Writing Quality Tests - 3T Jitter Tests
The same Nero compilation used in the previous jitter tests was used once
again, this time with media from different brands. The recording speed was
the maximum
in all cases. The following graphs indicate the 3T Pit & Land Jitter results.
- 3T Pit results
According to the results we took from the jitter measurements, CyberDrive
performed very well with all media brands. The CMC Magnetics, Maxell, Philips,
Mam, Primedisc
and Samsung prove to be very good combinations with CyberDrive recorder. The
Samsung media returned
good jitter results.
The average 3T Jitter values for all manufacturers discs are illustrated in
the following graph.
- 3T Land results
The jitter land values were almost at the same levels with this one of 3T
Pit.

- Summary
The drive performed very good with CD recording tests with all the media brands
we tested. The writing quality is high for all. There wasn`t even one
case that we could see increased jitter values over 37ns at 32x recording.
On the following page we check
the C1 and C2 error rates for the same discs.
