Abstract

PURPOSE:To obtain a device having a light focusing performance by having the angle adjusting mechanism of an objective lens to turn the objective lens to one axis or two axes between an elastic supporting device and a fixing member. CONSTITUTION:After the temporary assembling of an optical head, focusing is executed onto the same surface as a recording medium surface, for example, onto the glass surface at the opposite side of an objective lens 8 having a suitable reflection factor by a moving coil for driving a focusing direction and a moving coil 9 for driving a tracking direction, and a focusing spot detected by an optical microscope and a CCD sensor on a glass surface focused from an opposite side for the objective lens 8 and the glass surface is observed by a CRT, etc. When the glass surface and the objective lens light axis are not at right angles, the focusing spot is not made symmetrical in every direction viewed from the spot center by the aberration to occur when the glass passes through an optical beam. Thus, the inclination is adjusted so that the aberration can be minimum with the inclination adjusting mechanism by a member 2 for adjusting an angle and a rotary shaft 5.
