MaximumPC hat einen schönen Überblick über die Geschichte der Speichermedien von der Lochkarte bis BlueRay-Disc, das da oben war genau meine Datasette.

Long before flash-based MP3 players and CDs ever existed, music buffs carried around their groovy tunes on compact cassette tapes. It was Philips who introduced the medium first to Europe in 1963 and then to the U.S. one year later initially as a means for portable dictation. Not until the audio quality of music players improved did cassettes become popular for listening to music, ushering in the era of boom boxes and parachute pants (thanks M.C. Hammer). But even before D.J. Jazzy Jeff and the Fresh Prince could be heard belting out "Parents Just Don't Understand," cassettes also scored a gig as an inexpensive storage medium for home PCs starting in the 1970s. A standard 90-minute cassette could store roughly 700KB of data per side, taking center stage on computers like the ZX Spectrum, Commodore 64, TRS-80, and others.
