Abstract
The magnetic surfaces of the magnetoresistive or magnetic tunnel junction and inductive write head and magnetic recording disk of a hard disk drive are protected from corrosion by inserting a vapor phase corrosion inhibitor (VPCI) package into the disk drive for providing additives in the vapor phase of the disk drive enclosure to maintain an equilibrium and renewable adsorbed film of metal passivators on the head and disk surfaces. The VPCI package includes at least one vapor phase corrosion inhibitor (VPCI) embedded in a polymeric matrix.
