Abstract
A method and apparatus for producing dual-zone lubricated magnetic disks. An absorbent medium is held against a selected portion of the surface of a lubricated disk. The disk is rotated in relation to the absorbent medium, and the absorbent medium removes mobile lubricant from the selected portion of the disk, leaving bonded lubricant in addition to a selected amount of mobile lubricant. In an specific embodiment, an absorbent tape is supplied to a roller that holds the tape against a surface of the disk, and solvent is applied to the tape and/or disk to facilitate the removal of mobile lubricant. Differential lubricant thicknesses are thus obtained.
