In the fall of 1977, I experimented with a newfangled PC, a Radio Shack TRS-80. For data storage it used I kid you not a cassette tape player.
Tape had a long history with computing; I had used the IBM 2420 9-track tape system on IBM 360/370 mainframes to load software and to back-up data. Magnetic tape was common for storage in pre-personal computing days, but it had two main annoyances: it held tiny amounts of data, and
it was slower than a slug on a cold spring morning.
There had to be something better, for those of us excited about technology. And there
was: the floppy disk.

Welcome to the floppy disk family: 8, 5.25 and 3.5
