Indicators that the optical media needs to be inspected and cleaned:

E-DOC Magazine Article, May-June 2003 Issue

Optical media can become dirty. Keeping disks clean keeps the information accessible.

You've heard the old television commercial, "Pay me now, or pay me later." Have you recently experienced a situation where you couldn't read or access data? Have you noticed a decrease in access times? Or has your system crashed?

 

This could mean that your optical media has been contaminated - in other words, you have dirty disks. When you have contamination, the data cannot be accessed, you cannot write properly to the disk, and you risk significant downtime.

When that happens it could affect the productivity of the entire organization. Dirt, dust, and grime build up on your media the same way plaque builds up on your teeth. If you don't have semi-annual cleaning of your teeth, they could fall out.

Likewise, if you don't keep your media cleaned on a semi-annual basis, your system could crash. One is detrimental to the health of your body, the other is detrimental to the health of your company.

Optical disk cleaning takes various forms. Some organizations trust their media to a dust-rag and a bottle of glass cleaner, and others try to do it themselves by buying pre-packaged products.

However the most advanced system is automated cleaning. With automation, human error is less likely to occur. Tests have been performed and show that automated cleaning reduces errors due to contamination by reducing a 140,840-contaminant particle count to a 438 particle count as compared to hand or manual cleaning.

Automated disk cleaning can raise your system uptime from 98% to 99.7%. You may think that is a small increase. However in a year's time, a 1.7% increase could net you over $1,000,000 in savings.

For example, one organization has 7,000 users on their system at $20 per hour ($140,000).
