ABSTRACT:
A coma aberration correcting apparatus of an optical pickup includes an optical pickup main body having a photo diode, and an actuator mounted on an objective lens focusing a beam emitted from the photo diode onto a recording medium. The coma aberration correcting apparatus includes a main supporting unit, a holding unit, an optical system, a driving part, and a controller. The main supporting unit detachably supports the optical pickup main body. The holding unit holds and releases the actuator on the optical pickup main body supported by the main supporting unit. The optical system magnifies and photographs the beam emitted from the photo diode through the objective lens of the actuator held by the holding unit. The driving part adjusts a position of the actuator relative to the optical pickup main body. The controller controls the driving part to correct the coma aberration of the objective lens.
