ABSTRACT:
A servo shield used in small Winchester drives is provided to minimize undesired crosstalk between a data read/write head used in a stack of hard disks and servo information that is provided on an adjacent disk. In the present invention, one surface of a middle disk is provided with servo information which is used to make certain that the head drive assembly, or actuator, positions the heads above the center of the data track regardless of thermal effects or other factors that might introduce errors. In order to avoid crosstalk between the data head and the adjacent servo head reading the servo information, a servo shield formed of a suitable material, preferably berylium copper, is positioned between the servo head and its adjacent corresponding read/write head. This servo shield is mounted interiorly of the housing and slides between the servo head and adjacent read/write head when the housing is finally assembled.
