Disclosed is a tape drive system which can wind magnetic tapes in proper alignment and which minimizes the possibility of tape impressions on magnetic tapes even if the core of the take-up reel has step heights on its peripheral surface. The tape drive system includes a tape-shaped recording medium having a head edge where a leader tape is formed to prevent tape impressions from being formed on the tape-shaped recording medium itself; a plurality of grooves formed on a flange of the take-up reel or the supply reel, the grooves for directing an airflow to an outside of the flange upon winding of the tape-shaped recording medium; and the leader tape having a surface of a center line average roughness ranging from 10 nm to 60 nm and a total thickness ranging from 10 mum to 40 mum while being wounded around or the take-up reel.
