Automatic Disc Recognition

The Automatic Disc Recognition (ADR) mechanism uses the Track Vector (see Automatic Track Recognition section) for the first Track as the Disc Vector for the CD/DVD Disc. The numbers that make up the Disc Vector are converted into a text string that is the name of the Disc File for that Disc. Remember that the Disc File contains all the Track Adjustments for all Tracks on the Disc.

Now it is easy to see how the Stereo Workstation can Recognize a Disc. The Workstation listens to the first several seconds of the first Track of the CD/DVD Disc and calculates the Track Vector for that first Track which is also the Disc Vector. The Workstation then creates a file name from the Disc Vector. This file name is a long string of numbers and is the name of the desired Disc File. The Disc File is then retrieved from the Stereo Workstation hard disk and the Track Adjustment for the first Track in the Track Order List is loaded and the CD/DVD Player is commanded to play that Track. The automation then proceeds as described in the Automatic Track Recognition discussion.
