A tape or disk cartridge can be precisely located in the three planes by arranging three pins in a triangular support for the cartridge. The two leading pins are provided with alignment tabs. The third pin has a flat surface. The shape of the alignment tabs is such that the cartridge is pivoted downward for alignment in the X-plane. The tabs engage notches in the cartridge to establish the Y- and Z-planes. Fig. 1 is a side view showing the cartridge 1 being located over three pins. The top view of the pins is shown in Fig. 2. The rear pin 2 has a flat top surface while the front pins 3 and 4 include tabs 5 and 6, respectively, formed in the top section of the pins. The front surfaces of the tabs 5 and 6 are formed at a radius R from the pivot point 7 to accommodate notches in the cartridge 1. One notch is shown in Fig.
