A serialaccess memory offering very dense storage. Bits are stored as tiny, movable magnetic domains that are circulated through a thin film of magnetic garnet crystal fabricated similar to an IC. Packaging is similar to a DIP.
Rugged, solid state magnetic storage device that holds data without power. Globular shaped bubbles (bits) are produced electro-mechanically in circular strings inside a thin-film magnetic recording layer; to read or write the bubbles, they are rotated past a read/write head.
A solid-state NON-VOLATILE RAM device. Bubble memories store data in the form of cylindrical magnetic domains, or bubbles, in a thin film of magnetic material on base, such as a garnet wafer. Bubbles are created from electrical signals by a bubble generator within the memory and reconverted to electrical signals by an internal detector. Unlike other non-volatile magnetic media forms, the memory domain does not wear out. [ 10:8] NOTE: Bubble memories possess the following desirable characteristics: (1) Wide operating temperatures; (2) resistance to mechanical shock and vibration; (3) data retention and reliability; (4) immunity to strong magnetic fields and electrostatic discharge; (5) inherent radiation hardness; (6) immunity to dust and chemical pollutants; and (7) secure instant erasure with a single write-over operation.

A relatively new type of computer memory; it uses tiny magnetic "pockets" or "bubbles" to store data.
A type of solid state memory device, which uses the magnetic properties of single crystals. Bubble memory is capable of storing very large amounts of data in a very small space. Access time is also very short.
High density memory utilizing microscopic magnetic domains in an aluminum garnet substrate.
A non-volatile memory device which stores numeric information safely even when power is withdrawn. Information is stored as magnetic 'bubbles' on a sliver of synthetic garnet. Microscopic in size, the bubbles follow a path through a circuit and when stopped provide a pattern of 1 and 0 information which is a permanent memory. Expensive but excellent.
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, which each store one bit of data. Bubble memory started out as a promising technology in the 1970s, but failed commercially as hard disk prices fell rapidly in the 1980s.
