and reduce noise.
