A situation where some data is missing is to be prevented in a process of recording data on a second medium in a different format from the data recording format of a first medium. An information processing device that reads the data recorded on the first medium, and performs a process of recording data on the second medium receives copy permission information from a management server, and acquires, from a data providing server, additional data that cannot be acquired directly from the first medium. The information processing device reads a copy control management file recorded on the first medium, and accesses and acquires the additional data by using access information recorded in the copy control management file. The information processing device then uses data containing the acquired additional data as the data to be recorded on the second medium.
