METHOD OF MANUFACTURING SUBSTRATE FOR MAGNETIC RECORDING MEDIUM, AND METHOD OF MANUFACTURING MAGNETIC RECORDING MEDIUM BY USING THIS SUBSTRATE MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To uniformly process a substrate surface and to suppress the formation of abnormal projections even in substrates different in surface energy by using slurry corresponding to the surface energy of the substrate to be subjected to texture processing. SOLUTION: The method of manufacturing the substrate for a magnetic recording medium comprises: a slurry selection process 40 for selecting slurry whose surface tension is controlled so as to make a contact angle with the surface of a substrate to be subjected to texture processing have a value within a specific range; and a texture processing process 50 for applying texture processing the surface of the substrate by using the selected slurry.
