Abstract

A helical scan magnetic-tape apparatus (1) including at least three tape guides (2, 25, 27, 28, 29, 30, 32, 33), including a magnetic-head unit (2). The apparatus (1) co-operates with a magnetic tape (8) wound on reels (9, 10) in a cassette (44). The tape-transport path in the apparatus includes at least three path sections (35, 36, 37) in which the tape (8) is twisted through a specific angle to correct for differences in level and inclination arising as a result of the helical path of the magnetic tape (8) around the magnetic-head unit (2).
