type: OTHER
Source sentences:
text: The pits reflect light differently than the lands, while a device translates the reflective difference to bits of "on/off" or 1 and 0.
text: Pits and lands reflect the light from the laser differently, and that difference is encoded as binary data: the light hitting a land reflects back directly to a photodiode, which generates an electrical pulse, while the light hitting a pit is refracted (deflected from a straight path, or scattered), and, consequently, reduced below the level needed to activate the photodiode.
text: Once the data has been written, the dye layer is coated with a thin, reflective metal coat that will enable the laser to read data from the differences in the way pits and lands reflect light.
