ABSTRACT:
A method of manufacturing an active element for use with a magnetic head includes depositing a magnetic material to form a magnetic member, and nitriding the magnetic member after the depositing step. Preferably, the depositing step comprises depositing nickel-iron alloy, and the nitriding step comprises plasma nitriding the magnetic member. Advantageously, plasma nitriding may be performed at a temperature below 300 degrees Celsius to avoid adverse effects to components of the active element, such as organic planars. Active elements manufactured according to the method of the invention are also disclosed.
