Blank Dvd Discs - Purchasing the Right Blank DVD Discs - DVD-R vs. DVD-RW, +R vs. -R

purchase variety varieties difference

Shopping for blank DVD discs may seem like an easy job. However, there are a few things you should know about blank DVD discs before you go out and purchase any. For example, do you know the difference between a DVD-RW disc and a DVD-R disc? Also how do you know if you are getting the best possible price on blank DVD discs? Here’s quick guide to purchasing blank DVD discs.


The first thing you should understand before purchasing any blank DVD discs is the difference between DVD-R discs and DVD-RW discs. The difference between the two is very simple. DVD-R discs can only be written to one time, while DVD-RW discs can be written to as many times as you want. This means that you only have one shot to put everything you want on a DVD-R disc. You cannot go back and add additional information later on. However, DVD-RW discs can have data added to whatever is already on them, and they can be formatted for later use if you want to wipe out all of the data that is on them.

+R vs. -R

It is also important to take note of what kind of DVD drive you have. In addition to blank DVD discs that can be used either once or more than once, you also have to choose between the plus or minus variety. This means essentially that blank DVD discs can take the form of any of the following: DVD-R, DVD-RW, DVD+R, or DVD+RW. The R and RW notations for the plus variety are the same as for the minus variety. The only real difference in the plus or minus versions depends entirely on what kind of DVD drive you have. Some drives will take either, while others are restricted only to either the plus or minus variety. The plus variety was actually created with the intent to make computer DVDs more compatible with home DVD players, but it does not necessarily mean that the discs will play in your DVD player.


One thing that should be noted right away about the plus and minus varieties of blank DVD discs is the fact that the +R and +RW usually cost more than their minus counterparts. This is because the plus varieties are actually a slightly newer format. Also consumers should realize that RW discs of both varieties tend to cost more simply because they can use them more than once.

There are a couple of different ways to purchase blank DVD discs. The least expensive way is to purchase a spindle of blank DVD discs. This allows consumers to purchase them in bulk, although they do not come with a case for the discs. Consumers have to purchase a separate package of cases if they wish for the discs to have cases. The price of a spindle of blank DVD discs ranges widely from $10 to $50, depending on where you purchase. Typically online retailers are less expensive than purchasing them in a store.

Other Features

There are also a couple of other features that it pays off to understand. First of all, recording speed basically tells you how fast the discs can be written to. Some common recording speeds include 8x and 16×. Higher numbers mean faster recording speeds and sometimes higher prices.

Also take note of the amount of space included on the blank DVD discs. The most common space amount is 4.7 gigabytes, which is quite a lot of data. Both the plus and minus varieties can come in any of the common recording speeds and memory sizes.
