2. CD,DVD reading tests

<%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"%> CD - DVD Reading

For our CD transfer rate tests, we used the Nero CD-Speed utility and a set of data and audio CD-R/RW/ROM. The drive can read CD media at a maximum speed of 48X.

For each CDSpeed graph, you can click on the image to see the complete screenshot of the software, including the measuring results.

- US RW

The following CD Speed graph shows the reading performance with US-RW media. For all the CDSpeed graphs, you can click on the image to see the full CDspeed snapshot.

- AudioCD

In the CD Speed Advanced DAE quality test, the drive's average speed was 27,85X with a quality score of 100.

- 90/99 mins Audio disc

Both the 90min and the 99 min audio CDs gave a read error, as you can see in the screenshots above.

- DVD Format

Now let's have a look at how the drive performs with DVD media. This time, a set of SL and DL DVD media was used. The drive is capable of reading at 12X maximum speed for single layer DVD ROM and at 12X for dual layer DVD ROM media.

DVD-ROM SL media -

PTP DVD-ROM -

The two layers of a PTP DVD-ROM disc are read sequentially with the drive starting reading from the inner part of the disc, which is the beginning of each layer, progressing towards its outer range.

The sharp drop downs of the speed just before the end of the second layer area could be considered as an issue here as the disc had some hard times read it.

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 of 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 and progresses towards the inner part of the disc.
