Format patterning method for magnetic recording media

摘要

A method and apparatus for format patterning magnetic recording media with servo-control patterns is disclosed herein. The method comprises the steps of printing the control pattern using a resist in liquid form onto the media material by conventional printing techniques. A layer of a thin metallic film is then deposited over the resist and uncovered substrate areas. The resist and its overlayered metal is then removed using a liftoff technique by dissolving the resist in its particular solvent. A control pattern of deposited metallic film remains in those non-resist areas. In the alternative, the process can also use an etching bath to create the servo control pattern.
