Better yet, bubble memory devices needed no moving parts : the field that pushed the bubbles along the surface was generated electrically, whereas media like tape and disk drives required mechanical movement.

Bubble memory found uses in niche markets through the 1980s in systems needing to avoid the higher rates of mechanical failures of disk drives, and in systems operating in high vibration or harsh environments.

In old computers, magnetic storage was also used for primary storage in a form of magnetic drum, or core memory, core rope memory, thin film memory, twistor memory or bubble memory.

Another example is gadolinium gallium garnet, 3 2 ( GaO 4 ) 3 which is synthesized for use as a substrate for liquid-phase epitaxy of magnetic garnet films for bubble memory and magneto-optical applications.

It has a bubble memory option and various programming modules, including EPROM, and Intel 8048 and Pascal, and a set of tools for linking and statically locating programs to enable them to be burned into EPROMs and used in embedded systems.

"Bubble Memories " does very little to change the gameplay of the series, except for introducing giant enemies on some levels, different bosses, and a way to blow giant bubbles after charging up ( especially for killing the giant enemies ).

A selection of these early IBM design concepts created in the infancy of personal computing is highlighted in the book DELETE : A Design History of Computer Vapourware . One such concept in 1977, code-named Aquarius, was a working prototype utilizing advanced bubble memory cartridges.

Although it is known as a lower cost model, most notably removing its ( expensive ) bubble memory technology, the FM-7 was given a more advanced sound synthesizer, leading to a strong uptake among the hobbyist computer market in Japan and making it a more dominant system than the FM-8.
