ダイカストシヤーシー。 In the aluminum die-cast chassis of the floppy disk drive, a spindle motor having a cylinder at the top for centering and driving the floppy disk, which protrudes from below to above through a through hole formed in the chassis, is positioned at the height. A height position reference surface is formed on the lower surface of the aluminum die-cast chassis for regulating and mounting the head carriage, and a height position for regulating and supporting the step motor for driving the head carriage and the guide shaft for guiding the head carriage, respectively. A floppy disk characterized in that each of the reference surfaces is formed only on the lower surface of the aluminum die-cast chassis, thereby making it possible to process all of the height position reference surfaces in just one processing step. Drive aluminum die-cast chassis.
