Plextor at 4X:

Memorex at 4X:

Well there it is, both + and - scans, wanted to include ritek G04 4X DVD-R discs as well but the plextor fails at writing these.

According to these scans writing at 8X with RICOHJPNR01 media is not that bad, but TY media is worse. This is cat and dog and the race is very close!!!

Comments/suggestions welcomed.

I wish someone would explain why we sometimes see those spikes of errors at the end of discs written at 4x and read at 4x. since they’re CLV speeds, there should not be such a spike.

Most likely the disc quality is lower near the edge of the disc.

Or possibly some tracking issue? The spike often goes away when scanning at 2.4.
