Abstract:
Today, magnetic tape is the lowest cost technology for storing large volumes of digital data. Historically, areal density scaling has been the main driver of the exponential decrease in cost, i.e. $/TB of capacity, of both tape and hard disk drives. Recently, HDD scaling has stagnated while tape continues to scale at historical rates. The INSIC 2024-2034 Tape Technology Roadmap projects that tape areal density will scale with a 32% compound annual growth rate enabling an approximate doubling of capacity every two and a half years until at least 2034, at which point tape systems are expected to reach an areal density of 315 Gb/in2. The feasibility of these projections have been validated by a recent research single channel tape areal density demonstrations. The scaling challenges and future roadmaps for tape and HDD will be discussed and contrasted with research into alternative archival storage technologies.

Dr. Mark Lantz is a Distinguished Research Scientist and manager of the Tape Research Group at IBM Research Europe - Zurich. He holds degrees in electrical engineering from the University of Alberta and a Ph.D. from the University of Cambridge (1997). With over 20 years of experience in storage technology, he has been an IBM Master Inventor since 2011, co-inventor on more than 200 patents, and co-author of over 130 publications. His research focuses on storage technology, computational storage, and system reliability. Dr. Lantz was named an IEEE Fellow in 2019 and has received multiple awards, including the IEEE CSS Control Systems Technology Award (2009) and the IFAC Industrial Achievement Award (2014).
The Zentralbibliothek Zurich, the CERN Scientific Information Service, and AILIS (Association of International Librarians and Information Specialists, Geneva) jointly organize the Library Science Talks. A programme of talks for 2025 can be found on the AILIS website.
