Abstract: PROBLEM TO BE SOLVED: To achieve a high recording density and a large capacity of an optical disk by reducing the generation amount of spherical aberration even if the numerical aperture NA of an objective lens loaded on an optical head is increased. SOLUTION: An optical head 1 used for recording/reproducing in an optical disk 2 including a light transmitting layer 4 formed on a recording layer includes an actuator 14 for a collimator lens. A collimator lens 13 is moved between a light source 10 and an objective lens 16 to cancel spherical aberration caused by thickness errors of the light transmitting layer 4 by the actuator 14 for the collimator lens. In this case, the collimator lens 13 is moved to a position calculated so that a square average of wave surface aberration is minimum corresponding to thickness errors of the light transmitting layer beforehand according to the value obtained from a thickness detection means.

Abstract: PROBLEM TO BE SOLVED: To detect a light transparent layer thickness without a special device by separating the exit light of a light source to two luminous fluxes varying in focal lengths and detecting the light transparent layer thickness by first and second focus error signals of the respective return light rays of the respective separated luminous fluxes reflected by a recording layer and the light transparent layer. SOLUTION: The exit light of the light source 7 is collimated by a collimator lens 9 to parallel beams via a polarization beam splitter 8. These parallel beams are diffracted at the time of passing a hologram element 10 and are separated to zero order light and first order light varying in focus positions. These light beams are condensed by an objective lens 11 and are made incident on an optical disk 2. The zero order light past the hologram element and the diffracted first order light are respectively condensed onto the recording layer and the light transparent layer 4 via the light transparent layer 4 to form spots. These light beams are reflected and are returned in the same route so as to be admitted to a photodetector 12. The focus error signals by the return light from the recording layer and the light transparent layer 4 are detected by first and second photodetecting parts 12a, 12b. As a result, the focus error signals as the deviation quantity from the regulated quantity of the light transparent layer 4 are obtd. and thickness error detection is executed.
