Information processing apparatus
 An information processing apparatus includes a main base and a drive base on which support frames are erected to face each other. A pair of parallel guide shafts are supported on the frames and extend in the radial direction of an optical disk. An optical head is supported by the guide shafts to be movable along the shafts. Insulating tape is wound around each end of the guide shaft to electrically insulate the head from the base, thereby preventing external noise from being transmitted to the head via the base. The drive base is further insulated from the main base by insulating seals interposed between the main base and the drive base and by insulating collars through which screws attach the drive base to the main base.
