ABSTRACT:
A plurality of removable volumes for magnetic tape units are used as array for the storage of data. First an array of removable volumes is mounted on the magnetic tape units. Then each removable volume of the array is accessed at equivalent logical locations for storage or retrieval of the data file. Responsive to access of the array, data for the data file is striped to the removable volumes of the array beginning at the equivalent location on each removable volume. Depending upon the striping format, null marks may be striped to the removable volumes receiving fewer data than other volumes. This maintains the equivalent logical location for the start of the next file.
