In the following tests, we checked the DVD reading capabilities of the SAMSUNG
SE-W164C drive with scratched / defective DVD media.
For our tests, we couldn't use the CDVD Benchmark as we do normally, since it
was unable to recognize the drive, so we used only Nero CDSpeed . The reference
test media comes from ALMEDIO.
- Single Layer media
This is a single sided, single layer DVD-ROM with a 4.7GB capacity, and its surface has an artificial scratch varying in dimensions from 0.4 to 3.0 mm.
The following transfer rate picture comes from Nero CDSpeed.
A bit of a hiccup at the start with regard to the speed but no errors occurred.
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, the only difference being that there are no scratches on it. Instead, there are defective areas, ranging in dimensions from 0.5 to 1.1 mm.
There are also fingerprints sized between 65 and 75 micrometers.
A much smoother reading graph and again, the procedure finished successfully
without any errors.
- Dual Layer media
This is an 8.5GB dual layer single sided DVD-ROM disc with artificial scratches ranging dimensionally from 0.4 to 3.0mm, on both layers.
Scratches sized from 0.4 to 3.0mm on both layers, did not pose a problem for
the SE-W164C drive.
The disc is a single sided, dual layer DVD-ROM disc of a 8.5GBcapacity. The only difference between the TDR-845 and the TDR-841 is that the former includes defective areas and fingerprints.
The dimensions of the defective areas range from 0.5 to 1.1 mm and the fingerprints are sized from 65 to 75 micro meters.
Again a reasonably smooth graph with a good reading speed.
The TDV-541 is a single sided, dual layer DVD-VIDEO disc, with a capacity
of 8.5GB. The disc is based on the TDV-540 series which was designed to inspect and adjust DVD-VIDEO players. The disc checks the layer switch operation
from layer 0 to layer 1 and also includes test pictures and test signals on
DVD sound files.
The current TDV-541 also checks the error correcting capabilities of
the drive. It also includes scratches from 0.4 to 3.0 mm.
Very good error correction capabilities so far, excellent layer switching
in this case and without any deviations in speed.
The TDV-545 disc is based on the TDV-540 series. It is a single sided, dual layer DVD-VIDEO disc with a capacity of 8.5GB. The TDV-545 includes artificial black dots on the data surface, sized from 0.4 to 1.0 mm. It has also 65 - 75 micro meter fingerprints.
Excellent reading from the Samsung drive. The artificially embedded dots and
fingerprints were not a problem for the drive's error correction mechanism.
The SAMSUNG SE-W164C has a very strong error correction mechanism and managed
to read all of our discs successfully, without errors being reported.
