ABSTRACT:
The present invention is directed to a magnetic recording tape cartridge having a tape chamber for containing a recording tape, the intermediate portion of the recording tape being adapted to advance along a predetermined path defined along a plurality of openings defined in the front wall of the chamber. A magnetic shielding plate and pad device composed of a resilient plate are positioned in the tape chamber disposed to face one of the openings to which a recording tape head of a tape player is inserted and a pair of stepped ribs are provided extending in a backward direction from positions near the front wall with such a height that portions of the ribs are closely opposed to the bottom edge of the plate of the pad device so that the pad device is held in the required position. The ribs are further designed to support the level of the recording tape and secure the positioning of the shielding plate.
