摘要:
In one embodiment, an optical read/write apparatus includes first and second optical pickups 2a, 2b and a control section. The first optical pickup 2a includes a first lens 3a that condenses a light beam emitted from a first light source onto an optical storage medium, and a first lens actuator that can shift the first lens 3a in a track crossing section with respect to a middle position. The second optical pickup 2b includes a second lens 3b that condenses a light beam emitted from a second light source onto the optical storage medium, and a second lens actuator that can shift the second lens 3b in the track crossing section with respect to the middle position. The control section makes the lens actuators operate so that as the magnitude of shift of the first lens 3a increases, that of the second lens 3b decreases.
