Abstract
A recording/reproducing apparatus comprises a program data reading-out device, a classification information storage device, a program data storage device and a controlling device. The program data reading-out device reads out program data from a recording medium. The program data and identification information for identifying the program data are recorded on the medium. The classification information storage device previously holds classification information for classifying the program data in association with the identification information. In the program data storage device, the program data can be written in and read out. The controlling device collates, when receiving a program recording command, the identification information between the medium and the classification information storage device, classifies the program data into groups in accordance with the classification information corresponding to the program data, and controls operation for recording the program data on the program data storage device, while controlling operation of reproducing predetermined program data which belong to the selected group when receiving a program reproduction command.
