← ScienceWhich outcome reduces data storage on magnetic tape?
A)Increased magneto-crystalline anisotropy energy
B)Lower coercivity at operating temperature✓
C)Higher tape drive servo precision
D)Reduced read/write head gap width
💡 Explanation
Reduced coercivity increases the risk of unintentional bit flipping arising from thermal fluctuations; this is the superparamagnetic limit. The reduction is due to thermal energy overcoming the energy barrier, inhibiting magnetization, rather than alternatives relating to precision or alignment.
