ABSTRACT:
The present invention relates to a method for checking the quality of a recording on a disk intended to be read with a first wavelength and intended to be recorded with a second wavelength, directly with the second wavelength used by the recording system. According to the invention, the method uses a modified jitter definition when a jitter value of recorded information is measured using light of the first wavelength. A special equalizer takes account of a required asymmetry.
