| titleOfInvention | Glass substrate for disc and disk |
| abstract | The present invention provides a kind of glass substrate for disc and disk, and air-flow can be inhibited to get muddled near the periphery side end of disk, can inhibit disk flutter.The glass substrate for disc is characterized in that, it has a pair of of main surface, the side wall surface for being formed in outer peripheral side end face and the fillet surface between above-mentioned side wall surface and main surface, the roundness of above-mentioned side wall surface is 1.5 μm hereinafter, the difference of the radius of the inscribed circle and circumcircle of multiple contour lines of the side wall surface of including above-mentioned center, different on plate thickness direction multiple positions is 5 μm or less. |
