PURPOSE:To ensure the operation of sub-code generation, by receiving a marking signal incoming fastest only when the marking signal of a main code start section is inputted intermittently less than prescribed time, in the marking mode preceding each succeeding mode for the formation of the sub-code. CONSTITUTION:The sub-code generator is operated in response to marking mode, read mode, program save mode, program load mode and the like designated by a keyboard and the required sub-code is formed easily, surely and automatically. At the cutting mode, the main code is encoded by the sub-code and becomes a master disc recording signal. Further, the program check mode for the change of content is attained. When plural music head marking signals M. HEAD are inputted intermittently in the interval <=10sec at the main code start point being one unit of the VTR tape, the input incoming fastest only is accepted, allowing to ensure the operation of sub-code generation. |
