Magnetic-tape cassette apparatus and magnetic-head unit for use in conjunction with such apparatus.

摘要

In a magnetic-tape cassette apparatus a magnetic head unit (3) comprises a magnetic head (4) which at one side comprises a head face (6) in which a head gap (7) terminates. On each side of the head face tape guides (9, 10) whose radius is smaller than that of the head face are arranged in such a way relative to the head face that the magnetic tape (8) locally contacts the tape guide. The tape guides each adjoin a height limiter at one end, the two height limiters (13, 14) being arranged in such a way relative to the magnetic head that the connecting line (16) between the height limiters is perfectly perpendicular to a plane through the head gap. Furthermore, the apparatus comprises control means for constantly keeping a lateral edge (15) of the magnetic tape in contact with the height limiters during tape transport.
