Sony announces 185TB magnetic tape

There is an interesting press release on Sony’s site, announcing that they have developed a new nano-grained magnetic layer for magnetic tapes. The big story here is that this new technology has shown to allow a staggering recording density of 148 gigabits per square inch. That is some 74 times the density of current magnetic tape media. A tape cartridge using this technology would be able to hold the 185TB from the headline. That is amazing.
