WebAn optical disk drive uses a laser beam to read the data from the disk as it is spinning. It distinguishes between the pits and lands based on how the light reflects off the recording material. The drive uses the differences in reflectivity to determine the 0 and 1 bits that represent the data. Optical disk vs. magnetic storage media WebBest. The surface has a magnetic dust embedded in it. The write head can magnetise parts of it as it moves, this is done by making the head an electromagnet and having the surface move below the head. To read the data the head moves through the magnetic field of the tape and this creates a small current. Moving magnetic fields and such.
