DNA Data Storage: A Decade of Coding and Decoding Progress

Explore a 31-minute conference presentation from the Storage Developer Conference 2022 examining the evolution of DNA data storage technology over the past decade. Dive into how DNA molecules serve as a revolutionary information storage medium, offering high spatial density and centuries-long stability at low energy costs. Learn about the key developments since Church's landmark publication, including challenges in data writing and reading processes, error handling specific to DNA storage, and the progression of coding algorithms. Understand various aspects of DNA data storage including bit-to-DNA base mapping schemes, data compression techniques, and error recovery strategies. Compare major mapping and error-correcting methods through a comprehensive feature analysis table that covers maximum data density, algorithm constraints like homopolymer and GC content, and both inner and outer Error Correction Codes (ECC). Presented by João Gervásio and Adriano Galindo Leal from Lenovo/IPT, gain insights into the historical development of DNA data storage ecosystem and the evolutionary progression of mapping and error-correcting methodologies.
