Classification: CPC nan | IPC G

Claim 12:
13. A data read/write apparatus, comprising:
a first laser;
a dispersion compensator;
a first optical fiber coupler;
N optical switches;
an N-channel photoelectric controller; and
N optical fiber lenses, wherein
the first optical fiber coupler is connected to the N optical switches by using optical fibers, the N-channel photoelectric controller is connected to the N optical switches separately, the N optical switches are correspondingly connected to the N optical fiber lenses by using the optical fibers, and N is a positive integer greater than or equal to 2,
the first laser is configured to output a first optical pulse,
the dispersion compensator is configured to perform dispersion compensation on the first optical pulse to output a second optical pulse,
the first optical fiber coupler is connected to the dispersion compensator by using an optical fiber, and the first optical fiber coupler is configured to split the second optical pulse into N beams of optical pulses,
the N-channel photoelectric controller is configured to control states of the N optical switches based on N control signals thereby adjusting light intensity of the N beams of optical pulses, wherein the N control signals are respectively obtained based on N pieces of to-be-written data, and the N beams of optical pulses indicate the N pieces of to-be-written data, and
the N optical fiber lenses are configured to focus the N beams of optical pulses onto an optical storage medium thereby writing the N pieces of to-be-written data to the optical storage medium, wherein the N optical fiber lenses are in one-to-one correspondences with the N beams of optical pulses.
