Question

Advantages of optical disk??

Answer 1

Heyya !!!!

Optical media offer the following advantages for storing data over conventional magnetic disks:
⊙Mass storage capacity (on the order of gigabytes)
⊙Mountable/unmountable storage units
⊙Low cost per bit of storage
⊙Long media life
⊙High data stability

Because optical media are written to and read with a laser, a bit of data is written to a much smaller area on the optical platter(disc) than the area that is required to record a bit on a conventional magnetic disk. Optical platters offer a high degree of stability because they are far less susceptible than magnetic disks to corruption by environmental influences such as electromagnetic fields. Furthermore, the possibility of a read/write head crash is remote because the optical disc read/write head does not come as close to the platter as the magnetic disk read/write head.

I hope this helps you!!!
