Abstract
A disc player that incorporates a single piece disc enclosure and a chassis section is described. The incorporation of the disc enclosure and the chassis section into a single piece eliminates the requirement for a separate damping system. As well as reducing the cost of manufacturing the device this also allows for the tolerance between the spindle motor and the disc enclosure to be precisely controlled so enabling miniaturization of the disc player.
