OPTICAL INFORMATION RECORD MEDIUM

摘要

An optical information record medium ( 1 ) has at least one information layer ( 100 ) comprising a transparent substrate wherein nano-elements ( 101 ), for example nanotubes, having a symmetry axis are embedded. Information can be recorded by orienting the axes of the nano-elements within selected regions ( 110,120 ) in the same direction. Information can be read from the medium by means of a radiation beam having a polarization direction (p 1 , p 2 ) corresponding to the said direction of the nano-elements, thereby creating absorptive information areas ( 110,120 ). In this way high information density can be achieved.
