Firstly let’s get it clear. This is a guide & not some scientific measuring tool to which you must adhere. Generally only use if unsure as to the media quality of the media you’re using. When this test is run. No account of the affect that SolidBurn & WOPC will make whilst media is being written to.
How : - By measuring TE/FE* signal on blank media, QScan is able to the disc quality. This is shown in the clear graphic display. It can also show the speed supported by the drive. This may exceed claimed speed (especially if OverSpeed is enabled).
*TE - Tracking Error. FE - Focus Error.
