Your own link tells you!
The introduction of dramatically faster semiconductor memory chips pushed
bubble into the slow end of the scale, and equally dramatic improvements in
hard-drive capacity made it uncompetitive in price terms.[1] Bubble memory was
used for some time in the 1970s and 1980s in applications where its non-moving
nature was desirable for maintenance or shock-proofing reasons. The
introduction of flash storage and similar technologies rendered even this niche
uncompetitive, and bubble disappeared entirely by the late 1980s.
- masspro 3y agoThere was a Konami arcade cabinet that (tried to) use bubble memory! It was considered a failure. Also from Wikipedia[0]: > It was considerably more expensive than ROM chip-based boards and extremely sensitive to electromagnetic fields that could render the game unplayable. You can find the start-up sequence of these on YouTube. It’s pretty…idiosyncratic. It took forever because it had to physically warm the memory up. Though I guess taking forever is irrelevant if you are turning on a machine only once in the morning. In fact, the music in the ROM it plays while starting up was named “Morning Music”.

- nonrandomstring 3y agoAmazing. I never realised it got to commercial production, just that about 1985 it was heralded as the next amazing thing - with however many libraries of congress per fingernail etc.
- Dylan16807 3y ago> with however many libraries of congress per fingernail etc. That's a bold claim! I found a NASA document from 1976 that expected bubble memory to reach about a terabit per cubic meter by the year 2000. And then you need over a hundred terabits for a library of congress. https://core.ac.uk/download/pdf/42884743.pdf https://core.ac.uk/download/pdf/42884743.pdf
