Abstract
A system and associated methods are described for preparing a magnetic disk for installation within a disk drive system. For example, a polyfunctional lubricant may be mixed with a chemical agent to esterify the polyfunctional lubricant and cap hydroxyl groups of the polyfunctional lubricant. The magnetic disk may then be dip coated with the polyfunctional lubricant and chemical agent mixture. A polishing system then polishes the magnetic disk via an abrasive polishing tape after dip coating the magnetic disk. A portion of the chemical agent is then removed from the magnetic disk to bond a portion of the lubricant to the magnetic disk to prevent the lubricant from interfering with a read/write head when installed within a disk drive system.
