@Hephaestic @waff @matrix banks still use magnetic tape, because by law they need to keep their records a certain amount of time.
you can buy tape readers new for like $200. ofc they range between that and $10000+ for enterprise shit
the tape itself is like $150 for 18TB, so like $7.5 per TB uncompressed.
and you can buy all of these things new.
and its not some "ancient" hardware that needs maintenance, they're electronics. when have you given "maintenance" to your dvd player, for example? at most you keep the tape in a dry, temperate place.
