Abstract: A magnetic-disk glass substrate contains an alkaline earth metal component as a glass composition and includes a pair of main surfaces, and an outer circumferential side edge surface that is a mirror surface. The outer circumferential side edge surface includes a surface having a roughness percentage of 40% or more when a bearing ratio of a roughness cross-sectional area is 50% in a bearing ratio curve of roughness cross-sectional areas obtained when a surface roughness of the outer circumferential side edge surface obtained after the outer circumferential side edge surface is etched by 2.5 ?m is measured.

Abstract: A metal mold for centrifugal casting, the exterior surface of which is provided with a coating in the form of an iron oxide film or a film containing calcium as the main ingredient. Such a coating is preferably formed so as to substantially cover the entire exterior surface. If the coating is an iron oxide film, it is preferable for the film to contain triiron tetraoxide. If the coating is a film containing calcium as the main ingredient, it is preferable for the thickness thereof to be at most 0.4 mm. Furthermore, among films containing calcium as the main ingredient, it is preferable for said main ingredient to be calcium carbonate. By configuring a mold for centrifugal casting in such a manner, the exterior surface of the metal mold can be uniformly cooled, and deformation of the mold can be suppressed.

Abstract: A method for processing a sample using an electrically neutral reactive cluster is provided. The surface of a sample is processed by jetting out a mixed gas that is composed of a reactive gas and a gas with a boiling point lower than that of the reactive gas from a gas jetting part of a vacuum process room in which the sample is placed by a pressure in a range in which the mixed gas is not liquefied, in a predetermined direction, while adiabatically-expanding the mixed gas, thereby generating a reactive cluster and jetting the reactive cluster against the sample in the vacuum process room.
