摘要 |
A tension regulator for magnetic recording tape, which comprises a plurality of side members forming an encased columnar space having an open top for receiving a flexible tape loop. One of the side members is adjustably positionable relative to the other side member for changing the cross-sectional area of the columnar space in order to vary the tension applied to the flexible tape being received by the tension regulator.
