Common Benefits of Recordable CD and DVD duplication
Both CD and DVD technologies offer many benefits in the corporate IT world, starting with the highly portable nature of the drives and media. No one would dream of lugging a magnetic tape drive around on the road, but every notebook computer maker offers optional or built-in recordable CD and DVD drives, or combo drives that can handle both media. The discs themselves are very lightweight, yet relatively durable, especially compared to tape cartridges.
CD/DVD discs are ideal for transferring large amounts of data or files from one system to another. Whether you are transferring data, audio, video or image files, there is an optical disc that will suit your needs. CDs can be written in under three minutes, while DVDs can be written in less than 15 minutes. And with advanced recording features such as BURN-Proof, it is nearly impossible for users to create “coasters.”
Cost is another factor that goes in favor of CD and DVD. When purchased in bulk quantities, the media costs a fraction of a cent per megabyte, and the prices of drives keep falling. Compared with other segments of the removable storage industry, the CD/DVD market is dominated by large multinational companies with well-known brand names, so there’s little risk of buying a dead-end solution from a company that won’t be around to support it tomorrow.
Overall, it is relatively easy for IT departments to feel comfortable about purchasing CD and DVD recording technology because it’s stable and inexpensive. At the same time, the small data storage capacity of CDs makes them somewhat less useful compared with the much larger capacity of DVDs.
Data Storage and Backup Applications
As computer systems and their associated applications grow, demands on data storage also increase proportionally. Five years ago, a hard drive of two gigabytes might have been sufficient for most office applications. Today, 20 gigabytes is probably closer to the norm.
One reason is that individual application files keep getting larger and larger. Data is no longer restricted to simple text or numerical form, but encompasses multimedia and high-quality image processing. A single PowerPoint presentation, for instance, may include embedded audio, pictures, or even video clips, resulting in a file size that exceeds one gigabyte!
Currently, erasable optical storage is too slow to be used as a computer’s main storage facility, but as the speed improves and the cost comes down, CD-RW and DVD-RW devices are becoming a popular alternative to tape systems as a backup method. One important advantage in this age of the “mobile knowledge worker” is that CD and DVD burners provide individualized backup of standalone computers, including notebooks, whenever and wherever you want it.
Sometimes people simply need to take work home from the office-or maybe they telecommute regularly from home. Most people don’t have magnetic tape or magnetic disc drives built into their home PC, and the floppy disk’s miniscule capacity renders it obsolete. CD/DVD is the only removable media with sufficient capacity that works at both home and office.
Optical media is also perfect for storing archives of critical corporate data, such as financials or personnel records. Just consider the average predicted lifespan of various data storage media, and then ask yourself which one you would use to preserve your most precious family pictures:
* Magnetic Discs — 1 to 5 years
* Magnetic Hard drives — 3 to 6 years
* Magnetic Tape — 10 to 20 years
* Recordable CD — 30 years
* Recordable DVD — 70 years.
Customer and Corporate Communications
CD/DVD is easy and cheap updateable publishing media for enterprises. This makes optical media very useful in a broad range of both internal and external communications applications. For example, a sales force wants to present a digital brochure to customers. The brochure includes interactive presentations with rich multimedia content that people can navigate and view at their own pace. Only a CD/DVD can provide the storage capacity and the universal playability required for this application.
Other examples of communications applications include menu-driven annual reports for shareholders; interactive workforce and management training; distributing large amounts of updateable documentation such as product catalogs; and distributing software, training videos, etc.
Recordable CDs and DVDs make all of these applications much easier and less expensive to distribute than paper, video, or any other data storage medium. CD/DVD is even less expensive to mail than videotape; and video on CD/DVD does not rapidly deteriorate in quality, unlike videotape.
CD-RW is rapidly becoming the de facto standard for removable data storage on both consumer and corporate PCs. As CD technology dovetails into future DVD technology, recordable optical storage continues to provide real value to corporate IT departments. The value of this technology will only grow as the data storage capacities of discs get bigger and the data transfer rates of drives get faster.
In early 2002, the DVD Forum’s Steering Committee announced their support for a blue laser successor to the original DVD format: the “Blu-ray Disc” format. The DVD Forum itself voted to approve the use of a completely different low-bit-rate compression technology for High-Definition DVD (HD-DVD).
Whatever the outcome of this latest industry standards face-off, we do know that the current generation of DVD technology uses a red laser to achieve a 4.7GB capacity (single-layer disc), while next generation HD-DVD will use a blue-violet laser to achieve capacities of 27GB (single-layer disc) up to 50GB (dual-layer disc). This dramatic increase in capacity promises to fuel future demand for optical data storage products in the enterprise.
