Abstract
An optical storage system includes an optical head configured to split a light beam into a higher power main beam and a lower power side beam. The system also includes a controller. The controller is configured to modulate the higher power main beam according to writing commands to write to an optical medium while processing first data resulting from the lower power side beam being reflected from the medium and second data obtained from a look-up table that maps the writing commands to digital representations of filtered writing strategy waveforms to remove noise from the first data caused by the higher power main beam and generate output indicative of written data directly after writing.
