Therefore the inaccuracies were dynamically compensated, giving therefore better overall output. It also allowed distortion-free stills, slow-motion, fast-motion (both ways), fast winding both ways (_much_ faster than others), immediate recognition of the position of the tape with great accuracy - you could insert any tape in any position (no need to rewind), enter desired time from start, press "go to" and you landed where you wanted.

They managed to do this with VHS too, but much later. And for the 
distortion free stills and forward/back, you needed 4 heads on VHS.
