Where 8500 fits
Why 8500 is special
A second recording layer sits beneath the first and is read through it by refocusing the laser. Nearly doubling capacity without changing the disc's physical size is why single-disc films stopped needing a break.

8 × 1,000 + 5 × 100 = 8,500. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
Blu-ray holds roughly three times a dual-layer DVD because a blue laser's shorter wavelength resolves smaller pits. Capacity follows directly from the colour of the light.

Dual-layer DVDs put a second data layer under a semi-transparent first one, and the drive refocuses its laser to read it. The capacity roughly doubles with no change to the disc's dimensions or the player's mechanics.
