oday, 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.
