    摘要： A magnetoresistive read sensor with improved sensitivity and stability is described. The sensor is a trilayer stack positioned between two electrodes. The trilayer stack has two free layers separated by a nonmagnetic layer and a biasing magnet positioned at the rear of the stack and separated from the air bearing surface by the stripe height distance. Current in the sensor is confined to regions close to the air bearing surface by an insulator layer to enhance reader sensitivity.

    摘要： An apparatus includes a magnetoresistive read element, first and second primary shields, and an auxiliary shield. The magnetoresistive read element is located between the first and the second primary shields, and the auxiliary shield is located between the magnetoresistive read element and the first primary shield. In another embodiment, the apparatus includes a plurality of magnets located between a plurality of shields for a magnetoresistive element. The plurality of magnets is optionally offset from the magnetoresistive element.

    摘要： A magnetic writer has at least a write pole with a first partial side shield and a second partial side shield. The write pole has a leading edge and a trailing edge along an air bearing surface (ABS) and a first side and a second side along an axis orthogonal to the ABS. The first partial side shield is separated from the first side of the write pole and extends from adjacent the write pole from the trailing edge to a location intermediate that trailing edge and the leading edge.

    摘要： A magnetic writer includes a write pole, a first partial shield and a second partial shield. The write pole has a leading edge, a trailing edge, a first side and a second side. The first partial side shield is located on the first side of the write pole, and the second partial side shield is located on the second side of the write pole. The first partial side shield and the second partial side shield extend along side of the write pole from the trailing edge to a location intermediate that trailing edge and the leading edge so that the first partial side shield and the second partial side shield do not shield the leading edge.
