Abstract: PROBLEM TO BE SOLVED: To perform a focus control so that recording and reproducing light focuses on a desired recording layer even when layer identification information is not recorded (formed) on the recording layer. SOLUTION: If the time when a focal position of servo light reaches a reference plane is synchronized with the time when a focal position of the recording and reproducing light reaches a desired recording layer in a focus search operation, the distance between the focal positions of light beams coincides with the distance from the reference plane to the desired recording layer. The distance between the focal positions is adjusted so that those times are synchronized. By controlling the servo light to focus on the reference plane, the recording and reproducing light focuses on the desired recording layer, even when layer identification information is not recorded on the recording layer.

Abstract: PROBLEM TO BE SOLVED: To properly drive recording of an optical recording medium that uses a bulk layer for multilayer recording. SOLUTION: A tilt detection surface is provided behind a bulk layer when seen from a laser incident face of the optical recording medium. The tilt detection surface is for example a surface having a groove. One of two systems of laser beam is controlled so as to focus on the tilt detection surface, to correct tilt on the basis of information on returned light thereof. The tilt is corrected so as not to cause shift of spots of the two systems of laser beam, and information recorded on the bulk layer is associated with address information recorded on a reference surface or on the tilt detection surface. In particular, the tilt detection surface is located in a position where a disk thickness-direction distance from the laser incident face can be made longer (behind the bulk layer), information for the tilt correction is made to be easily obtained from a push-pull signal or the like.

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.
