Abstract
A composition contains abrasive grains, solvent and a fluoride and can be used for accurately texturing a magnetic disk glass substrate. The magnetic disk glass substrate is produced using a method that includes the steps of pressing the surface of a magnetic disk glass substrate against the surface of an object for sliding contact at a pressure falling within a range of 0.98 to 196 N, feeding the composition onto at least one of the surface of the object and the surface of the magnetic disk glass substrate, and rotating the magnetic disk glass substrate while the object remains pressed, to thereby perform texturing of the surface of the magnetic disk glass substrate.
