Abstract:
1. A recording method of recording data onto a recording medium whereby first data comprising video or audio data and second data to be reproduced in synchronization with the first data are divided into blocks of a predetermined amount of data, each block as a unit is subjected to error correction coding and formed into an encoded block, and each of the encoded blocks is recorded as a unit onto the recording medium, the recording method comprising the steps of: managing the first data corresponding to a predetermined playback time and the second data to be reproduced in synchronization with the first data as a first continuous unit; encoding the second data in the first continuous unit into an integer number of encoded blocks and arranging said integer number of encoded blocks of second data in said first continuous unit in a continuous sequence separated from said first data; and arranging the continuous sequence of encoded blocks of second data in the first continuous unit immediately following a boundary of an encoded block of said first data that appears at a leading end of the first continuous unit or first in the first continuous unit according to the synchronism requirements of said encoded blocks of said first data and said second data.
