For storing data that is accessed occasionally at large-scale data centers. • For data with reduced frequency of access • It requires relatively fast response times. In the next few years several companies will bring to the marketplace an optical memory drive and a controller. These drive and controller systems will be an attempt at achieving very high capacity. high transfer rate and low cost per megabyte.
Optical media and libraries does not eliminate the need for migrations, instead, using optical discs allows IT managers to avoid forced migrations, moving data around an environment when they want to, not when the media dictates. This saves money and allows for more strategic long term planning. Background: Recordable optical discs can be convenient media for access and temporary storage. Recordable disc formats include CD-R, CD-RW, DVD-R, DVD-RW, DVD+R, and DVD+RW. Unfortunately, these media are machine-dependent, and continued access to the digital content is contingent on the availability of compatible hardware and software. An optical disk is primarily used as a portable and secondary storage device. It can store more data than the previous generation of magnetic storage media, and has a relatively longer lifespan. Compact disks (CD), digital versatile/video disks (DVD) and Blu-ray disks are currently the most commonly used forms of optical disks. An early optical disc system existed in , named Lichttonorgel.  An early analog optical disc used for video recording was invented by David Paul Gregg in and patented in the US in and This form of optical disc was a very early form of the DVD (U.S. Patent 3,,).
