Optical pickup device, optical information recording device, and optical information recording medium

The invention provides an optical pickup device, an optical information recording device, and an optical information recording medium. There is disclosed the optical information recording device using a multilayer optical disc as a recording medium, in which the number of components of the device is reduced. The optical disc has, e.g., one recording layer with prepits and a plurality of recording layer without prepits. An optical pickup included in the information recording device includes a switchable lens element to focus laser beams to be applied to the multilayer optical disc onto two adjoining recording layers. A tracking error signal offset obtained for a recording layer with prepits is stored. Recording an information signal into a recording layer from which a tracking error signal cannot be detected is performed, while maintaining the accuracy of positioning on track with respect to the prepits based on the stored offset. When reading out an information signal, tracking control based on the prepits of recorded information signals is exerted.
