Abstract
An optical disk apparatus includes a main chassis and a sub-chassis provided on a drawer, and has a skew adjusting mechanism of the main chassis and the sub-chassis which is skew-adjusted with reference to a rotational axis in tangential direction X, which is parallel to a spot trajectory L of an optical pickup and located in the vicinity of the spot trajectory L, and a rotational axis in radial direction Xperpendicular to the rotational axis in tangential direction X. This enables the skew adjustment in which a change in height of the optical pickup is small during the adjustment and distortion is small.
