The linear semiconductor substrateorof the present invention comprises at least one desired thin filmformed on a linear substratehaving a length ten or more times greater than a width, thickness, or diameter of the linear substrate itself. Adopting semiconductor as the thin filmforms a linear semiconductor thin film. The linear semiconductor substrateorof the present invention is produced by utilizing a fiber-drawing technique which is a fabricating technique of optical fibers.

A method of manufacturing an optical fiber, comprises applying a UV cured resin to an outer circumference of a running glass optical fiber, forming an accompanying flow composed of an inert gas near a surface of the resin by passing the glass optical fiber immediately after having the resin being applied through an atmosphere of the inert gas, and forming a coating by irradiating the resin coated with the accompanying flow with ultraviolet ray to cure the resin while the glass optical fiber accompanied by the accompanying flow is passed through a UV transmission tube to which a gas containing oxygen is supplied.

A main surface of a glass substrate for a magnetic disk is disk-shaped and has a ski jump on an outer peripheral end portion of the main surface opposing a magnetic head slider to be loaded. A rate of change of angles of tangents to a slope of the ski jump in a radial direction in a range between an inner circumferential side and a transition point on the slope is equal to or less than 10/W &#x3bc;rad/mm where W is a width of the magnetic head slider.
