Abstract
Die Innovationsschübe der Computertechnik sind bedingt durch die Entwicklung von Halbleiterkomponenten mit immer höherer Rechengeschwindigkeit und Datenspeichern mit immer höherer Speicherkapazität. Die Steigerung der Speicherdichte auf mehrere Millionen Bytes pro Quadratzentimeter bei digitalen optischen Speichern ist allerdings mit einer deutlichen Abnahme der Haltbarkeit im Vergleich zu konventionellen Speichemedien wie Papier und Mikrofilm verbunden. Was sind die genauen Gründe, und wie steht es mit der Brauchbarkeit als Archivierungsmedium?
