Peak shift in high density recording in particle media

A single/double-density burst switching test pattern is used for the measurement of peak shift. Recording experiments with densities in the range of 1000 to 4000 flux reversals per millimeter have been carried out for oxide- and metal-particle media. The results are compared with linear superpositio...

Zusammenfassung:A single/double-density burst switching test pattern is used for the measurement of peak shift. Recording experiments with densities in the range of 1000 to 4000 flux reversals per millimeter have been carried out for oxide- and metal-particle media. The results are compared with linear superposition of isolated pulses. While at low densities the behavior is well approximated by linear superposition, the experiments unveil a rather uniform burst shift at higher densities. The effect of equalization is also shown.< >
