Abstract

A carboxylic acid terminated lubricant is chemically bonded to the surface of particulate magnetic media by applying an oxygen plasma to the surface followed by intimate contact with the lubricant. The durability and stiction of the particulate magnetic media is substantially increased.

Process for Chemically Bonding Lubricant to Particulate Magnetic
Media Surface

      A carboxylic acid terminated lubricant is chemically bonded to
the surface of particulate magnetic media by applying an oxygen
plasma to the surface followed by intimate contact with the
lubricant.  The durability and stiction of the particulate magnetic
media is substantially increased.

      A carboxylic acid terminated is chemically bonded to a
particulate magnetic media surface by contacting the surface with the
lubricant.  The amount of irreversibly bonded lubricant is controlled
by oxygen plasma treatment of the surface, prior to lubricant
application.  The lubricant is applied by spin-on, wipe-on, or spray
methods to the disk surface as a pure liquid lubricant or as a dilute
solution of the lubricant in a suitable solvent.

      In another variation of the process, an additional layer of
lubricant can be added on top of the chemically bonded lubricant.
The chemically bonded lubricant systems show enhanced mechanical
performance.
