Abstract
The system in accordance with the invention comprises a cassette (101) and an apparatus (102). The cassette (101) has a housing (110) which accommodates two reel hubs (121 and 122) and an optical tape (140). The optical tape (140) extends past a transparent 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 (131 and 132, respectively). The wheel surfaces (131a and 132a) of the winding wheels (131 and 132) are engageable with and drivable by driving surfaces (181a and 182a, respectively) of the 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 (183 and 184). The apparatus (102) further comprises an optical head (172) for writing and/or reading information on/from the optical tape (140) via the optical window (118). The invention has the advantage that it provides a system for recording and/or reproducing information which is very compact and which comprises a small number of movable parts.
