Data can be written at GBps speeds

A CD, a conventional CD manufactured in a CD pressing plant, could be basically etched instantly, it would go into a holder and all the pits would be etched at the same time. These machines were of course fantastically expensive though, they had to make 100,000s of CDs to make it worthwhile.

The etching process works twice, ethcing each pit and then verifying it before going onto the next. I doubt this could be done at a fast speed with equipment that was within the price range of say, a state library. I think the author has confused the access time with the writing time.
