DVD Error Correction Tests
In the following tests, we examine the DVD reading capabilities of the drive with scratched / defective DVD media. For the tests we used CDVD Benchmark and Nero CDSpeed. The reference test media comes from ALMEDIO.
- Single Layer media
This is a single sided, single layer DVD-ROM with 4.7GB capacity, and its surface has an artificial scratch of dimensions varying from 0.4 to 3.0 mm.
The following transfer rate picture comes from the CDVD Benchmark v1.21 transfer rate test.
The scratched area did not affect the reading process and no errors were produced despite the high reading speed, which reached 16X towards the end of the test.
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.
Once again, the defective area did not affect the reading process.
- Dual Layer media
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.
The disc is a single sided, dual layer DVD-ROM disc with a capacity of 8.5GB. The only difference between the TDR-845 and the TDR-841 is that the first 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 micrometers.
Fantastic performance from the LG. The GSA-4163B carries on the reputation of LG burners with DVD error correction.
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 is designed for inspection and adjustment of DVD-VIDEO players. The disc checks the layer switch operation from layer 0 to layer 1 and also includes test pictures and test signals for DVD sound files.
The current TDV-541 also checks the error correcting capabilities of the drive and includes scratches from 0.4 to 3.0 mm.
Although this test media is difficult for many drives, the LG read it without any problems.
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 disc's surface, sized from 0.4 to 1.0 mm. It also has 65 - 75 micrometer thickness, fingerprints.
Absolutely smooth curve, indicating good performance for this particular test. The LG GSA-4163B has great DVD error correction capabilities.
