Abstract

An information processing apparatus and method operate using a removable medium such as a removable disk on which all necessary software and content are recorded. The information processing apparatus includes a removable disk drive for recording and reproducing an information signal onto or from the removable disk, a main memory and a flash memory for storing information, and a central processing unit (CPU) for controlling the above-described parts such that when the removable disk is inserted into the removable disk drive, software is automatically loaded into the main memory and executed, necessary information is recorded on the removable disk, and, if the execution of the software is ended, the removable disk is ejected. An information processing apparatus based on this single medium activated platform (SMAP) architecture may serve as various devices depending on the application program or software that is stored on the removable disk. Thus, the information processing apparatus can be used easily by any user, even by one who does not have knowledge about computers.

Claims

1. An information processing apparatus using a storage medium storing all software and content required in processing performed by said information processing apparatus, said information processing apparatus comprising:

recording and reproducing means for recording and reproducing an information signal onto and from said storage medium;

storage means for storing information; and

control means for controlling each of said means;

wherein said control means controls said recording and reproducing means and said storage means such that;

when said storage medium is inserted into said information processing apparatus, all necessary software and content required in processing by said information processing apparatus are loaded into said storage means from said storage medium via said recording and reproducing means, and said software is executed; and

said storage medium stores all execution results and associated data and is ejected after completion of the execution of said software.

2. An information processing apparatus according to claim 1, wherein said control means reads hardware identification information stored on said storage means of the information processing apparatus and determines the compatibility between hardware of said information processing apparatus and said storage medium.

3. An information processing apparatus according to claim 1, wherein said storage medium is a rewritable storage medium.

4. An information processing apparatus according to claim 1, wherein said storage medium is a storage medium including a rewritable part and a read-only part.

5. An information processing apparatus according to claim 1, wherein said storage medium is a read-only storage medium.

6. An information processing apparatus according to claim 1, further comprising a second recording and reproducing means for recording and reproducing information onto and from a second storage medium, wherein said control means controls said second recording and reproducing means in a manner similar to said recording and reproducing means.

7. An information processing apparatus according to claim 6, wherein only when both storage media include their own identification and the identification of one storage medium is equal to that of the other storage medium, said control means allows data stored in an area other than a pre-mastered area of said one storage medium to be transferred to an area other than a pre-mastered area of said other storage medium.

8. An information processing apparatus according to claim 1, wherein when said storage medium is inserted into said information processing apparatus, said control means loads, in accordance with a program stored on said storage medium, a loader program for loading all necessary software and content from said storage medium into said storage means, and also loads loading control information used to control the operation of loading the necessary software and content from said storage medium into said storage means.

9. An information processing apparatus according to claim 8, wherein when said storage medium is a rewritable medium or a medium including a rewritable part and a read-only part, information including at least one of system information, error information, information indicating the number of times said storage medium has been used, and date information, is recorded in a predetermined area of said storage medium when the execution of the software ends.

10. An information processing apparatus according to claim 8, wherein:

said loading control information includes management information associated with said storage medium; and

said control means stores the number of times said storage medium has been used on said storage medium, and controls the number of times said storage medium is used by comparing said management information with the number of times stored.

11. An information processing apparatus according to claim 8, wherein:

said loading control information includes identifications assigned to respective segments of said storage medium, said software being divided into a plurality of parts which are stored in the respective segments, each identification indicating the attribute of a respective segment; and

wherein software is loaded from said storage medium in accordance with said loader program and said identifications.

12. An information processing apparatus according to claim 11, wherein when said storage means includes a nonvolatile storage area, said control means determines, in the process of loading software from said storage medium, whether the identification of a segment of the storage medium is equal to the identification indicating the attribute of the corresponding segment of the software stored in said nonvolatile storage area, and skips that segment if the identifications are equal to each other.

13. An information processing method using a storage medium for storing all software and content required in processing performed by an information processing apparatus, said method comprising the steps of:

recording and reproducing an information signal onto and from said storage medium;

controlling said recording and reproducing step such that,

when said storage medium is inserted into said information processing apparatus, all necessary software and content required in processing by said information processing apparatus are loaded from said storage medium into a storage means in said apparatus and said software is executed; and

storing all execution results and associated data on said storage medium and ejecting said storage medium after completion of the execution of said software.

14. An information processing method according to claim 13, further comprising a second recording and reproducing step for recording information on a second removable storage medium.

15. An information processing method using a storage medium for storing information in an information processing apparatus, said storage medium storing all software and content required in processing performed by said information processing apparatus, said information stored on said storage medium including at least one of a device driver, an operating system, and an application, said method including the steps of:

recording and reproducing an information signal onto and from said storage medium;

storing information into a storage means of said information processing apparatus; and

controlling the recording and reproducing step and the storing step described above such that when said storage medium is inserted into said information processing apparatus, all necessary software and content required in processing by said information processing apparatus are loaded into said storage means from said storage medium and said software is executed, and said storage medium stores all execution results and associated data and is ejected after completion of the execution of said software.

16. The method according to claim 15, further comprising a step of recording information on a second removable storage medium.

17. The method according to claim 15, wherein when said storage medium includes at least one rewritable part, information including at least one of system information, error information, information indicating the number of times said storage medium has been used, and date information, is recorded in a predetermined area of said storage medium when the execution of the software ends.
