Read/write head with dynamic flying height control by magnetostriction

摘要: A read/write head for use in a data storage device to control the low dynamic flying height order achieve high recording capacity of magnetic hard drives. The is designed that includes medium having surface. comprises pole tip region and an actuator. In turn, actuator excitation source generating field, magnetostrictive plate expanding response resulting protrusion section along direction towards surface, so flies above surface at lower than nominal height.
