← ScienceWhich limitation on data storage increases with temperature in ferromagnetic drives?
A)Superparamagnetic effect erases stored bits✓
B)Increased coercivity hinders write cycles
C)Reduced hysteresis loops corrupt nearby data
D)Magnetostriction causes head crash errors
💡 Explanation
Data loss occurs because thermal energy overcomes the energy barrier maintaining magnetization direction; this is the superparamagnetic effect, therefore data becomes unstable and random, rather than retaining its integrity as coercivity declines.
