An apparatus for adjusting tension of a magnetic tape includes a clutch roller, which rotates in contact with one side of the tape and has a friction torque of a predetermined amount, and a low friction roller, which rotates in close contact to the other side of the tape, between a supply reel for feeding the tape and a drum. Accordingly, the tape tension servo apparatus can be more simply constructed. A constant tape tension can be always maintained irrespective of the rotation variation of the supply reel and an amount of the remaining tape.
