Optical storage uses what for 0s and 1s
WebThe laser sends out a light ray, and the sensor will detect the reflection. If the sensor doesn’t receive a light ray, the microprocessor will record it as a 0 leading to a series of 1s and 0s that your computer processes to audio or video. This use of light technology is why DVDs and CDs are categorized under optical storage media. WebTo write data onto a disc, the optical drive uses this type of laser to make a series of microscopic marks in the dye. The resulting sequence of light and dark spots (pits and lands) represent the digital ones and zeros that comprise your data. DVD uses 650 nm wavelength laser diode light as opposed to 780 nm for CD.
