    摘要: The invention pertains to an optical recording medium comprising a homeotropically oriented liquid crystalline polymer film having a T.sub.g between 75-100.degree. C. and a T.sub.c between 110-140.degree. C. and comprising at least one dichroic dye. This homeotropic orientation along with the presence of dichroic dye makes it possible to employ a different technique for writing out and reading data. For, in this case contrast is obtained by the dichroic dye contained in the film being aligned in the same direction as the mesogenic groups of the liquid crystalline polymer. In a virgin film the mesogenic groups, and hence the dichroic dye molecules, are oriented perpendicular to the film's surface, and there is only low absorption of the incident light by these molecules. By local heating or irradiation of the film (e.g., with a laser) the homeotropic orientation is converted to an isotropic one. In the case of an isotropically written trace, the dichroic dye will likewise be isotropically oriented, resulting in a substantially higher absorption of the incident light. The films according to the invention are suitable for use in analogue and digital optical data storage, as well as, of course, combined analogue/digital data storage.
