Hi Michiel,

On 2023-08-22 11:08:57, you wrote to me:

With that that increase in speed also came an increase in content. So better
compression still made sense...

That's true...

A few years back I wanted to read some stored CD's serveral years old, and I
couldn't. In hindsight, it wasn't that surprising. They were stored in the
living room in a rack, where light could get through to them. And they weren't
the best quality, certainly not archive quality...


Bye, Wilfred.
