Abstract

A method for producing a magnetic disk substrate can reduce scratches on the substrate surfaces after polishing while ensuring a high polishing rate. The present disclosure relates to a method for producing a magnetic disk substrate. The method includes a polishing process for polishing a substrate to be polished with a polishing liquid composition containing abrasive grains and water. The abrasive grains are particles with which a cutting depth falls in the range of 5 nm to 25 nm. The cutting depth is a depth of depression formed when a surface of the substrate is cut away by the abrasive grains.
