摘要

A magnetic disk substrate according to an embodiment includes two main surfaces and an outer circumferential edge surface. In the magnetic'disk substrate, the outer circumferential edge surface includes two chamfered surfaces that are respectively connected to the main surfaces, and a side wall surface that is curved and extends to protrude outward between the two chamfered surfaces. The side wall surface has a radius of curvature of 1100 Irm or more on a cross'section of the magnetic-disk substrate extending along a plate thickness direction of the magnetic-disk substrate.
