← ScienceWhich outcome limits hard drive areal density when magnetized?
A)Superparamagnetic effect causes data loss✓
B)Hysteresis loop reduces switching speed
C)Magnetostriction creates mechanical stress
D)Exchange bias creates domain pinning
💡 Explanation
The superparamagnetic effect limits hard drive density because thermal energy overcomes the magnetic anisotropy energy barrier, causing spontaneous randomization of bits and therefore data loss, rather than stable magnetic domains needed for storing data.
