Abstract: Apparatus and slide cassette for removably retaining or securing a slide. The cassette includes trays for holding a slide. Each tray has a retaining lip at an end thereof. A first edge of a slide contacts a support member within the cassette when the slide that is placed in a slot. The support member can be an elastomeric member, a spring, a foam member, or an insert with slide retention surfaces. The support member pushes or urges the slide in the opposite direction so that an opposite edge of the slide contacts the retaining lips of the trays. As a result, the slide is removably retained or secured on the trays and between the retaining lips and the support member(s).

Abstract: An automated cartridge library (30) comprises a magazine mounting assembly (60) which holds at least one magazine (70) to a library frame (32), the magazine accommodating at least one cartridge (90) of information storage media. A cartridge transport system (40) transports cartridges between the magazine and a drive section (38). The magazine mounting assembly (60) comprises a magazine mounting surface (100) having a reflection region which is of contrasting reflectivity with another region of the magazine mounting assembly. A magazine guide flange (112) extends from the magazine mounting surface and has a label-bearing facet (123) formed thereon for each cell of the magazine, each facet being aligned with a corresponding cell. The magazine mounting assembly (60) further has two side walls (103) extending from a rear of the magazine mounting surface, planes of the two side walls being angularly inclined toward one another whereby a rear section of the magazine mounting assembly forms a wedge.
