Optical media maintains growth path
Before the introduction of the CD, it would have been hard to state that optical storage had taken the mass storage industry by storm. Conflicting MO formats were the rule, rather than the exception...a situation that foreshadowed the turbulence regarding DVD formats. Purchases were delayed as the IT community waited out the survivors of the conflict. But with the staggering success of the CD, and the undeniable popularity of CD-R, it is possible to identify optical technology as a storage strat
Optical media options
The optical storage market includes a wide variety of formats. Here`s a quick rundown of the advantages and disadvantages of the major technologies.
