PURPOSE:To simultaneously reproduce information without necessitating a buffer of a large capacity, by executing densely the information whose time required for an output is different from each other, to a disk, so that this information can be reproduced and outputted continuously. CONSTITUTION:By folding like a bit train arrayed on one straight line of a spiral shape of a disk such as a CD, etc., a parallel sub-track band is provided. With respect to such a sub-track band, a recording area which is larger than the quantity of unit offer information in the time base direction, and also, provided with a delimiter at an equal interval by the time by which the output time of a contained sound, etc., is determined so as to be plural times is provided. Also, it is placed and executes recording by considering a time distribution which depends on the advance direction of a track corresponding to the quality of each speciality information of the unit offer information. Accordingly, a recording arrangement as shown in the figure is obtained, the sound of A1 and the sound of A2 are connected continuously, and the movement of a read head is not accompanied, therefore, a break of the sound is not generated.
