<p>A tape transport is disclosed having a capstan drive, a reel drive for a take-up spindle for the take-up reel, a slipping clutch in said reel drive, and a selectively engageable direct drive connection between the clutch plates of the clutch to provide a non-slipping connection in the reel drive for use in fast drive modes, the direct drive including gear teeth on both clutch plates forming gears, and a short circuit gear engageable with the gears on both clutch plates. Also included are supports and operating mechanism by which the capstan drive and direct drive are engaged and disengaged in sequence; said capstan drive being disengaged before said direct non-slipping connection in said reel drive is engaged, and said direct non-slipping connection in said reel drive being disengaged before said capstan drive is engaged, to prevent direct reel drive of the tape without disengagement of the capstan drive, and avoid tape breakage or mechanism jamming.</p> |
