Abstract:
A magnetic head comprises a main pole, a return pole and a magnetic damper. The main pole is configured to emit flux and the return pole is configured to return the flux to the main pole. The magnetic damper is inductively coupled to the return pole and comprises a first conductor spaced from a first side of the return pole, a second conductor spaced from a second side of the return pole and a third conductor connecting the first conductor to the second conductor.
