Interchangeability – There is no interchange between two drives. Disc written with one vendor’s drive may or may not be readable with the others.
Cost – Optical disc falls in between flash and disk in terms of price and is 10 times more expensive than tape.
Predictions: Optical disc is to be introduced at a 300GB capacity point as write-once. Future drives will allow for backward read compatibility. The storage medium will find favor for customers that have definitive long-term archival requirements where cost is not an issue.
