ABSTRACT:
A new generation magnetic tape cartridge of the type having a leader block is provided along with a new generation leader block pin so as to prevent interlocking with respect to prior art leader blocks and leader block pins. The magnetic tape cartridge is a generally rectangular container which has four corners. One of the corners of the container is beveled and is provided with a well to receive the new generation leader block in a nested position. The new generation leader block has a notch which has top, bottom and middle portions. A cross section of the middle portion of the notch is smaller than the cross section of the bottom portion of the notch, and the cross section of the top portion of the notch is smaller than the cross section of the middle portion of the notch. The cross section of the bottom portion of the notch is defined by a circular arc of more than 180.degree. for receiving and capturing a new generation leader block pin. The top portion of the notch in the block is fashioned to confine the new generation leader block pin to a predetermined amount of lateral movement. The configurations of the notch of the new generation leader block and the new generation leader block pin are fashioned to prevent interlock with prior art reader blocks and leader block pins.
