Embodiment Construction
[0064] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations.
[0065] The terms "first" and "second" in the description and claims of the embodiments of the present application are used to distinguish different objects, rather than to describe a specific order of objects. For example, the first light pulse and the second light pulse are used to distinguish different light pulses, not to describe the specific sequence of light pulses, and the first laser and second laser are used to distinguish different lasers, not Used to describe a specific sequence of lasers.
[0066] In the embodiments of the present application, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design scheme describe...

Abstract
The embodiment of the invention provides a data read-write device and electronic equipment, relates to the field of data storage, and can improve data read-write performance. The data read-write device comprises a first laser used for outputting a first optical pulse according to a control signal, and the control signal is a signal obtained according to data to be written; the dispersion compensator is used for performing dispersion compensation on the first optical pulse to output a second optical pulse; and the optical fiber lens is connected with the dispersion compensator through an optical fiber and is used for focusing the second optical pulse to the optical storage medium so as to write the to-be-written data into the optical storage medium.
Description
technical field [0001] The embodiments of the present application relate to the field of data storage, and in particular to a data reading and writing device and electronic equipment. Background technique [0002] Optical storage technology has the advantages of energy saving and long service life. Using optical storage technology, data can be written into or read from an optical disc. [0003] At present, data writing and reading is achieved by changing the optical path of the laser through optical components (including mirrors, objective lenses, etc.), because optical components are sensitive to external factors such as dust and humidity, and are easy to The occurrence of optical path imbalance will affect the reading and writing of data, resulting in a decrease in the performance of reading and writing data. Contents of the invention [0004] The embodiments of the present application provide a data reading and writing device and electronic equipment, which can improve...
