DaTARIUS has a long and impressive history: it started as Koch in the 1980s, and the company was the second in Europe to replicate CDs. At that time, test equipment did not exist, so they built their own.

After developing the first quality control analyzer for the optical media industry, DaTARIUS has continued to set standards and design breakthrough solutions, all of which have led to success for many major replicators.

The DaTARIUS name was created in 2000, following the separation of Koch test equipment from the kdg media manufacturing group. Within three years, DaTARIUS acquired three major names in the inspection, testing and verification equipment market – CD Associates, the optical disc branch of Integral Vision, and the assets of aeco Ltd (formerly Aerosonic).
