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.

A hybrid burnishing head for processing of surfaces of hard disk media, comprising:
- a solid body including first and second opposed major surfaces, said second major surface comprising a burnishing Surface including first and second surface portions, wherein:
- said first surface portion is configured for providing air bearing stability and flyability of said head over said media surface;
- and
- said second surface portion is configured for providing burnishing of a media surface;
- wherein:
- said burnishing surface comprises a first pair of laterally extending side edges and a second pair of transversely extending side edges forming leading and trailing edges of said burnishing head, and
- said first surface portion comprises two continuous rails adjacent said laterally extending side edges and a third continuous rail adjacent said trailing edge.
