High Speed Hard Disk Suspension Electric Design and Model Validation
In a hard disk drive for magnetic data storage, successful design of the front-end R/W channel is vital for achieving high density storage. Such a design involves both high track densities with resultant smaller signals and higher linear densities with signals occupying wider frequency bands. Current technical literature offers few works describing the design process, and there is no consensus as to choosing either time-domain characterization or the frequency-domain (S-parameters) modeling approach.
