HOW SEAMLESS LINK WORKS
The Seamless Link algorithm (Fig. 4), constantly monitors the writer buffer level. If the writer buffer level drops below a threshold value, the algorithm concludes that a BUR is imminent and stops the writing process in a controlled way. This means that the data stream from the buffer to the disc is halted, and allows the buffer to be filled up again.
The exact location where the writing stopped is stored in the drive’s internal memory. In the meantime, the buffer level is continuously monitored and as soon as the buffer is full again, the algorithm will let the drive seek to the location where the writing stopped. It then resumes the writing process as soon as the laser
is on the exact spot where the writing stopped. This type of writing eliminates the gap, which occurs between two individual writing operations during traditional writing. Hence the name Seamless Link.

SUMMARY |
Seamless Link offers excellent management of BUR incidents when writing CD discs in
In addition, Seamless Link gives end users greater confidence in running other applications during the CD writing process, AND freedom from the time and frustration of retries due to a buffer under run incident.
