    摘要： A polarized electromagnet that can suppress magnetic flux leakage in a position that does not affect the suction force between an interior yoke and an exterior yoke, and increase the suction force of a permanent magnet is provided. A polarized electromagnet includes a spool 11 around which an electromagnetic coil is wound, a movable plunger 15 penetrating the spool, an interior yoke 22 fixed on the outer side of the spool, an exterior yoke 21 disposed to maintain a predetermined interval on the outer side of the interior yoke, and a permanent magnet 24 disposed between the interior yoke and exterior yoke. The exterior yoke 21 is formed of a pair of end plate portions 21a and 21b opposing either end of the spool, and a linking plate portion 21c linking the end plate portions, and the interior yoke 22 has a first opposing plate portion 22a opposing the linking plate portion 21c of the exterior yoke, and second opposing plate portions 22d and 22e opposing the one end plate portion 21b of the exterior yoke. The first opposing plate portion and second opposing plate portions are linked without coming close to the exterior yoke.

    摘要： A main surface of a glass substrate for a magnetic disk is disk-shaped and has a ski jump on an outer peripheral end portion of the main surface opposing a magnetic head slider to be loaded. A rate of change of angles of tangents to a slope of the ski jump in a radial direction in a range between an inner circumferential side and a transition point on the slope is equal to or less than 10/W μrad/mm where W is a width of the magnetic head slider.
