A write analysis system is described for an optical drive, where the optical drive includes an optical storage medium. The write analysis system includes a filter that receives a reflected signal that is based on a reflection of a diffracted laser beam. The reflection of the diffracted laser beam includes a reflection of a first write signal. The filter generates a filtered signal by filtering the first write signal from the diffracted laser beam. The system also includes a read-back module that receives the filtered signal and that compares the filtered signal to a second write signal that was written to the optical storage medium prior to the first write signal.
