- 12. The storage media as in claim 1, comprising at least one spin coated, spray coated, or spin and spray coated plastic film.
- 13. The storage media as in claim 1, wherein said plastic film comprises a thermoplastic resin with a glass transition temperature of at least 140° C.
- 14. The storage media as in claim 1, wherein said plastic film comprises at least one thermoplastic resin of the group consisting of polyetherimides, polyetheretherketones, polysulfones, polyethersulfones, polyetherethersulfones, polyphenylene ethers, thermoplastic polyimides, and polycarbonates.
- 15. The storage media as in claim 1, wherein said plastic film comprises at least one thermoset resin comprising embossed surface features.
- 16. The storage media as in claim 1, wherein said plastic film comprises at least one thermoset resin, wherein the at least one thermoset resin at least partially cured during a process to emboss surface features onto the at least one thermoset resin.
- 17. The storage media as in claim 1, wherein said plastic film comprises at least one thermoset resin selected from the group consisting of epoxy, phenolic, alkyds, polyester, polyimide, polyurethane, mineral filled silicone, bis-maleimides, cyanate esters, vinyl, and benzocyclobutene resins.
- 18. The storage media as in claim 1, wherein said thickness is about 0.82 mm to about 1.25 mm.
- 19. A storage media, comprising:
a substrate having a top side and a bottom side; at least one plastic film on each of said top side and said bottom side; and at least one data layer disposed on at least one of said plastic film on each of said top side and said bottom side; and wherein said data layer can be at least partly read from, written to, or a combination thereof by at least one energy field; and wherein said energy field comprises at least one of an electric field, a magnetic field, and an optical field.
- 20. A storage media for data, said media comprising:
a substrate comprising an areal density greater than about 10 Gbits/in2 and an axial displacement peak of less than about 500 μ under shock excitation; at least one plastic film comprising a surface roughness of less than about 10 Å and at least one data layer disposed on said plastic film; wherein said data layer can be at least partly read from, written to, or a combination thereof by at least one energy field; and wherein said energy field comprises at least one of an electric field, a magnetic field, and an optical field.
