Abstract
A system comprises an apparatus (20) and a cassette (1) adapted to cooperate with each other. The apparatus comprises a magnetic-head unit (32) with a magnetic head (38), further tape guides (42, 44) and projections (48, 52). The cassette comprises a magnetic tape (3) and a resilient element (100) with tape guides (101, 102). During cooperation of the apparatus with the cassette the tape guides (101, 102) are situated between the magnetic head (38) and the further tape guides (42, 44), and the tape guides (101, 102) are in contact with the projections (48, 52). This provides an additional guidance for the magnetic tape at the location of the magnetic-head unit, which improves the contact between the magnetic tape (3) and the magnetic head (38) and the further tape guides (42, 44).
