A nanoimprinting system incorporates a patterned media contact
architecture to provide a uniform imprinting pressure across the target
imprinting area on a disk substrate. The system leverages the unique disk
substrate characteristic of an inner diameter hole by incorporating a
membrane suspension, gel-pad buffering, and air cushion loading that
exploits the inner diameter hole characteristics of the disk substrate.
This design dramatically increases the uniformity of the pressing
pressure across the target imprinting area. As a result, a simple and
effective improvement of the quality of the patterns imprinted on the
recording disk substrate is realized.
