Abstract
Electrostatic discharge protection can be afforded to a data recording head in accordance with various embodiments. A data recording head may consist of a circuit having a preamp ground connected to a ground substrate via a ground trace. The ground trace can consist of a first leg connected to the ground substrate and a second leg with an open connection extending from a dice line.

An apparatus comprising a circuit comprising a preamp ground connected to a ground substrate via a ground trace, the ground trace comprising a first leg connected to the ground substrate and a second leg with an open connection extending from a dice line.
A system comprising a controller connected to a surface charge control circuit comprising a preamp ground connected to a ground substrate via a ground trace, the first ground trace comprising a first leg connected to the ground substrate and a second leg with an open connection extending from a dice line and terminating at an insulated location.
A method comprising:
- connecting a preamp ground of a circuit to a ground substrate via a ground trace, the first ground trace comprising first and second legs each separately connected to the ground substrate;
- and
- removing a portion of the ground substrate and second leg of the first ground trace along the dice line to terminate the second leg at an open connection extending from a dice line.
