IP Expo: Tape Summit IBM has revealed it is preparing a technology demonstration of a 125TB tape, and has revealed that LTO-6 tapes use shingling, with overlapped data tracks.In January 2010, IBM demonstrated a tape with 35TB of raw capacity. Apply LTO-6's 2.5:1 compression ratio to that and you get 87.5TB. This contrasted with the then-current LTO-5 tape's raw capacity of 1.5TB.The LTO consortium has a roadmap of two more formats: LTO-7 with 6.48TB raw capacity, and LTO-8 with 12.8TB. Assuming that the upcoming LTO format capacity doubling, IBM's 35TB tape, created with the help of Fujifilm, would fit between a conceivable LTO-9 with around
