Claims: What is claimed is:

1. A tape transport including a capstan having a resilient outer surface, a first reel support including a first central indexing shaft mounted for movement toward and away from the capstan, a supply reel having a shaft portion received in the first reel support and positioned such that a magnetic tape pack on the supply reel can abut the capstan, a second reel support including a second central indexing shaft mounted for movement toward and away from the capstan, and a takeup reel having a shaft portion received in the second reel support and positioned such that a magnetic tape pack on the take-up reel can abut the capstan, said supply and take-up reels providing the entire support for the tape packs, characterized by bias means including a spring coupled to both the first and second central indexing shafts to apply the same force between the supply reel and capstan as is applied between the take-up reel and capstan, and brake means, positioned to apply a drag force to the supply reel during transfer of the tape from the supply reel to the take-up reel, with no component applying any force to the take-up reel during such tape transfer.

2. A tape transport as claimed in claim 1, and further comprising a base plate positioned to support the several transport components, a pair of indexing shafts supported beneath said base plate, and a pair of reel support carriages, each journalled on said indexing shafts for rectalinear sliding motion to accommodate movement of the first and second reel supports during operation of the tape transport.

3. A tape transport as claimed in claim 1, and in which said brake means includes a flexible member, biased into engagement with the first reel support on at least a portion of said support, to supply the drag force on the supply reel.
