magnetic bubble memory


Show Summary Details

Quick Reference

A type of digital memory in which data is represented by magnetic bubbles that are made to move through a stationary planar medium by applying suitable magnetic fields; the bubbles are tiny circular areas (stable magnetic domains) in which the medium is magnetized in the reverse direction to the rest of the medium.

Developed at Bell Telephone Laboratories in the 1970s, it failed commercially and is now obsolete.
