A detection method and apparatus for reading magnetization information recorded in high density. A metal probe is brought close to the surface of a magnetic recording medium, in which information is recorded as magnetization, with the distance on the order of nanometers. The region is irradiated with an incident light as its polarization direction is modulated, and polarization dependency of a tunnel current or reflected polarization intensity is measured.
