No need to thread

Long before there were cassettes, RCA caused this thing to be built:

For 1960, this was the bee’s knees. Or something. But gradually, things went from small to smaller to actually invisible. (See that MP3 over there? I didn’t think so.)

    Definitely stereo, even on my crummy laptop speakers!

    I vaguely remember reading about recording on wire before magnetic tape was a thing; cannot imagine the sound quality of that was very good.

    Actually, it was pretty decent, mostly because the wire traveled at a brisk speed — typically 24 inches per second, while tape machines knocked out 15 in the studio, and the few home units of that era crawled along at 7½.

    What eventually killed wire was the difficulty of editing, coupled with the ease of tangling — and, if you got too close to the wire, the possible loss of fingers.
