It could be but one company I worked for proposed and another used the
idea of writing such data on the disk itself in a lower density area for
the purpose. The OD is preferred because lower density can be had by
using a channel bit rate equal to the ID zone or some other. This made
sense because the mechanical part of a drive plus the head preamps are
more reliable than the electronics board. Plus the electronics board can
be changed without opening the drive case at all.
