PRODUCTION OF MAGNETIC RECORDING MEDIUM

摘要

PURPOSE:To remove the contaminant sticking to a recording medium by cleaning the front and rear surfaces of the recording medium on which a magnetic metal is deposited by evaporation by a solvent. CONSTITUTION:Both faces of the magnetic recording medium which is deposited with the magnetic metal by evaporation on both the front and rear surfaces are cleaned by the solvent (e.g.; isopropyl alcohol) to remove the deposits and transferred materials which are the contaminant. Drop-out and head clogging are thereby obviated an a still life is improved.
