Abstract
An optical disk () includes several tracks () that each include a series of optical data elements (). Each optical data element includes several reflective surfaces () with respective different orientations that represent stored information. A detection system () directs a beam from a laser () onto successive optical data elements. The multiple reflective surfaces of each optical data element produce multiple reflected sub-beams that are imaged onto respective portions of a detector (). The position of each sub-beam on the corresponding portion of the detector is determined, to thereby identify the orientation of the corresponding reflective surface and thus the stored information represented by that surface.
