Using QScan
:
Imortance of TE & FE.
1. A good quality disc will have a clear track so a drive can write data more easily. Correctly focused laser makes a clearly defined pit. Hence , low TE/FE errorcan increase the writing quality of the drive.
2.If burning at low speed. A drive servo has the opportunity to compensate small TE/FE/variance of the disc.However at the increased speeds of todays drive. TE/FE plays an important part in assessing if the disc can be burned at the desired speed successfully.
As burning quality is a combination of drive & media. Having got a decent drive, plus DVD media coming in a variety of brands/printings. QScan will attempt to show disc quality via a graphic description.
Scans results can differ between batches of media (even with the same MID) due to varying sources/storage/place in the production run & so on.
Scanning.
Five modes are available.
Normal - A single-layer DVD+R/-R (4.7GB) takes 10 minutes to scan, & +R/-R DL disc takes about double the time.
Full - A single-layer DVD+R/-R (4.7GB) takes 20 minutes to scan, & +R/-R DL disc takes about double the time.
Quick - A single-layer DVD+R/-R (4.7GB) takes 2 minutes to scan, & +R/-R DL disc takes about double the time.
Smart - Required scan time depends on disc speeds available. One speed available for single-layer takes 20 seconds, & +R/-R DL requires double the time.
Customised - Under customised mode you can select & end scanning LBA (Logical Block Address). Note the input limitation : -
Start Position Minimum=0
End Position (1) Maximum =22295103 (2.7GB SL)
Maximum = 4153823 (8.5GB DL)
(2) End position value must be at least 150000 greater than start position.
