To realize a broadcast program recording reservation apparatus for providing a large number of users with a broadcast program recording reservation service at low cost by remarkably reducing required storage capacitance of a storage means thereby reducing capital investment.

The broadcast program recording reservation apparatus 1 records broadcast programs designated from user terminals 16a-19a and sends recorded data to a user terminal of a request source in response to a request from the user terminal. The broadcast program recording reservation apparatus 1 is provided with a storage and preservation means for storing and preserving the recorded data of the broadcast programs, and the storage and preservation means compresses, stores and preserves the recorded data which are designated from a plurality of users in the stored and preserved recorded data as a shared file to be shared among the users. Thus, the storage capacitance of the storage and preservation means is reduced as the number of shared files to be shared increases, the capital investment is reduced, and the recording reservation service is provided to a large number of users at low cost.
