Poseidons dvd learning thread and Danderzones computer blow up

[Poseidon]

Just checked with Gamespot, of which I happen to be a proud member, and the new game is listed for PC also. Anything to say?

[Dangerzone]

what are you saying?........

the game is for pc only,(for the moment), did you think that we did not know that?


those stats i rambled off were about the graphic quality of the pc game (which is exterely good)

[Poseidon]

Yeah, PC but DVD, right?

[Dangerzone]

from what i gather it will be on PC-DVD ROM

i have no knolege of a CD version, there may be one, but i do not know
i would be safer than sorry and prepare for a dvd only launch

DVDs can be used for data now, not just movies

and the only diffrence between CDs and DVDs is the amount of info it can hold


a single CD can hold 700 MB of info or aprox 0.5 GB
in the past 3 CDs were used for each game so that equals 2100 MB or 1.5 GB

a single dvd can hold up to 4.5 GB on a single disc (DVD-5 Disc)
and there is another kind of dvd (called a DVD-9 Disc) that can hold up to 8.5 GB on a single disc

both types of dvds will work in a standard dvd drive, but when you think about it.......
you can ad up all 3 of the previous games (1.5 GB X 3 = 4.5GB) and you still only have half of the possible size of this game, bacause it can go up to 8.5 Gb.......

Now do you see the advantage of DVD VS. CD

if the game was on cd it would be........
9 CDs for DVD-5
or 12 CDs for DVD-9

give me a minute i will post some info on how cd drives and dvd drives work

(i just have to copy and host some pictures)

You turned on a fluorecent lamp (bulbs extremely hard to come by) in my room!

fiat lux - well let me shine more light on your situation
for here is how CDs and DVDs actually work
(the pictures below were copied from david macullys "the new way things work", and from the box my dvd drive came in)
-------

ok do you remember the old vynal records, and how a needle traveled in a grove
a cd/dvd drive works similar to this, only it uses a laser

in a CD there are microscopic holes in the polycarbonate disc
they look like this up close

(that is a drawing but you get the point)

and a computer reads these bumps and holes as ones and zeros (binary code)

when there is a hole, the laser does not reflect, this is read as a "1"
when there is a bump, the beam reflects back down toward the laser, this is read as a "0"

here is a drawing


_____________________________________________

in a DVD the pits and bumps are even smaller
and a dvd is actually 2 discs
one glued to the top of the other

the laser has the ability to read the bottom disc, or it can shoot through the bottom disc and read the top layer
here is a picture

the laser on the left is reading the upper layer
the laser on the right is reading the lower layer

and on a DVD-9 disc
the bumps and pits are 2x smaller

Sure do, I played enough of them in my time. I'll even go you one further: I even remember the thick red vinyl records that were the intermediary step before 33 1/3's came out. My father had one of them. We never played it because we didn't have the proper needles for it. So, the DVD uses lasar just like the CD ? Interesting! And I remember the binary code because they taught to us in high school. So, I get a two -for-one deal with a DVD whereas with a CD I don't? I'm sold!
