PROBLEM TO BE SOLVED: To suppress an increase in a data amount and to effectively use a transmission band and recording capacity by temporarily removing copy information multiplexed at every sector and generating a representative value. SOLUTION: Representative copy control information is generated within the prescribed range by a representative copy control information generator 29 by using copy information, separated from the data by a copy control information separator 30 in an interface part 23 to be converted into a transmission packet by a packeter 26. The packets of the representative copy control information and the input data are multiplexed by a copy control information multiplexer 25 to be sent onto a bus by a transmitter-receiver 24. The data inputted to the interface part 2 in a data recording/reproducing device 1 are separated to the packets of the representative copy control information and the data by a copy information separator 12. The copy information of the respective sectors are restored from the representative copy control information by a copy control information demultiplexer 13, and the copy information is added to respective sectors by a copy information multiplexer 15. |
