Morphology

magnetic + bubble + memory

The elements 'magnetic' and 'memory' transparently signal a type of data storage that uses magnetism, so learners get a general clue. However, 'bubble' here is a technical metaphor (tiny magnetized regions) unlike the everyday sense of a gas pocket, so the specific mechanism and meaning are not fully predictable from the constituents alone.

Etymology

Magnetic bubble memory comes from how the device works: it stores information as tiny round magnetic areas called 'bubbles' on a thin layer of magnetic material. So the name joins magnetic, meaning using magnets, bubble, meaning the small round areas, and memory, meaning 'data storage', which explains why the term means a device that keeps information in tiny magnetic 'bubbles'.
