ABSTRACT:
A highly compact and functional professional audio magnetic tape transport provides a simple, symmetrical tape path including a pair of reels positioned in side-by-side relationship, a pair of large, equal diameter rollers positioned in side-by-side relationship below the reels, a pair of buffer loop tape tension arms positioned between the rollers and reels to receive tape directly from the reels along a straight tape line and without any intervening guide, and a transducer assembly positioned in frictional engagement with the tape along the tape path between the rollers. A capstan drive system is coupled to energize one of the rollers as a capstan to control tape motion along the tape path while reel servo systems energize the reels to maintain the tension arms at nominal central positions of rotation. Variations in tape tension with reel pack diameter are minimized and made self-equalizing by orienting the nominal arm positions perpendicular to tape direction for intermediate reel pack diameters. By utilizing torque transducers to actively control tension arm torque in response to system operating conditions tape tension adjacent the capstan can be balanced on opposite sides thereof and tape-capstan slippage can be avoided without need for an easily damaged, hard to maintain resilient rubber coating on the capstan or an awkward, large wrap angle of tape about the capstan.
