Due to parity, DVD+R is supposedly the best format...
"Error correction is the most important part of media, because if it does
not work, then you've lost your data, even if there is nothing seriously
wrong with the disc...
The DVD-R specification states that for every 192 bits, 48 of them are not
protected under any scheme, 24 of them are protected by 24 bits of parity,
and the last 56 bits are protected by another 24 bits of parity. This
weird (to put it mildly) scheme allows you to easily scramble or lose 25%
of the data that is required to read your disk! This information is almost
more important than the actual data burned on the disc itself...
The DVD+R specification, however, states that for every 204 bits of
information, it is split into four blocks of 52 bits containing 1 (shared
among all blocks) sync bit to prevent misreading because of phase changes,
31 bits of data, and a 20 bit parity (that protects all 32 bits)."
