Physics Based Time Domain Simulation of Magnetic Recording Signal and Noise

摘要：

Progresses of a fast time domain simulator for magnetic recording signal and noise waveforms are reported. The simulator is a combination of recording physics calculation, micromagnetic simulation and experimental data information extraction. The simulator takes head media physics parameters as inputs and calibrates to measurements at current area density and scales to recording system at higher area density. It can generate millions of bits in short times, suitable for equalized signal to noise and channel bit error rate simulation. Key topics discussed in this paper to illustrate our techniques include: newly developed transition noise formula and its validation to micro-magnetic simulation, synthesizing time domain position-dependent transition jittering noise and colored electronic noise from measurement data, effects of non-saturation DC noise and head jittering on signal and noise waveforms.
