摘要： The number of revolutions of a disk is once increased to a higher level than a resonance frequency of a rotation support system at the startup of rotation of the disk, and subsequently servo control for a pickup actuator is made to work to read information from the disk. It is possible to increase reproducibility of the disk unbalance correction and improve the apparatus in reliability without generation of vibrations and noises, and to spin the disk at high speed.

摘要： A disk drive apparatus is provided in which there is a disk tray having a disk-receiving face shaped in the form of a circular groove for mounting a recording disk thereon. The disk tray has a plurality of disk holding parts for holding a recording disk onto the disk-receiving face. A disk loading mechanism provides for loading/unloading the disk tray in/out of the apparatus, and a disk position regulator is placed near the disk tray to position the disk when the disk tray is loaded/unloaded. The regulator has a contact surface contacting a part of the rim of a recording disk protruding out of the sides the disk tray.

摘要： 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.
