A configuration in which usage control that is substantially similar to content usage control in a copy source medium can be performed in a content copy destination is implemented. A data processing unit that performs a copy process of recording data recorded on a first medium on a second medium records encrypted content in the first medium on the second medium, without decrypting the encrypted content. In addition, the data processing unit converts a CPS unit key file recorded on the first medium to generate a converted CPS unit key file and records the converted CPS unit key file on the second medium. Further, the data processing unit acquires an MKB not requiring KCD, which is capable of directly calculating a media key using only a device key, without using key conversion data (KCD) recorded on the first medium, from a server and records the MKB not requiring KCD on the second medium.
