Sony is rolling out a new digital tape format intended for large-scale backups that can hold a massive 148 gigabits per square inch. Increasing the data density of the tape will ultimately lead to tape cartridges with a capacity of 185TB. The format will be detailed on May 4 in conjunction with IBM. Using a new manufacturing process, the tape uses a magnetic particle size of 7.7nm, which allows for the data density which is nearly 74 times that of the LTO-6 tape format introduced in 2012.
Sony has plans to commercialize the tape format itself, as well as the manufacturing process. No timetable has been made available as of yet for either release, other than the briefing at the Intermag Europe 2014 magnetics conference in Germany.
