    摘要： A plastic substrate is processed by a functional water obtained by electrolysis of water or functional water containing active oxygen or active hydrogen for a predetermined time period to selectively remove an alkali and/or halogen component in a surface layer of the plastic substrate to stabilize or remove oligomer in a resin matrix, whereby deterioration of resin and deterioration of properties of a recording medium caused by a remaining unreacted catalyst used for processing the plastic substrate surface or the like can be prevented and the adhesion strength and the durability of a recoding coating to be formed on the substrate are improved.

    摘要： To propose a method of cleaning a surface of a glass substrate fabricated by a process of strengthening a surface thereof by alkaline ion exchange reaction by selectively removing alkaline metal on the surface by cleaning the surface by using an activated ionic water produced by electric polarization and as a result, to provide a glass substrate for a magnetic disk having a magnetic medium with insignificant corrosion and excellent S/N ratio, in cleaning a glass substrate for a magnetic disk using a glass substrate pulled up from a chemically strengthening treatment solution produced by an alkaline ion exchange reaction, after a final polishing step of fabricating the glass substrate for a magnetic disk, the glass substrate is cleaned by an activated anodically electrolyzed water produced by electric polarization to thereby selectively remove the alkaline metal at the vicinity of the surface.
