ABSTRACT:
A record carrier is described for optically writing and reading information, which record carrier is provided with a pre-formed track. This track is formed by a ridge disposedon the substrate surface and the recording layer comprises a dye layer having such a thickness at the location of the ridge that a write beam can produce a maximum optical effect therein, the dye layer being thicker at locations outside the ridge.
