← ScienceWhich risk increases when magnetic hard drive heads approach disk surface?
A)Data corruption from quantum tunneling✓
B)Increased thermal creep from humidity
C)Electromigration due to raised temperature
D)Reduced data density limitations approach
💡 Explanation
Data corruption increases due to uncontrolled electron flow via quantum tunneling because it allows electrons to pass through the insulating gap. Therefore, data can spontaneously change state, rather than thermal disturbance driving mechanism as heads get very close.
