Abstract
A magnetic tape transport apparatus including a rotary drum having a plurality of magnetic heads and spaced-apart tape entry and tape exit points; a tape path forming device including two combinations each having one guide roller and one inclined pole disposed respectively at the tape entry and tape exit points of the drum, from which points the magnetic tape begins to contact with and to leave from the drum, respectively, thereby causing the magnetic tape to partially wrap around the cylindrical surface of the drum through a predetermined angular range and to form a magnetic tape transportation path nearby the drum; and an impedance roller disposed at a position between the guide roller and the inclined pole of at least one of the combinations in contact with the magnetic tape; the impedance roller together with one combination of guide roller and inclined pole being disposed close to one of the tape entry and tape exit points of the drum when the magnetic tape is wrapped around the drum and is transported along the magnetic tape transportation path by a tape moving device.
