Patent ID: 7314833

Claim:
A method for manufacturing a discrete track recording media, the method comprising: forming an imprint resist layer on a substrate; imprinting, on the imprint resist layer, a stamper formed with patterns of protrusions and recesses corresponding to recording track zones and servo zones to transfer the patterns of protrusions and recesses to the imprint resist layer; removing the stamper from the imprint resist layer; and depositing a plurality of media films including a magnetic film on a surface of the subtrate, wherein after the stamper removing or the depositing, liquefied CO 2 is diffused in a process chamber set at a pressure of 2 to 5 atm, liquefied H 2 O is diffused in the process chamber set at a pressure of 0.01 to 1 atm, or a reactive gas selected from the group consisting of liquefied CF 4 , CHF 3 , SF 6 , and C 2 F 6 is diffused in the process chamber set at an arbitrary pressure, to jet spray the liquefied gas onto a surface of the imprint resist layer, and wherein, after the stamper is removed from the imprint resist layer and the plurality of media films including the magnetic film are deposited on the substrate surface, the jet spraying is performed to lift off the remaining imprint resist and the media films deposited on the remaining imprint resist.
