Abstract:
A method for manufacturing a magnetic head with an electrostatic discharge resistor for preventing electrostatic discharge damage to magnetic head. The electrostatic discharge resistor is formed by a processes that saves manufacturing time and cost by forming resistor in the same deposition and patterning steps used to form the magnetoresistive sensor. However, the resistor includes only a portion of the layers used to form the magnetoresistive sensor, thereby ensuring that the resistor will have sufficient resistivity.
