Mass Data Storage

Transferring information to optical disks is one possible solution for companies that require mass data storage. The two predominant types of optical disks are magneto optical (MO) disks and ultra density optical (UDO) disks, the most recent breakthrough in laser-reading technology. Optical libraries consist of either disks that can be rewritten or those that can be written only once.

MO disks, which use red lasers, store up to a 9.1 GB of information. These disks store files after heat changes their surfaces. When information needs to be altered, the disks are reheated, updating the stored data. Because they can be edited, MO disks are used primarily for short-term or intermediate-term mass data storage.

Write-Once Disks for Mass Data Storage

UDO disks differ from MO in that they use the more compressed blue lasers. Because blue light has smaller wavelengths, these disks can store more information than MO disks. UDO disks are available in write-only format, which means that stored data cannot be altered. Laser encoding makes it physically and chemically impossible for information to be changed once it's been saved.

This technology enables businesses to maintain library integrity, a major legality issue pertaining to mass data storage. Businesses can use UDO-write-once libraries to prove document authenticity and remain in compliance with regulatory standards. The SEC, IRS, and other organizations are currently in crackdown mode because of the recent influx of corporate scandals.
