Abstract
This invention relates to a method and apparatus for retaining disk-like structures, such as magnetic memory substrate plates, or disks, during machining, cutting, or grinding operations. A fluid is applied to one surface of the disk to retain the other surface of the disk against a chuck at a force which is sufficient to maintain the disk against the chuck during the operations.
