    • An information reproducing/recording system has a reproducing apparatus which reproduces program information from a first recording medium, a recording/reproducing apparatus which records program information on a second recording medium or reproduces program information from the second recording medium, and a control apparatus which controls the reproducing apparatus and the recording/reproducing apparatus. The control apparatus acquires first management information for program information recorded on the first recording medium, and acquires second management information for program information recorded on the second recording medium. And then, the control apparatus compares the first management information and the second management information, and judges based on the result of comparison whether program information corresponding to the first management information has been recorded on the second recording medium. And if the program information corresponding to the first management information has been recorded on the second recording medium, the control apparatus judges whether a predetermined recording condition is satisfied, and if the recording condition is satisfied, controls the reproducing apparatus and the recording/reproducing apparatus so as to record the program information recorded on the first recording medium onto the second recording medium.
    • 信息再现/记录系统具有从第一记录介质再现节目信息的再现装置,在第二记录介质上记录节目信息或从第二记录介质再现节目信息的记录/再现装置,以及控制装置 再现装置和记录/再现装置。 控制装置获取第一记录媒体上记录的节目信息的管理信息,取得记录在第二记录介质上的节目信息的第二管理信息。 然后,控制装置比较第一管理信息和第二管理信息,并根据比较结果判断与第一管理信息相对应的节目信息是否已被记录在第二记录介质上。 并且,如果与第一管理信息相对应的节目信息已被记录在第二记录介质上,则控制装置判断是否满足预定的记录条件,并且如果满足记录条件,则控制再现装置和记录/再现装置 以将记录在第一记录介质上的节目信息记录到第二记录介质上。
