The apparatus comprises a cassette magazine (14) containing a number of compartments (22-1 to 22-25) with cassette carriers (24-1 to 24-25), an optical reading device (26a) with an input slot (27a), and a means of transporting cassettes (12) between the magazine (14) and the reader (26a). Preferably, a transport mechanism (20, 30), driven by a circuit (51), )collects the cassette (12) from the magazine (14) and delivers it to the input slot (27a). Ideally, the transporter (32) should accommodate two cassettes, and a second optical reading device (26b) with a second input slot (27b) is provided. A device (50) detects the position of the transporter. USE - Optical disc information retrieval equipment.
