Patent ID: 8038863

Claim:
A method of manufacturing a production stamper for imprinting a recording disk, comprising: generating a patterned layer comprising a hard material and having a first diameter, the patterned layer having a back plane bounded by an outer wall forming a cavity, the patterned layer comprising a hard material, the patterned layer having a first thickness in a range of 1 to 300 microns; and directly bonding an elastomer on the back plane of the patterned layer within the cavity of the outer wall, the elastomer having a second thickness being approximately equal to or greater than the first thickness of the patterned layer, the second thickness being greater than 300 microns, the elastomer having a second diameter being less than the first diameter, wherein the hard material has a hardness value in a range of HV100 to HV1000, and the elastomer having a hardness value in a range of 20 to 55 Shore 00 scale or 10 to 100 on Shore A scale.
