1. A method for maintaining a mono-molecular layer of an organic lubricant on a recording surface, comprising:

  • providing a magnetic recording surface having an affinity for organic lubricant molecules,coating said recording surface with a mono-molecular layer of an organic lubricant,mounting said recording surface in container that is at least partially closed,inducing an airflow stream within said container,mounting a supply of an organic lubricant within said container and in said air stream at a location that is spaced from said recording surface, andcontrolling the vapor pressure of said lubricant supply so as to establish a condition whereby said air stream (1) picks up lubricant molecules, (2) receives lubricant molecules, or (3) neither picks up nor receives lubricant molecules, from said lubricant supply and/or said recording surface, as is required to maintain said mono-molecular lubricant layer on said recording surface.
