Anyways, in a visual sense, both DVD media types appear just the same and may have identical storage capacities. The difference primary lies on how data (i.e., files, photos, videos, etc.) are written or burned on those medium. You might ask: “Why in the world are there two types of formats?” or “Won’t they make it just easy for us consumers to just manufacture them in a standard format?” That was what I was thinking and pondering before. Unfortunately, the manufacturers of these blank media could not agree with other. I’m not exactly sure why, but I guess that it is a matter of marketing strategies or trade secrets. In the blank computer media world, there are two groups who are advocates of each DVD format. Each group claims that their supported format is better than the other. But as far as my experience with blank recordable media goes, both formats have been satisfactory to me.

One group is called the DVD Forum which supports the DVD-R/DVD-RW format (composed of major manufacturers Sony, Hitachi, Mitsubishi, etc.). On the other hand, the other group is called the DVD+RW Alliance which supports the DVD+R/DVD+RW format (composed of Sony, Phillips, Dell, Yamaha, etc.). Note that Sony belongs to both groups (What a wily guy, eh?). In the early days of the DVD, problems arose when players or drives (not burners / writers) are not made compatible enough to read both formats. Fortunately, most DVD players or drives that are being sold these days are already compatible with both formats. But just to make sure, please check with the vendor or manufacturer if the DVD player or drive can support reading from both formats. When it comes to prices, there is not much difference among the two. However, please take note that the RW types (DVD-RW and DVD+RW) cost much more than the R types (DVD-R and DVD+R) simply because they are rewritable media.

In a nutshell and keep this in mind, when it comes to burning discs, DVD-R/DVD-RW recordable media discs will not work on a DVD+R/DVD+RW burner/writer and the other way around. So better make sure what type of DVD burner you have before buying a blank DVD. However though, when it comes to playback or file reading, both formats are compatible with most new models of DVD drives and DVD players that are available these days.

Many branded CDs and DVDs are not manufactured by the brand name holders themselves. That is, the production of these media is outsourced to other companies of which are mostly located in Japan, Taiwan, China, Singapore, India, Austria, Korea and Malaysia. Yes. Those are mostly eastern countries. However though, many experts have claimed that the best ones are coming from Japanese manufacturers. Japanese companies such like Mitsubishi Chemicals, Mitsubishi-Kagaku Media are the current outsourcers for the brand name Verbatim. The Maxell brand is another that is sourcing its blank DVDs and CDs from the Japanese company Hitachi. In addition, another popular and reliable branded media, JVC, is another Japanese company that outsources its blank media to a Japanese company called Taiyo Yuden. Sony is another manufacturer of blank CDs and DVDs which sells them under its own brand. TDK is another manufacturer that sells its blank computer media under its own name. However, TDK is based in Taiwan. There are many other brands that compete with the brand names just mentioned but in most claims by experts, they do not match the quality of the mentioned brands.

As a result of the above, the old but still reliable Cathode Ray Tube televisions have started to be out of the whole picture. Seldom can one see a CRT TV on display at major electronics and appliances stores. Although CRT TVs are still much around, although in much smaller numbers, many manufacturers have ceased making them especially now that the prices of the more advanced television has dwindled to affordability because of stiff competition among the manufacturers and vendors. Much of the CRT TVs one can still see at home are remnants of the olden times. As a matter of fact, CRT television is one durable piece of item that is why many are still standing in many homes (although as secondary units in many cases).

With all the hype that is revolving around Blu-ray media, this media technology is still considered very young. Although, Blu-ray compatible players have started to crop up on some electronics shops, there are still numerous existing media players that are still not compatible with Blu-ray discs. One factor that has restricted the Blu-ray’s demand among the consumers is its price. Currently, Blu-ray discs are still priced high as well as their compatible players. Despite the benefit of higher quality images, Blu-rays still have a long way to go.
