Method of manufacturing magnetic recording medium

摘要

A method of manufacturing a magnetic recording medium having a disc-shaped flexible slave medium accommodated in a case, onto which servo signals are effectively recorded by a magnetic transfer method with high quality. The method includes a slitting step for cutting an original sheet into discrete webs; a punching step for obtaining a disc-shaped slave medium; a thermo step for removing distortion; a burnishing step for smoothing a surface of the slave medium; a center core attachment step; a magnetic transfer step for performing a magnetic transfer while a master medium is allowed to be brought into close contact with one of the web and the slave medium; an assembly step for incorporating slave medium into the case; a cleaning step for cleaning a surface of the slave medium; a verifying step for checking the servo signals; and a packing step.
