Field of the Invention The present invention relates to an optical pickup apparatus in which a semiconductor laser is used for information recording and/or reproducing, and an objective lens having an aperture NA on the same order of 0.7 is used to achieve a high density recording and/or reproducing. 2. Description of the Prior Art Recently, a high-speed and high-density recording and/or reproducing apparatus has been widely used with respect to, for example, an optical disk such as a magneto-optical disk, a phase change type optical disk, a holographic disk, a photo-electromagnetic disk or the like. However, in the conventional optical pickup apparatus, in the case where an objective lens having a high NA (Numerical Aperture) is used, it is impossible to control the characteristics of the objective lens for fine adjustment. This causes a phase variation of the incident light beam, leading to a focus error. As a result, a spot formed on an optical disk can not be focused in a desired position, and the focus offset angle.theta. increases. For example, in the case where the objective lens having an NA of 0.7 (NA: 0.7) is used, a spot formed on an optical disk surface by a focused beam is about 2.mu.m for the highest layer, and a depth of focus.+-.2.mu.m for the highest layer. When an objective lens having a NA of 0.55 is used, the depth of focus.+-.4.mu.m, thereby not possible to be detected. For this reason, focus adjustment by an actuator is carried out during a readout operation or during a recording or a reproducing operation. However, the focus error is not limited to one formed due to a variation of the NA of the objective lens, it is a problem due to an error in the thickness of a film forming an optical disk such as a protective layer, a reflecting layer, a layer reflecting a light for tracking or the like, a difference of refractive indices between a protective layer and an optical disk, a variation of a material, a variation of a thickness of the objective lens, a variation of NA due to a temperature fluctuation, a high frequency vibration or the like. In order to solve the above-described problem, in the conventional optical pickup
