摘要：The system in accordance with the invention comprises a cassette (101) and anapparatus (102). The cassette (101) has a housing (110) which accommodates two reelhubs (121 and 122) and an optical tape (140). The optical tape (140) extends past atransparent optical window (118) which is accessible from one side (113a) of the cassette.The reel hubs (121 and 122) are connected to comparatively large winding wheels (131and 132, respectively). The wheel surfaces (131a and 132a) of the winding wheels (131 and132) are engageable with and drivable by driving surfaces (181a and 182a, respectively) ofthe apparatus (102) via openings (113b and 113c). The driving surfaces (181a and 182a)form parts of drive wheels (181 and 182) mounted on shafts of the electric motors (183and 184). The apparatus (102) further comprises an optical head (172) for writing and/orreading information on/from the optical tape (140) via the optical window (118).
