ABSTRACT:
A write once type information recording medium having a recording format that includes sectors. Each Sector includes x pieces of p-bit frames. Each frame contains an f-bit synchronization signal region and a d-bit data region. Each bit of at least one x-bit packet in which a v-bit error correction code has been added to u-bit data, is distributed to each one of the data regions of the x pieces of frames. This makes it possible for the write once type information recording medium to have an increased data storage efficiency and an effective error correction capability for a burst error.
