Paper Abstract

The Electrooptic Beam Scanner is a solid state device developed at Carnegie Mellon's Data Storage Systems Center (DSSC) that is capable of scanning a laser beam approximately +/- 1 - 3 degree(s) at frequencies of at least 200 kHz. The optical group of the DSSC is currently employing the scanner as a fine actuator for high performance optical data storage systems. This paper discusses several aspects of that research, including multi-track scanning for increased data rate, controller for two stage actuator systems, and feedforward control for ultra-fast seeks.
