ABSTRACT:
A computer media tape cartridge has a multiple volume selector switch with a plurality of positions which allow a user to physically segment the tape into a corresponding number of sections for more efficient use of the tape. By moving the switch to a desired position, the user may select and use the tracks in one or all of the positions on the tape. These positions include an "all position" wherein the tape is a single volume for reading and writing data, and individual positions wherein only the selected position is available for reading or writing data to the tape. Using the cartridge in the latter manner physically segments tape into four separate volumes. The cartridge is used in a tape drive having a plurality of sensors for detecting the position of the switch.
