• Comparing how the recording speed(s) (4X-48X) affects writing quality using PleXWriter PX-W4824A
• Comparing various 48X writers
• Comparing various 52X writers

In order to compare Plextor's VariRec, YAMAHA's AudioMASTER and TEAC's "4X Boost" technologies we burned using the same disc type:

RITEK 80min 48X (JS Type)
Code : 97m15s17f
Disc Type : CD-R
Recording Layer : Dye Type 7: Short Strategy (Phthalocyanine)
Capacity : 79:59.70 (703 MB)

, the same amount of data (80:07:44), with the following drives:

• PleXWriter PX-W4824A (firmware v1.03)
• YAMAHA CRW-F1E (firmware v1.0d)
• TEAC CD-W540E (firmware v1.0H)

All discs measured with LEADER LE-1853 CD/DVD Analyzer using the SEISANKA CD-ROM reader calibrated with Philips Calibration JT.1 test disc. The correlation factor for the 3T Land is 0.9975, while for the 3T Pits is 0.998. The reading speed for all discs was 1X.

The PleXWriter PX-W4824A and TEAC CD-W540E can write the full capacity of the used media (80mins), while the YAMAHA CRW-F1E only 67mins (due to higher pits length). That's why the YAMAHA graphs stop at 67mins. In addition, we burned two discs under the AudioMASTER, one at 8X and one at 4X to see if there the recording speed does affect or not the AudioMASTER technology.

The three technologies promise optimal results at the 4X writing speed, lets see if this is true!
