Abstract

This invention is directed to methods for depositing multilayered thin films onto substrates, for example in making thin film magnetic heads. In accordance with the invention a first film, such as Cr, is deposited onto the substrate at a first pressure and a second layer, such as CoCrPt is deposited at a second pressure.
