Disclosed is a novel multi-layered optical recording media and system for recording and reproducing information data. The multi-layered topical recording media has M information storage decks, and 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. In the illustrative embodiment, the multi-layered optical recording media of the present invention has MxNx2 information storage layers which 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.

A pre-formatted optical data storage tape (10) including an elongated linear polymer layer having at least one pattern of optically readable embossments (114) on at least one surface of the polymer layer, and an optical recording layer covering the pattern of optically readable embossments (114) of the elongated linear polymer layer, wherein the optical recording layer is adapted such that recorded marks (120) may be made in the recording layer by directing a focused source of energy into the recording layer.

A data storage medium includes an information carrier wound onto a winding core in a spiral manner for optically readable information units. The winding core is configured in a spiral manner on its outer contour and has a step. The height of the step is matched to the thickness of the information carrier. The inner end of the information carrier rests on the winding core at the step or in the area of the step.

A method and system of a head for use with a storage media having a first set of read transducers positioned to compensate for shrinkage of the storage media, and a second set of read transducers positioned to compensate for expansion of the storage media.

An anamorphic imaging system is disclosed which maximizes the use of available image area to minimize display magnification and image degradation due to display magnification, reduces the amount of anamorphic squeeze during photography to lower image degradation due to anamorphosis, and in film applications, utilizes a film frame that is only three perforations in height to reduce the amount of original film needed. The frame for either film or digital applications has an aspect ratio of approximately 16:9, is contained within the total available frame area of a three-perforation frame or digital imager, and is sized to maximize image area. In preferred embodiments, the image capture area is approximately 0.900 inches wide by approximately 0.506 inches tall.
