ABSTRACT:
A magnetic recording structure comprises (1) a substrate having an outer surface, and (2) a laminar magnetic recording piece disposed adjacent to at least one part of the outer surface of the substrate, the recording piece comprising a magnetic layer, a color layer and a non-magnetic metal deposition layer interposed between the magnetic layer and the color layer, the magnetic layer being closer to the substrate than the color layer.
The non-magnetic metal deposition layer disposed on the magnetic layer has high hiding power and, even in the form of an extremely thin layer, can effectively hide the color of the magnetic material.
Accordingly, this magnetic recording structure can be produced with a surface of a beautiful color without impairing its magnetic characteristics.
