Abstract
In order to have a remarkably planarized substrate easily, a glass thin film is predeposited on a surface of a non-magnetic substrate. The non-magnetic substrate is subjected to heat treatment until the glass thin film is softened to a predetermined viscosity, and then the non-magnetic substrate is cured until the glass thin film is hardened.
