Patent ID: 8824077

Claim:
A head carrier for a magnetic recording disk drive read/write head comprising: first and second electrically conductive terminals on the head carrier; a write head comprising an electrically conductive write coil on the head carrier; first ladder network compensation circuitry on the head carrier connected between the write coil and the first and second terminals and consisting of a first capacitor C 1 having a first end connected to one end of the write coil and a second end connected to the other end of the write coil; and second ladder network compensation circuitry on the head carrier connected between the first ladder network compensation circuitry and the first and second terminals and comprising a second capacitor C 2 having a first end connected to the first terminal and a second end connected to the second terminal, a first inductor connected between the first ends of C 1 and C 2 , and a second inductor connected between the second ends of C 1 and C 2 , wherein the first and second inductors have substantially the same inductance L 2 .
