ANORDNING FOR ALSTRING AV MAGNETISKT FLODE I ETT MAGNETISKT MEDIUM |
摘要 |
A process for generating a magnetic induction field within a magnetic medium. A magnetic excitation field and a selection wave are caused to act simultaneously at each point on a path of at least one non-saturated portion of the magnetic medium, in such manner as to modify the magnetic properties of the medium at this point by degrading them and thus producing therein the induction field. The process is applicable to devices for generating a magnetic field utilized in magnetic data recording systems, wherein the magnetic medium is of a "degraded type". |
