Mems-based ESD protection of magnetic recording heads

   
   

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.

Un sistema magnético de la cabeza de grabación se protege contra la descarga electrostática (ESD) y la sobrecarga eléctrica (FOE). El sistema incluye transducing leyó el elemento y un circuito de impulsión para que la conexión funcione transducing leyó el elemento. Un interruptor microelectromechanical tiene una entrada para recibir una señal de control eléctrica que cambia selectivamente entre un primer estado para proteger transducing leen el elemento y un segundo estado para funcionar transducing leyó el elemento.
