<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a substrate for a magnetic disk, applicable regardless of the shape, material quality and hardness of polishing carrier in polishing the glass substrate using the polishing carrier, and preventing the occurrence of flaw on the outer end face of the glass substrate, a glass substrate for a magnetic disk obtained by the above method to have excellent characteristics, and a manufacturing method of a magnetic disk and a magnetic disk, using the above substrate. <P>SOLUTION: In holding the glass substrate with polishing carrier and polishing the same, polishing is performed using polishing carrier in which the inside surface coming into contact with the outer end face of the glass substrate is coated with resin. In this manufacturing method of the substrate for the magnetic disk, preferably the resin is thermoplastic or thermosetting resin. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
