Abstract

Disclosed herein is an information processing apparatus capable of storing therein modifier information such as an underline, a correction of contents, etc. with respect to fixed and stored information. A microcomputer effects processing corresponding to an input and outputs information indicative of the result of processing therefrom. An optical magnetic recording and reproducing device records the information indicative of the result of this processing, which has been outputted from the microcomputer, on a read/write area of a hybrid disc.

Claims

1. An information processing apparatus comprising:

inputting means for inputting of information from an operator by handwriting;

processing means for effecting processing on the handwritten information input by the operator and for outputting holograph information corresponding to the handwritten information; and

recording and reproducing means for recording information on and reproducing the information from a disc recording medium having a read-only area with predetermined information recorded thereon in advance and a read/write area for storing therein the holograph information.

2. An information processing apparatus as claimed in claim 1, further comprising displaying means for displaying the holograph information.

3. An information processing apparatus according to claim 1, wherein the inputting means comprises a pressure sensitive tablet.

4. An information recording apparatus according to claim 1, wherein the recording and reproducing means reproduces information from the read-only area of the disc recording medium by using a diffraction phenomenon of light rejected from the read-only area.

5. An information processing apparatus for use with a hybrid disc having a read-only area and a read/write area, the information processing apparatus comprising:

a processing unit;

a recording and reproducing unit for reproducing read-only data from the read-only area of the disc and for sending the read-only data to the processing unit;

a display for receiving at least the read-only data from the processing unit and for displaying at least the read-only data; and

an input means for inputting of coordinate data from a user by handwriting and for sending the coordinate data to the processing unit;

wherein the processing unit has means for processing the coordinate data to generate modifier data which represents a holograph corresponding to the coordinate data, the processing unit sends the modifier data to the recording and reproducing unit, and the recording and reproducing means has means for writing the modifier information to the read/write area of the disc.

6. The information processing apparatus according to claim 5, wherein the input means is disposed over the display.

7. The information processing apparatus according to claim 5, wherein the input means is a pressure sensitive tablet which receives the coordinate data corresponding to pressure from the user'"'"'s finger or a pen.

8. The information processing apparatus according to claim 5, wherein the recording and reproducing unit has means for reproducing the read-only data from the read-only area of the disc by a diffraction phenomenon of light reflected from the read-only area of the disc.

9. The information processing apparatus according to claim 5, wherein the display has means for receiving the coordinate data from the processing unit and for displaying the coordinate data.

10. The information processing apparatus according to claim 5, wherein the display has means for receiving the modifier data from the processing unit and for displaying the modifier data.

11. The information processing apparatus according to claim 5, wherein the recording and reproducing unit has means for reproducing modifier data from the read/write area of the disc and for sending the modifier data to the processing unit, the processing unit has means for sending the modifier data to the display, and the display has means for displaying the modifier data reproduced from the read/write area of the disc.

12. The information processing apparatus according to claim 5, wherein the processing unit comprises a processing means and a random access memory (RAM).

13. The information processing apparatus of claim 12, wherein the input means has means for sending the coordinate data to the processing unit at predetermined travel distances, and the processing unit has means for storing the coordinate data sent from the input means to the processing unit in a temporary work area in the RAM of the processing unit as coordinate string data.

14. The information processing apparatus according to claim 5, wherein the processing unit has means for determining whether inputting of coordinate data from a user has been completed.

15. The information processing apparatus according to claim 5, wherein the coordinate data input from the user represents coordinates defined with reference to an X axis and an orthogonal Y axis.
