Abstract: The present invention provides a manufacturing method of a sheet glass material excellent in flatness. A manufacturing method of glass substrate for magnetic disk including a pair of principal surfaces, the method comprising the steps of: dropping process for dropping a lump of molten glass; pressing process for forming a sheet glass material by performing press forming to the lump while sandwiching the lump from both sides of the dropping path of the lump with facing surfaces of a pair of dies, the pair of dies being set to substantially the same temperature; and processing process for processing the sheet glass material, while the lump drops down while revolving around its dropping axis.

Abstract: The present invention relates to a silicon mold device for production of an optical element in a high temperature environment and a preparation method thereof. The silicon mold device utilized in this invention features a symmetrical structure, ensuring uniform deformation during heating to mitigate eccentricity issues. Additionally, a stepped silicon mold core is employed and secured by applying force through an electrode pressure plate, thereby enhancing overall parallelism. Support columns assist in the closure and alignment of the upper and lower molds. Each support column can be individually adjusted for parallelism, facilitating the enhancement of precision and reliability in the preparation of optical elements.

Abstract: The present invention provides a method for efficiently manufacturing a glass substrate for magnetic disk having good accuracy of a surface irregularity and an impact resistance. The method includes the steps of: performing press forming to molten glass to prepare a sheet glass material, the sheet glass material having a roughness of the principal surface of 0.01 μm or less and target flatness of a glass substrate for magnetic disk; chemically strengthening the sheet glass material by dipping the sheet glass material in a chemically strengthening salt, thereby preparing a disk substrate; polishing the principal surfaces of the disk substrate. A thickness of the sheet glass material prepared in the press forming step is larger than a target thickness of the glass substrate for magnetic disk by a polishing quantity of the principal surface polishing step.
