Magneto-Optical Drives


Magneto-Optical (MO) is a technology that is used to read and write CDs. You need a Magneto-Optical drive to read and write data on a Magneto-Optical CD. The working of the Magneto Optical drive is based on a laser beam, which writes data on the surface of the CD. Magneto-Optical drives are ideal for offices, organizations or business units to keep a large volume of data backups.

Blu-ray


Developed by Blu-ray Disk Association (BDA), Blu-ray (also known as Blu-ray or BD) is an optical storage medium that records, stores and plays high-defination videos and digital audio. Blu-ray uses a blue-violet laser, instead of a red laser that is used by current optical disk technologies, such as DVD,DVD±R, DVD±RW and DVD-RAM to read and write data. Blu-ray can store about 25 GB of data on its single-layer disk and up to 50 GB data on the dual-layer disk. In addition it has a higher data transfer rate of 36 Mbps. Moreover you can have 9 hours of HD Video on a Blue-ray disc or about 23 hours od Standard Definition (SD) on a 50 GB disk.

Similar to CD and DVD technologies, Blu-ray also uses different technologies : BD-R and BD-RW. 

Combo Drive


A combo drive supports the functionality of both a CD-ROM drive and a DVD-ROM drive. In other words, a Combo drive can be used to read and write CDs and DVDs. A combo drive reads CDs at a maximum speed of 52x and DVDs at a maximum speed of 16x. Moreover it writes CD-R disks with a maximum speed of 52x and CD-RWs with maximum speed of 32x.
