摘要： A hologram information reproducing device is described which can reproduce information from a recording medium on which hologram information is recorded, and which can be downsized. In one aspect, when light from a light source is emitted, the light is converted into parallel reference light, by a lens of an optical system. A mirror changes the orientation of the reference light so that it is oriented obliquely downward towards a recording medium. More specifically, as viewed from the top, the mirror changes a path of the light from the light source unit by approximately 90 degrees. In addition, as viewed from the side, the mirror changes the path of the light from the light source unit downward by approximately 45 degrees. Since an interference pattern recorded on the recording medium is a Bragg grating, when the reference light illuminates a recording area of the recording medium, a reproduction light is obtained by Bragg diffraction. The reproduction light is reflected by a reflecting layer of the recording medium and is detected by a photodetector 13.

摘要： A first virtual axis orthogonally intersects with a second virtual axis, and a third axis (axis passing a support center point) vertical to the first and second virtual axes is permitted to be a reference axis. A magnetic drive mechanism is provided with first magnetic drive sections for applying a drive power to a movable axis, which is supporting an object to be controlled, in a rotating direction of the first virtual axis or in a rotating direction parallel to the first virtual axis, and second magnetic drive sections for applying a drive power to the movable axis, in a rotating direction of the second virtual axis or in a rotating direction parallel to the second virtual axis.
