A ROM region provided by recording fixed information such as a book into a disk with pits by stamping and a RAM region formed by coating the disk with a magnetic film constitute a partial ROM magneto-optical disk medium. Additional information such as an underline and a note with respect to the fixed information is stored in the RAM region. A computer body reads the fixed information from the partial ROM magneto-optical disk medium by the operation of an operating portion, displays the information on a display unit, creates underline information and/or note information and a note mark, and displays such information on the display unit and, if necessary, stores it into the RAM region of the partial ROM magneto-optical disk medium. <IMAGE> |
