When the partial ROM disk 1 is reproduced, the laser beam 12 is emitted with the reproduction power, and the data is reproduced with the reflected light. Further, when recording on the partial ROM disk 1, a laser beam 12 is emitted with a recording power, and a signal is recorded on the partial ROM disk 1.
[0021]
FIG. 3 is a block diagram of a computer system 20 that uses the partial ROM disk 1. This computer system 20 is a ROM 22 that is a read-only storage device that stores a BIOS or the like in the CPU 21, a RAM 23 that is a rewritable storage device that also serves as a work area for the CPU 21, and an external storage device for the computer system 20 The magnetic disk 24 and the optical disk drive 10 are connected by a bus 25.
[0022]
A computer program is recorded in the ROM area 2 of the partial ROM disk 1. This program includes a program for performing the following processing when the partial ROM disk 1 is loaded in the optical disk drive 10 and the computer system 20 reads the program recorded in the ROM area 2. Yes. Below, the content of this process is demonstrated with reference to the flowchart of FIG.
[0023]
That is, when the partial ROM disk 1 is loaded in the optical disk drive 10 and the program stored in the ROM area 2 is started, the CPU 21 has a function of recording the optical disk drive 10 in the recording / reproducing area 5 as described above. If it is recognized that the optical disc drive is not yet performed (N in step S1), the processing is terminated without starting the program stored in the ROM area 2.
[0024]
When the optical disk drive 10 recognizes that it has the function of performing recording in the recording / reproducing area 5 as described above (Y in step S1), the CPU 21 acquires an ID unique to the optical disk drive 10 (Specifically, an ID is recorded in a flash memory or the like mounted on the optical disk drive 10) (step S2), whether or not a stored ID exists in the recording / reproducing area 5 of the partial ROM disk 1 Is determined (step S3). When there is no stored ID in the recording / reproducing area 5 (N in step S3), the ID of the optical disk drive 10 obtained in step S2 is recorded in the recording / reproducing area 5 (step S6) and stored in the ROM area 2. The program is started normally (step S7), and the process is terminated.
[0025]
When there is a stored ID in the recording / playback area 5 (Y in step S3), it is determined whether or not this ID matches the ID of the optical disc drive 10 acquired in step S2 (step S4). If so (Y in step S4), the program stored in the ROM area 2 is normally started (step S7), and the process is terminated.
[0026]
If not, it is determined whether or not the number of IDs already recorded in the recording / reproducing area 5 is less than a predetermined number (step S5). If it is less than the predetermined number (Y in step S5), the ID of the optical disk drive 10 acquired in step S2 is recorded in the recording / reproducing area 5 (step S6), and the program stored in the ROM area 2 is recorded. It starts normally (step S7) and ends the process. When the predetermined number has been reached (N in step S5), the processing is terminated without starting the program stored in the ROM area 2.
[0027]
Through the processing as described above, the ID of the legitimate user's optical disk drive 10 is automatically recorded in the recording / reproducing area 5 (step S6), and whether this ID matches the ID of the current optical disk drive 10 or not. In step S4, it is automatically determined whether or not the partial ROM disk 1 is used by a legitimate user, and the program stored in the ROM area 2 is activated (step S7) or the activation is stopped. Therefore, it is possible to avoid the trouble of the user inputting the ID every time the partial ROM disk 1 is used, and to prevent unauthorized use of the partial ROM disk 1 even if the ID is known to others.
[0028]
Further, since the program stored in the ROM area 2 by the reproduction-only optical disc drive 10 having no recording function is disabled (N in Step S1), an ID unique to the optical disc drive 10 is recorded (Step S6). Without using the partial ROM disk 1, it is possible to prevent the optical disk drive 10 from being specified.
[0029]
Furthermore, since an ID different from the ID already recorded in the recording / reproducing area 5 can be additionally recorded in the recording / reproducing area 5 within a predetermined number of times (Y in step S5, step S6), there are a plurality of program license agreements. Can also respond.
[0030]
In this case, instead of enabling an ID different from the ID already recorded in the recording / reproducing area 5 to be added to the recording / reproducing area 5 within a predetermined number of times, a newly acquired optical disk drive 10 is obtained. The ID may be overwritten with the ID unique to the recording / reproducing area 5 as necessary. Thereby, it is possible to cope with a change in the usage environment of the authorized user such as a change of the computer system 20 using the partial ROM disk 1.
