ABSTRACT:
This invention provides an improved method and apparatus for manufacturing magnetic recording media; specifically, that which is to be used in the manufacture of flexible, magnetic recording disks. The process provides a sequence of disorienting magnetic fields in different directions and of diminishing strengths to form a magnetic media in which the magnetic particles are essentially disoriented and the media is, thereby, devoid of modulated signal envelopes.
