In a recording/reproducing apparatus capable of communicating with a data transmission site and the other apparatus through a network, a control unit controls the recording and reproducing of the information based on firmware. A receiving unit receives first information from the other apparatus through the network, the first information including a request of updating of the firmware. An output unit outputs second information to the data transmission site through the network in response to reception of the first information, the second information including a request of transmitting third information used for updating the firmware. A unit acquires the third information from data transmission site through the network to update the firmware.
