RADIAL POSITION REGISTRATION FOR A TRACKLESS OPTICAL DISC SURFACE |
| 摘要 |
A reference pattern (300, 700) on the non-data side (or label side) (146) of an optical data storage disc (126) enables optical disc devices (102) to register a position of a laser (118, 308) to an absolute radial location on the disc's non-data side (146). The absolute radial location serves as a reference track to which that all radial positioning can be referenced. |
