PURPOSE:To avoid a misoperation of a user, by contriving the recording form of a program for a video disk containing the information to be processed with the same program on both sides A and B. CONSTITUTION:A program start code 12, a program data 13, a program continuation code 14 and the image information 11b are successively recorded on the side A of a video disk 11 at the outer circumference part and toward the inside. While the warning information 15, a continuation data 16 of program data, a program end code 17 and the image information 11d are recorded successively on the side B of the disk 11 at the outer circumference and toward the inside. At the same time, a start code 22, a data 23 and an end code 24 are recorded on the side A of a disk 21 along with the warning information 25 recorded on the side B respectively. When such disk 11 or 21 is reproduced, the warning information is reproduced if no start code 12 or 22 is introduced and no end code 24 or 14 is stored yet. As a result, a misoperation to reproduce the side B first can be avoided. |
