Writing Quality Tests for LiteOn LTR-40125S

We used many media and burned them at various recording speeds with LiteOn LTR-40125S. We used Nero 5.5.7.8 as the CDR software. We burned CDs with "Smart-Burn" enabled/disabled to see the performance gap and the writing quality at both modes. The produced CDs, were measured from DigitalDrives and results are illustrated in the following tables:

- 20x writing speed

Brand	C1		Average Burning Time (mins)
Brand	Max	Average	Average Burning Time (mins)
Taiyo Yuden 74min (24x) Smart-Burn Off	10	0.2	4:10

Rrodisc 80min (32x) Smart-Burn Off	27	1.8	4:27

The C1 error rate is very low with TaiyoYuden media at the 20x writing speed.

- 24x writing speed

Brand	C1		Average Burning Time (mins)
Brand	Max	Average	Average Burning Time (mins)
Taiyo Yuden 74min (24x) Smart-Burn Off	8	0.1	3:40

Rrodisc 80min (32x) Smart-Burn Off	24	1.9	3:53

The drive continues to have low C1 error rate with Taiyo Yuden media.

- 32x writing speed

Brand	C1		Average Burning Time (mins)
Brand	Max	Average	Average Burning Time (mins)
Taiyo Yuden 74min (24x) Smart-Burn Off	38	0.5	3:13
Taiyo Yuden 74min (32x)	11	0.2	3:13
Taiyo Yuden 74min (32x) Smart-Burn Off	20	0.6	3:13

SKC 80min (16x)	24	0.6	3:26
Ricoh 80min (24x)	19	2.6	3:23
Taiyo Yuden 80min (32x)	15	0.6	3:25
Taiyo Yuden 80min (32x) Smart-Burn	20	0.7	3:25

The drive with Taiyo Yuden produces high quality CDs. The Smart-Burn function doesn't seem to affect the total recording time, but affects the burning quality.

The test results showed that at the 40x writing speed, the drive produced a high error rate with the rest media except from the Taiyo Yuden 32x certified. Especially with the Mitsui 74min 16x/24x the drive produces lot of error even with Smart-Burn enabled/disabled. With the Mitsui 24x media, we also saw C2 errors.
