The ideal solution is easier to achieve and has already been implemented once, the hardware is still being manufactured & has competition to keep the cost down & can be used for other things once it's been done & so still has a resale value.
But sure, keep pushing a solution that will produce inferior results and require all the discs to be obtained again at a later date.
