Claims
- 1. A method for forming a data storage media, comprising:
injection molding a substrate comprising surface features, wherein said surface features have greater than about 90% of a surface feature replication of an original master; and disposing a data layer over at least one surface of said substrate; wherein said data storage media has an axial displacement peak of less than about 500μ under shock or vibration excitation.
- 2. The method of claim 1, wherein said substrate comprises a material selected from the group consisting of metal, glass, ceramic, metal-matrix composite, and alloys and combinations comprising at least one of the foregoing materials.
- 3. The method of claim 1, wherein said material comprises aluminum.
- 4. The method of claim 1, further comprising disposing a core within said substrate.
- 5. The method of claim 4, wherein said core further comprises a varied thickness.
- 6. The method of claim 4, wherein said core further comprises a cross-sectional geometry selected from the group consisting of concave, convex, tapered, and combinations comprising at least one of the foregoing core geometries.
- 7. The method of claim 4, wherein said core further comprises a core outer diameter substantially equal to a substrate outer diameter.
- 8. The method of claim 4, wherein said core further comprises a geometry selected from the group consisting of a radial arm, a ring, star-like, and combinations comprising at least one of the foregoing geometries.
- 9. The method of claim 4, wherein said core further comprises at least one hollow cavity.
- 10. The method of claim 4, wherein said core further comprises at least one filled cavity.
- 11. The method of claim 10, wherein said filled cavity comprises a material selected from the group consisting of glass, foams, carbon, metals, ceramics, thermoplastics, thermosets, rubbers, others and composites, alloys, and combinations comprising at least one of the foregoing materials.
- 12. The method of claim 4, further comprising performing said core.
- 13. The method of claim 1, further comprising reinforcing said substrate with a material selected from the group consisting of glass, foams, carbon, metals, ceramics, thermoplastics, thermosets, rubbers, and composites, alloys, and combinations comprising at least one of the foregoing materials.
- 14. The method of claim 1, wherein said data layer has a coercivity of greater than about 1,500 oersted.
- 15. The method of claim 14, wherein said coercivity is greater than about 3,000 oersted.
