Advice regarding blank DVD discs

From today’s mail bag:

I need to purchase some new DVDs. I kept a post you made about a year ago when you recommended the Taiyo Yuden DVDs and that you burn DVD-Rs. Does this advice still hold true? What do you use? I see that the supermediastore has silver, premium silver, and lacquer, etc. Which should I order? I have a MacPro with a 16X SuperDrive DL.

Also, it was suggested to me that I also get some dual layer DVDs to hold larger files. Do you have a recommended type for those, too? Currently, I’m using the DVDs mainly to store audio files off site.

I still use single-layer, DVD-R discs from Taiyo Yuden to burn video and data DVDs. I haven’t changed brands and haven’t had a need to order new supplies, as my usage has been minimal.

Optical disc devices perform their magic by aiming a focused beam of light towards a reflective disc layer that contains either gold, silver, or aluminum. Silver or aluminum discs are susceptible to corrosion or oxidation if continually exposed to environmentally unfriendly conditions such as moisture or sulfur, while gold-based media are immune from these same risks. On the other hand, gold discs cost more than media containing silver or aluminum.

Your Mac Pro can burn both DVD+R and DVD-R media, including two-sided discs that double the storage capacity. Choosing double-sided media sounds like a good idea at first glance. However, if you opt for double-sided media over single-layer, do so with the understanding that the hardware in your Mac will soon be rendered obsolete by Blu-ray recording devices that can store five times as much data on a single disc in support of the new, high-definition TV standard that will take effect in 2009.

Blu-ray Disc

Blu-ray, also known as Blu-ray Disc (BD), is the name of a next-generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world’s leading consumer electronics, personal computer and media manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs will offer consumers an unprecedented HD experience.
