The transmitting and receiving responses, as well as the admittance and impedance curves, are discussed for both electric and magnetic field transducers as a guide for evaluating measured results. A ...

whereas in HAMR the laser is constantly on and we modulate the high magnetic field near the optical spot. We fly a transducer just 15 nm above a recording medium at 2,700 r.p.m. In our case ...

2) Y = G + jB where G is the conductance and B is the susceptance. Antiresonance, f a 1) For an electric field transducer, the frequency at which the mass and open-circuit stiffness cancel or the ...
