Abstract
In the case when a disk is transported into or out of an apparatus, local contact noise is generated in a drive transmission gear and a clutch portion of a disk loading mechanism. Also, this phenomenon gives rise to problems relating to damage of parts, life of a loading motor and the like. Thus, a disk loading mechanism is provided to perform two operations of driving a disk tray in a disk transportation direction by means of a loading motor provided with a worm gear, via a first wheel gear and a second wheel gear, and also vertically raising and lowering a unit mechanism via a slide plate. In addition, a unit for controlling whirling of the above worm gear is provided to reduce contact noise of the gear and clutch portion and improve the reliability of a disk drive apparatus.
