ABSTRACT:
A servo accelerator for an optical drive includes input and output (I/O) terminals that receive an input signal from a processor of the optical drive. An error circuit generates an error signal based on a sensed characteristic of a laser beam. A compensation circuit generates a compensation signal based on the input signal and the error signal. A servo output adjusts the sensed characteristic of the laser beam based on the compensation signal.
