| Sep 26, 2008 - Why DVD+R(W) is superior to DVD-R(W)? -06 |
Conclusion
During my study of rewritable DVD formats it seemed very clear to me that DVD-R(W) standard was not as well designed as DVD+R(W) (or even DVD-RAM). And although some serious efforts have been put in the latest revisions of the - format to fix some of the original problems (at the cost of a much increased complexity), it still remains technically inferior to +, due to some intrinsic weaknesses (e.g. pre-pits). This is not very surprising, as Sony and Philips have a much longer experience at defining standards than Pioneer (and several key patents), and they also had the advantage to publish their standards after their competitors.
Although the arguments presented in this document might look like technical details to most readers, disc format is what defines the limits of what drives can do with a given medium, both in terms of performances and features. Therefore, the technical advantages of the DVD+R(W) format will with time turn into faster, more powerful and more reliable drives for end users. This is already the case today, and the gap will continue to increase as DVD+R(W) drives will exploit more and more of the advantages of the + format. However, as history showed, the best ideas are not guaranteed to win on technology markets, and only time will tell which format becomes the new standard.
This article is meant to be a list of technical arguments showing some of the advantages of the + format over the - format, and it reflects only my personal opinion, and not the one of CD Freaks. It is not a detailed comparison of the two formats, and it does not take into account specificities of drives, media or third party software : only the format differences are compared here, as described in the DVD-R 2.0, DVD-RW 1.1, DVD+R 1.1 and DVD+RW 1.1 standards.
