ABSTRACT:
A head assembly includes a suspension, a head slider having a magnetoresistive element mounted on a tip end of the suspension, and a pair of lead lines disposed on the suspension and having ends connected to the magnetoresistive element. The head assembly also has an easily breakable short circuit pattern disposed on the suspension and connecting said lead lines to each other. When the head assembly is handled by itself, because the lead lines are short-circuited by the short circuit pattern, a current produced due to an electrostatic charge buildup flows through the short circuit pattern and is prevented from flowing through the magnetoresistive element. After the head assembly is installed on an actuator arm, the short circuit pattern is broken, electrically disconnecting the lead lines from each other.
