Production of magnetic recording media |
摘要 |
Magnetic recording media possessing a thin magnetic layer are produced by dispersing finely divided magnetically anisotropic material and conventional additives in a solution of a polymeric binder in an organic solvent, applying a layer of the dispersion to a non-magnetizable base by means of a knife-coater, then, if required, orienting the magnetically anisotropic material by means of a magnetic field and drying the applied layer, a high molecular weight organic compound which acts as a thickener being added to the magnetic dispersion.
