Embodiment Construction
[0017] FIG. 1 shows a disc-shaped record carrier 11 with a track 9 and a central hole 10 . The track 9 is a series of positions representing (to-be) recorded marks of information arranged in a spiral of revolutions constituting substantially parallel tracks on the information layer. The record carrier may be optically readable, a so-called optical disc, and have an information layer of the recordable type. Examples of recordable optical discs are CD-R, CD-RW, writable versions of DVD such as DVD+RW and high-density rewritable discs using blue lasers called Blue-ray Discs (BD). More details on DVD discs can be found in reference ECMA-267: 120mm DVD-Read-Only Disc (1997). Information is represented on the information layer by recording optically detectable marks along the track, for example crystalline or amorphous marks in a phase change material. The track 9 on a recordable type of record carrier is represented by a pre-emboss track structure which is provided during manufac...
