magnetic bubble memory

computer science

Quick Summary

Magnetic bubble memory is a type of computer memory that stores information using tiny, movable magnetized cylindrical volumes called magnetic bubbles. These bubbles, which can represent a bit of information, are stored within a thin magnetic material. Developed in the late 1970s, magnetic bubble memory is more economical and compact than mechanical storage devices like tape, disk, or drum units. The memory consists of a chip, often made of synthetic garnet, where data is stored as these bubbles. The presence or absence of bubbles represents binary information (0s and 1s), similar to how magnetic cores function. This technology allows for storing large amounts of data in a small space.123
