Thin Film Lubrication For In Contact Magnetic Recording

The arrangement effects lubrication of a magnetic recording surface to prevent wear by a contact recording head.

A pellet 1 of compressed molybdenum disulfide is spring loaded against the recording surface, such as a tape 2, immediately in front of a contact recording head 3. This results in a constant lubricating film which builds up to an equilibrium value in time.

The final thickness of the film is governed by the relative pressures on the contact recording head and molybdenum disulfide pellet, and is of the order of units of microinches in thickness. Other solid lubricants such as tungsten disulfide, graphite, or molybdenum diselinide can also be used.
