    摘要： The present invention concerns to a method of recording and reproducing information. The information is recorded on and reproduced from a recording medium by use of two energy beams. The method is characterized in that shapes and areas of projection regions said two energy beams are substantially equalized on said recording medium, that one of said two energy beams is first projected on a predetermined position of that recording medium for bringing whole projection region into a fixed state and that the secon energy beam is subsequently projected on the predetermined position of said recording medium.
    A so called overwrite operation which records new information while erasing existent information ca be reliably performed in an information storage system such as optical disk system. In addiation it can be verified wether the rewriting of recording has been properly carried out.
