摘要： A hard disk drive has an information recording medium that is rotationally driven for recording and/or reproducing information and a rotor hub that supports the information recording medium. The rotor hub has a flat mounting surface disposed in an outer circumferential portion thereof and on which the information recording medium is mounted so as to contact an edge portion of the mounting surface. The mounting surface is made of stainless steel containing a machineability improving additive, except for selenium and tellurium, for improving the machineability of the mounting surface. At least one of the edge portion or a portion of the mounting surface in the vicinity of the edge portion contains surface pores formed by component particles of the additive falling from the mounting surface. Each of the pores has a length less than 10 μm in a circumferential direction of the mounting surface.

摘要： An electromagnetic generator includes a magnet assembly having permanent magnets magnetized in a direction of stacking so that surfaces thereof corresponding to the same pole face each other. A solenoid coil is positioned around the magnet assembly so that a position of the solenoid coil relative to the magnet assembly can be changed. Holding parts hold the solenoid coil so that a center of the solenoid coil in a winding axis direction corresponds to a plane position where the surfaces of the permanent magnets corresponding to the same pole face each other at a stop position. Repulsive magnets generate magnetic repulsive forces that maintain the magnet assembly separated from the repulsive magnets. A length of an end face of each permanent magnet in a direction perpendicular to the winding axis direction is equal to or larger than double a length of the permanent magnet in the winding axis direction.
