A loader data carriers, such as magnetic tape cartridges, of the type having a housing with a data reader therein which is movable over a magazine containing a number of data carriers, so as to be positionable above a selected data carrier for transfer between the magazine and the data reader, has a drawer which carries the magazine and which is slidable into and out of the loader housing. A drive motor is contained in the housing for moving the data reader over the drawer, and the reader carries transfer assemblies, such as roller-driven belts, to effect the transfer of the data carriers between the magazine and the reader. The drawer has engagement elements mounted thereon which can engage the transfer assemblies, so that the same motor which is used to move the data reader over the drawer can be used to slide the drawer into and out of the loader housing, when the transfer assemblies are engaged with the engagement elements. The loader housing may be formed by a single extruded tube, with interior glide elements thereon on which the data reader and the drawer are respectively movably mounted by roller assemblies.
