ABSTRACT:
A magnetic recording tape cartridge which includes partition walls protrusively provided, behind a central opening for insertion of a magnetic recording and reproducing head on the front side of upper and lower cases, said partition walls being extended at their both ends to positions behind the two openings for insertion of a pinch roller and an erasing head on both sides of the central opening, each of said partitions walls being so disposed as to couple at its front surface with the back of U-shaped guide walls provided protrusively on the case opposite to at least one of said openings, so as to ensure suppressing of the deformation of the case caused by warping and allow smooth running of the magnetic recording tape accommodated in the tape cartridge.
