DVD reading tests

- Single Layer DVD-ROM (Click for CDSpeed results)

To check the reading performance of the Artec drive with single layer DVD-ROM, we used NeroCDSpeed and the 820A test disc from Abex.

Comparing the three drives, the TEAC has the fastest reading speeds and fastest seek times. The reading speeds for the Artec drive are marginally slower that those of the TEAC DV-W58G, while in the seek times it is the slowest. However, the results are quite satisfactory and the drive appears to be a comparatively fast reader with DVD-ROM media.

- Dual Layer PTP DVD-ROM (Click for CDSpeed results)

The two layers of a PTP DVD-ROM disc are read sequentially, with the drive starting the read process from the inner tracks on the disc, where lies the beginning of each layer and progresses outwards towards to the outer tracks for each layer. The tools for this test are Nero CDSpeed and the Abex 840 test disc.

As with DVD-ROM media, here too the Artec drive was the slowest reader in both reading speed and seek times. The final reading speed did not reach 8x, falling well short of the mark at 7.6x.

- Dual Layer OTP DVD-ROM

The first layer of an OTP dual layer DVD-ROM is read exactly the same way as the first layer of the PTP disc we tested previously. The difference here is the reading strategy of the second layer on the disc. The beginning of the second layer is located in the outer part of the disc, so the drive starts reading from the outer tracks inwards towards the inner tracks of the disc.

The resultant graph shows smooth, linear CAV reading without any unusual deviations, reaching a final speed of 7.54x. The seek times are quite good with a very fast 102ms for random seek.
