Method for tracking in single-bit holographic data storage

摘要

A system (10) and method for controlling tracking in a holographic data storage system (10), including: impinging a beam (16) on a holographic data disc (12), wherein the beam (16) is reflected (18) from a micro-hologram (124) disposed within the holographic data disc (12); detecting the reflected beam (18) from the holographic data disc (12) by a multi-element detector (90); and analyzing a pattern detected by multi-element detector (90) to generate a tracking error signal (140, 160).
