Patent ID: 8142701

Claim:
A method for producing a nanopattern on an upper side and a lower side of a disc the method comprising the following steps: a) placing the disc on a receiving unit of a device for producing a nanopatterned disc, b) precisely aligning the disc relative to a lower die by means of a separate disc positioning unit in the x-direction, a separate disc positioning unit in the y-direction and a separate disc positioning unit in the z-direction and precisely aligning an upper die relative to the disc or the lower die by means of a separate die positioning unit in the x-direction, a separate die positioning unit in the y-direction and a separate die positioning unit in the z-direction, and c) moving the lower die into contact with the lower side of the disc and the upper die into contact with the upper side of the disc to transfer a defined nanopattern of the nanopatterned lower die onto the lower side of the disc and a defined nanopattern of the nanopatterned upper die onto the upper side of the disc.
