Method for high density data storage and imaging

A data storage device, comprising:

• a recording medium comprising a resin layer overlying a substrate, in which topographical states of said resin layer represent data, said resin layer comprising a cross-linked copolymer, a first monomer of said copolymer having two
• groups, a second monomer of said copolymer having two
• groups and a pendent phenylethynyl group, said copolymer having two terminal ends, each of said two terminal ends terminated with a
• group;
• a head having two or more thermo-mechanical probes, each thermo-mechanical probe of said one or more thermo-mechanical probes including a resistive region configured to heat a tip of the thermo-mechanical probe in response to electrical current being applied to the thermo-mechanical probe;
• and
• a scanning system for scanning said head across a surface of said recording medium.
