25. Final words

In the following tests, we examine the DVD reading capabilities of the drive with scratched / defective DVD media (error correction). For the tests, we used Nero DiscSpeed. The reference test media comes from ALMEDIO.

- Single Layer media

ABEX TDR-821

This is a single sided, single layer DVD-ROM with a 4.7GB capacity, and its surface has an artificial scratch of dimensions varying from 0.4 to 3.0 mm.

The reading process was completed successfully, although the drive slowed down in the beginning of the disc.

Read errors	No, slowdowns in the beginning	No	No

ABEX TDR-825

This is also a single sided, single layer DVD-ROM of 4.7GB capacity. The data structure of the disc is exactly the same as that of the TDR-821, with the difference that there are no scratches on it but instead, defective areas of dimensions ranging from 0.5 to 1.1 mm. There are also fingerprints sized between 65 and 75 micrometers.

No reading problems here.

- Dual Layer media

ABEX TDR-841

This is an 8.5GB dual layer, single sided DVD-ROM disc with artificial scratches of dimensions ranging from 0.4 to 3.0mm, on both layers.

Same as before, successful reading without any speed fluctuations or read errors.

ABEX TDR-845

Great reading here.
