magnetic coercivity

magnetic coercivity

The amount of energy required to alter the state of a magnet. The higher a magnetic disk's coercivity index, the more data it can store.

Tape media to date has had the magnetic coating somewhat thick (0.5[micro]m or more) compared to these dimensions combined with moderate magnetic coercivity which yields broad written transitions due to the generation of transitions curving into the depth of the magnetic coating and the demagnetizing effect of sizeable opposing magnetic regions.
