Abstract
A magnetic recording head system is protected against electrostatic discharge (ESD) and electrical overstress (EOS). The system includes a transducing read element and a drive circuit for connection to operate the transducing read element. A microelectromechanical switch has an input to receive an electrical control signal that selectively switches between a first state for protecting the transducing read element and a second state for operating the transducing read element.
