<p>A rigid disk substrate for a magnetic recording disk is formed of a ceramic-metal matrix composite. A metal-cladding may be included around the ceramic-metal 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.</p> |
