Magnetic record carrier having a thin film of ferromagnetic metal onto a non-magnetic substrate.

摘要

In a magnetic recording medium comprising a thin film type ferromagnetic metal layer formed by physical vapour deposition on a non-magnetic substrate (4), the ferromagnetic metal layer comprises columnar crystals (10) inclined relative to the substrate (4), each of the columnar crystals being formed of ferromagnetic metal particles (11) and oxide particles (12) of the ferromagnetic metal randomly distributed in the columnar crystal. The recording medium has improved signal to noise ratio. IMAGE
