MAGNETIC DISK SUBSTRATES FORMED OF CERAMIC-METAL MATRIX COMPOSITES WITH OR WITHOUT METAL CLADDING |
| 摘要 |
A rigid disk substrate for a magnetic recording disk is formed of a ceramicmetal matrix composite. A metal-cladding may be included around the ceramicmetal matrix composite to form a sandwich structure. The ceramic-metal matrix composite has a composition ranging from approximately 1 to 40 weight % of ceramic and 60 to 99 weight % of metal matrix. The metal matrix material and the metal cladding material are aluminum or an aluminum alloy.
