To simplify incidental operations relating to setting of an earth plate for discharging static electricity of a disk drive for driving an optical disk, reduce the processing cost accompanying assembling of a bezel, and improve the versatility of the disk drive so that the bezel can be manufactured with a simple configuration at a low cost in order to set the bezel to the front end face of the disk drive through post-mount processing, and moreover to make it possible to supply a disk drive to unspecified users at a stable quality without lacking in specifications required to a disk tray for keeping a desired performance. In the case of a disk drive for loading or unloading a disk tray 1 to which a recording medium is set by moving the disk tray 1 forward or backward in a chassis case 10, an earth plate 9 for discharging static electricity generated at a bezel portion 8 is set so as to cover an essential portion of the front end face of the disk tray 1 at the disk tray 1 side. Moreover, in the case of a disk drive for loading or unloading a disk tray to which a recording medium D is set by moving the disk tray forward or backward in a chassis case, it is made possible to fix an inner bezel in which element components are mounted on the front end face of the disk tray and moreover integrate an outer bezel with the inner bezel by setting the outer bezel to the outside of the inner bezel.
