Abstract
A method and associated apparatus for providing improved data mark formation on an optical disc is disclosed. The amplitude of a laser write beam in an optical recording system is varied during application of the mark. Additionally, the illumination period of the laser is adjusted to account for differences between the actual length of a formed data mark and the desired length of a data mark.
