A method is provided for processing a metal foil sheet to produce magnetic recording media. The method comprises providing an elongate metal foil sheet having a first side and a second side. The sheet is advanced through the plurality of processing stations in equal unit length segments such that each segment receives the same treatment to form a magnetic recording medium from each segment. Methods are also provided to prepare the foil surfaces by polishing, texturing, cleaning, and stress relieving, to coat the prepared surfaces with at least one metal layer, to finish the coated layers by buffing, burnishing, and lubricating, and to form disk units from the prepared, coated and finished surfaces.
