ABSTRACT:
An apparatus for driving a tape-shaped optical recording medium, which comprises a supply reel (41) for supplying an optical tape (40), a take-up reel (42) for taking-up the optical tape (40), a friction capstan (43) for driving the optical tape (40) to run to the take-up reel (42) from the supply reel (41) and a running guide member (46) for guiding the optical tape (40) running between the supply reel (41) and the take-up reel (42). The running guide member (46) has a flat portion forming a guide face portion (70) for facing to the optical tape (40) is operative to cause the optical tape (40) to run along the flat portion. Thereby, an area on the guide face portion (70) of the running guide member (46) where an incident position on the optical tape (40) of a light beam is fixed invariably can be stably maintained to be relatively wide.
