1. An information reproducing apparatus for reproducing information from a recording medium, the recording medium comprising image data having a predetermined aspect ratio and identification data which indicates the aspect ratio of the image data,the apparatus comprising,a reading device which reads the identification data and the image data, the identification data being read prior to the image data;
- a first memory which stores the identification data;
a second memory which stores the image data;
a data separating circuit which supplies the identification data to the first memory and supplies the image data to the second memory;
an input device which enables a user to designate manually a manually designated aspect ratio of an image to be generated;
a controller which compares the manually designated aspect ratio and the identification data and generates a control signals; and
an image data processing circuit which generates video signal to be displayed with the manually designated aspect ration in accordance with the control signal.

Abstract
Image information is reproduced in respectively correspondence to monitors of different aspect ratios as in the NTSC system or HDTV system adaptive type. The image information recorded on a video disc is reproduced. An ID signal held in the video disc is detected. The aspect ratio of the image information to be generated is designated. Only when the aspect ratio indicated by the detected ID signal differs from the designated aspect ratio, the reproduced image information is converted into the image information of the designated aspect ratio. A standardized image signal is produced on the basis of the converted image information.

16. A method for recording and reproducing image information by means of a recording medium, which comprises:
-
recording image information on said recording medium together with identification data indicating a predetermined single aspect ratio; reading said image information and identification data from said recording medium; comparing the predetermined single aspect ratio of said identification data with a manually designated aspect ratio so as to determine a determined aspect ratio; and reproducing said image information with the determined aspect ratio.
