Abstract: In a magnetic disk file having a plurality of disks and a source of organic lubricant mounted within a housing, an air flow stream recirculates within the housing. The vapor pressure of the lubricant source is controlled to provide vapor phase transport of lubricant molecules between the source and the disks' recording surfaces. The lubricant molecules bidirectionally transfer between the air stream and the source, and between the air stream and the surface of the disks, as is needed to maintian a nomo-molecular lubricant film, in the range of about 3 to 15 angstroms, on the disks in accordance with the principle of Langmuir kinetics. The disks are rigid disks and their recording surface includes a carbon overcoat. This overcoat has an affinity for the airborne organic lubricant molecules. In a first embodiment, the vapor pressure of the lubricant is controlled by mounting the material at the coolest location within the housing. In a second embodiment, the lubricant is carried as a mono-molecular layer of lubricant on granular carbon particles which have a surface area that is many times greater than the surface area of the disks. In a third embodiment, the vapor pressure is controlled by combining the lubricant with a vapor pressure diluent.

Abstract: A process for producing a reactive ion-etched structure with height and width dimensions of the order of 25 microns or less on a ferrite substrate (12) surface is disclosed. A mask (18) of positive water saturated photoresist is formed on the substrate. A metal taken from the group consisting of nickel and a nickel-iron alloy is plated through the mask. The photoresist mask is removed to leave a pattern (20) in the plated metal. The ferrite substrate surface that is exposed by the pattern is reactive ion etched with a power density of more than 1w/cm 2 and a bias voltage less than -100 volts.
