GLASS SUBSTRATE FOR MAGNETIC DISK APPARATUS |
摘要 |
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 murad/mm where W is a width of the magnetic head slider.
