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.
Claims37
A disk drive comprising:
- a) a magnetic recording disk;
- b) a magnetoresistive or magnetic tunnel junction and inductive write head supported on a slider for magnetically reading data to or magnetically writing data from the magnetic recording disk;
- c) an actuator connected to the slider for moving the magnetoresistive or magnetic tunnel junction and inductive write head across the magnetic recording disk;
- d) a mechanism for moving the magnetic recording disk relative to the magnetoresistive or magnetic tunnel junction and inductive write head;
- and
- e) a corrosion inhibitor package comprising at least one vapor phase corrosion inhibitor embedded in a polymeric matrix.
