For those unfamiliar with LASERFiLm, go ahead and read up on all the information available about it on the Internet. It should take all of about 5 minutes.
This video shows the unit a bit but not much else. There is some information from a previous employee of McDonnell Douglas in the comments of the video.


There is a little blurb about it here:
https://en.wikipedia.org/wiki/Laserfilm

And here:

If you are wondering why I type it "LASERFiLm" please look at this logo and tell me I'm wrong.

Since the chances of finding a disc to play on this are slim, I have taken it apart for never before seen pictures and trying to trick it to play.
You are going to have to excuse the poor quality of the pictures as I invest my money in useless A/V equipment and not in fancy cameras.

Here is the front panel:

The back:

If the transport screw is set then this message is displayed on the screen:

Silly LASERFiLm, I already have screws loose.

Laser Assembly:
The White plastic hook on the left tells the unit a disc is inserted. The black plastic in the middle rides under the disc and has an optical reader which picks up the laser through the disc. I think anyways.
Image
The sleigh unit straddles the disc. The big circle is the laser:

The component to the left of the screw is what I mentioned earlier as the optical reader. The best way to get replies on this thread is by saying something wrong so I'll just stick with it being an optical reader regardless of if it is or not.

The spindle hub is about the size of a cd. I tried to play several things in this player to trick it including: CD, VHD, CED, piece of cardboard, and a piece of film negative. The CD was too small as you can see in this video and the VHD/CED center hole was too large for the spindle hub to grip.


Here is a top view of the system seeing if there is a disc:


Here is what is showed on the TV screen during the process above:


And finally this is what the laser does during the process above:


In case you were wondering about the model number (LFS-4400)and power specifications:

So there is the write-up on LASERFiLm you never wanted.

There was one of these a few years ago at a thrift shop in Ventura, but I didn't bite because I knew I'd probably never find a disk for it :(

Made in Japan is surprising. You'd think McDD would be all American.
