Abstract:
In an information recording apparatus, when it is determined to perform a copy process, a copy processor copies content data cached in a first storage section to an information recording medium as copy destination. A process-result sender sends, to a copy-count management server, a result of the copy process. A cached-data abandoning unit abandons the content data cached in the first storage section if information regarding an allowable number of copies on which the result of the copy process has been reflected represents that a next copy process is disallowed.
