beskrivelse:

This image shows one "complete loop" of a magnetic bubble memory, consisting of a length of "track" from the orthomagnetic sheet and a minimum of associated drive electronics: At the leftmost end of the track, a pair of coils act as an electromagnet, "launching" new bubbles. These bubbles propagate along the guide pattern track, and wind up at the pair of coils at the opposite end. These coils act as a "pick-up", in which an electrical pulse is formed when a bubble arrives, and this pulse can be read off the output terminal at the lower right-hand corner. The same pulse is amplified and "signal conditioned" in the green amplifier triangle symbole in the middle.

During normal (read) operation, the switch to the left is set to lead the output from the amplifier circuit directly to the "bubble-launching" coils, thus re-creating the same series of bits as bubbles "running in circles".

When new information is to be written into the memory, the switch i set to direct pulses received at the input terminal at the far left, into the "launcher" coils, thus entering a new "string" of bits in the form of bubbles.
