METHOD FOR PRODUCTION OF MAGNETIC RECORDING MEDIUM, MAGNETIC RECORDING MEDIUM AND MAGNETIC RECORDING AND REPRODUCION DEVICE |
摘要 |
<p>A method for the production of a magnetic recording medium includes the steps of forming a magnetic layer on a nonmagnetic substrate, injecting atoms into portions of the magnetic layer to cause the portions to be demagnetized or allowed to acquire amorphousness, thereby forming a magnetically separated magnetic recording pattern, the step of injecting atoms including the steps of applying to a surface of the formed magnetic layer an SOG film as a resist, partly removing or thinning the resist, and irradiating the surface with atoms, thereby partly injecting atoms into the magnetic layer through the portions of the magnetic layer from which the resist is removed or in which the resist is thinned.</p> |
