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. |
