We had those at my first programming job. At a later job in the 90s one of my minor duties was to swap out the tape cassette for daily backups. It held 8Gb and was about the size of a deck of playing cards. I remember talking with another guy about how amazing it was to put 8 gigabytes in your shirt pocket. Now that’s a fraction of a micro SD smaller than my fingernail.
They still use reel-to-reel tape drives on mainframes to store data. Just like they did in 1967.
