Electrostatic discharge protection for magneto-resistive heads |
摘要 |
An electrostatic protection network is disclosed that may be employed in a disk drive having a magneto-resistive read element. The network comprises a ground; and an array that block a signal current flow between the read element and the ground while a signal voltage is below a predetermined value and conducts the signal current from the read element to the ground while the signal voltage is above the predetermined value. The array is formed of a N-channel and P-channel junction field effect transistors. Thus, electrostatic discharge events are dissipated through the network to diminish damage to the read element during an ESD event.
