The magnetic tape guiding system of a tape recorder transport system has a supply reel pole base assembly (235) having a slant pole (235) with a first guide unit (238) having portions formed at both ends of the slant pole (235) to function as a conventional roller for regulating upward and downward movement of the upper and lower edges of a moving magnetic tape (20), and a tension pole assembly (231) having a tension pole (233) with a second guide unit (234) having portions formed at both ends of the tension pole (233) to function as a conventional impedance roller for regulating upward and downward movement of the upper and lower edges of the moving magnetic tape (20). This arrangement can thus achieve 2-dimensional plane-traveling of the magnetic tape while also reducing the number of the parts of the guiding system <IMAGE>
