Abstract: A content storing system for allowing a storing apparatus, which has a limited size of storage capacity, to be effectively used to record content data. The content storing system includes a user terminal apparatus that records content data received from an external apparatus; and a server that is connected to the user terminal apparatus and that records the content data received from the external apparatus. The user terminal apparatus notifies the server that the content data has been recorded, and further issues, to the server, a delivery request for the content data that was recorded in a user storage apparatus. In response to the delivery request, the server determines, from the notification, that the content data has been recorded, and then the server transmits the requested content data to the user terminal apparatus.
