Abstract
An apparatus and method for controlling electrostatic discharge in magnetic tape heads is, provided. This method includes using a conductive adhesive to electrically connect the substrate and closure of each read/write module as well as connect the read/write modules in the head. The conductive adhesive can be used as an adjunct or a replacement for adhesives used during the normal assembly process. The modules are then connected to ground. In one embodiment, the read modules are electrically tied to the write module, which is then connected to ground through a high resistance path.
