Machina Dynamica New Dark Matter CD and Blu Ray tray treatment?

Close enough!! A for effort! PM your shipping address. 

The facts that (1) there’s a threshold of detection for the photodector and that (2) the Red Book committee hired “coding experts” Reed and Solomon, a couple of older conservative types, to come up with some hairy far out error detection/correction codes leads me to believe the original designers knew of this design flaw - scattered background light - but chose to ignore it and cover it up. Another possibility is the reason for the detection threshold was because they knew the light wave cancellation when the laser beam was over a “pit” was not always absolute, that some light would be returned. Or, it’s possible they were just plain ignorant of the problem.

Probably 2 decades ago, someone made aftermarket lens caps to focus the laser which probably acted similarly to NDM. I used them on several player/transports

WOOHOO! I knew those mail order physics classes would pay off! I shall pm you...

Yes there are a lot of straggler lasers out there that need to be focused....

Mail order physics + mail order products = match made in heaven for sure....
