PRODUCTION OF MAGNETIC RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To form a stripe-shaped texture having extremely shallow depth by forming a resist thin film having a prescribed uneven pattern on a master dish of a stamper, then forming a plated layer by laminating a first plated layer formed by an electroless plating method and a second plated layer formed by an electrolytic plating method and peeling off the plated layer from the master disk to produce the stamper having the inverted uneven pattern. SOLUTION: A photoresist layer 11 having the prescribed uneven pattern is formed on an almost disc-shaped glass substrate 10 having a hole of a prescribed diameter in the center. The first plated layer 13 is formed into a thin film shape on the glass substrate 10 having the formed layer 11 by the electroless plating method by using NiP or the like. The second plated layer 14 is formed on the layer 13 by changing the electroless plating method to the electrolytic plating method when the layer 13 reached to the prescribed thickness to form the plated layer 15. The layer 15 is peeled off from the substrate 10. The front surface of the peeled layer 15 is washed and the rear surface is polished to prepare the stamper.
