← ScienceWhich outcome reduces hard drive storage density because of temperature increases?
A)Reduced magnetic domain alignment occurs✓
B)Increased sensitivity to external fields
C)Reduced probability of quantum tunneling
D)Increased coercivity field strength found
💡 Explanation
Temperature elevates the thermal energy of the ferromagnetic material. This disrupts the **Curie point transition**, where spontaneous magnetization diminishes because randomized atomic spin fluctuations counteract magnetic domain alignment; therefore storage density decreases, rather than density increasing from stronger coercivity.
