WebFeb 21, 2024 · How does an optical drive work? Optical drives read and write data to discs by means of a laser. To write, the laser creates pits in an organic dye layer on the surface of the disc, the reflected light from which can then be read by photodiodes in the drive and converted back into the original data. WebHow do optical drives work? In all three disc formats, data is encoded in flat areas and hollows and stored in spiral tracks on circular disks. The flat areas are known as lands and represent “1”, and the hollows are called pits and represent “0”. A low-power blue-violet laser beam reads the pits.

WebWhen reading from an optical disk, a laser is shone onto the surface and focussed onto a part of the track. Some of the light will be reflected back from the disk and the amount of this is measured.Continuing along a pit or land causes most of the light to be reflected, but transitioning between the two causes the light to be scattered (so a ... WebAn optical encoder is a type of rotary encoder that uses a sensor to identify position change as light passes through a patterned encoder wheel or disk. The LED shines through one side of the optical shaft encoder. The encoder wheel or disk has a series of tracks on it, similar to the concentric grooves in an LP.
