Below, use description of drawings example of the present invention.
Fig. 1 is the principle pie graph of a routine optical disc apparatus of the present invention.
When CD 4 was inserted the CD gateway 23 of optical disc apparatus 20, CD 4 was sent to CD drive 21, carried out recording of information, regeneration or wiped.And then, come the exchange of display disc and depositing of dish by operation board alteration switch or telechiric device, thus, CD 4 comes out and leaves in the interchanger 22 from CD drive 21.Interchanger 22 has been deposited many CDs, CD 4 can be sent to CD drive 21, perhaps deposits the CD of sending out from CD drive 21 4.Having, also can be the structure of carrying out the direct transmission of CD 4 between CD gateway 23 and interchanger 22 again.In addition, be used for carrying out the information signal input and output portion 24 of message exchange, can be recorded in various information in the CD 4 and be used with external device (ED) by equipment.
Fig. 2 is the summary pie graph of the routine CD drive 21 that illustrated at Fig. 1.CD 4 rotates because of the driving of driving mechanism 14.Shaven head 10 is driven by bare headed drive unit 12 and is moved on the desired track of CD 4.Shaven head 10 also with the relative position relation of CD 4 is corresponding is sent to electronic circuit 11 with focus error signal and tracking error signal.Electronic circuit 11 is corresponding with this signal sends the signal that is used for making the object lens fine motion to shaven head 10.Shaven head 10 carries out focus servo control and tracking servo control according to this signal to CD 4, and CD 4 is carried out reading, write or wiping of information.Have again, the 13rd, with the power supply in the optical disc apparatus 20 or the connecting portion of external power source, the 15th, the cabling that the electronic circuit of electronic circuit 11 and optical disc apparatus 20 is connected.
Below, be example with Fig. 1, optical disc apparatus shown in Figure 2, specifically describe the example of information recording/reproducing apparatus of the present invention.
(example I)
The process flow diagram of the action when Fig. 3 is expression optical disc apparatus taking-up of the present invention CD.
When the user requires the CD in CD drive 21 or the interchanger 22 when take out the outside (step 30) by push switch or operating and remote controlling device methods such as (being omitted in Fig. 1), differentiate optical disc apparatus 20 and whether can carry out the taking-up (taking out) (step 31) of CD, here, have only when being judged as just to allow can take out (YES) time CD is taken out, the user take out CD (step 32) under the state of the indication that is obtaining CD to be taken out to the outside.When being judged as to take out (NO) time, then refusal takes out (step 33), preferably send error message (at this moment, though it is not shown, but optical disc apparatus 20 also possesses display device) or warning sound (at this moment, though not shown, optical disc apparatus 20 possesses loudspeaker), notify the user, cannot take out CD (step 34).
Fig. 4 be illustrating of Fig. 3 process flow diagram in enumerate the figure that several states according to CD judge whether to take out the judgment standard of CD (step 31) particularly.Below, they are described.
(example I-1)
The method of discrimination of the compact disc states of example I-1 (could take out) is, is that recordable CD then is judged as and can not takes out (NO) if receive this CD that will seek out, and can take out (YES) if the regeneration special-purpose cd then is judged as.
Here, be the method for discrimination of recordable CD or regeneration special-purpose cd as the CD of differentiating object, for example can be then to be judged as recordable CD in the time of in CD is contained in chuck, perhaps according to judging from shaven head 10 signals that obtain.
When according to from shaven head 10 signals that obtain when judging, for example, be judged as CD-R in the time of a little less than the signal intensity ratio setting, when hanging down with respect to the amplitude ratio (degree of modulation) of time-averaged signal intensity, high-frequency signal is judged as CD-R, depart from and the feature of the focal point control signal of shaven head 10 object lens that possess when moving is differentiated according to focal point control, perhaps from the combination of these methods, go the kind of judgement dish.
If according to this example, can record the information on the recordable CD, be used for the individual and appreciate.Simultaneously, owing to forbid the taking-up of CD-R, so, concerning the literary property owner, need not just can realize the protection of literary property through any disposal.
(example I-2)
The method of discrimination of the compact disc states of example I-2 (could take out) is, at first, when the information of obtaining from the outside by information signal input and output portion 24 waits the information record that carries out CD, the expression CD has been write down in the nonvolatile memory (omitting among Fig. 1) of recording of information placement file in optical disc apparatus 20.
On the other hand, when receiving the requirement of taking-up CD, confirm the record resume of relevant this CD in the storer.Then,, then be judged as and take out (NO),, then be judged as and take out (YES) if there are not such record resume if exist the expression CD to write down the recording of information resume.
The record resume here can be stored by CD by corresponding storer that comes the stored record resume of the address sequence number of the interchanger 22 that is provided for and deposits CD etc.
If according to this example, can record the information on the recordable CD, be used for the individual and appreciate.Simultaneously,, for example can replace the different CD of capacity etc. if Unrecorded CD then can take out, just but in a single day forbid taking out behind the record, so, concerning the literary property owner, need not just can realize the protection of literary property through any disposal.
(example I-3)
The method of discrimination of the compact disc states of example I-3 (could take out) is as follows.
When the information of obtaining from the outside by information signal input and output portion 24 waits the information record that carries out CD, judge information (for example, music information, image information, database information etc. to writing down.Sometimes also be referred to as ' content information ' below) whether added expression is necessary to protect its literary property to this information signal (below, also only be called ' copyright protection signal ' sometimes).When not adding this signal, then intactly content information is recorded on the CD.On the other hand; when having added this signal; when being recorded in content information on the CD; expression is recorded in record resume on the CD to the information that is necessary to protect literary property (below, also only be called ' copyright protection object information ' sometimes) to be stored in the nonvolatile memory of optical disc apparatus 20 (omitting among Fig. 1).
When receiving when taking out the requiring of CD, confirm the record resume of relevant this CD in the storer.Then,, then be judged as and take out (NO),, then be judged as and take out (YES) if there are not such record resume if exist this CD of expression to write down the record resume of copyright protection object information.
The record resume here can be stored by CD by corresponding storer that comes the stored record resume of the address sequence number of the interchanger 22 that is provided for and deposits CD etc.
In addition, the originator of this information judges whether to be necessary to protect the literary property of information one by one, and when being judged as when being necessary to carry out copyright protection, the originator of this information rule according to the rules is attached to the copyright protection signal on this information and gets final product.For example, when being recorded in the copyright protection object information on the CD and sending,, just can add the copyright protection signal by only the specific part of CD being given the extremely low physical characteristics that waits of reflectivity of information recording surface.Perhaps; when radiolinks such as broadcasting via satellite send the copyright protection object information; by using specific frequency and ripple segment number; can discern the content information that is sent and be copyright protection object information (at this moment, the specific frequency and the use of ripple segment number are equivalent to add the copyright protection signal).
If according to this example, information (copyright protection object information) can be recorded on the recordable CD, be used for the individual and appreciate.And, to there is no need to carry out the information of copyright protection, for example, if the family that user oneself takes picture recording images etc. can freely duplicate and/or edit, and CD is passed on other people.On the other hand; when the originator of information wishes to protect the literary property of this information; then as long as just can forbid that by behind additional copyright protection signal, sending information again the CD that will write down this information takes out; so; concerning the literary property owner, after sending, information need not just can realize the protection of literary property through any disposal.
(example I-4)
This example is; in above-mentioned example 1-3; even at the copyright protection signal that will record additional relevant this information in content information back on the CD; not intactly to write down this information but this quality of information is reduced under the situation about writing down more than the required standard; when the taking-up that receives this CD requires, be judged as and take out (YES).
For example, when reducing quality of information and write down, above-mentioned storer not storage representation has been recorded in the copyright protection object information record resume on the CD.Perhaps, above-mentioned memory stores is represented with the record resume that write down again after the quality of information reduction.When the taking-up that receives this CD requires, confirm the record resume of relevant this CD in the storer.Then, if there is not expression the copyright protection object information to be recorded in record resume on this CD, the record resume that write down again after perhaps having expression quality of information to be reduced then are judged as and can take out (YES).When being not both of these case, then being judged as and taking out (NO).
Above-mentioned what is called reduces information quality, if music information or image information refer to, for example reduce sampling rate (sample frequency), the recording frequency band width is limited in the small range, perhaps, the low frequency bandwidth is compressed to necessary degree, perhaps, the passage figure place of the signal magnitude in a certain moment (is for example reduced, 16 2 system signals are become 8 signal), thus resolution (compression of dynamic range) reduced, reduce tonequality or picture quality.In addition, if information such as database refer to, for example destroy wherein part and parcel.
Have again, because of the different differences that produce the reduction degree of method that reduce information quality.Which type of degree is is can does quality reduced to and just judged as CD and take out actually? this point can be set arbitrarily.Therefore,, then be judged as not decline of quality in fact if quality only descends a little, still can be with it as the copyright protection object.The sender of for example, copyright protection object information can drop to information quality actually the content what degree just calculates outside the copyright protection object and note with the copyright protection signal.For such situation,, just be judged as and take out CD as long as information quality is reduced to more than the degree of defined.Therefore, can realize the desirable copyright administration of literary property owner.
If according to this example, for the copyright protection object information, reduce quality of information as condition with appropriateness, can relax restriction to the diffusion of Copy Info, take into account the protection of literary property and the convenience that information is utilized.
(example I-5)
This example is; according to above-mentioned example 1-3; even will add the information of copyright protection signal is recorded on the CD; and the record resume that will represent to write down the copyright protection object information are stored in the storer; the quality that is recorded in this copyright protection object information on the CD is reduced under the situation more than the required standard; when the taking-up that receives this CD requires, be judged as and take out (YES).
For example, when for having expression when having write down the CD of record resume of copyright protection object information and having carried out making the operation that quality of information reduces, just delete this record resume.Perhaps, expression has been carried out make the record resume of the operation that quality of information reduces to be stored in the above-mentioned storer.When the taking-up that receives this CD requires, confirm the record resume of relevant this CD in the storer.Then,, perhaps there is expression to carry out the record resume of operation that quality of information is reduced, then is judged as and takes out (YES) if there is not expression the copyright protection object information to be recorded in record resume on this CD.When being not both of these case, then being judged as and taking out (NO).
The operation of above-mentioned reduction information quality refers to, and content information carries out the operation that example 1-4 had illustrated on the CD to being recorded in, and this quality of information is reduced.After having carried out such operation, there is not information (the operation information before that quality of information is reduced) originally in CD.
This example produces the differences of reduction degree too because of the method difference that reduces information quality.Which type of degree is is can does quality reduced to and just judged as CD and take out actually? this point can be set arbitrarily.Therefore,, then be judged as not decline of quality in fact if quality only descends a little, still can be with it as the copyright protection object.For example, I-4 is the same with example, and the sender of copyright protection object information can drop to information quality actually the content what degree just calculates outside the copyright protection object and note with the copyright protection signal.For such situation,, just be judged as and take out CD as long as information quality is reduced to more than the degree of defined.Therefore, can realize the desirable copyright administration of literary property owner.
If according to this example, information (copyright protection object information) can be recorded on the recordable CD, be used for the individual and appreciate.And, to there is no need to carry out the information of copyright protection, for example, if the family that user oneself takes picture recording images etc. can freely duplicate and/or edit, and CD is passed on other people.On the other hand,, reduce quality of information as condition, can relax restriction, take into account the protection of literary property and the convenience that information is utilized the diffusion of Copy Info with appropriateness for the copyright protection object information.
(example I-6)
This example is; according to above-mentioned example 1-3; even will add the information of copyright protection signal is recorded on the CD; and the record resume that will represent to write down the copyright protection object information are stored in the storer; in the information of the necessity that has been recorded in this copyright protection object information on the CD of being used to regenerate by deletion (for example; be recorded in management information on the CD etc.; claim ' regenerating information ' below) make under the unrenewable without exception situation of this copyright protection object information; when the taking-up that receives this CD requires, be judged as and take out (YES).
For example, when for having expression when having write down the CD of record resume of copyright protection object information and having carried out the operation of deletion regenerating information, just delete this record resume.Perhaps, the record resume that expression carried out the operation of deletion regenerating information are stored in the above-mentioned storer.When the taking-up that receives this CD requires, confirm the record resume of relevant this CD in the storer.Then,, perhaps there is expression to carry out the record resume of the operation of deletion regenerating information, then is judged as and takes out (YES) if there is not expression the copyright protection object information to be recorded in record resume on this CD.When being not both of these case, then being judged as and taking out (NO).
Have again, needn't the Delete All regenerating information, as long as the copyright protection object information can not be regenerated, also can delete the part of regenerating information.
If according to this example, information (copyright protection object information) can be recorded on the recordable CD, be used for the individual and appreciate.In addition; for 1 video disc recording copyright protection object information and information in addition (for example; information such as family's picture recording image that user oneself takes) situation; as long as only delete the shirtsleeve operation of the regenerating information (not being the copyright protection object information) of this copyright protection object information, just can promptly CD be taken out.For example, when interchanger 22 is taken,, just new CD can be changed, improve operating performance by deleting the regenerating information of unwanted copyright protection object information.
(example I-7)
This example is; according to above-mentioned example 1-3; even will add the information of copyright protection signal is recorded on the CD; and the record resume that will represent to write down the copyright protection object information are stored in the storer; under the situation that will be recorded in this copyright protection object information Delete All on the CD; when the taking-up that receives this CD requires, be judged as and take out (YES).
For example, when for having expression when having write down the CD of record resume of copyright protection object information and having carried out the operation of this copyright protection object information of Delete All, just delete this record resume.When the taking-up that receives this CD requires, confirm the record resume of relevant this CD in the storer.Then, if there is not expression the copyright protection object information to be recorded in record resume on this CD, then is judged as and takes out (YES).When being not this situation, then being judged as and taking out (NO).
If according to this example, information (copyright protection object information) can be recorded on the recordable CD, be used for the individual and appreciate.In addition, (for example, information such as family's picture recording image that user oneself takes) situation by deleting this copyright protection object information, just can be taken out CD for 1 video disc recording copyright protection object information and information in addition.For example, when interchanger 22 is taken,, just new CD can be changed by deleting unwanted copyright protection object information.
Above-mentioned example I-2～I-7 is different with example I-1, also has such effect, even CD is recordable dish, if also there is not record, just can go to replace with the different dish of capacity, and so on.
Information recording/reproducing apparatus of the present invention preferably possesses the interchanger that resembles optical disc apparatus shown in Figure 1 20.Owing to possess interchanger; even forbid the situation of information medium to the outer taking-up of device by handling the copyright protection object information; also can utilize bulky information, and be used for being the personal interest service neatly by methods such as exchange message medium in device.
In above-mentioned example I-1-I-7, be that example is illustrated with the CD, but other recording medium such as the hard disk that also goes for unloading down, floppy disk, tape.For example,, when not allowing to take out, not cannot take out, but, when allowing to take out, lock as long as remove this as long as this hard disk of locking can not get final product it from the disengaging of hard disk connecting portion if hard disk changes above-mentioned interchanger into a plurality of hard disk connecting portions.
(example II)
This example can record on the CD by key message (device information) specific or the information recording/reproducing apparatus that identification record is used when recording the copyright protection object information on the CD together.On the other hand, the information regenerator (comprising the regeneration isolated plant that can not write down) of the content information of regenerative recording on CD being given can be specific or discern the key message (device information) of this device.When the content information of information regenerator regenerative recording on CD, device information just is attached on the content information, and, just do not forbid the regeneration of this content information simultaneously when the device information of this device information and information regenerator.
Therefore; under the situation of 1 CD with copyright protection object information and information in addition (for example user oneself take family's video information) record together; this CD can be taken out from information regenerator, again with other information regenerator go to regenerate content information beyond the copyright protection object information.
Device information is intrinsic identification serial number, identification sign or the secret signal of information recording/reproducing apparatus or information regenerator.Such device information can or be recorded among the interior ROM (Readonly Memory is made of IC mostly) of device, perhaps is recorded in the holographic memory in the device, perhaps is recorded in the bar code in the device, and perhaps the difference by wiring reflects.
Have again, also can give diverse device information, perhaps, also can give identical device information the multiple arrangement of certain limit to each table apparatus.For the former, the copyright protection object information is not because if be that its device of record just can not be regenerated, so can protect literary property more effectively.For the latter, can limit user's scope, have only several users of the device of those device informations that to have given identical just can carry out the regeneration of copyright protection object information.
When information regenerator was the regeneration isolated plant, device information also can be only to represent the information that regeneration is special-purpose.That is, give different device informations respectively also can for the regeneration isolated plant, and give common device information.Because of writing down the copyright protection object information on the CD is to be only limited to recordable information recording/reproducing apparatus, so the regeneration isolated plant is inevitable different with the information recording/reproducing apparatus that has write down the copyright protection object information.Therefore, the regeneration that has added the content information of device information bans use of the regeneration isolated plant usually.So,, can ban use of the regeneration isolated plant to go to regenerate equally and add the content information of device information even the regeneration isolated plant is not given other device information and given common device information.And, by giving common device information to the regeneration isolated plant, because of (for example using simple method, the IC that has write down common apparatus information is assembled in regeneration method such as in the isolated plant) just can additional device information, so, can make the regeneration isolated plant that has added device information cheaply.
Below, use Fig. 5～Fig. 9 to be described more specifically device information.
(example II-1)
Operation when using Fig. 5 that the recorded content information of this example is described.
As shown in Figure 5, when recorded content information in CD, judge whether this content information must will protect the information (copyright protection object information) (step 41) of literary property.Be the judgement of copyright protection object information, for example can judge whether content information has added the copyright protection signal that example I-3 had illustrated.When being the copyright protection object information, then note (step 42) as ' key ' information with the content information device information that information record carrier is intrinsic.On the other hand, if the information beyond the copyright protection object information is not then carried out said apparatus recording of information (step 43).
Device information for example can be used for getting up to carry out record with this content information associated in the zone (for example management area) of the necessary information of the content information of regenerative recording on CD (for example management information) at record.
If according to this example, can use same device that information (copyright protection object information) is recorded on the recordable CD, be used for the individual and appreciate.In addition; for the copyright protection object information; apparatus, information recording when it is write down gets off; ban use of device to regenerate with device information different with this device information; so, as long as when sending the copyright protection object information, add the signal that expression is necessary to carry out copyright protection, after this; concerning the literary property owner, do not need to carry out any disposal and just can realize copyright protection.
(example II-2)
Operation when using Fig. 6 that the recorded content information of this example is described.
As shown in Figure 6, when to the video disc recording content information, judge that this content information is a copyright protection object information (step 51).If the information beyond the copyright protection object information is not then carried out the record of device information, a recorded content information (step 52).More than identical with example II-1.
On the other hand, if whether the copyright protection object information is considered that quality with content information is reduced to write down (step 53) more than the required standard.When the reduction quality writes down, do not carry out the record of device information, a recorded content information (step 52).When not reducing quality and write down, then with content information, the device information that information record carrier is intrinsic is noted (step 54) as ' key ' information.
The reduction of above-mentioned information quality is meant the such operation that had illustrated in above-mentioned example I-4.Have again, because of the different differences that produce the reduction degree of method that reduce information quality.In the judgement of step 53, when the degree that reduces when quality is not enough, be judged as then in fact that quality does not reduce, can pen recorder information.
For example, I-4 is the same with example, and the sender of copyright protection object information can drop to information quality actually the content what degree just calculates outside the copyright protection object and note with the copyright protection signal.For such situation,, just do not carry out the record of device information as long as information quality is reduced to more than the degree of defined.Therefore, can realize the desirable copyright administration of literary property owner.
If according to this example, to the copyright protection object information, as condition, just can allow freely regenerating or duplicating of recorded information with suitable reduction quality of information, can take into account the convenience of the protection and the information utilization of literary property.
Have again, this example in step 53, even be judged as the situation that quality of information is reduced, though when the copyright protection regulation of this content information be that quality reduces when also forbidding duplicating, also device information can be noted (step 54) together.
(example II-3)
Use Fig. 7 that this example is described.
Even this example is under situation about copyright protection object information and device information being write down together according to above-mentioned example II-1, II-2; when having carried out making the quality that is recorded in this copyright protection object information on the CD to be reduced to operation more than the required standard thereafter, just delete device information.
That is, when the content information that is recorded in rewritable CD being made the operation of its quality reduction (step 61), judge whether the content information of this operand has added device information (step 62).If added device information, then delete this device information (step 63).If there is not additional device information, then do not carry out the operation (step 64) of relative assembly information.Have again, in step 61, when not making the operation of quality of information reduction, also do not carry out the operation (step 64) of relative assembly information certainly.
The above-mentioned operation that information quality is reduced is meant carries out such operation of having illustrated to being recorded in content information on the CD in above-mentioned example I-4, this quality of information is reduced.After having carried out such operation, just there is not information (the operation information before that information quality is reduced) originally in CD.
This example produces the differences of reduction degree too because of the method difference that reduces information quality.Make quality be reduced to just delete device information of what degree on earth? this point can be set arbitrarily.When the degree that reduces when quality is not enough, be judged as then in fact that quality does not reduce, still can be with it as the copyright protection object.For example, I-4 is the same with example, and the sender of copyright protection object information can drop to information quality actually the content what degree just calculates outside the copyright protection object and note with the copyright protection signal.For such situation, as long as information quality is reduced to more than the degree of defined, with regard to delete device information.Therefore, can realize the desirable copyright administration of literary property owner.
If according to this example; even have be recorded in CD on the information regenerator of the different device information of device information; with suitable reduction quality of information as condition; just can allow freely regenerating or duplicating of content information, can take into account the protection of literary property and the convenience that information is utilized.
Have again; this example is in step 61; even be judged as the situation of having carried out making the operation that quality of information reduces, though when the copyright protection regulation of this content information be that quality reduces when also forbidding regenerating, also can not carry out the operation (step 64) of relative assembly information.
(example II-4)
Order when using Fig. 8 that the content information that writes down in the regeneration CD is described.
As shown in Figure 8, when reproducing contents information, at first, whether the content information that judgement will be regenerated has added device information (step 71).When not having additional device information, just allow reproducing contents information (step 72).When having added device information, then judge it whether with the device information of the information recording/reproducing apparatus that will regenerate or information regenerator consistent (step 73), if consistent, then allow regeneration (step 72), if inconsistent then refusal regeneration (step 74).Have again, when refusal regeneration, wish to show because of the unrenewable content of copyright protection.
If according to this example, if when record to copyright protection object information applicator information, just can and duplicate the certain restriction of setting to the regeneration of copyright protection object information.Therefore, after sending the copyright protection object information, concerning the literary property owner, do not need to carry out any disposal and just can realize copyright protection.

In addition; as another copyright protection method; when recording the copyright protection object information on the CD, can be specific or the key message (regional information) that the area is set or the place is set of the employed information recording/reproducing apparatus of identification record note down on the CD together.On the other hand, the information regenerator (comprising the regeneration isolated plant that can not write down) of the content information of reproduced light disc recording being given can be specific or the key message (regional information) in identification regeneration area or place.When the content information of information regenerator reproduced light disc recording, if content information has added regional information, and the regional information of this area's information and information regenerator is not simultaneously, and then the regeneration of this content information is under an embargo.
Therefore; under the situation with copyright protection object information and information in addition (for example user oneself take family's video information) record together on 1 CD; this CD can be taken out from information regenerator, again with the information regenerator that is located at other place go to regenerate content information beyond the copyright protection object information.
Applicator in advance below the regional information of pen recorder and the regional information of regenerating unit for example can resemble.For example, receiving trap (having gps signal receiving antenna and gps signal pick-up unit at least) Vehicular navigation system etc. is widely used, that receive the GPS information of sending here from moonlet is located in the information recording/reproducing apparatus (comprising the information regenerator that regeneration is special-purpose), and the information relevant with the place of the present setting of this information recording/reproducing apparatus that obtains from GPS information is given to information recording/reproducing apparatus.Go down like this, can constitute such system easily, promptly having only regeneration place and record place is same place (for example, same state, areal, same place, the same family etc.), just allows reproducing contents information.In addition, also can not use artificial Satellite GPS information, and use telephone line to give information recording/reproducing apparatus the location information that is provided with of information recording/reproducing apparatus.In addition, also can be with the user that location information inputs to device that is provided with of device.Perhaps, also can in advance the place to use information of device be imported into by fabricator who installs or sales force etc.
The same the carrying out of situation of the device information that the order of regional information, the content information of regenerative recording on CD that has write down to video disc recording regional information, deletion can illustrate with example II-1～II-4.
That is, when recording the copyright protection object information on the CD, the regional information in specific record place is recorded on the CD together.Thus, in areal, information (copyright protection object information) can be recorded on the CD-R, be used for the individual and appreciate.In addition; for the copyright protection object information; during because of record regional information is noted; ban use of device to regenerate (promptly with regional information different with this area's information; forbidding regeneration with record area from different places), so, after sending the copyright protection object information; concerning the literary property owner, do not need to carry out any disposal and just can realize copyright protection.
In addition, even the copyright protection object information is recorded in situation on the CD, when reducing this quality of information and write down, can not write down regional information.Therefore,, as condition, just can allow freely to regenerate or duplicate the information that has write down, can take into account the protection of literary property and the convenience that information is utilized with suitable reduction quality of information to the copyright protection object information.
In addition, under the situation of the operation that the quality of the CD that writes down the copyright protection object information of having given regional information having been carried out make the copyright protection object information reduces, also can delete this area's information.Therefore, though to the record area from different places of copyright protection object information,, can allow freely to regenerate or reproducting content information as condition with suitable reduction quality of information, can take into account the protection of literary property and the convenience that information is utilized.
In addition, the content information in the CD of having given regional information is regenerated, have only when the regional information of this content information is consistent with the regional information in regeneration place just to be allowed to, then refuse regeneration when inconsistent.Therefore, as long as the regional information during to copyright protection object information addition record, just can and duplicate certain restriction is set the regeneration of copyright protection object information.So, after sending the copyright protection object information, concerning the literary property owner, do not need to carry out any disposal and just can realize copyright protection.
In above-mentioned example II, III, be that example is illustrated with the CD, but other recording medium such as the hard disk that also goes for unloading down, floppy disk, tape.
If according to the present invention, just can realize to take into account the information recording/reproducing apparatus of copyright protection and individual use information by simple formation.
