【Detailed ways】

The method for displaying the guide image of the disc information in the disc device according to the present invention will be described in detail below with reference to the attached drawings.

First, the present invention is applicable to optical disc devices similar to DVD or various A/V devices other than this. Disc Type (Disc Type), Disc Reflection Ratio (Reflection Ratio) and Wobble Frequency (Wobble Frequency) in the device can be used to determine whether it is DVD-R, DVD+R, DVD-RW, or DVD+RW.

That is, as shown in FIG. 3 , the disc reflectivity and wobble frequency are detected separately. If the disc reflectivity and wobble frequency are lower than the preset standard reflectivity (Ref_RR) and standard wobble frequency (Ref_WF), it is DVD- If R is higher than both, it is DVD+RW; if the reflectivity is low and the wobble frequency is high, it is DVD-RW; if the reflectivity is high and the wobble frequency is low, it is DVD+R.

On the other hand, similar to the above, when discriminating the disc type, the microcomputer 13 operates and controls the menu image generating device 14, and sets the disc type (Disc Type) and the recording mode (Record Mode) determined according to the disc type. Mode), and user navigation information such as functions provided in the device, are quickly output and displayed through the screen of a similar externally connected device such as a TV, which is described in detail as follows.
