Optical disc device and hybrid optical disc

Abstract

When it is determined that the disc loaded on a player is a hybrid next generation DVD, the DVD layer is reproduced with a red laser light. In parallel with this reproduction process, a process for notifying the presence of the HDDVD layer is performed. That is, determination is made on whether the notification timing defined in advance has been reached. If the notification timing has been reached, a control instruction is output from a controller to an AV processing circuit, and the image information including the image notifying the presence of the HDDVD layer is output from the AV processing circuit. Thus, the user may learn that the HDDVD layer can be reproduced.

1 - 9 . (canceled) 
   
   
       10 . An optical disc device capable of reproducing an optical disc with a plurality of recording layers corresponding to a laser light of different wavelengths, image information being recorded on each recording layer, the optical disc comprising:
 a determination processing section for determining whether a plurality of recording layers corresponding to the laser light of different wavelengths are arranged in a loaded disc;   a notifying processing section for notifying to a user that the plurality of recording layers corresponding to the laser light of different wavelengths are arranged when it is determined by the determining means; and   a change processing section for changing a recording layer to be reproduced from a recording layer corresponding to one wavelength to a recording layer corresponding to another wavelength according to an instruction input from the user, and   wherein   the notifying processing section monitors whether or not notification timing defined in advance has been reached, after starting an actual reproduction of image information of the recording layer, and outputs an image and/or a sound notifying that the recording layer corresponding to another wavelength is present other than the recording layer currently being reproduced when the notification timing is reached.   
   
   
       11 . A hybrid optical disc comprising:
 a plurality of recording layers corresponding to a laser light of different wavelengths, wherein   image information configuring a series of screens displayed continuously is recorded on each recording layer; and   the series of screens displayed by reproducing the image information recorded on at least one recording layer includes at least one screen in which a main image itself partially contains an image that notifies a presence of a recording layer corresponding to a different wavelength.
