Method for high density data storage and read-back

A data storage device, comprising:

• a recording medium comprising a layer of a resin overlying a substrate, in which topographical states of said layer of said resin represent data, 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.;
• and
• a read-write head having one or more thermo-mechanical probes, each of said one or more thermo-mechanical probes including a resistive region for locally heating a tip of said thermo-mechanical probe in response to electrical current being applied to said one or more thermo-mechanical probes;
• and
• a scanning system for scanning said read-write head across a surface of said recording medium.

A composition of matter comprising a cured resin comprising:

• one or more polyaryletherketone polymers;
• and
• one or more reactive diluents cross-linking said one or more polyaryletherketone polymers;
• wherein said cured resin has a glass transition temperature of less than about 220 wherein each of said one or more polyaryletherketone polymers has a structure:
• (i) a linear first sequence of first monomers, said first sequence terminated by first and second terminal groups, each first monomer represented by the structure —R1—O—R2—O—, said first terminal group represented by the structure R3—O—, and said second terminal group represented by the structure —R1—O—-R3, or
• (ii) a linear second sequence of second monomers, said second sequence terminated by said first terminal group and a third terminal group, each third monomer represented by the structure —R2—O—R1—O—, and said third terminal group represented by the structure —R2—O—R4,
• wherein R1 is selected from the group consisting of
• wherein R2 is selected from the group consisting of
• wherein R3 is selected from the group consisting of mono(arylacetylenes),
