Method for improving performance of thin film recording media and media obtained thereby
A data/information storage and retrieval medium, comprising:(a) a disk-shaped substrate including at least one surface with a layer stack thereon and including at least one magnetic or magneto-optical (&#8220;MO&#8221;) recording layer and an uppermost, protective overcoat layer comprising a carbon (C)-based material; and(b) a lubricant topcoat layer on the protective overcoat layer, the lubricant topcoat layer treated solely with UV radiation at a dosage sufficient to increase the glide yield, decrease the glide noise, and increase the number of CSS pass cycles of the medium before failure, relative to that of the same medium but with an untreated lubricant topcoat layer.
