When a disc is loaded in or unloaded from a disc device, even if the disc is pushed in the direction opposite to the transmission direction by external force to return or is pulled to return, it is possible to prevent the mechanism that transmits the disc from being damaged and to improve the reliability of the disc device. The assembly method utilizes two or more bonders. In some embodiments, this feedback takes the form of a submission of a response to a question or statement pertaining to a criterion for the item.
