VERFAHREN ZUR HERSTELLUNG VON MAGNETISCHEN AUFZEICHNUNGSMATERIALIEN

摘要

A method of producing a magnetic recording layer on a support comprising simultaneously depositing a ferromagnetic material and a polymer on a support using a vapor deposition technique such as vacuum deposition, sputtering, etc., thereby to produce thereon a magnetic recording layer of a composite film of the ferromagnetic material and the polymer. A further embodiment for producing a magnetic recording layer comprises simultaneously depositing a ferromagnetic material and a monomer or oligomer on the support using a vapor deposition technique, polymerizing the deposited layer, e.g., using a polymerization catalyst or by applying ionizing or electromagnetic rays thereto, to form a composite film of the ferromagnetic material and the polymer. The magnetic recording layer thus obtained in either embodiment can be used for high density recording.
