METHOD OF HANDLING COMPOSITE RAW MATERIAL OF MAGNETO-OPTICAL DISK IN BANK DEVICE

PURPOSE:To enable the constitution of many kinds of commercial messages with a few raw materials by the composite raw material formed by combining the unit raw materials for the commercial messages in the case of recording the commercial message on a magneto-optical disk and reproducing and outputting thereof. CONSTITUTION:The raw material A as the main raw material 1 and, for example, 9 pieces of the raw materials B, C, D, ..., J as sub-raw materials are set as the sub-raw materials 2-1 to 2-9 in order to constitute each combination as one commercial message by the combination of the main raw material and the sub-raw materials to be combined therewith at 1:1. The contents of these combinations are assigned by data formats and many kinds of the commercial messages are constituted with fewer raw materials.
