Similar to the plastic gears in old PC Engine cd drives, it's a somewhat well known issue with the cd drives in the FZ-1 and FZ-10 that a particular small plastic gear that helps to move the laser assembly gets brittle with age and can crack - and once cracked, the entire drive basically stops functioning (discs don't spin, the laser doesn't do anything). Sometimes people think they have a dead laser when in fact the only issue with the cd drive is the cracked gear. Sometimes people refer to this as the "worm gear" but its not really a worm gear (though there is one of those in the drive as well). I've owned 4 3DO consoles and encountered this cracked gear on 3 of them, you don't even need to have been running the console particularly frequently or with hard use for the crack to occur.
Here's the gear I'm talking about
If you want to try and source a new gear without buying broken 3DOs or 25 year old Matsushita cdrom drives that might have equally brittle gears, take a look at the following bits of information other folks have recomended to get a solution. Source listed above the quote.

If you have a 3D printer, you might try the following model of the gear fashioned by an individual at assemblergames.com and used to success

If anyone has the cracked gear in their FZ-1/10, you can get a replacement worm + motor gear from Gizmoszone.com, Part no GM0.5-14-19 (motor gear), and GW0.5-01-14 (worm gear).
You'll need to drill the hole in the motor gear with a 1/8 bit so it fits properly (and use a drop of superglue to keep it solid).

Part No.: GW0.5-01-14
costs $2.50 and they had a $10 minimum
so ordered more worm gears but only that one fit. it wasnt a perfect fit was loose on the other end but tight on one end. to make it fit i needed to cut the tight end:

i used krazy glue to make sure it would stay on tight. crazy glue is used alot for gears in the RC and mini heli world and they do hold on tight and forever. so no worries of it coming loose. and since this was the only place i could find that had a worm gear close enough to what i needed i had no choice.

you can see it as it fits like a glove assembled:

powered on its a little louder than before but it works. hours of playing and no problems.
the specs on the original gears:
worm
7mm long
5mm wide
1.5mm hole
gear
9mm wide
3mm long or 4,has small groove
2.5 mm hole closer to 3mm
replacement
8 mm gear,was drilled to fit shaft
worm gear was cut to fit

Success! I gave the gear to the guy I work with and he remade the gear in no time just measuring. It worked pretty well, not perfect though. I had to loosen the screws that hold the motor down by 1/4 a turn. Not sure if this was because the teeth were too long or to thick. He did say he it was hitting the limit of how tiny the printer could go. The printer is a Makerbot, I think one of the first ones that came out. That said, it might be a little louder but I don't remember what it sounded like before. Everything played perfect though.
