Data transmission system, data recording and reproducing app aratus and recording medium each having data structure of er ror correcting code

摘要

In a data transmission system for transmitting information data with a parity of an error correcting code for correcting an error in the information data, a read-out controller controls a transmitter to transmit the information data and the parity so that each data component of the information data obtained by dividing the information data of one data block area into a plurality of data components and each parity component of the parity obtained by dividing the parity of one block area into a plurality of parity components are transmitted at intervals of each sector having a sector address, wherein the sector is defined as a data area obtained by dividing one data block area of a predetermined data amount into a plurality of sectors each having an identical data amount.
