Real science: 1958 version of an IBM "hard disk"

IBM "350 Disk Storage Unit" with a capacity of 5MB, dimensions "60 inches long, 68 inches high and 29 inches deep", & contains "50 magnetic disks"!

Actually, its probably 6- or 7-bit bytes (to hold English alphanumeric characters) rather than modern 8-bit ones. About one MP3 song in a 5 feet by 5.5 feet by 2.5 feet unit weighting may be a few hundred kg.

Link includes a picture too.
