Arab News reported that a university technology student developed a new technique named Rainbow to store data on ordinary paper. According to Sainul Abideen, the student who invented the system, this method allows to store up to 450 GB on a piece of paper.
The Rainbow method uses geometric shapes instead of ones and zeros, such as squares and hexagons to represent data patterns. Color is also used in the system to represent other data elements.
Like CD and DVD discs, a piece of hardware is necessary to read data from the support, and the good news is that a plain scanner is sufficient. A dedicated software then translates pictures into digital data.
Using a plastic sheet instead of paper can improve durability over time.
As always, feel free to discuss this argument in our forum 🙂
