Abstract
Recently an optical disk server is prospective for demand of the performance of the backup storage system and growing capacity of the optical disk. So we are developing a disk changer for the optical disk server. It was developed for miniaturization assuming that it is used in the server rack. The disk changer consists of a carrier and a lift using crossing links. The carrier has two feeders to shorten the disk absent time from the drive, and the feeder is a reliable mechanism using a simple timing belt. And the changer has a turnout slot that changes a disk place from one side of carrier to another side to prevent the carrier protruding. As a result the changer could be miniaturized to 88mm height with 16disks.
