. 7751 ll.8.1975 ABSTRACT: Transversely writing and reading video cassette recorder or a similar apparatus for recording and/or reproducing wide-band signals on/from magnetic tape, which apparatus is provided with a rotating head disc and a tape guide system with concave guide members for guiding the tape past the circular path of the heads in a local condition of concave curvature. In addition to the concave guide members the tape guide system at either side of the head disc cow- prises convex guide members with a radius of curvature which substantially equals that of the concave guide members. The concave guide members belong to a pressure piece which in the operating condition of the apparatus presses the locally concave part of the magnetic tape against the convex guide members. The convex guide members are preferably disposed at an axial distance from each other which is greater than the axial distance of the concave guide members and so that in 1- the operating position a gap is obtained between each convex guide member and the nearest one of the concave guide members, where the tape is completely clear of any parts of the machine.
