摘要： An inner peripheral edge of a toroidal glass substrate for a magnetic disk is subjected to mechanical polishing in such a manner that the surface roughness is no greater than 9 nm in terms of Rmax. Then, the inner peripheral edge is subjected to chemical polishing to remove at least 2 μm of a surface layer. The inner peripheral edge has a non-conventional mirror-finished surface obtained by mechanical polishing. Thus, sufficient ring strength is obtained even when the chemical polishing depth is smaller than in the past. A polishing depth of less than 5 μm is sufficient.
摘要翻译：对于磁盘的环形玻璃基板的内周缘进行机械抛光，以Rmax表示的表面粗糙度不大于9nm。然后，对内周缘进行化学抛光，以除去至少2μm的表面层。内周边缘具有通过机械抛光获得的非传统镜面抛光表面。因此，即使化学研磨深度比以往更小，也获得了足够的环强度。小于5μm的抛光深度就足够了。

摘要： A method for the manufacture of a preform of barium containing heavy metal fluoride glass comprising a core and a jacket for drawing infrared light waveguides for optical communications technology by casting molten glass onto a predetermined body of solid glass. Hitherto, such a method was executed such that molten core glass was cast into a tube of jacket glass. In order to achieve thicker preforms, one proceeds such here that a solid row of the core glass is surrounded with molten jacket glass. The boundary surface between core and jacket of the generated preform can be improved in the method disclosed herein that the surface of the solid rod is etched before being surrounded with the jacket glass. A nearly perfect boundary surface is obtained by etching with a ZrOCl.sub.2 solution.

摘要： A method of finishing a glass surface to a close tolerance and a substantially blemish-free state using a moving polishing lap and an aqueous treatment liquid containing inert abrasive particles, in which the treatment liquid also contains a bifluoride which reacts with the glass to form an insoluble silicofluoride or fluoride, an acid supplying hydrogen ions and a solubility suppressant which ensures that the silicofluoride or fluoride separates out on the glass surface, whereby the lap and inert particles remove the silicofluoride or fluoride from high portions of the glass surface and thereby allow further reaction and glass removal in those areas until the desired finished form of the glass surface has been achieved, whereupon the supply of treatment liquid is stopped and immediately replaced by a supply of an alkaline neutralizing solution, e.g., of sodium carbonate, containing inert particles and the surface is finally washed to remove the alkaline solution and any remaining neutralized treatment liquid.
