Abstract
A disk drive includes an anti-static plate held against a plastic jacket of a cartridge assembly for neutralizing the effect of a static electrical charge accumulated on the plastic jacket. The plate is particularly effective in connection with a magnetic interface in which aerodynamic forces must maintain a magnetic disk within the jacket in contact with a transducer. The plate includes an area that covers a substantial proportion of the jacket surface opposite to the side of the cartridge assembly through which the transducer extends.
