CD Recording Tests

- CD-R Writing Tests

The Philips JR4DVDRW supports 8x, 12x and 16x CAV writing speeds. Below you can see the CDSpeed writing simulation graph with Taiyo Yuden 48x CD-R media.

According to CDSpeed, the average writing speed with an 80min disc was 15.96x. The start and the finish speeds were 15.89x and 16.12x respectively.

- Recording Times

For the burning tests we created an 80min data compilation with Nero Burning Rom and recorded the data on a 700MB disc. In this test Philips was faster than Pioneer by over 2 minutes although both had the same recording speed.

Below are the best writing times for 8x, 12x, 16x using 48x CDR media from Taiyo Yuden.

In the next graph are the times for several media brands recorded at 16x with the Philips JR4DVDRW.

All the discs we tried needed approximately the same time.

- CD-RW Writing Tests

The Philips JR4DVDRW supports 10x maximum rewriting speed, with High Speed rewritable media. Below are the results from the CDSpeed writing simulation test with blank 10x HS-RW media from Maxell.

According to CDSpeed burning simulation, the drive started writng at 9.85x and finished at 9.74x with an average speed of 9.89x.

In comparison with Pioneer, Philips was slower by only 4 seconds which is a negligible difference.

- Packet Writing Tests

Using InCD and Mitsubishi Chemicals 24x US-RW media for all Packet Writing tests, quick format took 32sec. The formatted disc had 530mbs of free space. We copied a 403 MB file (412.822 Kb) from Hard Disk (on the same PC as the recorder) to the formatted RW media through Windows explorer (drag and drop).

In both tasks Philips was faster than Pioneer. Notice however, that the difference is significant.
