Abstract:
A disc drive storage system comprising:a disc having a disc surface; a write head configured to write to the disc surface, the write head having a first end and a second end; a signal source configured to provide a drive signal to the write head, the drive signal including a differential signal component and a common mode signal component; an electrical interconnect path coupled between the write head and the signal source, the electrical interconnect path providing a return path for the differential signal component and an open circuit for the common mode signal component; and a common mode termination network having a first node, a second node and a center tap, wherein the first node is electrically operably coupled to the first end of the write head, the second node is electrically operably coupled to the second end of the write head and the center tap is connected to ground thereby providing a return path for the common mode signal component.
