Abstract
Embodiments described herein generally relate to resistive shunt design in a read sensor for providing accurate measurements from an electronic lapping guide (ELG). More specifically, embodiments described herein relate to a transducer resistor shunt structure for low cost probing. A bleed resistor network for a read sensor may comprise one or more first resistors arranged in parallel with one another and a second resistor arranged in series with the one or more first resistors. The resistor arrangement may require a small physical area and reduce or prevent ELG measurement errors.
