Write once type information recording medium, method and apparatus for formatting the same, and method and apparatus for writing data to or reading data from the same

摘要

A write once type information recording medium having a recording format that includes sectors (500). Each sector includes x pieces of p-bit frames (510). Each frame contains an f-bit synchronization signal region (512) and a d-bit data region (514). Each bit of at least one x-bit packet (a, b, c, ..., n) in which a v-bit error correction code has been added to u-bit data, is distributed to each one of the data regions (514) of the x pieces of frames (510). 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.
