ABSTRACT:
The present invention provides for an apparatus and method of controlling writing a signal to an optical disc in an optical disk system and including the step of generating a feedback signal to dynamically tune the signal output from a laser source, and including generating a plurality of timing signals serving to define a plurality of sampling windows for selecting data samples from RF signals derived from a signal reflected from the disc, generating a plurality of runlength selection signals to allow for measurement of light reflection at required runlength lands or pits, and measuring light reflected at a runlength land or pit in processing means and employing the measured signal as the said feedback signal for the said tuning of the signal source.
