The system is called "LightScribe" The official site is

Not anyone I know of actually sells the DVD media yet, though you can
get on a waiting list for Memorex DVD+R for about $20.00 a 10 pack
with jewel cases at a local big name shop. CD media is somewhat
easier to find, I last priced it at $10 a 5 pack with jewel cases.
So presently either or for $2/per. I know of no DVD-R for this
system.
The idea is sound enough but it's hardly what i'd consider to be a buy
it now technology. It has the obvious benefits no run no jitter won't
rub off printing with a fixed cost of consumables. But the write time
is massive. I haven't actually timed my Epson R200 but it's no 45min,
it's no 5min.
I don't have an accurate cost of ink/disc estimate for my Epson R200
but I have printed over 200 CDs, at about 25% color. Needless to say
at present buying inkjet printable media and using an inkjet printer
is over 1/2 the price of the HP solution. This may change later.
