ABSTRACT:
The invention relates to a system comprising a magnetic tape (7) and a magnetic tape apparatus (1), which apparatus (1) comprises drive means for driving the magnetic tape (7) and reels (5,6), magnetic-head means (9, 10), and buffer means comprising a belt (8), the information on the magnetic tape (7) being arranged in sections (47) and being recorded in individual discontinuous tracks (48) within the sections (47), each section (47) having a magnetically recorded address (49). The system further comprises input means (51) for selecting one of the sections and a control unit (45) comprising a selection device (45a) for the rapid location of the section (47), and control means (45b) for controlling the tape transport within a section (47). As a result of this, the system is suitable for the storage of large amounts of information in serial form in such a way that the information within each section (47) can be scanned directly.
