| titleOfInvention | Irregular optical disc |
| abstract | (57) [Summary] [PROBLEMS] To store and read normal data material for an optical disc, and to use a central portion from the inside to the outside, Provided is an optical disk having an irregular outer shape including a data ring and an outer body and having two or more convex points at appropriate positions on an optically reflective surface of the optical disk. The maximum outer diameter is 120 millimeters (mm). In order to fix the position of the non-circular optical disk when the optical disk rotates, it is possible to fix the position on a rail provided for a small optical disk having an outer diameter of 80 mm (mm) in the optical disk drive. it can. Since this optical disk has no limitation on the outer shape, more optical disk products for new applications can be developed. |
