发明名称 METHOD FOR MANUFACTURING GLASS SUBSTRATE FOR MAGNETIC DISK AND METHOD FOR MANUFACTURING MAGNETIC DISK
摘要 <p>The present invention provides a method whereby not only the machining speed can be improved during a grinding process utilizing a stationary grinding wheel, but stable grinding can also be enabled. In the present invention, during a grinding process for grinding a main surface of a glass substrate, the main surface of the glass substrate is ground by using a grinding tool that has grinding abrasive grains, a binding material for binding the grinding abrasive grains together, and dispersed grains that are harder than the binding material yet softer than the grinding abrasive grains, wherein the grinding abrasive grains and the dispersed grains are bound together in a dispersed state in the binding material.</p>
