Description

technical field

[0001] The invention belongs to the technical fields of optical information storage and volume holographic data storage, and in particular relates to a method for compensating and correcting data errors generated by position errors during data readout. Background technique

[0002] With the advent of the information age, people's requirements for information storage, transmission and processing are increasing day by day. Optical information storage technology has become a new storage technology after magnetic storage technology due to its high density and long life, and has become the research object of all countries in the world. Optical volume holographic storage technology has become the most potential optical storage technology due to its advantages of high data redundancy, parallel data transmission, high storage density, fast addressing speed and related addressing functions. How to achieve a lower bit error rate in the readout process of the volume ho...
