High Capability Error Correction LSI for CD Player and CD Rom

While the Compact Disc (CD) players have been gradually spread, a higher- performance for the error correction capability has been required in order to protect reproduced audio signals against errors due to scratches, finger prints etc. on a disc. On the other hand, the CD player have been given attention as a data file system, which provides a lower cost, more capacity and reliability than a conventional data file such as floppy disc system and so on. In order to apply a CD player to such a data file system what is called "CD ROM", an improvement of the error correction capability is also required.
