Abstract
An imaging apparatus has a support shoe with an at-least-partially cylindrical inner surface for receiving a recording media, a rotor which is simultaneously rotatable about and linearly translated along a fixed axis, a write head assembly carried by the rotor to write on recording media received on the inner surface of the support shoe, a member having an arcuate outer periphery and supported within the support shoe for movement along the fixed axis, and electrically conductive bristles extending radially from the periphery of the member toward the received media to dissipate electrostatic charge build up on the media. The member is supported for movement with the rotor, and preferably leads the rotor as the rotor moves along the axis during a write operation. The bristles extend radially from the periphery of the member and are spaced from the received media to create an electrical stress in free air space. The bristles are attached to an electrically conductive strip that is attached by adhesive to the periphery of the member to lie flat against the periphery, and the bristles bend away from the member.
