ABSTRACT:
In a magnetic tape cassette, closely spaced support pins for guiding and holding a magnetic recording tape in contact with a recording and reproducing head are provided with a V-shaped concave guide surface. The V-shaped guide surface of each support pin bends the tape along its transverse axis when the head is inserted into the cassette and the tape is pressed thereon, thereby aligning the center of the tape with the center of the guide surface so that the tape is always maintained in a predetermined position with respect to the magnetic head, at the same time increasing the stiffness of the tape portion between the pins. The pins at their rear face also support a spring plate having a pad to contact the tape.
