<p>Magnetic tape cartridge, made up of a box (6) with a cover (7) and inside which there is a tape-winding spool (8), which is fed from a tape-storing spool (15), the tape is guided from spool to spool by a series of free- rotating rollers (1) which lead the tape along the inner periphery of the cartridge, passing through an area where this tape is exposed to a recording head, characterized by the fact that the above-mentioned area of exposure is located in a side and coplanar protrusion of the cartridge, in coincidence with a cross aperture (12) provided at the front of this protrusion, that this cartridge comprises means allowing to detect, by means of an external device, the end of the tape; and that the movement of the tape from the storage spool to the winding spool is made by means of winding rollers (5, 11) which ensure its regular run through the area of exposure to the recording head, the help of a device (14) which acts as a brake for the storage spool as well as a tensioner for the tape, and the use of a clutch (9, 20) located on the tape-winding or collecting spool (8) and intended to prevent the tape from being taut while in operation.</p> |
