Abstract:
1. A disk drive system comprising: a transceiver circuit comprising a write driver transmitter circuit and a receiver circuit; a write element for writing data patterns on a disk storage medium in response to a write signal generated by the write driver transmitter circuit; a first conductive interconnect connecting the write driver transmitter circuit to the write element, wherein the first conductive interconnect comprises a first characteristic impedance; and a second conductive interconnect connecting the write element to the receiver circuit, wherein a second conductive interconnect comprises a second characteristic impedance, wherein the write signal flows through the first conductive interconnect, the write element, and the second conductive interconnect to the receiver circuit, wherein the receiver circuit comprises at least one resistor that terminates the write signal, and wherein the at least one resistor matches both the first characteristic impedance of the first conductive interconnect and the second characteristic impedance of the second conductive interconnect.
