Abstract

PURPOSE:To polish the surface of a coat uniformly and to reduce the number of reciprocating times of a polishing head by forming an interference material between a polishing tape and a base to which the tape is to be fitted. CONSTITUTION:In the head to be used for the polishing of the surface of the coat which is one of magnetic disc manufacturing processes, a silicone rubber film is formed as the interference material 4 between the base part 2 on the leading end of an arm 1 and the polishing tape 3. The surface of the magnetic disc 5 is polished by reciprocating the polishing head in the radius direction of the disc 5 while rotating the disc 5, so that the coat on the surface of the disc 5 can be evenly polished for a short time.

μｍ程度とかなり大きい欠点がある。Prior Art and Problems In order to remove protrusions on the coating surface of a magnetic disk, an abrasive tape attached to the base is moved back and forth in the radial direction of the disk while rotating the disk. , polish the coating surface with abrasive tape. However, since the base portion of the conventional head is a flat plate having rigidity, it is difficult to maintain uniform spacing and contact with the surface of the coating film having minute irregularities. Therefore, uniform removal of protrusions cannot be achieved, so the number of reciprocations between polishing and de is 10 to 10 times.
15 times are required, and the height of the remaining protrusion is 0.15
It has a rather large drawback of about μm.
