- Researchers have created a DNA cassette tape that combines DNA storage with the look of 1980s cassette tapes.
- The DNA cassette stores digital information by encoding data in the sequence of DNA bases (A, T, C, G).
- Barcodes are used to assist with data retrieval, similar to finding a book in a library.
- The tape is coated with 'crystal armour' to protect DNA bonds, allowing data storage for centuries.
- 100 meters of DNA cassette tape can hold 36 petabytes of data, equivalent to 36,000 terabyte hard drives.
- The DNA cassette is incompatible with traditional cassette players as it uses DNA molecules instead of magnetic signals.
