  • Inhibiting oxidation of organic contaminants in a hard disk drive (HDD)
    Patent number: 8405929
    Abstract: An information storage system including an enclosure, a rotating data storage medium including a surface, a slider including an ABS and an airborne oxidizable contaminant disposed in the enclosure. The system also includes an antioxidant absorbed onto the surface of the data storage medium. The antioxidant inhibits oxidation of the oxidizable contaminants at an interface between the ABS and the rotating data storage medium.
    Type: Grant
    Filed: December 29, 2009
    Date of Patent: March 26, 2013
    Assignee: HGST Netherlands B.V.
    Inventors: Sahba Ghaderi, John Martin Burns, Charles Hignite, Vedantham Raman, Thomas Karis, Charles A. Brown

  • Disk drive system with hydrodynamic bearing lubricant having charge-control additive comprising dioctyldiphenylamine and/or oligomer thereof
    Patent number: 7212376
    Abstract: An improved disk drive system that employs a lubricant with improved charge control is provided. The disk drive system is comprised of a rotatably mounted magnetic disk. A rotor is coupled to the disk and rotatably retained by a stator. A bearing is formed that serves as an interface between the stator and the rotor. A motor coupled to the rotor rotates the magnetic disk via the rotor. Located in the bearing is a lubricant having a low relative electrical permittivity.
