A method and system for forming a microscopic transducer are described.
The method and system include forming a plurality of adjoining sensor
layers. The sensor layers include a first magnetically soft layer, a
nonmagnetic layer on the first magnetically soft layer, and a second
magnetically soft layer on the nonmagnetic layer. The method and system
also include forming a sidewall over the second magnetically soft layer.
The sidewall formation includes forming a base having a surface oriented
substantially perpendicular to the sensor layers and depositing an
electrically conductive material on the surface. The method and system
also include removing a portion of the sensor layers not covered by the
sidewall.
