Speaking of this, I always thought this would eventually be addressed with disk based content via multiple lasers. Remember the old
Kenwood 7 laser CD drives where it could read at 72x? The kenwood 72X drive didn't actually spin the disc at 72x, it spun the disc at 10x, and used 7 lasers to read 7 times as much per revolution. This also had the advantage of not having high spin speeds (quieter). It also would have access to that 72x rate at all times and not just on certain parts of the disk.
But it never took off for whatever reason.
