ABSTRACT:
A process for forming magnetic targets for position and speed sensors, and magnetic targets formed according to the process. The targets are formed on a conductor-clad substrate by first applying a layer of photoresist material and then patterning and etching the photoresist to form trenches defining the shape and dimensions of the targets. Magnetic material is formed in the trenches and magnetized to form the targets.
