Abstract
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…
