Abstract
Abstract Disclosed herein is a carrier for a rigid data storage disk, e.g. an optical, magnetic or magneto-optic disk, for facilitating the transport of such disk within a disk library or the like. Such carrier comprises a generally rectangular frame which is provided with a pair of racks of teeth along opposing lateral edges. Such racks are adapted to be engaged by a toothed conveyor for advancing the carrier along a desired path.
