The History of Data Tapes: From Round Reels to LTO and IBM 3592
Data storage has come a long way — but few technologies have shown the longevity, resilience, and cost-efficiency of magnetic tape. From the massive round reels of the 1940s to today’s compact, multi-terabyte LTO and IBM 3592 cartridges, tape has evolved into a technology that remains not only relevant but essential in the age of big data, AI, and compliance regulation. So why does a storage medium that predates the moon landing still dominate the world’s largest data centers? Let’s
