METHOD OF MANUFACTURING MAGNETIC RECORDING MEDIA, MAGNETIC RECORDING MEDIA AND MAGNETIC READ/WRITE DEVICE

摘要

A manufacturing method which is capable of easily and inexpensively manufacturing discrete track-type magnetic recording media is provided. A method of manufacturing magnetic recording media having a main surface on which magnetic tracks 4 are disposed in a substantially concentric arrangement and on which grooves 5 for magnetically separating radially adjoining magnetic tracks 4 from one another are formed is characterized by forming on a flat substrate 1 at least a magnetic recording layer 2 so as to fabricate a workpiece 1a, then pressing a stamper having protrusions corresponding to the grooves 5 against a main surface of the workpiece so as to transfer the shape of the protrusions to the workpiece and form grooves 5 between the magnetic tracks 4.
