To recall, blank computer media, which usually connotes optical storage devices, have evolved quite considerably since advancements in laser technology made it possible to write and read massive amounts of data on a single portable storage medium. First, there were the big-sized laser discs which came out as a huge favorite due to their capability to store data in high-quality fashion. Then the much smaller sized compact discs (CDs) came in next which instantly made the laser discs obsolete. Then, the more advanced DVDs outshined the CDs due to their capability to store much larger amounts of data on a similarly sized optical disc. But currently, Blu-ray discs have emerged as the latest hotshot in optical media. However, Blu-ray discs have not yet fully taken off to their huge price tags which somewhat came as their primary drawback. This drawback has made many businesses still stick to the less costly CDs and DVDs which have proven to be useful and reliable in backing up their vital data.

CDs have standard capacities of 700MB which can hold various data file types such as videos, audios, photos and document files. They are mostly available in read only types (CD-R) and read-write types (CD-RW). DVDs which have much higher data capacities can hold around 4GB of data making them a huge boon for many businesses and home users as well. There are also discs which are capable for Lightscribe labeling making it more easier to label each disc for efficient indexing and identification.

These computer media are widely available in every computer shops and in every computer supply stores. In addition, even many bookstores carry them in their inventory. The greatest value for money can be had when purchases are done in bulk because most vendors will offer discounts and some added perks. Since many vendors are now making their presence online, purchasing them has been made much simpler and easier. However, with so many manufacturers vying for a good piece of the market pie, many brands have cropped up making it somewhat cumbersome which one to choose. Popular brand names such as Imation, Maxell, Sony, Verbatim, Prodisk and Memorex, just to name a few, have been making a killing out of their sales figures. Several online reviews on brand names can also be found making it immensely helpful in coming up with a well-informed decision when buying a blank cd or blank dvd of your choice.
