While a tray moves into a disk drive, a clamper and a turntable are used to clamp a disk. The first illumination apparatus is operatively associated with the computer-pointing device and generates light when the computer-pointing device is in a first operating mode. The objective lens housing is supported by upper and lower suspension springs. From the subtractive color image, adjacent pixels which are allocated to the same representative color are unified so as to extract an FCR candidate region. Upon completion of the first period, control circuit directs driver circuit to render upper transistor non-conductive and lower transistor conductive for a second period. With this arrangement, optimum reproduction can be performed for each medium in the super resolution medium.
