Princo DVD-R 4x

Quite an unusual situation in this test session, the DVD-R 4x blank from Princo is actually made by Princo Corp.

The disc fully meets the requirements to the maximum of PI failures, but the maximum of PI errors is high above the norm. Thus, we can’t call this disc a high-quality product. You may have problems with it.

RiDATA DVD+R 16x

The Taiwanese Ritek Company founded in 1988, was the first one to produce a CD blank disc in its home country in 1990. In 1992, its production got ISO9002 certified, and in 1997 – ISO9001. In 1996 Ritek produced the first DVD disc in Taiwan.

I decided to mention all these facts here on purpose: to show that Ritek is no newcomer in the optical storage media market, but more like a trendsetter.

The disc sold under RIDATA brand name is manufactured by Ritek Company. Unfortunately, the blank from the round plastic box didn’t meet the allowed requirements for the number of errors. As you can see from the graphs the second part of the disc space turned out to be a major problem. It looks like this disc will not be the best choice if you intend to record it at the maximum write speed.

RiDATA DVD+R DL 2.4x

DVD+R disc designed for dual-layer recording was tested in 2.4x mode. The screenshots show pretty logical results. The entire first layer of the blank disc was recorder beautifully. The quantity of both types of errors, as well as their maximum indicates very high quality of this zone.

However, when we shift to the second layer, the picture changes dramatically. The maximum error rate starts exceeding the allowed maximums according to the ECMA standards, although this is not a global disaster. It happens just a few times and is most meaningful in the very end of the disc space.
