System comprising a player and/or recorder apparatus and a tape cassette, and the apparatus and a cassette suitable for use in such a system

A system comprising an apparatus and a cassette suitable for cooperation with the apparatus,

• which cassette comprises a magnetic tape with a coating on one side, and a housing having two parallel main walls and transverse walls including one front wall defining a magnetic-head opening, along which front wall the magnetic tape in the housing extends with its coating side facing the opening, which cassette further comprises a resilient element with two tape guides, which element is situated near the opening behind the magnetic tape in the cassette, which tape guides each comprise a guide surface guiding the magnetic tape during cooperation with the apparatus,
• which apparatus comprises a magnetic-head unit with a head face past which the magnetic tape is moved in its longitudinal direction during cooperation with the cassette, the magnetic tape coating being in contact with the head face,
• characterized in that the magnetic-head unit comprises two pairs of projections, one pair at each side of the head face, the projections of each pair spaced at a distance from one another which is at least equal to the width of the magnetic tape, the pairs being spaced from each other by a distance such that the projections are in contact with end portions of the cassette guide surfaces, whereby clearance is provided between the tape guides and the magnetic-head unit during cooperation with the apparatus.
