What can the read/write head on a spinning disk be likened to?

The read/write head on a spinning disk can be likened to a record player arm because both are designed to access information stored in a specific format. The record player arm, or tonearm, moves across the surface of a vinyl record to read the grooves that contain audio information. Similarly, the read/write head moves over the magnetic surface of a hard disk to read or write data. In both systems, precision in movement is essential for accurate playback or data retrieval. This analogy reflects the mechanical operation of both devices, highlighting their functions in accessing stored information.
