Abstract :
The intergranular coupling dependence of transition parameter and signal to noise ratio (SNR) of tilted media were investigated and compared to those of perpendicular media. Tilted media yield smaller transition parameter and higher SNR. A shift of SNR peak for tilted media was observed and discussed.
