The floppy disk was a revolution in the computer industry when it was developed by IBM in the late 1960s as a reliable and inexpensive method of loading microcode into their System/370 computer.
Alan Shugart left IBM and moved to Memorex where his team shipped the Memorex 650 in 1972, the first commercially available read-write floppy disk drive. The 650 had a data capacity of 175 kB, with 50 tracks, 8 sectors per track, and 448 bytes per sector.
