Which outcome occurs when stray magnetic fields interfere with the read head of Hard Disk Drives?

💡 Explanation

When stray magnetic fields interfere, magnetic domain orientation of written data is perturbed because the external fields superimpose upon the signal, leading to incorrect interpretation of bits during the read process. Therefore, spurious data readback results, rather than modifications in platter speed, head height, drive temperature, requiring thermal or mechanical changes.
