DNA Storage Breakthrough: Every Song Ever Recorded Could Fit on a Cassette-Sized Tape

Quick Summary

• Researchers at the Southern university of Science and Technology in Guangdong,China,have created a new data storage medium called a “DNA cassette,” which combines synthetic DNA molecules printed onto plastic tape with a design inspired by 1980s cassette tapes.
• The DNA sequence is designed to encode digital information similarly to binary code used in computers (A, T, C, G representing 0s and 1s). This allows storage of any type of digital file – text, image, audio, or video.
• To address accessibility issues in previous DNA data storage methods, the team incorporated barcodes on the tape for easier retrieval of specific data segments. The system follows an analogy akin to locating books in a library.
• The tape is coated with “crystal armour” made of zeolitic imidazolate to protect DNA bonds from degradation over time. It can preserve stored data for centuries.
• A traditional music cassette could hold about 12 songs per side; though, the new DNA cassette (100 metres long) can store more than 3 billion songs (36 petabytes total), equivalent to 36,000 terabyte hard drives.
• Despite resembling classic audio tapes visually and physically, these are incompatible with analog devices like walkmans due to fundamental differences; they carry non-magnetic DNA molecules rather than magnetic signals.
