1) Update your Nero 7 version

2) Try a different brand/kind of discs

3) Update the firmware of your recorder

This steps should solve the problem.

It could be that DMA mode as been turned off:
Right-click My Computer>Properties>Hardware>Device Manager
Go IDE ATA/ATAPI Controllers, select your burner, right click, select Properties/Advanced & make sure the Transfer Mode is DMA - not P10.

If you have other burning software installed it may be conflicting with Nero. Antivirus programs running during the burn process can also cause these errors. Disable all unnecessary programs while burning a cd, and either temporarily disable or put Nero program in trusted zone in your antivirus program. Also, try setting a lower write speed.
