Abstract

The yield of magnetic-disk substrates that have undergone polishing processing is increased. A slurry, which serves as the raw material for a polishing liquid used in the polishing processing for polishing main surfaces of a substrate, is passed through a filter that is made of a hydrophobic polymeric material and has an opening diameter of 100 nm or less. The polishing processing is performed using a polishing liquid that is obtained after particles that are included in the slurry and have particle diameters that are larger than an average particle diameter of abrasive particles are removed with the filter.
