2). Are expensive (not economical) especially if used for low storage volumes.
3). Require CD-ROM drives to use the discs, which are not installed on most desktop computers.
4). Most CD-ROMs are produced by the manufacturer or can only be written once. Therefore, they are not reliable especially for businesses that may need to re-programme the CDs to suit their needs.
5). Are slow to prepare, i.e., it takes time to format & also to copy data into the discs, e.g. CD-RW disks take about 1hr to format & about ½ an hr to copy 250 MB of data to the disc.
6). The Access speed of an Optical disk is low.
