the efm decoder 37 the efm signal fed thereto is shaped by a wave shaping circuit 71 demodulated by an efm demodulator 72 temporarily stored in a ram 73 for example of 16 kbits and corrected by an error detecting and correcting circuit 74 after processing such as de interleaving or the like on the other hand in the data decoder 52 the digital data is temporarily stored in a ram 75 and corrected by an error detecting and correcting circuit 76 after processing such as de interleaving or the like by means of the control signal from the memory control circuit 63 if the ram 75 is made to have a capacity corresponding to an amount of two blocks that is about 38 kbits it is possible to store picture data for one screen at the same time the capacity of the ram 75 may be selected to be an amount of one block that is about 19 kbits as described above the present invention can provide a video disk in which a television picture signal and a digital data signal are recorded on one track with frequency division multiplexing the digital data signal is divided into blocks each composed of a predetermined number of bits a terminal part in each of the blocks is recorded in the vicinity of a position corresponding to a.
