ABSTRACT:
A magnetic disc apparatus includes a magnetic recording medium and member for recording/reproducing information in/out of the magnetic recording medium, the magnetic recording medium including a recording layer of a magnetic thin film formed on a non-magnetic substrate, and a non-magnetic protective layer formed on and thicker than the recording layer. The particular construction permits diminishing the thickness of the recording layer, making it possible to achieve a high density recording.
