The traditional solution for buffer underrun was to enlarge the size of the buffer to allow it to accumulate more data. While this tactic helped reduce the frequency of underruns, once an error occurred, there was no way to save the address of the exact point where the underrun had occurred, so the user had no choice but to toss out the now-useless disc and try burning another.
Acer CM's Seamless Link is a breakthrough that allows the CD-RW drive to store the RecEnd address, the point in the data to which the recording mechanism has progressed, and pause the recording before a buffer underrun occurs. When the buffer is again full, a Seamless Link-enabled CD-RW drive locates the RecEnd address and resumes the recording process. The gap between the stop and restart point is closed, while managing the recording process precisely and transparently—eliminating underrun errors while maintaining recording accuracy. Seamless Link is also built in the latest Acer CD-ReWriter—the CRW1208A.
Seamless Link works its magic by following these steps:
