Hard Disk Drive Suspension Interconnect Modeling

摘要

As hard disk drive write and read data rates become higher, careful modeling of suspension interconnects becomes more important to understanding and designing the write and read circuits. In the past, interconnect models have often ignored losses and included only one propagation mode. More complete models that avoid these limitations are reviewed here and illustrated with example simulations. Fast-executing, reliable models can be chosen by considering the interconnect and terminating circuits of interest.
