Abstract: The technology of this application relates to a data read/write apparatus and an electronic device, which relate to the data storage field, and can improve data read/write performance. The data read/write apparatus includes a first laser, configured to output a first optical pulse based on a control signal, where the control signal is a signal obtained based on to-be-written data, a dispersion compensator, configured to perform dispersion compensation on the first optical pulse to output a second optical pulse, and an optical fiber lens, connected to the dispersion compensator by using an optical fiber, and configured to focus the second optical pulse onto an optical storage medium, to write the to-be-written data to the optical storage medium.
