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.
Claims18
An optical data store containing a data storage layer, comprising a light-sensitive material which is an organic or biological polymer which is non-toxic and biodegradable, and, if appropriate, is embedded in a suitable matrix material, the data storage layer having photo-inducible anisotropy, for the induction of which a threshold value of the optical intensity has to be exceeded.
A method of storing data comprising the steps of:
- providing an optical data store that is embedded in a matrix material, the optical data store containing a data storage layer comprising a light-sensitive organic or biological polymer that is non-toxic and biodegradable, wherein the data storage layer has photo-inducible non-reversible anisotropy, induction of which requires a threshold value of the optical intensity to be exceeded;
- and
- writing data to the optical data store by inducing the photo-inducible non-reversible anisotropy using a recording light having an optical intensity exceeding the threshold value.
