Encoding Scheme to Enlarge Practical DNA Storage Capacity by Reducing Primer-Payload

Explore a technical conference presentation from SNIA SDC 2024 that delves into innovative approaches for expanding DNA storage capacity through advanced encoding schemes. Learn about the fundamental challenges of DNA-based data storage systems, focusing on how synthetic DNA sequences are used to encode and decode digital information. Understand the critical limitations of current random-access based DNA storage technologies, particularly the collision issues between primers and DNA payload sequences. Discover the newly proposed Collision Aware Code (CAC) encoding scheme, which achieves a remarkable 120% improvement in primer collision reduction and increases DNA tube capacity from 211.96 GB to 295.11 GB. Examine the comparative analysis of CAC's error recovery capabilities against existing encoding schemes, and gain insights into DNA storage background, practical capacity limitations, and innovative solutions for improving storage capacity. The presentation is delivered by researchers from the University of Texas at Dallas and the University of Minnesota, Twin Cities, offering expert perspectives on this cutting-edge storage technology.
