ABSTRACT:
Disclosed is a novel optical information storage media having M information storage decks. Each information storage deck has N information storage layers, and each information storage layer has a pair of information storage structures. Each paired information storage structure has a characteristic wavelength and polarization state, and from which recorded information can be read by a laser beam having similar wavelength and polarization-state characteristics. A novel system is provided for reading the optical information storage media of the present invention. In the illustrative embodiment, an optical storage device of the present invention having M.times.N.times.2 information storage layers can be read using only N laser lines (i.e. spectral components), thereby providing a 2M-fold increase in information storage capacity over prior art systems. The information storage and retrieval system of the present invention is completely backward compatible to allow for the reading of conventional CD-ROM devices. Various techniques are disclosed for manufacturing and reading the optical storage devices of the present invention.
