Abstract

PURPOSE:To simplify assembling the device, by fixing an optical system to a storage body and by holding one end of this storage body shakably by a frame body and by shaking the storage body around one end in accordance with the signal for focus control or the like. CONSTITUTION:A storage body 2 has a magnet 5 pulled always by the first driving material 8 and the second driving material 11 and a right end 2a fixed to a frame body 1 by a fixing piece 3. Therefore, the storage body 2 is held horizontal for a disc 18. When the light beam is slipped from a proper position by eccentricity of the disc or the like, this slippage appears as an optical change on a photodetector 20, and this change is converted to an electric signal and is inputted to the first driving material 8 and the second driving material 11, and the magnetic focus of an iron core 6 and the second iron core is changed to turn the storage body 2 around the fixing piece 3 vertically and laterally, thereby controlling the position of the light beam and the diameter of the beam spot. By this constitution, assembling of the device is simplified.
