The more we researched the topic, the more we found conflicting data on the coercivity of hard drive materials. One source said 1,250 Oe, another said 2,500 Oe. It seems that, in the race to make hard drives of greater storage capacities, hard drive manufacturers keep finding higher coercivity materials for the hard drive platters.
