Method and apparatus for writing data to an optical disc |
摘要 |
The invention provides for a method and apparatus for writing data to an optical disc and comprising recovering an output signal from optical reading head, scaling the said output signal responsive to secondary data derived from the disc by way of the optical reading head and deriving a Land Pre Pits (LPP) signal for use during recording to the disc from the said scaled output signal wherein the said scaling is arranged to increase the LPP signal when the LPP is identified as located adjacent a mark on the disc of low light reflectivity.
