There was also a concept of using multi wavelength lasers and multi layers per disc so as to stack layers of data that could be retrieved with a specific wavelength only.

But none of this has happened and a spinning mechanical deal is a lot of wasted space as chips are following moores law, I just cant see it being able to compete with chip memory, some of which is so tiny that it doesn't hold a charge, it has to be energized to see how the molecule was positioned giving binary storage infinite lifespan.

The multi layers per disc did work and is used today, but for some reason they couldn't go beyond two layers.

You are right about the improving technology and Moore's law, but if they could really store 1000 terabytes on a disc I can see it continuing to compete for a long time.

Hopefully nobody minds our necro posting, it's my fault for bringing it up, but it is an interesting subject and something may still come of it.
