To read, rather than re-voice that narrator :

And I, a Kurt B. Pilgrim, ironically relives 1987 :
Technical developments may also have an impact on future CD production. A German invention called DMM (Direct Metal Mastering) has been used for some time in cutting conventional LP's. But recently two engineers at Telefunken in Berlin -Joschko Gunter and Horst Redlich -worked out a way to adapt DMM to the manufacture of CD's. The process involves replacing the recording laser, which etches digital bits into the CD master-disk with a beam of light, with a far simpler mechanical device that just punches in all those tiny pits.
Reverting from the elegant laser-optical recording method to more primitive mechanical means may seem like a giant step backward. Conceptually, it is. But the mechanical DMM machine will be about 60 percent cheaper than the $2.5 million laser device now in use, aside from being far less time consuming in the preparation for each mastering session.
These economies of time and money have direct musical implications...
