Morphology
The phrase is compositionally clear: a B1 learner who knows 'magnetic' and 'head' will understand this refers to a (usually small) head or component that is magnetic. However, the specific technical function of converting electrical signals into magnetic patterns for recording/retrieval is domain-specific and not fully predictable from the parts, so the expression is only partly transparent.
Etymology
Magnetic head: The name magnetic head comes from old tape recorders, where a small metal piece called the head touched the moving tape and used a magnet to 'write' sounds on the tape or 'read' them back. So today magnetic head means the part of a player or recorder that reads or writes information on magnetic tape.
