In addition to having the coolest-sounding name of these failed formats, bubble memory also was the most promising.
The format stored single bits of data in tiny circles, which allowed for denser data storage than traditional methods. Bubble memory boasted superior access time compared to disk or drum memory, and the bubbles were essentially immune to the normal wear that plagued other storage types.
But like every other entry on this list, the potential of bubble memory was wiped out by a faster-moving format — in this case, semiconductors and flash memory. The format didn’t even make it to the ’90s.
Though ultimately unsuccessful, bubble memory was a creative little piece of engineering.
