ABSTRACT:
The invention provides exemplary magnetic recording media, and in particular, flexible metal foil disks, read/write systems having such disks, and methods for making such disks. In one exemplary embodiment, a recording medium is provided which comprises a metallic substrate and at least one sputter deposited film of magnetic material on the substrate. The recording medium has a thickness that is less than about 0.010 inch and the substrate occupies at least 80% of the thickness. Further, the sputter deposited film is adapted to record and reproduce high areal densities of digital data. In one embodiment, such a recording medium is included in a read/write system to provide a unique recording interface that can resist mechanical shock.
