Abstract
A data cartridge includes a length of magnetic tape which is formed at each end with a first pattern of holes to enable identification of the end of the tape and a second pattern of holes located within the first pattern of holes and configured to provide a binary code to enable automatic identification of the cartridge type or tape type. The first pattern of holes is different at each end of the tape to further enable the automatic differentiation of one end of the tape from the other end.
