Patent ID: 7811499

Claim:
A method, comprising: bringing a thermal-mechanical probe into proximity with a layer of resin multiple times to induce deformed regions at points in said layer of said resin, said resin comprising one or more polyaryletherketone polymers cross-linked by one or more reactive diluent groups, said resin having a glass transition temperature of less than about 220° C., said thermal mechanical probe heated to a temperature of greater than about 100° C., said thermal mechanical probe heating said points in said layer of said resin and thereby writing information in said layer of said resin; bringing said thermal-mechanical probe into proximity with said points to read said information; bringing said thermal-mechanical probe into proximity with one or more of said deformed regions in said layer of said resin, said thermal mechanical point heated to a temperature of greater than about 100° C. and heating said one or more of said deformed regions, thereby deforming said one or more of said deformed regions in such a way as to eliminate said one or more deformed regions, thereby erasing said information; repeatedly writing, reading and erasing information at said points in said layer of said resin; wherein said resin has a glass transition temperature of less than about 220° C.; wherein each of said one or more polyaryletherketone polymers has the structure: wherein R 1 is wherein R 2 is selected from the group consisting of wherein R 3 is selected from the group consisting of mono(arylacetylenes) wherein n is selected to provide a molecular weight for each of said one or more polyaryletherketone polymers from about 1000 Daltons to about 20,000 Daltons; and wherein each of said one or more reactive diluents is selected from the group consisting of poly(arylacetylenes), poly(arylacetylene) ethers, poly(arylacetylene) poly ethers,
