Document Type and Number:
Japanese Patent JPS5850626
Kind Code:
A
Abstract:
PURPOSE: To stabilize a magnetic recording medium and to achieve mass production by using a magnetic paint contg. magnetic metals at 60W67wt%, thereby obtaining a magnetic film which does not produce any film defect even when the film thickness is increased.
CONSTITUTION: Magnetic paint which consists of magnetic metal powder, a binder such as epoxy resin and a solvent and contains the magnetic metal powder at 60W67wt% is coated on a non-magnetic substrate of aluminum or the like to about 50W100μm thickness by a spinner method or the like and is then cured, whereby a magnetic recording medium for magnetic encoders is obtained.
