Abstract
Abstract 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
45 words
A partial ROM magneto-optical disk medium comprising: a ROM region exclusively for reading into which fixed information is recorded by stamping; and a rewritable RAM region for storing at least additional information such as an underline and a note with respect to said fixed information.
Claim 2
Dependent Claim
32 words
A partial ROM magneto-optical disk medium according to Claim 1, wherein said fixed information is a book such as a dictionary, a manual, a reference book and a dictionary of technical terms.
Claim 3
Dependent Claim
39 words
A partial ROM magneto-optical disk medium according to Claim 1, wherein said additional information is modifying information such as an underline and has data which indicates the position of said fixed information at which said fixed information is modified.
Claim 4
Dependent Claim
49 words
A partial ROM magneto-optical disk medium according to Claim 1, wherein said additional information is note information such as a note for the word or the phrase in said fixed information to which a note mark is added and has data which indicates the position of the note mark.
Claim 5
Dependent Claim
128 words
A computer system comprising: a partial ROM magneto-optical disk apparatus using as a storage medium a partial ROM magneto-optical disk medium provided with ROM region for storing fixed information and a readable/rewritable RAM region for storing additional information such as an underline and a note with respect to said fixed information; a display unit for displaying said fixed information and said additional information such as an underline and a note ; an operating portion which is operated so as to create said additional information such as an underline and a note and to display said additional information; and a control unit for creating said additional information such as an underline and a note and displaying said additional information on the basis of the operation of said operating portion.
