Abstract
PURPOSE:To shorten the access time of an optical pickup, by incorporating two or more optical systems in the optical pickup, and arranging the objective lens of each optical system along the radius direction of an optical disk. CONSTITUTION:The optical disk 1 incorporates two pairs of optical systems A and B, and the optical system A being positioned nearer to the center of the optical disk 1 takes charge of access at an inner peripheral side, and the optical system B separated from the center takes charge of the access at an outer peripheral side. In other words, assuming that the optical system A, when reading track information at the inner periphery of the optical disk 1, receives an instruction to read the track information at the outer periphery next, the optical pickup 10 moves in the radius direction toward the outside. And when another optical system B arrives at a targeted track, the pickup stops, simultaneously, the optical system B reads the track information. In such a way, it is possible to shorten the access time as the optical pickup.
