so i have these 5Mw lasers floating around and they are loads of fun to play with! anywho, i have a disc out of a caddy on display and i happened to point the lazer pen at the disc surface, and viola! it makes this neat pattern no matter where on the disc you shine it, even on a daxi band. the more clustered dots is the coarse spiral groove near the hole of the disc...
this is the coarse groove
regular disc surface
both colors
