Abstract
An optical data store is specified, having a data storage layer with a non-toxic and biodegradable polymer as light-sensitive storage medium which has photo-inducible anisotropy, for the induction of which a threshold value of the optical intensity has to be exceeded. The light-sensitive material is preferably bacteriorhodopsin which, by way of example, is immobilized in a manner embedded in a suitable matrix material or, if appropriate, in a crosslinked manner. The storage medium permits a high storage density and can be applied in a simple manner, for instance by printing onto a substrate.
