What I love about those miniature data disks is that they represent everything about the Y2K epoch before it was clear that internet streaming was going to completely upend everything. Before roughly the late 2000s, it wasn't that clear that the internet was going to so totally change life like it has, despite how mainstream the internet was even in the mid-1990s, all because bandwidth was so low and connection speeds left much to be desired. Going back further into the 80s, it was harder still to predict that we were so close to an era of simply being able to download entertainment remotely (though France obviously had a taste test of this).
Flash storage persists, but flash was still ridiculously low-end in the 1990s compared to discs. A CD cost almost nothing to make or buy, while a flash drive with an equivalent amount of storage would set you back around $100+ even in 2001-2002.
Therefore when it came to imagining how to push storage further as well as make it portable (because miniaturization was all the rage), you see all these evolutionary dead ends.
