In one aspect the present invention provides a storage medium for data, the storage medium comprising: a) a substrate, a physical portion of which comprises at least one polyimide, and b) at least one data layer on the substrate. The substrate comprising a polyimide exhibits low axial displacement and beneficial damping characteristics.

Data storage medium comprising polyimides

A method for manufacturing an embossed surface including a polymer composition having reactive moieties and a first glass transition temperature of T. The method includes embossing the surface at temperature T; and raising the first glass transition temperature Tof the embossed polymeric surface to a second glass transition temperature Tsuch that T&#x3e;T. In another embodiment, a method for improving the release of a polymeric surface from an embossing tool includes incorporating of one or more of fluorine atoms, silicon atoms, or siloxane segments into the backbone of the polymer. The methods are particularly suited for direct patterning of photoresists, fabrication of interdigitated electrodes, and fabrication of data storage media.

Embossing process

A method for creating an optical structure includes forming a layer of chalcogenide material upon a substrate, and applying a patterned stamper to the layer of chalcogenide material, in the presence of heat, the patterned stamper causing the layer of chalcogenide material to reflow such that stamped features of the patterned stamper are transferred onto the layer of chalcogenide material. The stamped features onto the layer of chalcogenide material are used to form one of an optical waveguide, an optical mirror, digital video disk data, compact disk data and combinations comprising at least one of the foregoing.
