a writing unit for writing the content stored in the memory unit on an external recording medium; an IC medium reader/writer for reading an IC medium and recording the number of copies that can be made of the content stored in the memory unit on the IC medium in association with an identifier of the content, wherein the IC medium is separate from the memory unit and the external recording medium; and a controller for determining whether an the identifier of the content stored in the memory unit is recorded on the IC medium when the content is copied to the external recording medium and, when it is determined that the identifier of the content is recorded on the IC medium, controlling the writing unit to write the content on the external recording medium in accordance with the number of copies that can be made recorded in association with the identifier of the content, as well as controlling the IC medium reader/writer to update the number of copies that can be made of the content. ### Claim 2 (depends on 1) The information processing apparatus according to claim 1, wherein the controller, when it is determined that the identifier of the content stored in the memory unit is not recorded on the IC medium, controls the writing unit to prohibit copying the content to the external recording medium. ### Claim 3 (depends on 1) The information processing apparatus according to claim 1, wherein the controller, when the IC medium reader/writer cannot read the IC medium, controls the writing unit to prohibit copying the content stored in the memory unit to the external recording medium. ### Claim 4 (depends on 1) The information processing apparatus according to claim 1, wherein the IC medium reader/writer records the number of copies that can be made of the content stored in the memory unit on the IC medium in association with a hash value of the content, and the controller calculates an hash value of the content stored in the memory unit when the content is copied to the external recording medium, determines whether the hash value calculated is recorded on the IC medium and, when it is determined that the hash value calculated is recorded on the IC medium, controls the writing unit to write the content on the external recording medium, as well as controlling the IC medium reader/writer to update the number of copies that can be made recorded in association with the hash value of the content and record an updated number on the IC medium. ### Claim 5 (depends on 4) The information processing apparatus according to claim 4, wherein the controller controls the writing unit to prohibit copying the content to the external recording medium when it is determined that the hash value calculated is not recorded on the IC medium.
