General Information
This special edition contains instructions on CD-applications with playability problems (i.e.
skipping tracks). The information shows how to check the playability of the set, how to
clean the lens, and how to measure if some important drive parameters like jitter, laser
current and offset values are (still) within the specification.
Background for this information are extensive analyses on replaced CD-drives. It has
been found that a lot of replaced drives were not defective at all, respectively were
replaced for the wrong reason. We are convinced that the procedures on the next pages
will help to reduce the number of erroneously replaced drives drastically and request you
to deploy the instructions to the workshops urgently.
