Bubble memory is a type of non-volatile computer memory that uses a thin film of a magnetic material to hold small magnetized areas, known as bubbles or domains, each storing one bit of data. Bubble memory started out as a promising technology in the 1970s, but failed commercially as hard disk performance and cost improvements in the 1980s overtook its advantages.

Famous quotes containing the words bubble and/or memory:
“If the bubble reputation can be obtained only at the cannon’s mouth, I am willing to go there for it, provided the cannon is empty.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“The memory loaded with mere bookwork is not the thing wanted—is, in fact, rather worse than useless—in the teacher of scientific subjects. It is absolutely essential that his mind should be full of knowledge and not of mere learning, and that what he knows should have been learned in the laboratory rather than in the library.”
—Thomas Henry Huxley (1825–95)
