To allow using laser lights with different wavelengths, as required, according to an optical-recording medium to be used and notifying a user of various information about the optical-recording medium which is inserted. <??>A DVD drive 2 reads various information items that include a read-in area of an inserted DVD and that are provided on the inner-periphery side with respect to the read-in area, and it is determined whether the inserted DVD is for red data or a blue laser based on the information items. According to the determination result and the detection result, a system-control unit 18 of an information-processing unit 1 controls a video/audio-I/F unit 13 so that the determination result is displayed on an LCD 12. Where the inserted DVD is a red-laser DVD, the determination result is displayed by the color display corresponding to a red-wavelength region, and where the inserted DVD is a blue-laser DVD, the determination result is displayed by the color display corresponding to a blue-wavelength region. <IMAGE>
