Process for coating magnetic recording device or medium.

摘要

The present invention relates to a process for coating a magnetic recording device with a lubricating polymeric film using an ion beam source. The process comprises the steps of: (i) placing the article in a chamber; (ii) evacuating the chamber; (iii) providing a beam of ions of one sign; (iv) introducing precursor gas into the chamber; and (v) contacting the surface of the article with the beam and the precursor gas to form the polymeric film on the surface of the article.
