This is not really correct....

The related area is available and writable on DVD-Rs. 

DVD-Rs have been introduced in September 1997. You coul only buy them with an 
OK from the Pioneer boss. In February 1998, I received a sample drive for 
cdrecord development that I had to bring back to the Pioneer CeBIT booth in 
March.... 

At CeBIT-2001 a third generation of DVD-Rs was introduced. This third 
generation introduced a quite different wavelength. It is sold since autumn 
2001 and the media delivered for these drives is prerecorded at the place where 
the CSS key is expected.

If you have good connections to a media manufacturer to get the media before 
the pre-recording starts and if you have good connections to a drive 
manufacturer that produces drives with special firmware for the prerecording, 
you can do ;-)
