Which effect accelerates hard drive failure when sustained high temperatures influence read/write heads?

A)Curie temperature demagnetization
B)Capacitive read instability
C)Thermoelectric voltage reversal
D)Giant magnetoresistance damping

💡 Explanation

At the Curie temperature, thermal energy overcomes exchange interactions, resulting in permanent demagnetization which causes data loss because the magnetic domains disorder, weakening the recorded signals; therefore, it's not capacitive instability or the thermoelectric effect, rather than domain rearrangement.
