Abstract
PURPOSE:To realize a surface working method that causes no flaw on the surface of a substrate, by using a face plate providing a protective plate softer than a magnetic disk substrate. CONSTITUTION:A protective plate 5 made of the resin softer than a magnetic disk substrate 3 and formed plural sucking grooves 5a connected to a sucking means is provided to the front face of nearly a cylindrical main body 2 having a driving shaft 2a and made of Al, Fe, etc. to obtain a face plate 1. The substrate 3 is sucked and held on the surface of the plate 1, and a cutter 6 is protruded toward the arrow A to give a mirror surface process to a surface 3a of the substrate 3. Then the substrate 3 is reversed to suck the side of the surface 3a to the plate 5 to give a mirror surface process to the opposite surface 3a'.
