Abstract
A cryogenic dynamic cooling apparatus and a cooling method for heat assisted magnetic recording media substrate are provided. The cooling apparatus includes a chamber that is configured to receive a substrate. A substrate holder secures the substrate inside the chamber. The apparatus has a cooling plate that is movable between a retracted position and an extended position inside the chamber. The cooling plate provides clearance for movement of the substrate holder inside the chamber in the retracted position, and the cooling plate cools the substrate in the extended position. Also, the cooling plate is substantially parallel to and spaced apart from the substrate. The apparatus further includes a cryogenic operatively coupled to the cooling plate that is cooled by the cryogenic cooling element.
