ABSTRACT:
A magnetic disk drive includes a stack of magnetic disks with servo tracks on a surface of a disk which is intermediate the extremes of the stack. A servo head arm assembly has three magnetic read/write heads and a servo head thereon. A multipart magnetic shield between the magnetic read/write heads and the servo head prevents electrical interference between the data signals and the servo signals.
