Digital data storage on microfilm is a highly promising technology for migration-free long-term storage of digital information. The lifetime of the medium microfilm is estimated to be 500 years under appropriate storage conditions. Towards a practical implementation of this concept, the MILLENIUM project was initiated in 2006. The project is funded by the German Federal Ministry of Economics and Technology (BMWi) and is conducted by two research institutions as well as several small and medium-sized enterprises. This paper reflects project achievements with respect to signal and information processing. The complete processing chain for digital data is described. Important parts of this chain are identified and discussed in more detail. Some focus is on frame structures and data organization as well as synchronization, error correction and storage capacity. The developed concepts are ready for implementation.
