ABSTRACT:
Information may be erased from a magnetic tape with the tape being divided into at least two physical partitions. Each physical partition includes a plurality of data tracks carrying recorded data or the like and at least one set of servo tracks carrying position information dedicated to an area between the data tracks. At least one of the physical partitions may be erased during movement of the tape in a forward direction defined by moving the tape towards an end of tape designation, and at least a second of the physical partitions may be erased during the movement of the tape either in a backward direction defined by moving the tape towards the beginning of the tape or in the forward direction from the beginning of tape to the end of the tape.
