PURPOSE:To provide the large capacity magneto-optical recording and reproducing device having a high data transfer rate. CONSTITUTION:In the information recording and reproducing device enabling magnetic domain wall moving type overwrite, recorded data are reproduced by setting laser emitting power near a recording threshold value in the case of reproducing recorded information. Since reproduction beams have no inter-bit interference, even the data recorded with high density can be reproduced as well, and the capacity and the data transfer rate of the recording and reproducing device is improved. |
