Although DVD ROMs are becoming more popular each day, this technology is not without its disadvantages. If you’re planning to buy a new computer or upgrade your current system in the near future, it’s important to understand both the positive and negative aspects of this technology.

A DVD ROM is a compact disc that can hold a minimum of 4.7 GB of movies, music, text, or images, although some discs can hold up to 17 GB of information. Even though movies from the local video store are often referred to simply as DVDs, they are actually DVD ROM discs. Access rates for DVD ROMs range from 600 Kbps to 1.3 Mbps.

Since DVD ROM stands for Digital Versatile Disk – Read Only Memory, it should come as no surprise that this format’s biggest disadvantage it that it can’t be used more than once. Once the information is recorded onto a DVD ROM, it can’t be changed or altered. In fact, most commercially-produced DVD movies contain copy-protection mechanisms to prevent users from creating unauthorized copies of the disc.

If you’re storing data for an ongoing project that you’ll need to change on a regular basis, a DVD ROM is a poor choice. In this case, your best option will be to either use a removable flash drive or purchase a combination DVD+RW/+R/CD-RW drive that allows you to read DVD ROMs and CD ROMs as well as write to CD-R, CD-RW, DVD+R, and DVD+RW discs.

Since DVD ROM is a relatively “new” technology, you may have trouble operating some programs with your DVD ROM drive. For example, Real Jukebox, a music management software program, may not work with some DVD ROM drives. However, it should be noted that most software companies are working to resolve this issue since they are well aware that DVD ROMs are expected to become the CD ROMs of the 21st century.

Of course, unlike a standard stand-alone DVD player, a DVD ROM setup requires a computer. This makes it somewhat more difficult to use a DVD ROM drive as the basis of your home theater system—-although many people, including college students and people living in small apartments, frequently choose this space-saving option. However, if your primary concern is watching DVD movies, you’ll might be better off investing in a high-quality DVD player that is compatible with DVD-R, DVD-RW, DVD+R, DVD+RW, and VCD formats to allow you to view any type of disc that you choose.
