Abstract
A burnishing head comprises at least two rails, each rail having an inner wall and an outer wall. The outer walls are at an angle relative to one another and relative to a central axis of the burnishing head. This angle permits the burnishing head to exhibit improved recovery time if it contacts a disk being burnished. The rail walls are vertical, and the corner between the rail walls and the top surface of the rails is sharp.
