That would have the advantage over "burned" digital discs of having a
fixing process to make the record permanent.
I'm not sure whether you could get the same resolution as on current CDs
or DVDs, but you might get near it.
The process would never be popular because of the need for a chemical
process, but it could find a niche in archiving. For example, record
companies might like to store their digital recordings in a safer format
now that the copyright period is so long.
