  • Sweeper burnish head
    Patent number: 8758092
    Abstract: A skewed burnishing head arrangement is provided for burnishing the surface of a disc. The skewing of the burnishing head relative to the diameter perpendicular to a sweeping direction provides improved wiping action that catches loose particles and surface contamination, as well as performing aggressive asperity cutting and surface conditioning, while preventing particles from being embedded into a disc surface.
    Type: Grant
    Filed: November 16, 2005
    Date of Patent: June 24, 2014
    Assignee: Seagate Technology LLC
    Inventors: Yong Hu, Eric K. Dahlini, Hamid F. Ghazvini, Pranesh K. Swamy
  • Hybrid burnishing head design for improved burnishing of disk media
    Patent number: 7255636
    Abstract: A hybrid burnishing head for processing of surfaces of hard disk media comprises a solid body including a first major surface and a second, opposed major surface comprising a burnishing surface including first and second surface portions, wherein the first surface portion is configured for providing air bearing stability and flyability of the head over the media surface, the second surface portion is configured for providing burnishing of a media surface, and the first and second surface portions are operatively decoupled for simultaneously providing optimized air bearing stability/flyability and burnishing aggressiveness for a particular application.
