Abstract
Abstract A disk guide is comprised of a pair of mutually parallel vertical grooves, a disk holder and a mechanism for moving the disk holder vertically. The grooves are formed on mutually opposite sidewalls such that a disk supported by the disk holder can be lifted vertically, supported and guided by the vertical grooves. The disk holder has a disk-supporting top surface which is sloped such that the disk supported thereon leans against a selected one of the vertical sidewalls and hence can be positioned accurately.
