Abstract:
Various apparatus and related methods are disclosed that are capable of detecting surface defects on an optical storage media. One example of an apparatus is configured to direct at least one light signal, which may be from one or more lasers, on an outer surface of an optical storage medium, such as a CD, DVD or the like, which includes encoded data. The light encounters both the optical storage media surface as well as any smudges, scratches, dents, or other defects thereon. Some or all of the light reflected from the defects and the surface are detected by one or more detectors, which may be a photodiode. The detector(s) produce an output signal commensurate with the detected reflected light, which output is processed to determine whether the encoded data may be accurately read from the optical storage media.
