Blank CDs, DVDs & Blu-Ray Disks
CDs, or compact discs, are a versatile data storage medium. Blank CDs are designed to be used with CD burners to copy information from a computer device onto a physical medium. Blank CDs are also used in mass production with commercial burners to release identical products for the consumer market. Unlike DVD-R discs, CDs are not an optical medium and have a comparatively limited data capacity. As such they are usually only used for audio and file data. Most DVD players are optimized for DVD discs, and so won't read CD formats. Blank CDs are available in two specific types, which are CD-R and CD-RW. CD-RW are re-writable, and so can be used time and time again.CD-R discs are non-re-writable and can't be erased and re-written.
DVDs (Digital Versatile Discs) are compact discs designed to store a variety of data such as video, audio and multimedia files. Blank DVDs are similar to blank CDs but with a higher storage capacity, they can hold up to 13 times the information of a standard CD. The difference between R and RW is that DVD-R is a write-once recordable disc whereas the DVD-RW is a rewritable disc. Packs of blank DVDs are commonly supplied on a spindle or in a jewel case.
Blank Blu-ray Discs
Blu-ray Discs (BD) are a digital optical disc data storage format. The discs were designed to supersede the DVD format, increasing the storage capacity, therefore allowing hours of video in high-definition and ultra-high-definition resolution to be stored. The main application of blank Blu-ray discs is for video material such as feature films and for the physical distribution of video games for games consoles.
