FlextraLink™ technology
The ASUS FlextraLink ™ technology provides a seamless combination of
flexibility and ultra-reliable recording quality.
FlextraLink ™ incorporates a flexible strategy that prevents buffer underrun
problems caused by an empty data buffer. This CD-RW drive technology
allows continuous monitoring of the data buffer status during the write
process. Once the available data drops to approximately 1% of the total
buffer capacity, the drive stops recording and marks the last write position.
When new data is received from the host, it is loaded to the data buffer,
and the laser is repositioned to link the new data with the data already
written. FlextraLink ™ uses minimal system resources so that your PC
remains fully operational throughout the writing process, and available for
other applications.
The diagram below shows the advantage of the FlextraLink ™ recording
technology.
