Embodiments of the present invention provide a grounded conductive layer
between the heater and the lower magnetoresistive (MR) shield in the
read/write head structure. The grounded conductive layer eliminates or at
least substantially prevents the accumulation of charges on the lower MR
shield as a result of the voltage supplied to the heater. In one
embodiment, a magnetic head comprises a plurality of read/write
components; a heater disposed near the plurality of read/write
components; and a grounded conductive layer disposed between the heater
and the plurality of read/write components.
