Fanuc Bubble Memory Unit, Fanuc Memory Boards
Using a thin film of magnetic material, arranged in a series of parallel tracks which bubbles can move along, Bubble Memory is a non-volatile computer memory. Each bubble (or domain) can store one bit of data and is read by moving it to the edge of the material using a conventional magnetic pickup. During operation, bubble memories work in a similar way to delay line memory systems.
