Glass substrates for magnetic media and magnetic media based on such glass substrates

摘要

Described are substrates for magnetic media which have excellent surface properties as prepared directly from a slot drawdown glass sheet forming process. The substrate blanks cut directly from the glass sheet, as drawn, require little or no surface treatment for use as substrates for magnetic media, particularly hard disk drives. Also described are methods for preparing such substrates and methods for preparing magnetic media therefrom. Further described are the substrates and magnetic media prepared by such processes.
