Patterns of Light
For nearly 200
years, we have been using light to record
information as photos. Now that we have refined
laser technology, we can use light to store
digital information.
In music stores, the seemingly indestructible CD
rapidly replaced vinyl, but don’t be fooled into
believing that your CD collection will last
forever. For software, music, photos, etc.,
scratches and separation of disc layers can be
major problems.
