A WORM disc looks like a CD. Also, data is read from the disk in a similar way to that on a CD.
The WORM disc surface has 40,000 Tracks, 25 Sectors and a total storage capacity of 1GB.
Data is written into the disc by burning a permanent pattern into the surface of the disc by means of a high precision laser beam.
The WORM discs are exchangeable.
WORM discs are non-erasable & are less prone to data loss compared to Magnetic disks.
Access speed of a WORM disc is slower than that of Magnetic disks.
To use the WORM discs, a WORM disk unit/drive is needed. The drive is similar to magnetic disk unit.
An example of a WORM drive is the CD-R, which uses the same size of disks as CDs and once written using the CD-R drive, it can be read in a CD-ROM disk drive as well as in a CD-R drive.
