When playing back the track No. , Song name,
The playing time or the like is displayed, and a predetermined image (for example, an image showing that the CD is rotating) is displayed on the monitor device.

[0004]

By the way, when reproducing a content such as a CD without video as in the conventional case, the track number of the reproduced music is displayed on the monitor device. Since it only displays the song name, playing time, etc., or displays an image showing that the disc is playing, it does not necessarily function effectively for the user as an audiovisual system. . For example, if the user is C
If an image related to the artist of the song being played can be displayed on the monitor device when D is played, the user can enjoy it as a video clip when playing the CD. In this way, when trying to enjoy the video together while playing the CD, the video data suitable for the CD to be played is searched from the video data recorded on the hard disk, for example, and the CD is played and the video data is reproduced. I had no choice but to regenerate it.

Further, when reproducing a content without a video such as a CD owned by a user, if the related video is to be reproduced together, the video data related to the CD is recorded in advance in the recording device. It was troublesome because it had to be recorded.

In view of the above, it is an object of the present invention to provide a recording / reproducing apparatus capable of automatically reproducing an image related to music to be reproduced when reproducing a music content containing no image. .

Another object of the present invention is to provide a recording / reproducing apparatus capable of automatically acquiring and recording video data related to videoless contents owned by a user.
