Memorex D² DVD±RW/DL Recorder - Page 4
In the following tests, we examine the DVD reading capabilities of the Memorex F16 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 Memorex F16 read the disc accurately and no read errors were reported. However, towards the end where there are no defects, the output resembles a sawtooth where the drive alternates between 6X and 14X speeds. Other than this, the performance reveals very good error correction capabilities with scratched, single layer DVD-ROM discs.
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.
Exactly the same phenomenon as in the previous test where reading was flawless over the defective regions and towards the end once again we see the sawtooth affect.- 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 smooth graph above reveals excellent error correction with DVD double layer media.
This test 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 discs is that the first includes defective areas and fingerprints. The dimensions of the defective areas ranges from 0.5 to 1.1 mm and the fingerprints are sized from 65 to 75 micrometers.
One more time the tranfer rate graph was very good. No errors reported.
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.
The Abex TDV-541 is a diificult test for most drives and the Memorex passed it without any difficulties.
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 also has 65 - 75 micrometer fingerprints.
This disc proved to be no problem for the drive.
The performance of the Memorex F16 with DVD defective media was very good.
