ABSTRACT:
An encoder demodulates an input signal of a program. Main data of the program are recorded in a recording medium as main information in the form of data blocks. Auxiliary information of the program are recorded in the recording medium as packs having a fixed length shorter than a length of the data block. A memory temporarily stores designated auxiliary information of a concerned program in connection with identification information of the recording medium in response to a recording of the main data into the recording medium. A controller causes the encoder to read all of the auxiliary information of the program stored in the memory at a time. The readout auxiliary information have same identification information corresponding to the same recording medium. The readout auxiliary information are modulated as packs and recorded in the subcode areas of the recording medium having the corresponding identification information.
