Abstract
With the explosive growth of the global data volume, traditional storage media have faced great challenge in satisfying the increasing storage requirement. Deoxyribonucleic acid (DNA) has become a new storage medium with great potential due to its ultra-high storage density and ultra-long storage durability. DNA may serve as the most suitable medium for digital archives of audio and video (AV) files because of its large storage volume and long durability. In this paper, we stored historical AV files to show the storage pottial of DNA media. We encoded two AV clips and a Chinese text with the overall volume larger than 3.0 MB into pooled 272340 oligos with a length of 169 nt. Simultaneously, we presented a hierarchical flexible access scheme integrating different synthesis pool, primers, data block and files. The proposed encoding and access method verifies the ultra-high density storage using synthetic pools.
