摘要： In a case of performing recording/playing with an information recording layer with a first light irradiation, and controlling the recording/playing positions on the information recording layer by a second light irradiating as to a position control information recording layer provided separately from the information recording layer, corrections to shifts in recording positions and playing positions that occurs as a result of shifts in the optical axes of the first and second lights.A disc-shaped recording medium has multiple pit row phases wherein, the pit rows having a spacing between one round of pit formable positions that is limited to a predetermined first spacing are formed in a spiral shape or concentrically, and with pit rows arrayed in the radius direction, the spacing in the pit row forming direction of the pit formable positions is set to positions shifted by a predetermined second spacing. Therefore multiple pit rows can be arrayed in within the width of one conventional track, and a tracking servo can be used for the selected pit rows in accordance with the correction amount of the playing position, in which case corrections can be made with high precision that is narrower than one track width.

The apparatus includes a current position detection unit for detecting the current recording/reproducing track position of a head device on a recording surface of a disc-shaped recording medium, a target value outputting unit for outputting a value changed as a second power of the time as the movement target position data from the current track position as far as an object track position, and a comparator unit supplied with an output signal from the current position detection unit and an output signal from the target value outputting unit and adapted for comparing the two output signals to each other. Seek control of the head device is performed on the basis of an output signal from the comparator unit.
