Shield designed for middle shields in a multiple sensor array

摘要

A method and system provide a magnetic transducer having an air-bearing surface (ABS). The method provides a first read sensor stack and defines a first read sensor in a stripe height direction from the first read sensor stack. The stripe height direction is perpendicular to the ABS. A shield is provided on the first read sensor stack and in a down track direction from the first read sensor stack. A second read sensor stack is provided. The shield is between the first read sensor and the second read sensor stack in the down track direction. Both the first read sensor and the second read sensor are defined from the first read sensor stack and from the second read sensor stack, respectively, in a cross-track direction. The cross-track direction is substantially perpendicular to the down track direction and substantially perpendicular to the stripe height direction.

1. A method for providing a magnetic recording device, the method comprising:
providing a media including a plurality of tracks having a track pitch; and providing a magnetic read transducer having an air bearing surface (ABS), the step of providing the magnetic read transducer including:
providing a first read sensor stack;defining a first read sensor in a stripe height direction from the first read sensor stack, the stripe height direction being perpendicular to the ABS;providing a shield on the first read sensor stack and residing in a down track direction from the first read sensor stack;providing a second read sensor stack, the shield residing between the first read sensor and the second read sensor stack in the down track direction; anddefining both the first read sensor from the first read sensor stack and a second read sensor from the second read sensor stack in a cross-track direction, the cross-track direction being substantially perpendicular to the down track direction and substantially perpendicular to the stripe height direction, the first sensor and the second sensor configured to read a portion of the plurality of tracks at a skew angle of greater than zero degrees; wherein a distance between the first read sensor and the second read sensor in the down track direction is configured such that the track pitch divided by the distance is substantially equal to the cosine of the skew angle.
