Patent ID: 8096148

Claim:
A method for fabricating a magnetic disk, comprising: fabricating a magnetic disk glass substrate containing SiO 2 as a main ingredient thereof, the fabricating comprising: polishing a surface of the glass substrate to produce a polished glass substrate; and inspecting the polished glass substrate to check whether or not, at a topmost surface portion thereof, a given property of a bound energy of a Si atom of the SiO 2 with respect to electrons of the Si atom occupying a 2P orbit of the Si atom as determined by XPS is equal to or less than a predetermined value, wherein the given property is a shift amount of the bound energy and the predetermined value is less than or equal to 0.10 eV; and forming a magnetic recording layer on the inspected polished glass substrate when the inspecting determines that the given property is equal to or less than the predetermined value.
