) the ideal resolution of a player using a laser (such as a blu-ray player), which determines how close together data can be stored on a compact disk, is determined using the following formula: resolution = 0.60(?/na), where ? is the wavelength of the laser and na is the numerical aperture. numerical aperture is a measure of the size of the spot of light on the disk; the larger the na, the smaller the spot. in a typical blu-ray system, na = 0.95. if the 405-nm laser is used in a blu-ray player, what is the closest that information can be stored on a blu-ray disk?
