Abstract: A method of manufacturing a patterned data/information storage and retrieval medium in the form of an annular disk having an outer diameter, a central opening defining an inner diameter, and opposed first and second major surfaces, the method comprising inserting a smaller diameter cylindrical shaft of a stamping/imprinting tool in the central opening and biasing the inner diameter of the disk into contact with the cylindrical shaft at a pre-selected location along the inner diameter of said disk during stamping/imprinting of a pre-selected pattern such as a servo pattern in at least one of the first and second major surfaces of the disk, the biasing creating a space between the inner diameter of the disk and the surface of the cylindrical shaft which has a maximum width at a location diametrically opposite said pre-selected location. A disk drive system is then formed by mounting the patterned medium on a drive spindle shaft with the medium biased into contact with the shaft at the pre-selected location along the inner diameter of the medium, whereby proper centering of the servo pattern is provided.

Abstract: A method of performing dip coating of a layer of a resist material on a surface of a substrate, comprising steps of: (a) providing a dip coating vessel having an interior space containing a dip coating liquid comprising a solution of the resist material in a solvent, the dip coating vessel being open at the top thereof; (b) providing a substrate having a surface, immersing the substrate in the dip coating liquid in the vessel via the open top, and withdrawing the substrate from the vessel via the open top thereof, thereby forming a layer of resist material on the surface; and (c) monitoring and maintaining the viscosity of the dip coating liquid supplied to the dip coating vessel at a predetermined value. Also disclosed is an apparatus for performing the method.
