A disk device writes data in or reads data from a disk. The disk device includes a head. The head includes a reading element that reads data from the disk and a writing element that writes data in the disk. The reading element and the writing element are placed apart from each other. For example, the writing element is arranged nearer to the outer periphery of the disk than the reading element is. The disk device includes two stoppers that restrict the movement of the head. The stoppers are arranged such that, when the head moves over the disk, a specific area on the disk is accessible only to the reading element and not to the writing element. Thus, data can be read from the specific area but cannot be written in the specific area.
