According to embodiments of the invention, magnetooptical disc is used as recording medium.According to present embodiment, be with substantially the same according to the dish of so-called MD (mini-disk) system such as the physical property of the form factor of dish.Yet, according to the data on the dish of present embodiment and the arrangement of data on the dish be with traditional MD on different.

In fact, use FAT (file allocation table) system as file management system, be used for writing down and reappear such as the such content-data of voice data according to the equipment of embodiments of the invention.Therefore, equipment can guarantee the compatibility of the file system used with traditional personal computer.

In this example, the term in this instructions " FAT " or " FAT system " are often used as and are the various file system based on PC of representative.Therefore, the predetermined file system of using based on FAT, VFAT (virtual FAT), the FAT 32 that uses and the NTFS (NT file system (being also referred to as New Technology File System)) that uses do not planned to represent in these terms in Windows98/ME/2000 in Windows (registered trademark) 95/98 in DOS (disk operating system).NTFS is the file system of using in WindowsNT operating system or (randomly) Windows2000.NTFS from/to dish read/when writing data, write down and read file.

In addition, according to embodiments of the invention, the error correction system and the modulating system of current MD system are corrected, so that the recording capacity of data and reliability are modified.And according to embodiments of the invention, content-data is encrypted and prevent bootlegging, so that the copyright of protection content-data.

As for the recording form, the technical manual of MD of future generation 1 system and the technical manual of MD of future generation 2 systems are arranged.The technical manual of next generation MD 1 system is used the identical dish (that is physical medium) of dish with current MD system.The technical manual of of future generation MD 2 systems uses its form factor and profile to be that dish with current MD system is identical but dish that its recording density on the straight line record direction is increased by use magnetic super-resolution (MSR).These systems are developed by the inventor of present patent application.

Current MD system uses and is comprised in the magneto-optic disk of the 64mm diameter in the box as recording medium.The thickness of dish is 1.2mm.Center at dish is formed with the center pit with 11mm diameter.Box is that 68mm is long, the wide and 5mm height of 72mm.

According to the shape of the dish of the technical manual of MD of future generation 1 system and its box is identical with dish and box according to the technical manual of MD of future generation 2 systems.In the dish according to the technical manual of MD 1 system of future generation and MD of future generation 2 systems, as the dish of current MD system, ingress area begins at the center 29mm from them.

Next generation MD 2 systems will stipulate that track space is that 1.2 μ m are to 1.3 μ m (for example, 1.25 μ m).On the contrary, use the MD of future generation 1 system regulation of the dish of current MD system, track space is 1.6 μ m.Next generation MD 1 system regulation, bit length is 0.44 μ m/ bit.Next generation MD2 system regulation, bit length is 0.16 μ m/ bit.MD 1 system regulation of future generation and MD of future generation 2 systems will stipulate that redundance is 20.50%.

Recording capacity in the line density direction of the dish of MD of future generation 2 systems is increased by using magnetic super-resolution technology.Magnetic super-resolution technology is used when incised layer is heated to predetermined temperature, is moved because incised layer becomes the neutral state of magnetic and transfers to the magnetic wall that reappears layer, and little mark is rendered as a kind of like this phenomenon of big beam spot.

In other words, has magnetosphere at least, as the recording layer of recorded information wherein according to the dish of the technical manual of MD of future generation 2 systems; Incised layer; With another magnetosphere, from this layer redisplaying information.These layers are formed on transparent substrate.Incised layer is to regulate the layer of exchange cohesive force for it.When incised layer was heated to predetermined temperature, incised layer became magnetic neutral state.The magnetic wall of transferring to recording layer 101 is transferred to the magnetosphere from its redisplaying information.As a result, little mark is rendered as beam spot.When data were recorded, using wherein, laser pulse can generate tiny mark with the technology of magnetic field modulation.

Have deeper and the groove that more precipitously forms according to the dish of the technical manual of MD of future generation 2 systems compared with traditional MD dish, so as to improve go-the track surplus and suppress from the crosstalking of ground, wig-wag signal crosstalk and focus is leaked.The groove that forms on the dish according to the technical manual of MD of future generation 2 systems has scope and is for example degree of depth from 160nm to 180nm.The groove of this dish has scope for for example spending to the degree of tilt of 70 degree from 60.The groove of this dish has scope and is for example width from 600nm to 700nm.

As the optical technology normality condition, MD of future generation 1 system regulation, the wavelength X of laser instrument is 780nm, and the numerical aperture NA of the objective lens of optical head is 0.45.Similarly, as the optical technology normality condition, MD of future generation 2 systems will stipulate that the wavelength X of laser instrument is 780nm, and the numerical aperture NA of the head of light is 0.45.

As the optical technology normality condition, MD 1 system of future generation and MD of future generation 2 systems regulation, the groove register system is used as register system.In other words, these systems use the groove that is formed on panel surface as writing down it on and from the track of its playing data for broadcasting.

Current MD system regulation is used as the error correcting code coded system based on the convolutional code of ACIRC (advanced cross interleave Reed-Solomon sign indicating number).On the contrary, MD 1 system of future generation and MD of future generation 2 systems regulation are used as the error correcting code coded system by RS-LDC (the long distance codes of Reed-Solomon-) and the combined piece finishing type code that forms of BIS (burst indicator subcode).By piece finishing type error correcting code, do not need to use the chainning sector.In the error correction system combined by LDC and BIS, if burst error takes place, then errors present can be detected by BIS.Can use then corresponding to the LDC sign indicating number of errors present and carry out erasure correction.

As addressing system, use the wobble groove system.In the wobble groove system, form the helix groove, and form swing as address information in the both sides of groove.This addressing system is called as ADIP (address on pre-groove).Current MD system, MD of future generation 1 system are being different with MD of future generation 2 systems aspect their line density.Though current MD system uses the convolutional code that is called as ACRC as error correcting code, MD 1 system of future generation and MD of future generation 2 systems use by LDC and the combined piece finishing type code that forms of BIS.Therefore, current MD system they redundance and the relative position of ADIP and data aspect different with MD of future generation 1 system with MD of future generation 2 systems.Therefore, the technical manual of MD of future generation 1 system is handled the different ADIP signal of technical manual with current MD system.Next generation MD 2 systems are according to its technical manual regulation ADIP signal.

Though current MD system uses FEM (8 to 14 modulation) system as modulating system, but the technical manual of MD 1 system of future generation and MD of future generation 2 systems regulation RLL (1,7) PP (RLL: limited working length, PP: parity checking keeps/forbids rmtr (repeating minimum jump operation length)), be called as the 1-7pp modulating system.Next generation MD 1 system regulation has the Viterbi decoding system of the partial response PR (1,2,1) that is used for data detection system, and MD of future generation 2 systems regulation has the Viterbi decoding system of partial response PR (1 ,-1) ML that is used for data detection system.

The technical manual of current MD system, MD of future generation 1 system and MD of future generation 2 systems is given for the CLV (constant linear velocity) or the ZCAV (region constant angular speed) of disc driving system.The technical manual required standard linear velocity of next generation MD 1 system is 2.4m/sec.The technical manual required standard linear velocity of next generation MD 2 systems is 1.98m/sec.On the other hand, the technical manual of current MD system regulation is respectively 1 for the standard lines speed of 60 fens clock dials and 74 fens clock dials, 2m/sec and 1.4m/sec.

Use the technical manual of MD of future generation 1 system of the dish of current MD system to stipulate that total data recording capacity of per 80 minutes clock dials is about 300 megabyte.Since the technical manual regulation 1-7pp modulating system of MD of future generation 2 systems rather than be used for the EFM system of modulating system, the window surplus of the dish of new generation MD 1 system be current MD system dish 0.666 rather than 0.5.As a result, the dish of new generation MD 1 system is finished the high 1.33 times high density of dish compared with current MD system.In addition, because MD of future generation 1 system is given for the combination of the BIS and the LDC of error correction system, rather than the ACIRC system, because the data efficiency of MD of future generation 1 system improves, system can finish the high 1.48 times recording density compared with current MD system.Altogether, MD of future generation 1 system can finish 2 times data capacity of current MD system.

Dish according to MD of future generation 2 systems that use magnetic super-resolution technology has the density that is higher than current MD system and MD of future generation 2 systems.Total recording capacity according to the dish of the technical manual of MD of future generation 2 systems is about the 1G byte.

Of future generation MD 1 system regulation is 4.4Mbits/sec as the data rate of standard lines speed.Next generation MD 2 systems regulation, data rate is 9.8Mbits/sec.

As shown in Figure 3A, on the ingress area that the control information of the ADIP signal inside circumference that is recorded in dish makes progress in the footpath from the center of dish.On the dish of MD 2 of future generation, do not form the PTOC of the spacing of projection at ingress area.But, use the control information of ADIP signal.Recordable zone is from the outer circumferential of ingress area.Recordable zone is that wherein groove is formed the recordable/reproducible zone of the guiding groove of track record.In recordable zone, record is according to the modulated data of 1-7pp modulating system.

Shown in Fig. 3 B, comprise by magnetic thin film according to the dish of the technical manual of MD 2 of future generation consisting of the magnetosphere 101 that is used for the recording of information layer, incised layer 102 and from another magnetosphere 103 of its redisplaying information.Incised layer 102 is to regulate the layer of exchange cohesive force for it.When incised layer was heated to predetermined temperature, incised layer 102 became magnetic neutral state.The magnetic wall of transferring to recording layer 101 is transferred to the magnetosphere 103 from its redisplaying information.Therefore, be rendered as mark in the micro mark on the recording layer 101 in the amplification of the beam spot from the magnetosphere 103 of its playing data for broadcasting.

On the dish of MD 2 of future generation, above-mentioned UID is recorded in the zone on the inner periphery in recordable zone.The zone that is used for UID is the reproducible and zone that can not write down that is used for consumer's record and reproducing apparatus.On the dish of MD 2 of future generation, when dish was produced, UID was according to being recorded with the BCA that is used for DVD (digital universal disc) or the like (burst cutting area territory) technology that technology is identical.When dish had produced, because UID has generated and has been recorded thereon, UID can be managed.Therefore, the security of the dish of MD 2 of future generation is that the dish of the MD of future generation 1 that is generated according to random number when dish is initialised is more improved compared with its UID.The details of form of UID or the like is described in the back.

Complicated in order to prevent to illustrate, the prerecorded area of the UID of the dish that is used for MD 2 of future generation is called BCA.

The information of ingress area can be distinguished the dish of MD 1 of future generation and the dish of MD of future generation 2.In other words, when detecting the PTOC of protruding spacing in ingress area, the result of detection represents the dish of current MD system or the dish of MD of future generation 1.When detecting the PTOC of spacing of ADIP signal rather than projection from ingress area, the result of detection represents the dish of MD 2 of future generation.Alternatively, depend on the UID that is recorded among the BCA, the dish of MD 2 of future generation can separate with the panel of MD 1 of future generation.The dish of MD 1 of future generation and the dish of MD of future generation 2 can be distinguished by being different from above-mentioned method.

Fig. 4 shows the structure according to the recordable zone of the dish of the technical manual of MD 2 of future generation.As shown in Figure 4, be recorded in recordable zone according to the modulated data of 1-7pp modulating system.In the inner periphery that is used for according to the zone of the modulated data of 1-7pp modulating system, the track that forms the DDT zone and keep.The DDT zone is formed for using the data that the zone of physics defect area is replaced in management.

In fact, the admin table that management comprises the replacement zone in the recordable zone that is used to replace the physics defect area used in record in the DDT zone.Record is confirmed as the logical group of the cluster of defective in admin table.And record is designated as one or more logical group of the logical group of replacement in admin table.The above-mentioned UID of record in the DDT zone.Storage is used to protect the information of content in the track that keeps.

In addition, be used for having the FAT zone according to the zone of the modulated data of 1-7pp modulating system.The FAT zone is the zone managed according to the FAT system of data wherein.The FAT system is according to the FAT systems management data that uses in general purpose personal computer.

The dish of MD 2 of future generation does not have the U-TOC zone.When the dish of MD 2 of future generation is loaded onto the player of MD 2 of future generation, be formed on the DDT of preposition, the track and the FAT zone of reservation is read out, and data are managed according to the FAT system.

The dish of MD 1 of future generation and the dish of MD of future generation 2 do not need the initialization operation of expensive time.In other words, do not need initialization operation according to the dish of the technical manual of MD 1 of future generation with according to the dish of the technical manual of MD 2 of future generation, but create the table of minimal amount, such as the track and the FAT table of DDT, reservation.Therefore, when the dish according to the technical manual of MD 1 of future generation or MD of future generation 2 systems was untapped dish, data can directly be recorded in the recordable zone of dish and be reproduced from this zone.

As mentioned above, when the dish of MD 2 of future generation was produced, UID was created and is recorded thereon.Therefore, the dish of MD 2 of future generation can be managed more safely compared with the dish of current MD system.Yet the number of plies of the dish of MD 2 of future generation is greater than the number of plies of the dish of current MD system.The cost of the dish of MD2 of future generation is than the cost costliness of the dish of current MD system.Therefore, proposed to be called as the dish of MD 1.5 of future generation.The dish of MD 1.5 of future generation has recordable zone, ingress area and the export area identical with the dish of MD 1 of future generation.In addition, the dish of MD 1.5 of future generation has UID, and it is used in the BCA of the dish of MD 2 as DVD, of future generation.

After this, unless need, just omit the explanation of MD of future generation 1.5 systems.In other words, with respect to UID, MD 1.5 of future generation is based on MD's 2 of future generation.On the other hand, with respect to the record and the reproduction of voice data, MD 1.5 of future generation is based on MD1's of future generation.

Then will describe UID in detail.As mentioned above, when the production dish, be used for technology DVD, that be called as BCA, UID be recorded on the dish of MD 2 of future generation by use.Fig. 5 shows the example of form of the general introduction of UID.Whole UID is called as UID record block.

In the UID piece, two bytes are the districts that are used for the UID sign indicating number.Two bytes of UID sign indicating number--promptly, 16 bits--four bits of high-order be used for determining dish.When four bits were [0000], it represented the dish of MD 2 of future generation.When four bits were [0001], it represented the dish of MD 1.5 of future generation.Other values are preserved for expansion in the future.12 bits of the low order of UID sign indicating number are the application ID that can distinguish 4096 types business.

The version number of 1 byte is followed in UID sign indicating number back.The version number district follows the back data length district of 1 byte.The representative of data length district is at the data length of the UID recorded data zone of back, data length district.The UID recorded data zone is designated as the 4m that is no more than 188 bytes (m=0 wherein, 1,2...) byte.The UID recorded data zone can be stored the unique ID that is created by predetermined method.Unique ID can recognition data itself.

On the dish of MD 1 of future generation, in the UID recorded data zone, can write down the ID that creates according to random number.

Can create its data length and be no more than UID record blocks 188 bytes, a plurality of.

3. signal format

Then, will the signal format of MD 1 system of future generation and MD of future generation 2 systems be described.Current MD system uses the ACIRC of convolutional code as error correction system.In current MD system, be used as the recording access unit by the sector of forming corresponding to 2352 bytes of the data volume of subcode piece.When using convolutional code, the error correcting code sequence extension is to a plurality of sectors.Therefore, when data are rewritten, must between adjacent sector, form the sector of link.As addressing system, ADIP is used as the channel system of swing, wherein forms single helix groove, and the both sides that are formed on groove as the swing of address information.In current MD system, the ADIP signal be arranged to make the sector formed by 2352 bytes each can be inserted best.

On the other hand, the technical manual of MD of future generation 1 system and the technical manual regulation of MD of future generation 2 systems are used the piece finishing type sign indicating number that is combined by LDC and BIS, and the recording access unit is the 64k byte.Piece finishing type sign indicating number does not need the chainning sector.Therefore, use the technical manual regulation of the MD of future generation 1 of current MD system, the ADIP signal changes according to new register system.The technical manual regulation of MD 2 of future generation, the ADIP signal changes according to it.

With reference to Fig. 6, Fig. 7 and Fig. 8, be described in the error correction system of using in MD 1 system of future generation and MD of future generation 2 systems.In MD 1 system of future generation and MD of future generation 2 systems, use the error correcting code coded system of LDC shown in Figure 6 and Fig. 7 and BIS shown in Figure 8 combined.

Fig. 6 shows the structure according to the piece of the error correcting code coding of LDC.As shown in Figure 6, piece is made of two-dimensionally 304 bytes (horizontal direction) * 216 bytes (vertical direction).Piece has 32 sectors, and each sector is made up of the 2k byte.The error correcting code EDC of nybble is added to each sector.The Reed-Solomon sign indicating number of a plurality of 32 bytes is added to the vertical direction of piece.

Fig. 7 and Fig. 8 show the structure of BIS.As shown in Figure 7, the data of per 32 bytes are placed the BIS of 1 byte, the data of (38 * 4=152 byte), the BIS data of three bytes and the frame synchronization of 2.5 bytes, and promptly 157.5 bytes are altogether formed a frame.

As shown in Figure 8, a BIS piece is made up of 496 frames, and each frame has above-mentioned structure, BIS data (3 * 496=1488 byte) comprise user's control data of 576 bytes, the address location number of 144 bytes and the error correcting code of 768 bytes.

Because the BIS data are made up of the data of 1488 bytes and the error correcting code of 768 bytes, mistake can be repaired very doughtily.When per 38 bytes embed a BIS sign indicating number,, then can detect its errors present if happen suddenly.According to errors present, can carry out erasure correction with the LDC sign indicating number.

As shown in Figure 9, the ADIP signal is registered as the swing that is formed on single helix groove both sides.In other words, the ADIP signal has the address date of being modulated by FM.The ADIP signal is registered as the swing of the open channels of disk material.

Figure 10 shows the sector format of the ADIP signal of MD 1 of future generation.

As shown in figure 10, corresponding to the ADIP sector of a sector of ADIP signal by four bits synchronously, low step bit part, the ADIP sector number of 8 bits and the error-detecging code CRC of 14 bits of the ADIP cluster of the higher order bits part of the ADIP cluster of 8 bits number, 8 bits number form.

Be signal synchronously, detect the beginning of ADIP sector by it with predetermined pattern.Because current MD system uses convolutional code, system needs the chainning sector.The chainning sector number has negative value " FCh ", " FDh ", " FEh " and " FFh " (wherein h represents sexadecimal number).On the other hand, because MD of future generation 1 uses the dish of current MD system, the form of the ADIP sector of MD 1 of future generation is identical with current MD system.

As shown in figure 11, MD of future generation 1 system regulation, an ADIP cluster is made up of 36 sectors of ADIP sector number " FCh " to " FFh " and " 0Fh " to " 1Fh ".As shown in figure 10, the data of two record blocks (each 64k byte) are arranged in the ADIP cluster.

Figure 12 shows the structure of the ADIP sector of MD 2 of future generation.The technical manual regulation of MD 2 of future generation, the ADIP sector is made up of 16 sectors.Therefore, the ADIP sector number can be represented with 4 bits.Because MD of future generation system uses piece finishing type error correcting code, system does not need the chainning sector.

When track n is that second half part and the track n+1 of the indexed division of one of them audio data file is when being in the starting point of another audio data file, as shown in figure 44, title is added to the data of the track n that is divided by index.As a result, the audio data file of song M32 is created.The title of the audio data file of track n+1 is removed, and the voice data of the track n+1 of song M41 is connected to the audio data file of track n+1.Therefore, the song M32 of two tracks and M41 are connected to the song M51 of a track.

In order to finish above-mentioned process, provide to be used for title is added to the function and the title and another function that is connected audio data file and another audio data file that are used to remove audio data file that is transformed into an audio data file by the track of index division, with another an encryption keys track and a voice data by the index division.

8. the operation of disc system when being connected to personal computer

In order to allow MD 1 of future generation and MD of future generation 2 to have compatibility with personal computer, these systems use FAT systems as data management system.Therefore, the dish of the dish of MD 1 of future generation and MD of future generation 2 not only can processing audio data, and can handle the computer data of being read and writing by personal computer.

Disk drive device 1 is read and is reappeared voice data from coiling 90.Therefore, consider the accessibility of portable disc drive unit 1, preferably the adjoining land recording audio data.On the other hand, when personal computer write data into dish, personal computer distributed blank zone to give dish, and need not consider continuity.

Therefore, in record and reproducing apparatus according to embodiments of the invention, personal computer 100 and disk drive device 1 are connected to USB station 7.When data when personal computer 100 is written to the dish 90 that is loaded in disk drive device 1, the general calculation machine data is written to dish 90 under the control of disk drive device 1 side in file system; Voice data is written to dish 90 under the control of disk drive device 1 side in file system.

Figure 45 A and 45B be describe managing power at personal computer 100 and disk drive device 1 by USB station 7 (7) the connected states synoptic diagram that is transmitted of the type of the basis data that will be written into down.Figure 45 A shows the example when personal computer 100 is sent to disk drive device 1 and be recorded in the dish 90 that is loaded onto disk drive device 1 of general-purpose computations machine data wherein.In this case, the FAT of dish 90 is managed by file system on the screen of personal computer 100 sides.

In this case, suppose that dish 90 is according to the formatted dish of MD 1 of future generation or MD of future generation 2.

In other words, personal computer 100 1 sides are handled the disk drive device 1 that is connected to it, as the dismountable dish by personal computer 100 management.Therefore, data be read and be write to personal computer can from the dish 90 that is loaded onto disk drive device 1, and like this, data are read and write to personal computer 100 from coiling flexibly.

The file system of personal computer 100 1 sides can be provided as the function of OS (operating system) with the basic software that is installed in personal computer 100.Just as the well-known, OS is recorded in for example hard disk drive of personal computer 100 as the preset program file.When personal computer 100 was activated, program file was read out and is performed, so that each function of OS is provided.

Figure 45 B shows the example when personal computer 100 is sent to disk drive device 1 and be recorded in the dish 90 that is loaded onto disk drive device 1 of hard disc data wherein.For example, voice data is recorded in recording medium, for example the hard disk drive of personal computer 100 (HDD).

Suppose to make personal computer 100 voice data to be write the dish 90 that is loaded onto disk drive device 1 according to the common software of ATRAC compressibility coding audio data, and the 90 deletion voice datas of the dish from be installed in personal computer 100.Common software also has with reference to the track index file of the dish 90 that is loaded onto disk drive device 1 and browses the function that is recorded in the orbit information on the dish 90.Common software is recorded in for example HDD of personal computer 100 as program file.

For example, the voice data that description is recorded in the recording medium of personal computer 100 is recorded to the situation of the dish 90 that is loaded onto disk drive device 1.In this case, suppose that above-mentioned common software is activated,

At first, the user operates personal computer 100, so that the predetermined voice data (calling voice data A) that is recorded among the HDD is recorded the dish 90 that is loaded onto disk drive device 1.According to user's operation,, make voice data A be recorded to dish 90 by common software output write request order.Write request 1 order sends to disk drive device 1. from personal computer 100

After this, the HDD from personal computer 100 reads voice data A.The common software that is installed in personal computer 100 carries out encoding process according to the ATRAC compressibility for voice data A, and voice data A is transformed into the ATRAC packed data.The voice data A that has been transformed into the ATRAC packed data is sent to disk drive device 1 from personal computer 100.

Disk drive device 1 one side joints are received the write request order from personal computer.As a result, disk drive device 1 recognizes that the voice data that is transformed into the ATRAC packed data is transmitted from personal computer 100, and the data that transmit are recorded on the dish 90 as voice data.

The voice data A that disk drive device 1 receives from personal computer 100 by USB station 7.Disk drive device 1 sends to media-driven part 2 to voice data A by USB interface 6 and storer transfer control 3.When system controller 9 sent to media-driven part 2 to voice data A, system controller 9 control media-driven parts 2 were so that voice data A is written to dish 90 according to the FAT management method of disk drive device 1.In other words, voice data A is written to dish 90 according to the FAT system of disk drive device 1 by adjoining land, like this, four record blocks of voice data A, promptly 64 bytes * 4 once are written to dish 90 as smallest record length.

Before data were written to dish 90 fully, data, state and order exchanged between personal computer 100 and disk drive device 1 according to predetermined agreement.Therefore, overcurrent and undercurrent so that do not take place in the data transfer rate Be Controlled in the cluster cache device 4 of disk drive device 1 one sides.

In the operable order of personal computer 100 1 sides,, for example be the removal request order except being the above-mentioned write request order.The removal request order is to make disk drive device 1 deletion be recorded in the voice data on the dish 90 that is loaded onto disk drive device 1.

When personal computer 100 and disk drive device 1 are connected and coil 90 when being loaded onto disk drive device 1, above-mentioned common software makes disk drive device 1 read the track index file from coiling 90.Data are read out and are sent to personal computer 100 from disk drive device 1 from the track index file.Personal computer can show the exercise question list that is recorded in the voice data on the dish 90.

When personal computer 100 was attempted to delete specific voice data (voice data B) from the exercise question list that shows, the information of the voice data B that indicates deleted was sent to disk drive device 1 together with the removal request order.When disk drive device 1 receives the removal request order, the voice data B of disk drive device 1 removal request under the control of disk drive device itself.

Because voice data is deleted under the control of disk drive device startup FAT system, can carry out the huge file that is used for from being made up of a plurality of songs of voice data and delete processing of audio data.

9. be recorded in the copy limit of the voice data on the dish

In order to protect the copyright that is recorded in the voice data on the dish 90, should limit the voice data that is used for being recorded in dish 90 to be written to duplicating of another recording medium or the like.Consider to be recorded in the HDD that the voice data of dish 90 is sent to personal computer 100 and is recorded in personal computer 100 from disk drive device 1.

In this example, suppose that dish 90 is according to the formatted dish of MD 1 of future generation or MD of future generation 2.In addition, be performed under the control of supposing to will be described later, check conveying operations, verification input (check-in) operation or the like the above-mentioned common software in being installed in personal computer 100.

In steps A shown in Figure 46, the voice data 200 that is recorded in dish 90 is moved to personal computer (PC) 100.Term " moves " and is meant that wherein target audio data 200 are copied to personal computer 100 and deletion target audio data from source record medium (dish 90).In other words, when data were moved, data were deleted from the source, and data are moved to the destination.

Wherein the operation that subtracted increment 1 of the data number of copy times that is copied to another recording medium and permission from a recording medium is called check-out (verification output).On the contrary, wherein the operation that added increment 1 of the number of copy times of the permission in data and " verification output " source deleted from the destination of " verification output " is called check-in (" verification input ").

When voice data 200 was moved to personal computer 100, voice data 200 was moved to the recording medium of (as voice data 200 ') personal computer, and for example HDD, and voice data 200 is deleted from source tray 90.At step B shown in Figure 46, personal computer is arranged on the number of times of " the verification output " of permission in the mobile voice data 200 '.In this example, " verification output " number of times (CO) of permission is set to 3 times, with " @ " expression.In other words, voice data 200 ' can be outputed to the number of times 201 of the verification output that the external record medium permit from the personal computer verification.

The voice data 200 of " if verification output " deletion from source tray 90, it is inconvenient that the user can feel this.Therefore, quilt " verification output " is deposited into dish 90 again to the voice data 200 ' of personal computer 100.

When voice data 200 when personal computer 100 is written to source tray 90 again, at step C shown in Figure 46, " verification output " number of times of permission is consumed 1 time.Therefore, it is inferior that " verification output " number of times of the permission that finally obtains becomes (3-1=2).At step C shown in Figure 46, " verification output " number of times of the permission that is consumed is represented with " # ".Owing to be stored in the permission of the voice data 200 of personal computer 100 " verification output " remainder of number of times is 2 times, voice data 200 is not deleted from personal computer 100.In other words, the voice data 200 ' that is stored in personal computer 100 is copied to dish 90 from personal computer.On dish 90, voice data 200 " be recorded as the copy of voice data 200 '.

Permission " verification output " number of times 201 managed by the copyright management information (seeing Figure 27 B) of the track descriptor of orbit information table.Because the track descriptor is described for each track, permission " verification output " number of times 201 can such as music data, be set up for each track.Be used as the control information that voice data moves on to personal computer 100 from coiling the 90 track descriptors that are copied to personal computer 100.

When voice data from coiling 90 when being moved to personal computer 100, be copied to personal computer 100 corresponding to the track descriptor of the voice data that moves.Personal computer 100 is managed from coiling 90 voice datas that move according to the track descriptor.When voice data is moved to and records the HDD etc. of personal computer, the permission of the copyright management information in the track descriptor " verification output " number of times 201 is set to predetermined times (3 times in this example).

As copyright management information, except permission " verification output " the number of times 201, also manage identification sources " verification output " machine ID of machine and sign by " verification output " and the content ID of content (voice data).At step C shown in Figure 46, the machine ID of duplicating the destination machine according to corresponding to the machine ID in the copyright management information of the voice data that will be replicated by authentication.When the machine ID of copyright management information and the machine ID of duplicating the destination machine are inconsistent, can forbid that voice data is replicated.

Arrive C's in steps A shown in Figure 46 " verification output " in the sequence handled, the voice data on dish 90 is moved to personal computer 100, is rewritten to dish 90 from personal computer 100 then.Therefore, the user should carry out complicated and loaded down with trivial details step.In addition, because the user need read the readout time of voice data and voice data is rewritten to dish write time of 90 from coiling 90, he or she understands the sensation time loss.In addition, the user dislikes from coiling 90 deletion voice datas.

Therefore, when the voice data quilt that is recorded in dish 90 " verification output " time, above-mentioned intermediate steps is omitted, and is performed as it, like this, only finishes the result of step C shown in Figure 46.The example of this step then, is described.This step is the individual command by the user, such as " " verification output " is recorded in the voice data of the audio file A on the dish 90 ", is performed.

(1) copies to the HDD of personal computer 100 being recorded in the voice data of dish on 90.In addition, the part management data that is used for voice data is invalid, so that voice data on the deletion dish 90.For example, link corresponding to the link information TINFn of the track descriptor of voice data deleted from playing on the race-card.In addition, link corresponding to the link information TINFn of the track descriptor of voice data deleted from the programming file race-card.Alternatively, can be deleted corresponding to the track of voice data itself.Therefore, voice data can not be used on dish 90.As a result, voice data is moved on to personal computer 100 from coiling 90.

(2) when when voice data is copied to personal computer 100, also being copied to the HDD of personal computer 100 corresponding to the track descriptor of voice data in step (1).

(3) then, personal computer 100 is predetermined times, for example 3 times, is set to corresponding to the permission of copyright management information from the track descriptor that coils the 90 moving voice datas that are replicated and move " verification output " number of times.

(4) then, personal computer 100 is according to from coiling the content ID that the 90 track descriptors that duplicate obtain the voice data that is used to move.Content ID as representative can by " verification input " and the content ID of voice data be recorded.

(5) then, personal computer 100 is corresponding to the permission in the track descriptor copyright management information of the voice data that moves " verification output " number of times subtracts increment 1 from the predetermined times that is provided with in step (3).In this example, permission " verification output " to become (3-1=2) inferior for number of times.

(6) then, wherein disk drive device 1 (not shown) of loading tray 90 is verified the track descriptor corresponding to the voice data that moves.For example, be reproduced at the deleted link information TINFn of step (1) and PINFn and deposit in or create again.As a result, the track descriptor corresponding to the voice data that moves is proved.When corresponding to the track descriptor of the voice data that moves when step (1) is deleted, the track descriptor is created again.Alternatively, the respective track descriptor in personal computer 100 can be sent to disk drive device 1 and be recorded to dish.

, can think after (6) in execution in step (1) " verification output " sequence of process finishes.Therefore, voice data can be copied to personal computer 100 from coiling 90, and the copyright time and the work protected and user of voice data are reduced simultaneously.

Preferably the replicate run that is used for voice data in step (1) to (6) is applied to the user records dish 90 with disk drive device voice data.

When by " verification output " and voice data by " the verification input " time, the control information of personal computer 100 search voice datas and track descriptor, for example, copyright management information, enter a judgement according to voice data that obtains and control information, and carry out " the verification input " operation.

10. about the structure of software

The example of structure according to the software of the file transfer system of embodiments of the invention is finished in Figure 47 demonstration.In this manual, term " system " is meant a plurality of members' logic gathering, no matter whether they are comprised in the box.

Jukebox is used in 300 personal computers that are installed in as content server.Jukebox use 300 be provided for storage such as peel off from CD (compact disk) and/or from such as the storehouse of content voice data, that create storage of the network download of internet with operate the user interface in this storehouse.In addition, jukebox is used being connected of 300 control personal computers 100 and disk drive device 1.The function of above-mentioned common software can be comprised in jukebox and use in 300.In other words, software shown in Figure 47 such as the hard disk drive of personal computer 100, and transmits data between the dish 90 as second recording medium, and return data between them in the recording medium as first recording medium.

Jukebox is used 300 and is had database management module 301.Database management module 301 is managed dish ID and one group of storehouse in dish ID database of sign dish 90 relatively or is coiled the ID list.According to embodiments of the invention, UID is used as dish ID.The back is with data of description database management module 301.The group of management and dish ID database or dish ID list.

Jukebox uses 300 by 302 operations of the security module on the OS 303 that is installed in personal computer 100.Security module 302 has the licence of regulation in SDMI (Secure Digital Music Initiative is crossed the threshold) and is obedient to module (LCM).LCM carries out the authentication process between jukebox application 300 and disk drive device 1.In addition, the consistance of security module 302 inspection content ID and UID.All contents exchange between jukebox application 300 and disk drive device 1 by security module 302.

In addition, MD of future generation drives firmware 320 and is installed in disk drive device 1.MD of future generation drives the software that firmware 320 is operations of console panel drive unit 1 itself.Personal computer 100 console panel drive units 1, and utilize and to drive 304 by MD device of future generation and drive communicating by letter and disk drive device 1 swap data between firmware 320 and the OS 303 at MD of future generation.

MD of future generation drives cable that firmware 320 can be by for example connecting personal computer 100 and disk drive device 1 or such as the communication interface 310 of network, and is updated in the version of personal computer 100 1 sides.

In addition, jukebox is used 300 and is recorded in such recording medium such as CD-ROM (compact disk-ROM (read-only memory)), and is provided for it.When recording medium was loaded onto personal computer 100 and carries out predetermined operation, for example being recorded in, the jukebox application 300 of recording medium was stored in for example hard disk drive of personal computer 100.Alternatively, jukebox is used 300 (or jukebox is used 300 setter) and can be provided to personal computer 100 by the network such as the internet.

Then, with data of description database management module 301.The storehouse can be provided with group.When content was relevant with group according to suitable criterion, content can be classified.According to embodiments of the invention, the dish ID of sign dish 90 can carry out relevant with group.As dish ID, can use above-mentioned UID.

Then, with reference to Figure 48 A and Figure 48 B, the database by database management module 301 management of jukebox application 300 is described roughly.The example of structure of Figure 48 A display panel ID database or dish ID list.In dish ID database or dish ID list, the management relatively of dish ID and group.As real example more, shown in Figure 48 A, dish ID and group, about by the information of the capacity of the dish 90 of dish ID sign and " verification exports " reservation information is relevant.In addition, dish ID can be relevant with other attributes, for example the kind of autograph book title, autograph book, artist--name, data (compression) form, the date that registers to database, content supplier or the like.

The structure in Figure 48 A and Figure 48 B data presented storehouse only is the example of embodiments of the invention.Therefore, the invention is not restricted to these structures.

" dish ID " is the district of audio disk ID in district shown in Figure 48 A.Dish ID is the identifier that coils 90 unique recording mediums for each.

District's " group name claims " is to be used for the district that group name claims.The user can use 300 with jukebox and group name is set claims.Alternatively, the user can use jukebox application 300 group names that provide to claim.The user can use sight, such as appointment, drive, or the like; Use the artist, such as singer, performer or the like; Use attribute, such as allusion, jazz or the like; Like item with the user, such as nearest content or the like group name is set and claims.

District's " dish capacity " is the district of information that is used for the capacity of relevant dish 90.The information of the capacity of relevant dish 90 is the information of for example coiling 90 remaining capacity.By this information, the user can know the data volume that can be recorded on the dish 90.

District's " reservation information " is relevant " verification output " the district of information of reservation.Relevant " verification output " the information of reservation can represent " verification output " and whether be retained and represent its content by " verification output " and dish." verification output " whether be retained, can be determined by the data in district's " reservation information " or predetermined bit.When using predetermined bit, " verification output " can be preserved for also the not new dish of registration.To its execution " verification output " dish can be identified with the relevant information that is registered in the dish ID in district's " reservation information ".Alternatively, about being used for " verification input " reservation information can be used for " verification output " and the identical mode of reservation be registered to district's " reservation information ".

On the other hand, the information of dish ID and related content can with carry out relevant as content ID for the unique content recognition of content number.Figure 48 B shows the example of structure of carrying out relevant content ID database or content ID list with the information of related content.Content ID database or content ID list are dynamically created according to for example coiling the ID database or coiling the ID list by database management module 301.

District " content ID " is the district that is used for content ID.Content ID has for example data length of 128 bits.When content was obtained by jukebox application 300 and is stored in the storehouse, security module 302 was specified a content ID to content.The content that is stored in the storehouse can be discerned by content ID.

District shown in Figure 48 B " dish ID " is identical with the district shown in Figure 48 A " dish ID ".Therefore, dish ID database or dish ID list and content ID database or content ID list can carry out relevant with dish ID.By dish ID and content ID, the information of related content is managed uniquely.

In addition, content ID can carry out relevant with the attribute and the dish ID of content.In the example shown in Figure 48 B, dish ID is registered in district " dish ID ".CO (verification output) number of times of permission is registered in district's " CO number of permission ".The size of content, promptly data volume is registered in district's " size ".The size of content is relevant with the content ID that is stored in district " content ID ".Certainly, the information of other types also can be carried out relevant with content ID.

On Figure 48 B, dish ID carries out relevant with the content ID that is registered to the storehouse.Alternatively, content ID can carry out relevant with dish ID.Alternatively, content ID can carry out relevant with group.Alternatively, permission " verification output " number of times can carry out relevantly with dish ID.Alternatively, the storehouse can be managed according to first above-mentioned management method or second management method that is used for music data.

Then, embodiments of the invention are described.According to embodiment, when obtaining new voice data, " verification output " be retained by above-mentioned software.Phrase " obtains new content " and is meant not only " peeling off new content " and " use new content, for example reappear new content ".

Figure 49 and Figure 50 show the example according to the operation of the software of embodiment.Then, with reference to Figure 49 and 50, this embodiment of the present invention is described.

Figure 49 shows the operation that is used to peel off new content and stores the software of the content of peeling off.Peel off is to read such as the numerical data of content from the original recording medium such as music CD and extract numerical data as the file that is used for computing machine.

When content was stripped from, it was acquired in personal computer 100.In addition, dish ID database or dish ID list are upgraded by database management module 301.As a result, the new content of being stripped from and being acquired, be registered such as the dish information of dish ID, group, dish capacity or the like.In addition, content ID database or content ID list are updated.As a result, the new content of being stripped from and being acquired, such as content ID, dish ID, size, permission " verification output " content information of number of times or the like is registered.

In the present embodiment, new content is stripped from and is stored.Alternatively, present embodiment can be applied to the situation that content wherein is downloaded from network by the electronic music distribution services of using such as the network of internet.Therefore, content can be from the server on the network, is provided such as the electronic music Distributor from the internet (rather than such as CD or DVD recording medium), from downloaded, and is stored in database.

As shown in figure 49, when peeling off beginning, or carrying out when peeling off, puing question to, whether providing user interface to keep to the user " verification output " (step S200).For example, display message on the screen of personal computer 100 " you keep " verification output "? ", so that the request user makes the answer that is/denys.

At step S201, determine result in the answer of step S200.When at step S201, the result of answer represents that the user will not keep " verification output " time, that is, the result of answer is a "No", peels off normally and carries out.Finish peel off after, processing procedure finishes.

At step S201, " verification output " be retained.In other words, when the result who answers is "Yes", inquiry dish ID database or dish ID list (at step S202).After this, the request user specifies it by user interface " verification output " dish (at step S203) that is retained.

The content of being stripped from is it " verification output " content that is retained.All contents, that is, whole autograph book, can by " verification output ".Alternatively, each song can by " verification output ".Its " verification output " content that is retained can be the content of being stripped from not only, and be the content that has been registered in the storehouse.Therefore, splitting time can be used effectively.

When keeping for each autograph book " verification output " time, content can be identified with dish ID or content ID.When keeping for each song " verification output " time, content can the two be identified with coiling ID and content ID.

When obtaining new content for personal computer 100 by peeling off etc., the information of relevant new content is added to above-mentioned dish ID database or dish ID list.At this moment, inquire the user by user interface: " do you register to database to new dish? (be/not) ", so that obtain for registration about the information of the dish of new content and the permission of content information from him or she.

For its execution " verification output " dish be identified with coiling ID.In above-mentioned dish ID database or dish ID list, dish ID and group are managed relatively.Therefore, to its execution " verification output " dish can be with group identification.Its " verification output " dish that is retained can use such as the information of the group relevant with dish ID designated by the user.

Therefore, at step S203, content ID carries out relevant with dish ID.For with content ID content identified " verification output " be retained.

In addition, optional option, for example " new dish " can be used in for the new group that is not registered to dish ID database or dish ID list and carry out " verification output ".When " new dish " selected conduct is carried out it " verification output " dish the time, the data of new dish can be set up.

When what it was carried out " verification output " content that is retained and to its execution " verification output " dish when step S203 is designated, to its execution " verification output " content size with to its execution " verification output " and the recordable capacity of dish compare so that determine when carrying out " verification output " time it is carried out " verification output " and the capacity whether enough (step S204) of dish.When to its execution " verification output " dish when being registered in dish ID database or dish ID list, relevant dish ID database or coil the dish 90 in the ID list capacity information and to its execution " verification exports " the size of content compare.When to its execution " verification output " dish when being new dish, the recordable capacity that the type by dish, data (compression) form or the like obtain coiling.The capacity of the dish that obtains with to its execution " verification output " and the size of content compare.

Whether when the result who determines at step S204 represents that recording capacity is not enough, that is, the result who determines is a "No", by user interface inquiry user, keep " the verification input ", so that recording capacity is not inadequate (at step S206).For example, display message on the screen of personal computer 100 " you keep " verification input "? ", so that the request user makes the answer that is/denys.

At step S207, determine result in the answer of step S206.When the result in the answer of step S207 represents that the user will not keep " the verification input " time, that is, the result of answer is a "No", normally carries out and peels off.Peel off finish after, processing procedure finishes.Alternatively, before flow process turned back to step S204, the request user reduced " verification output " number, or change its execution " verification output " dish.

When the result in the answer of step S207 represents that the user will keep " the verification input ", that is, and when the result of answer is "Yes", " the verification input " be retained (at step S208).Be used to be retained " verification input " content and destination be used to be retained " verification output " and identical mode be retained.Yet, be used to be retained " verification input " content to be used to be retained " verification output " and opposite direction flow.

" verification input " be retained after, flow process turns back to step S204.Can carry out and to infer " the verification input ".Infer " verification input " have deleted with its content from disk drive device 1 " the verification input " identical effect, and content by " the verification input ".Therefore, about being used for " verification input " reservation, the processing procedure from step S206 to step S208 is unessential.In this case, when the result who determines at step S204 represents that recording capacity is inadequate, that is, when the result who determines is "No", peels off and normally carried out.Peel off finish after, processing procedure finishes.Before flow process turns back to step S204, can remind and ask the user to reduce " verification output " number, or change its execution " verification output " dish.

When the result in the answer of step S204 represents recording capacity is enough, that is, when the result who determines is "Yes", " verification output " be retained (at step S205).For example, expression is for content " verification output " be retained information, to its execution " verification output " dish or the like be registered to district's " reservation information " of dish ID database or dish ID list.Database management module 301 is new building ID database or dish ID list more.Verification output as a result, " " be retained.

" verification output " be retained and after reservation finished, processing procedure finished.When peeling off when being retained and since dish be registered in that dish ID in dish ID database or the dish ID list is identified or new dish designated, disk drive device 1 does not need to be connected to personal computer 100.

Peel off finish after, when " verification output " when being retained, the state of disk drive device 1 and the state that is loaded onto the dish on it are examined.When the condition that these states satisfy to keep, carry out for keeping " verification output " processing procedure.When wherein the disk drive device 1 of loading tray (be abbreviated as PD: when mancarried device) after execution is peeled off, being connected, when wherein the disk drive device 1 of loading tray be when newly connecting after execution is peeled off, maybe when another dish of dish 90 usefulness substitutes, shown in Figure 50, for what keep " verification output " processing procedure automatically performed.
