Welcome to our Guide to Optical Storage

SCSI Interface
There are a number of connectors, including high-density, low density, Mac, PowerBook, Wide, and SCSI-3
Typically either low density (centronics) or high density (SCSI-II) connectors on most devices. Mac and PowerBook are Apple specific, and older host adapters have the low density, newer adapters have the high density or WIDE and UltraWide connectors.SCSI Zip drives use a Mac cable.
The Adaptec 2940UW controller has 1 -68pin internal and 1-50pin internal, 1-68pin UW external
Differential SCSI allow the chain to extend beyond 6m.

The increased stability of CD-Recordable media and recording are due to advances in Hard disk transfer rates (and cost), 2 MB RAM buffers on the recording drives, the dye improvements from Mitsui, and have resulted in fewer wasted blanks, long shelf life, and lower costs. CD-R is valuable for fiscal archives, multimedia, product information and software distribution, music, publication on demand and more.Increases in speed of readers,a wide installed base of CD-ROM, the new CD-RW and the promise of DVD compatability, coupled with the low cost and high availability of media make CD-R cost effective format.
