In conventional discs, two pieces of the same frame image information are recorded on one track, as shown in FIGS. 6 to 9.

In normal playback, half of the odd and even trunks are tracked as shown in Figure 6.7, and in still image playback, image information that is desired as a still image is tracked as shown in Figures 8 and 9. Only recorded tracks were repeatedly tracked.

[Problem that the invention seeks to solve]

Conventional video discs are recorded and played back in the manner described above, allowing for still image playback and normal playback, but normal playback requires only 1/2 of the information on the disc, and it is also possible to record stereoscopic images. It could not be played.

This invention was made to solve the above-mentioned problems, and provides a stereoscopic video recording disk and a stereoscopic video display device that can realize both stereoscopic video playback and normal 2D video playback with a single disc. The purpose is to obtain.

[Means for solving problems]

The stereoscopic video recording disc according to the present invention is for the right eye.

Image information for the left eye is recorded on odd and even tracks, respectively.

A stereoscopic image display device according to another aspect of the present invention uses a disk in which right eye and left eye image information are recorded on odd and even tracks, respectively, and in the case of stereoscopic image reproduction, the left eye image information is recorded on odd and even tracks. Tracks are played back alternately field by field, and right eye and left eye images are displayed alternately.
The image is viewed through each window, and in the case of normal playback, only one of the odd and even trunks of the left eye is tracked and reproduced to display only one of the right and left eye images, and the image is viewed through both windows. It is.

It is.

[Effect]

In this invention, the odd-numbered and even-numbered trunks of the disc as described above are tracked and played back alternately field by field, and the right-eye and left-eye images obtained at this time are used as right-eye and left-eye images, respectively.
By viewing with the left eye, it is possible to see a stereoscopic image, and by tracking and reproducing only one of the odd-numbered and even-numbered tracks with the left eye, it is also possible to see a normal two-dimensional image.
