SOLUTION: Objective lenses 15a and 15b to correspond to recording media 21a and 21b which are different in thickness are disposed in the tangential direction to the recording medium 21 by a holder 31, and are freely movable in the orthogonal direction and the radial direction by a driving body composed of a tracking coil 32 and a focusing coil 33. A carriage 41 is made movably in the radial direction, while a sliding base 37 in the tangential direction, and they are integrally moved with the driving body, so that the use of a separate tracking coil for each objective lens is unnecessitated. A changeover of the objective lenses 15a and 15b is performed in such a manner that the carriage 41 is moved to energize one end of a slider, and hence a sliding base 37 is driven to position the objective lens 15 right above a mirror.  In this case, the centroid of the movable body is formed on a side end surface 101 of the holder 31, and an operation point of electromagnetic force of each of the coils is made to coincide with the centroid.
