A non-magnetic substrate for a magnetic disk includes a substrate main body having two opposing main surfaces, the substrate main body made of glass or aluminum alloy, and a metal film that is formed on the main surfaces and an outer circumferential edge surface of the substrate main body and is made of a material having a loss factor of 0.01 or more. The non-magnetic substrate has a thickness g1+D) of 0.700 mm or less, the thickness (t+O) being the sum of a thickness T of the substoate main body and a thickness D of the metal film, and a ratio D/T of the thickness D of the metal film to the thickness T of the zubstrate main body is 0.025 or more. The outer circumferential edge surface of the substrate main body forming an interface with the metal film has a surface roughness maximum height Rz of 0.5 um or more.
