Successfully recording a CD requires a constant, uninterrupted stream of high-speed data. CD-recording software places the data to be written in a small area of memory called a buffer. The CD recorder can draw data from this buffer at a constant rate while the software reads files from the hard drive.
Mouse movement, network and Internet activity, virus scanners, screen savers, or anything else that requires the processor’s attention can interfere with keeping the buffer full of data. A buffer underrun occurs if the CD recorder empties the buffer before it has finished writing a track. Buffer underruns will ruin a disc, turning that shiny CD into a coaster. Most modern CD recorders and disc-burning programs support BurnProof and similar technologies that thwart buffer underruns. However, a smoothly running, optimized system and a few tips can help you burn discs quickly and with minimal errors.
Use good quality media (preferably recommended by the manufacturer of your CD burner). Other media might work, but inferior media can deteriorate faster and can result in more errors when the disc is read. Also, make sure you get media rated for the correct speed. You may be able to record a blank disc at a speed higher than its rated speed, but if you do you’re more likely to encounter errors and compatibility problems when reading the disc on other drives.
