Sony Crams 3,700 Blu-Rays' Worth of Storage in a Single Cassette Tape
Stupid hipster 80s fetishism notwithstanding, cassette tapes don't get much love. That's a shame, because magnetic tape is still a surprisingly robust way to back up data. Especially now: Sony just unveiled tape that holds a whopping 148 GB per square inch, meaning a cassette could hold 185 TB of data. Prepare for the mixtape to end all mixtapes.
