"More important is the Justlink technology on this writer to prevent those annoying buffer-underruns. Don't know what this is? Well, a buffer-underrun occurs when your system (and the buffer) can't provide data to the writer fast enough, even when the writer has a 2MB buffer like this MP7200A. This causes the writer to stop the burnprocess and makes your CD useless (this is called a coaster). Justlink prevents this buffer-underruns from happening. Justlink shouldn't affect the reading quality in the slightest way because it leaves an extremely short link (the patch between the data when the writer stops to let the buffer fill up again) of 2 µm or under. Isn't that great?!"
