The 2352 sector is the entire sector size. However a normal data cd will only use 2048 for actual data. The remaining 304 is used for sub-channel data and error correction bits. If you ever check a full videocd that uses the full 2352 sector for data then you will see that it shows it as having approximately 800MB on it instead of the 700MB that the disc is advertised to hold. A friend of mine didn't believe me until I brought in a disc I made and showed it to him.
