Abstract :
An estimate of integrated signal-to-noise ratio (SNR) of the combination of the reader element with associated shunt-parallel resistance and magnetic medium through the interconnect, flexible printed circuit, and preamp is developed. A key result is the noise figure (NF) that relates the integrated input and output SNR of the system. Total common mode rejection or ground noise rejection is estimated.
