Abstract
An example data storage medium includes an optical information carrier which comprises a polymer carrier, which is set up to store information, and, additionally, a layer. The layer comprises a dye and can be optically changed locally for the purpose of storing information.
Claims27
A data storage medium, including an optical information carrier which comprises a polymer carrier, which is set up to store information, and, further, as an information storage layer independent of the polymer carrier, a layer which comprises a dye and can be optically changed locally for the purpose of storing information,
- wherein the information carrier is set up so that a frequency range of a read beam for reading information from the polymer carrier is different from a frequency range of a read beam for reading information from the dye layer.
A data storage medium, including an optical information carrier which comprises a polymer carrier, which is set up to store information, and, further, as an information storage layer independent of the polymer carrier, a layer which comprises a dye and can be optically changed locally for the purpose of storing information,
- wherein the information carrier comprises two or more polymer carrier plies through which information units may be read from a preselected polymer carrier ply.
A data storage medium, including an optical information carrier which comprises a polymer carrier, which is set up to store information, and, further, as an information storage layer independent of the polymer carrier, a layer which comprises a dye and can be optically changed locally for the purpose of storing information, wherein the information carrier is wound in a spiral fashion and the polymer carrier comprises a polymer film.
