8. A data processing method for a system, the method comprising:

recording a plurality of stroke data comprising information concerning loci handwritten on a screen and information concerning a time when loci are handwritten on the screen, the stroke data being associated with document files which are displayed on the screen when loci are handwritten on the screen; and

executing data processing for associating a first document file and a second document file using both a first time comprised in first stroke data associated with the first document file and a second time comprised in second stroke data associated with the second document file, wherein loci of the first stroke data are handwritten on the first document displayed on the screen at the first time, and loci of the second stroke data are handwritten on the second document displayed on the screen at the second time, wherein the first document and second document are linked based on the recorded time of each stroke data of the loci.

9. A computer-readable, non-transitory storage medium having stored thereon a computer program which is executable by a computer, the computer program controlling the computer to function as:

a recorder to record a plurality of stroke data comprising information concerning loci handwritten on a screen and information concerning a time when loci are handwritten on the screen, the stroke data being associated with document files which are displayed on the screen when loci are handwritten on the screen; and

a processing circuitry to execute data processing for associating a first document file and a second document file using both a first time comprised in first stroke data associated with the first document file and a second time comprised in second stroke data associated with the second document file, wherein loci of the first stroke data are handwritten on the first document displayed on the screen at the first time, and loci of the second stroke data are handwritten on the second document displayed on the screen at the second time, wherein the first document and second document are linked based on the recorded time of each stroke data of the loci.

10. The method of claim 8 , wherein the executing comprises:

displaying first loci indicated by the plurality of stroke data on the screen;

recognizing either a character or graphic represented by loci indicated by the plurality of stroke data; and

displaying second loci indicated by the plurality of stroke data on the screen in a format different from a format of the first display module, by using a recognition result by the recognizing and the times indicated by the stroke data.

11. The method of claim 10 , wherein the displaying the second loci comprises processing, if the recognizing recognizes a graphic for designating a region, a character string recognized by the recognizing and included in the region designated by the graphic as one object, and executing data processing to loci indicated by the plurality of stroke data in units of object.

12. The method of claim 8 , wherein:

the recording comprises recording the plurality of stroke data for each user; and

the executing comprises superimposing loci indicated by the plurality of stroke data recorded for each user, by using the times indicated by the plurality of stroke data.

13. The method of claim 12 , wherein:

the recording comprises recording the plurality of stroke data in association with data displayed on the screen when a handwriting operation is performed on the screen; and

the executing comprises combining loci indicated by the plurality of stroke data superimposed by the superimposing with the data associated with the plurality of stroke data, and to display the obtained data on the screen.

14. The method of claim 12 , wherein the superimposing comprises superimposing loci indicated by the plurality of stroke data in a time serial manner.

15. The method of claim 12 , wherein the superimposing comprises accepting user designation, and superimposing loci of the designated user.

16. The medium of claim 9 , the processing circuitry to execute:

displaying first loci indicated by the plurality of stroke data on the screen;

recognizing either a character or graphic represented by loci indicated by the plurality of stroke data; and
