To record sounds, this strip ran underneath a sharp needle sensitive to sound vibrations. Therefore, whenever a sound was made, the vibrations resulted in the needled forming a unique pattern on the wax strip.

Why is magnetic tape still used for storage?

Often thought of as a relic of the past, magnetic tapes actually function as a viable, and even efficient and highly secure form of data backup. The biggest value of the magnetic tape is that it can store huge amounts of data in a relatively compact format—some tapes are capable of holding several terabytes of data.
