   Comparison of several forms of disk storage showing tracks (not-to-scale); green denotes start and red denotes end. * Some CD-R(W) and DVD-R(W)/DVD+R(W) recorders operate in ZCLV, CAA or CAV modes. In optical storage , constant linear velocity ( CLV ) is a qualifier for the rated speed of an optical disc drive , and may also be applied to the ...

   In the history of optical storage media there have been and there are different optical disc formats with different data writing/reading speeds.. Original CD-ROM drives could read data at about 150 kB/s, 1× constant angular velocity (CAV), [1] the same speed of compact disc players without buffering.

5. Optical disc - Wikipedia

   en.wikipedia.org/wiki/Optical_disc

   An optical disc is designed to support one of three recording types: read-only (such as CD and CD-ROM), recordable (write-once, like CD-R), or re-recordable (rewritable, like CD-RW). Write-once optical discs commonly have an organic dye (may also be a ( phthalocyanine ) azo dye , mainly used by Verbatim , or an oxonol dye, used by Fujifilm [ 4 ...

6. Density (computer storage) - Wikipedia

   en.wikipedia.org/wiki/Density_(computer_storage)

   Compact discs (CDs) offer a density of about 0.90 Gbit/in 2, using pits which are 0.83 micrometers long and 0.5 micrometers wide, arranged in tracks spaced 1.6 micrometers apart. DVD disks are essentially a higher-density CD, using more of the disk surface, smaller pits (0.64 micrometers), and tighter tracks (0.74 micrometers), offering a ...
