Im Laufe der Zeit wurden die Bandlängen und Kapazität des DDS-Formats immer wieder erhöht. Die Formate DDS, DDS-DC, DDS-2, DDS-3 und DDS-4 sind in den folgenden [[Ecma|ECMA]]- und [[International Organization for Standardization|ISO]]/[[International Electrotechnical Commission|IEC]]-Normen spezifiziert:
* ECMA-139 (1990)], ISO/IEC 10777: 3,81 mm Wide Magnetic Tape Cartridge for Information Interchange – Helical Scan Recording – DDS format<ref>[http://www.ecma-international.org/publications/standards/Ecma-139.htm ECMA-139 (1990)], ISO/IEC 10777</ref>
* ECMA-150 (1991)], ISO/IEC 11557: 3,81 mm Wide Magnetic Tape Cartridge for Information Interchange – Helical Scan Recording – DDS-DC Format using 60 m and 90 m Length Tapes, 2nd Edition<ref>[http://www.ecma-international.org/publications/standards/Ecma-150.htm ECMA-150 (1991)], ISO/IEC 11557</ref>

Die verschiedenen DDS-Formate sind begrenzt [[Abwärtskompatibilität|abwärtskompatibel]] – in der Regel kann auch die Vorgängergeneration verwendet werden, manchmal auch noch die davor, ggf. aber nur lesend.<ref>{{cite web|url=http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-lpg50457 |title=HP StorageWorks DDS/DAT Media - DDS/DAT Media Compatibility Matrix |publisher=Hewlett Packard Enterprise |date=2016 |accessdate=2017-04-13}}</ref>
