The measure of a jukebox varies with the type of data and how it is used. The difference between M-O and CD-Rom is in the details.
Magneto-optical disk jukeboxes were once the favorites for mass storage, but have recently fallen on hard times. Network manages in search of large-capacity data storage are instead turning to tape libraries and CD-ROM jukeboxes. But for storage requirements, M-O jukeboxes may still be the best choice.
M-O jukeboxes are the product of proven, scalable technology. M-O has advantages over other storage options. M-O is cheaper in large capacity applications.
But there are also downsides. Although single M-O drivers are not as cheap or portable as CD-ROM drives, single disk drives are available in compatible formats for use with PCs. That makes the data on M-O disks portable and not accessible only through a giant and expensive jukebox.
