Abstract
An optical disc apparatus includes a main guide shaft and a subsidiary guide shaft disposed so as to guide movement of a sliding base which holds an optical pickup. The optical pickup enables information recording and reproducing operations on an optical disc. The main guide shaft and the subsidiary guide shaft are configured so as to suppress vibrational resonance caused between the main guide shaft and the subsidiary guide shaft.
