PURPOSE:To ensure the highly efficient recording by dividing a discoid recording region in its radius direction, sorting the information source in the same number as the divided recording regions in accordance with the information quantity and recording the information at the outer circumferential side of the divided region in the order of more quantity of information. CONSTITUTION:The digital signal which decides a scanning region is delivered to an information recording system. The quantity of information is proportional to the scanning region, and therefore the information recording system discriminates the quantity of information by the digital signal. Thus a large quantity of information is recorded at the outer circumferential side 8 of a recording region 7; while a small quantity of information is recorded at the inner circumferential side 9. That is, if the information is more than the information quantity of an A4-size original, it is recorded at the side 8; while the information is recorded at theside 9 if it is equal to or smaller than the information of the A4-size original. At the same time, the information is recorded at the side 8 if it is equal to or more than the information quantity of an A3-size original; while the information is recorded at the side 9 if it is less than the information of the A3- size original respectively. |
