The present invention relates to a recording apparatus for recording with a recording section including a feeding section for separately feeding recording paper sheet by sheet and a conveyance route extending substantially straight for conveying a recording medium having a high rigidity. The method includes positioning a sonic energy generator above the polishing surface of the polishing pad, and applying sonic energy to the polishing surface of the polishing pad. Additional isolated areas are formed remotely from the selected storage element by applying the isolation voltage to other remote storage elements. The finger extends through the first opening and directs the seal assembly as the seal assembly is advanced toward the second opening where a retaining member snap fits therethrough for retaining the weatherstrip to the body panel.
