Abstract: This application relates to the field of optical storage technologies, and discloses a data read/write system and method. The method can be used to improve a read/write speed of optical storage without increasing a rotational speed of an optical storage medium. The system includes an optical deflector and a read/write optical head. The optical deflector is configured to sequentially deflect a first optical signal by a plurality of angles, to obtain a plurality of second optical signals. The read/write optical head is configured to receive the plurality of second optical signals, and separately focus the plurality of second optical signals on the optical storage medium, to implement reading/writing of a plurality of data points.
