ABSTRACT:
Disclosed is a magnetic recording medium in which a magnetic layer of a ferromagnetic material, a layer of an organic material and a layer of carbon are formed on a substrate in this order.
The magnetic recording medium has the benefit of remarkably extended life time because peeling and removing of the carbon protective layer can be prevented so that carbon can exerts its own lubricating action during the sliding contact of the magnetic recording medium with a magnetic head.
