摘要:
A method for simultaneously forming a plurality of organic-solvent-based magnetic layers on a moving support for the manufacture of a magnetic recording medium or the like. The surface tension of a solvent used to form the uppermost of the layers is made lower than that of the other layers. The most preferred range of the surface tension of the solvent which forms the uppermost layer is in a range of 0.1 to 3 dynes.
