PURPOSE:To preserve modification information of underlines, contents correction, etc., of fixedly stored information by providing a magneto-optical recorder and reader instead of a CD-ROM driver. CONSTITUTION:A microcomputer 12 performs the processing according with the input and outputs the result to an LCD driver 22 and a magneto-optical recording and reproducing device 8. This device 8 is controlled through an I/O interface 20 by a CPU 14 as a constituting element of the microcomputer 12. The device 8 reads out data in a hybrid disk to send it to the CPU 15 at the time of the read indication from the CPU 14 and records data in an area for read and write of the hybrid disk at the time of receiving a write instruction from the CPU 14. Thus, modification information of underlines, contents change, etc., of information recorded in a read-only area of a disk information recording medium can be written and preserved in the area for read and write of the disk recording medium. |
