摘要： In a method of recording and reading optical information in a recording medium using holography, a first recording operation is performed for recording optical information in a first recording region in an overlapping manner by allowing a reference beam and a signal beam with data loaded to interfere with each other in the first recording region, the reference beam being angularly multiplexed at predetermined intervals. Furthermore, a second recording operation is performed for recording optical information in a second recording region adjacent to the first recording region in an overlapping manner by allowing the reference beam and the signal beam to interfere with each other in the second recording region, the reference beam being angularly multiplexed between the predetermined intervals. Consequently, optical information can be recorded so as to easily detect and determine a selected reproducing beam, thus increasing the reading efficiency of the optical information.
