Abstract: A magnetic storage apparatus includes a disk-shaped magnetic recording medium, a motor which drives and rotates the magnetic recording medium, a magnetic head, including a first magnetic head element which reads information from the magnetic recording medium, and a second magnetic head element which writes information to the magnetic recording medium, and a bias circuit which supplies a predetermined bias voltage to the first magnetic head element. The magnetic recording medium has a laminated structure including a magnetic layer disposed above a substrate, and a carbon protective layer disposed above the magnetic layer. The bias circuit supplies to the first magnetic head element a voltage which is in a range of −0.2 V to −1.0 V with respect to a potential of the magnetic recording medium.

Abstract: A magnetization measurement device includes: a current supply part supplying a periodically changing current to a sample made of a soft magnetic material with uniaxial magnetic anisotropy in a first direction and a bias magnetic field applied in a second direction crossing the first direction; a light irradiation part irradiating a surface of the sample with linearly polarized pulse light having a predetermined delay time with respect to the current and having a predetermined polarized surface; and a measurement part measuring magnetization of the sample at the delay time based on reflected light of the pulse light reflected by the surface of the sample. These enable the measurement of the change in the magnetization of the sample over time, which corresponds to supply of the periodically changing current.
