Abstract
A magnetic recording tape cartridge having a top section and a bottom section, each assembled together by means of tapping screws to provide a tape chamber in which a pair of tape reels for winding a magnetic recording tape is contained with one of the tapping screws adapted to be engaged with a boss located on the central portion of the cartridge near the tape reel. The cartridge comprises a partition wall member situated between the tape reels and the boss located in the central portion so that scraps produced from the boss during tapping of the screw into the boss are prevented from entering onto the magnetic recording tape.
