underrun

When writing to a CD-R disc, the inability of the computer to keep up with the recording process. There are numerous causes. The data may be coming from a slow CD drive or another slow source. The CPU may have limited memory, have too many open applications, or the drivers may be out-of-date. See thermal recalibration and coaster.

Incidentally, Plextor is incorporating a technology licensed from Sanyo, dubbed BURN-proof, that pauses the recording process whenever it senses a buffer underrun. That should keep the relatively expensive -RW disks from turning into coasters.
But even with 2x CD-R drives I often recorded at 1x speed to be on the safe side and avoid bUffer underrun, so I am not obsessed by theoretical speed advantages.
Creative's latest CD-RW features new BURN-Proof technology, which curbs buffer underrun, or insufficient delivery of data to the drive from the PC.
All of the new veloCD burners offer bit-perfect music and data recording performance -- and thanks to the inclusion of Buffer Underrun Protection, veloCD models eliminate clicks, pops and coasters for perfect recordings every time -- even during multitasking operations.
A host computer must consistently provide data at a full 11.08 megabits per second during any recording to avoid buffer underrun errors.
The overhead associated with getting hundreds of files scattered round the source drive may slow down the direct CD recording process and may result in buffer underrun that destroys the disc.

Because of the relatively small size of the packets, the buffer underrun nightmares of the Disc-At-Once technology that kept you on the edge of your seat watching the progress of recording a 600-plus MB image file will be also eliminated.
It incorporates the new Burn-Proof technology, eliminating buffer underrun errors in fast-write modes.
The larger the buffer, the more data can be put in reserve and the less likely you are to run into the dreaded buffer underrun. These days, the minimum buffer is 512 KB, but 1 MB is more common.
The new drive utilizes a high performance, plug-and-play Adaptec AHA-2930C SCSI card for quick and easy installation and has a 4MB buffer, which prevents buffer underrun, even at 8X recording speed.
Stalling occurs when the play-out buffer underruns. To prevent this event, the buffer must be maintained within a safe range.
