Set the pit in area 15 of the trademark image is performed so as to be visually recognizable as the desired shape with a bottom surface 34, which is the surface of the optical detection.

Method for the formation of the subject to compare the data And using the pit will be explained with reference to Fig.6A-6C.

Want to compare the data And, for example, "SG formed in the set of pits, as shown in Fig.6A. Want to compare the data And visible (visually recognizable as a sign of "SG") from the bottom surface 34 to the surface of the optical detection of the disk substrate 31, as shown in Fig.5.

Each point forming the letter "SEGA", contains a set of arrays of pits, oblast, dashed And formed in one visible point 70 of the longitudinal tracks and 12 transverse arrays of pits. For example, arrays In the pit provides the block on which the coating patami zone the maximum, as shown in Fig.6C(A), and arrays With pits provide the block on which the coating patami zone is made minimum, as shown in Fig.6C(B).

Such points are located in the required locations for the formation of letters. Letters, such as "SEGA" in Fig.6A, is formed in the region 15 denote the trademark, determined essentially by 1000 tracks.

In Fig.6A-6C symbol in a predetermined region 15 of the disk substrate 31 formed visible (readable or recognizable) as letters from the bottom surface 34, which is the surface of the optical detection (see Fig. 5), but can be formed visible from the upper surface 38 opposite to the surface of the optical detection (see Fig.5). In Fig.5, it is possible that the protective layer 37 is formed of a transparent material so that the special symbol may be visible from the outer surface 38.

As shown in Fig. 2, the gaming machine 10 includes a reading unit 17. The block 17 is connected to the optical the BOJ block 18 detection information and the block 19 comparison. Block 18 detection information includes circuit 20 generating random numbers, which functions as the unit of selection.

Block 18 detection information controls provisions of reading the optical head 16 play relatively ROM-KD 12 and generates output signals (a) detection, giving commands to the optical playback head to read the special tracks that are located in region 15 a trademark notice and are subject to comparison. Special tracks are randomly selected from a group of tracks, which consist of arrays of pits forming the compared data A. the Choice is determined by a random number generated by the circuit 20 generating random numbers.

That is, the optical head 16 playback selects and reads a special arrays of pits, which are special information composed of arrays of pits, which indicate the block group information.

Information (in) array of pits, a few special tracks, served on the block 19 comparison.

Special tracks that should be read by the optical head 16 playback can be obtained by selecting multiple blocks, in which one to whom ojek defined as a block.

Unit 19 comparison stores main data D (see Fig.8) as digital signals in a semiconductor ROM. The main data D are reference information or standard information to decide whether data A. Basic data D correspond to the reference designation as a special designation "SEGA", as shown in Fig.8. Digital reference data corresponding to the special symbol "SEGA", are stored in a semiconductor ROM, in which the reference block is a set of data associated with each path consisting of a set of pits. Special designation And formed on the disk ROM-KD, as the same group of pits, and the reference symbol D. Subject than a special designation And is detected on the selected tracks, in which the comparing unit is the corresponding track, consisting of a set of pits.

When a comparison is found to be the comparison data and the reference data D coincide with each other, a decision is made that a special designation identified in the field, and when the comparison is found to be the comparison data and the reference data D do not coincide with each other, a decision on amative information (C) the comparison result as the comparison result.

That is, the block 19 comparison functions as a store of fixed or reference data corresponding to the special symbol D; as an output unit for comparing subject comparison data indicating information compare array pits special designations And reference data, and to generate the output signal based on the comparison result, and as a crucial block to make decisions about presents or no special designation.

Next, the operation of the read unit 17 will be explained with sipkema on the block diagram of the algorithm of Fig.9.

The gaming machine 10 is turned on to start the scanning operation.

First block 18 detection information defines a special track to be compared (operation S1). Subject comparison special paths for data And defined as, for example, Track 1, Track 2, etc. corresponding to the random numbers generated by the circuit 20 generating random numbers. Track numbers corresponding to a predetermined number of tracks are randomly selected.

Then the part of the subject to compare the data read by the optical head 16 playing with ROM-KD 12, which is scanned by the media (the op is for reading information from arrays of pits special tracks.

Following this, the read data and the reference data are compared with each other (operation S3). The information read from the arrays of pits, and the reference data D is compared with the block 19 comparison.

Then the block 19 comparison makes the decision are the same or not between these data (operation S4). When the block 19 comparison detects a mismatch between the read information and the reference information unit 19 decides "NO", and performs error handling (operation S5). And the verification operation ends.

On the other hand, when the read information and the reference information coincide with each other, the unit 19 decides "YES" and decides all or not all the data defined in the operation I compared (operation S6).

The decision "YES" is made after comparing all the data that should be compared, then the comparison operation is terminated. The decision "NO" is made, respectively, if all comparison operations are not yet completed, then return to operation S2 to be read comparison data. This operation is repeated until such time as all verifiable information will not be compared and while it is not made a decision.

When both information coincide the two data do not coincide with each other, block 18 detection information cannot read the information area program 14 program or stops the game.

In the above operation, check the number under test paths are selected for each verification operation and simultaneously with the select track numbers the number of eligible test track is subject to inspection data may vary for each comparison operation.

Thus, the retrieving unit 17 selects randomly be compared are special tracks from the group of tracks without checking all the tracks, so the inspection can be carried out in a short period of time. Moreover, such a shortened scan time allows more data more tracks or more images to be set as a subject to compare data And that improves the protective effect.

So as to be comparing lane change at the beginning of each test subject comparison data And stored in ROM-KD 12, as in to be verified or the carrier shall be full of data, that is, the complete image. In addition, there is possible a more accurate check by changing the number of special Dor is right for the electronic device or an information processing authentic gaming machine or other, you want to put in a pre-specified location ROM-KD developed a special designation as subject to comparison data And corresponding to the main data D as the reference or the reference information stored in an authentic electronic device or the information processing unit. If he does, he will be legally charged with copyright infringement.

Examples of special designations are trademark, logo and brand name that is protected by the Law on trademarks and industrial design, sign, image, and so on, are protected by the Law on industrial designs. Industrial designs, trademarks, images, etc. are protected in some States Patent law and the Law on industrial designs, copyright, etc.

Reference data D are subjected to the processing of data compression to reduce the amount of data, so reading unit 17 takes up less space and reduces cost.

In the above-described variant embodiments area for special designations to be verified on the protection of the ROM-KD is not limited to the position shown in Fig.3, and is subject to change.

As shown in Fig. 10B, the area 15V, on which no recorded information of the game program, defined outside area 14 program area for recording information along the outer circumference of the disk, and the region 15 for application of the special symbols with a set of pits may be formed in the zone of 15V.

That is, these zones 15A, 15C defined as a formation zone designations on the parts other than the recording area information, and the region 15 is defined as an area designations in the area 15A or 15C.

In the variant of Fig. 10C many areas 15 may be formed continuously or at certain intervals in the zone of 15V. This special designation may be placed in the respective fields 15 or two different signs may be placed alternately in the respective areas 15.

In this version these areas 15 can be randomly selected as the subject to compare the data And to test many areas 15 on the basis of random numbers generated by the circuit 20 generating random numbers. The combination of regions 15 in the regulations randomly selected, and the selected SL is she 15V can be performed from outside the area 14C read ROM-KD 12, so the area 15V can be installed completely separately from the store information area 14 of the program, so the control for reading information and to detect special characters can be facilitated.

In the area 15V as shown in Fig.10D, the image of the TRADE MARK' SEGA (the"Trademark "SEGA", "PRODUCED BY or UNDER LICENSE FROM SEGA ENTERPRISES, LTD." Produced by SEGA ENTERPRISES, LTD. or her license") is formed by sets of the pit.

As a special designation for the above security check in addition to the various letters, drawings, etc. can be used are registered trademarks, registered designs, designs, such as symbols, etc. that are protected by copyrights, trade names, signs, symbols, used industrial groups, etc., if they are identifiable to really the only. That is, it is preferable that the reference designation was able to prevent do not have the right person to put the same designation. Reference designation may belong to any one group or its use may be granted under the license agreement. Can be used a large number of these same signs or can be used Societatea formed a visible size and shape and can be made in the sector along the edge of the ROM-KD 12.

Carrier has additional free space, necessary for skipping sectors remaining at the end of zone during sliding replacement process.

EFFECT: higher efficiency.
