And an optical regeneration method.

The DVDP (Digital Video Disk Player) is an optical playback device that digitally processes and reproduces data recorded on an optical disk, and provides high quality video and high quality sound as compared to a conventional video casette recorder (VCR). In addition, since the DVDP can play not only a DVD but also data recorded on a CD, various types of optical discs provide corresponding functions.

However, although the conventional DVDP provides various functions suitable for each type of optical disc, most users use only the functions (for example, current time setting and playback) that are familiar with using an analog player such as a VCR. Not only do not use other functions, but also does not recognize whether they provide such a problem occurs. This is because, among the various functions provided by the DVDP, functions that are unfamiliar to the user are hardly used under the bias that they are difficult. In addition, when loading data recorded on an optical disc, the conventional DVDP only displays a screen indicating that the disc is loading, so that the user feels bored while the disc is loaded.

An object of the present invention is to provide an optical reproducing apparatus and an optical reproducing method that enable a user to recognize and use a function provided for each type of optical disc, and to provide an additional explanation for eliminating boredom while the disc is being loaded.
