Abstract

In a magnetic rigid-disk drive, information to and from the data surfaces is transferred by a system that consists of a read/write preamplifier, conductors and the read and write transducers. Printed-circuit conductors are now replacing the connection between the head and the read/write preamplifier that has conventionally been designed using twisted-pair wires. This paper provides a practical method of simulating the electrical behavior of these interconnects, and through comparisons with measurements, demonstrates the validity of the design procedure
