Magnetic recording medium comprising a magnetic Co-Ni-Cr alloy thin layer |
摘要 |
A magnetic recording medium for high density recording comprising a non-magnetic substrate, a Cr undercoat and a magnetic Ni-Cr-Co alloy thin layer formed on the substrate. The magnetic alloy thin layer has a thickness of from 400 to 1200 angstrom and a Cr content of from 3 to 17 atomic percent. As a result, improved magnetic characteristics and corrosion resistance of the medium are ensured.
