Description

  The present invention relates to a recording / reproducing apparatus capable of recording / reproducing a storage medium on which content data such as music data is recorded and a method thereof.

Conventionally, desired image data is recorded in association with content data such as music data recorded on a storage medium such as a CD (Compact Disc), an MD (Mini Disc: magneto-optical disc), and a hard disk. That is done.
For example, when song data is recorded in units of albums on a storage medium, album jacket photos and the like are recorded in association with each other.
Alternatively, it is possible to associate image data captured by the user with a digital still camera or the like.
By recording image data in association with music data in this way, it becomes possible to present an image image of the music to the user, for example, when loading music information stored in the storage medium, There are merits such as making music selection intuitive and increasing entertainment.

Then, for example, it is conceivable to adopt a technique in which the captured image data is recorded on a storage medium in association with the desired music data by following an instruction of an application for editing music data.

As a related prior art, the following patent document shows a configuration for automatically editing video data and music data on the recording / reproducing apparatus side.
JP 2003-125346 A

  However, for example, in the method using a personal computer or the like for associating music data and image data as described above, the user performs at least an operation for starting an application for editing music data and an operation for capturing a captured image. It is necessary to perform a plurality of operations such as a music data designation operation to be associated with the captured image. Further, at this time, there is a possibility that such an operation may be complicated for a user who is not familiar with a personal computer or the like.

  Also, even when a captured image can be directly captured by a recording / playback device without going through a personal computer, the user must be forced to perform multiple operations, such as an operation for capture and an operation for selecting music data to be associated. become.

Furthermore, when the music data and the image data are associated with each other as described above, it is conceivable that the user cannot recognize the contents only by presenting the title name of the music. In such a case, before associating the image data, the user listens to some pieces of music and recognizes the contents, and then performs an operation for associating the image data with the music again.
This further increases the number of operations.

Therefore, in the present invention, in view of the above problems, the recording / reproducing apparatus is configured as follows.
That is, first, reproduction means capable of reproducing data from a storage medium stored so that at least track-unit content data including audio data is managed in units of groups, and recording capable of recording data on the storage medium Means.
In addition , image capturing means for capturing image data based on the captured image based on the operation is provided.
Further, it is determined whether or not the operation for the image capturing means is performed for the first time for the group to which the content data of the track unit being reproduced in the reproducing means belongs, and as a result, the operation is performed. in case where it is that which has been done in the first image data captured by the image capturing means is recorded in correspondence to said group to which content data of the track unit belongs in the reproduction and to a recording control means for controlling said recording means so that.

In the present invention, the recording / reproducing apparatus is configured as follows.
That is, reproduction means capable of reproducing data from a storage medium stored so that at least track-unit content data including audio data is managed in group units, and recording means capable of recording data on the storage medium; Is provided.
In addition, image capturing means for capturing image data based on the captured image based on the operation is provided.
Further, the operation for the image capturing means is performed during the reproduction of the track unit content data with a title that matches the title assigned to the group to which the track unit content data being reproduced belongs. And if the operation is determined to be performed during the reproduction of the content data of the track unit with the matching title, the image capturing means image data captured by said on so that a recording control means for controlling said recording means so as to be recorded in correspondence to said group to which content data of the track unit belongs in the reproduction.

According to the recording / reproducing apparatus and recording / reproducing method of the present invention described above, the group to which the captured image belongs to the content data being automatically reproduced according to, for example, the timing at which the captured image is captured based on a user operation. It is recorded in association with.

As described above, according to the present invention, for example, when a captured image is captured based on a user operation, the captured image is automatically associated with the group to which the content data being reproduced belongs , and thus recorded. By simply performing an operation for capturing a captured image, the captured image data can be recorded on a storage medium in association with the group to which the content data being reproduced belongs .
That is, according to the present invention, the operation for recording in association with an imaging image can be a very simple, Ru can be greatly reduced user interaction burden.

Further, as described above, in the present invention, since the captured image is recorded in association with the group to which the content data being reproduced belongs , for example, as described above, reproduction is performed for confirmation of the content content. Also in the case of performing, the user can perform the association between the group to which the content data belongs and the captured image only by performing an operation for capturing the captured image during reproduction.
In other words, after the reproduction for content confirmation as in the prior art, it is not necessary to perform an operation for again associating, easy operation for only pairs応付 also IMAGING image in this respect FIG. It will be.

Hereinafter, the best mode for carrying out the invention (hereinafter referred to as an embodiment) will be described.
FIG. 1 is a block diagram showing an internal configuration example of a recording / reproducing apparatus 1 as an embodiment.
As an example, the recording / reproducing apparatus 1 according to the embodiment is a recording / reproducing apparatus for a mini-disc (MD) disc that is a magneto-optical disc on which data recording is performed by a magnetic field modulation method. However, not only music mini-discs that are already in widespread use, but also high-density recording that can be used for storage of various data for computer use (also called next-generation discs). It is a playback device.

Further, the recording / reproducing apparatus 1 of this example is a device capable of data communication with an external device such as a personal computer (or network) 50, for example.
For example, the recording / reproducing apparatus 1 can function as an external storage device for the personal computer 50 by being connected to the personal computer 50 via a transmission path 51 such as a USB cable. In addition, music or various data is downloaded via a personal computer 50 or connected to the network by providing a function that can be directly connected to the network, and the disc loaded in the storage unit 2 in the recording / playback apparatus 1 is downloaded. It can also be saved.

On the other hand, the recording / reproducing apparatus 1 functions as an audio device, for example, without being connected to the personal computer 50 or the like. For example, music data input from another audio device or the like can be recorded on a disc, and music data recorded on the disc can be reproduced and output.
That is, the recording / reproducing apparatus 1 of this example is an apparatus that can be used as a general-purpose data storage device by being connected to the personal computer 50 or the like, and can also be used as an audio recording / reproducing device by itself.

Here, an outline of a next-generation disk by magneto-optical recording, which is supported by the recording / reproducing apparatus 1 of this example, will be described.
First, such a next-generation disc uses a FAT (File Allocation Table) system as a file management system to record and reproduce content data such as audio data so that compatibility with current personal computers can be achieved. Is.
Further, by improving the current MD system, such as an error correction method and a modulation method, the data recording capacity is increased and the data reliability is increased.

  The next-generation disc recording / playback format includes the next-generation MD1 specification that uses the same disc as the disc used in the current MD system, and the disc and outer shape used in the current MD system. Is the same, but the specification of the next generation MD2 is proposed in which the recording density in the linear recording direction is increased and the recording capacity is further increased by using the magnetic super-resolution (MSR) technology.

In the current MD system, a magneto-optical disk having a diameter of 64 mm housed in a cartridge is used as a recording medium. The disc has a thickness of 1.2 mm, and a center hole having a diameter of 11 mm is provided at the center thereof. The cartridge has a length of 68 mm, a width of 72 mm, and a thickness of 5 mm.
The shape of the disc and the shape of the cartridge are all the same in the specifications of the next generation MD1 and the specification of the next generation MD2. Regarding the start position of the lead-in area, the next-generation MD1 specification and the next-generation MD2 specification disc start from 29 mm and are the same as the disc used in the current MD system.
That is, compatibility with the conventional MD system on the outer shape is ensured.

  Regarding the track pitch, in the next generation MD2, it is considered to be 1.2 μm to 1.3 μm (for example, 1.25 μm). On the other hand, in the next generation MD1, which uses a disk of the current MD system, the track pitch is set to 1.6 μm. The next-generation MD1 is 0.44 μm / bit and the next-generation MD2 is 0.16 μm / bit. The redundancy is 20.50% for both the next generation MD1 and the next generation MD2.

In the next-generation MD2 specification disk, the recording capacity in the linear density direction is improved by using a magnetic super-resolution technique. In the magnetic super-resolution technology, when a predetermined temperature is reached, the cut layer becomes magnetically neutral, and the magnetic wall transferred to the recording layer is transferred, so that a minute mark can be seen in the beam spot. It is a thing using what becomes.
Specifically, in a next-generation MD2 specification disc, a magnetic layer serving as a recording layer for recording information, a cutting layer, and a magnetic layer for reproducing information are stacked on a transparent substrate. The cutting layer is an exchange coupling force adjusting layer. When the temperature reaches a predetermined temperature, the cut layer becomes magnetically neutral, and the domain wall transferred to the recording layer is transferred to the reproducing magnetic layer. As a result, minute marks can be seen in the beam spot. At the time of recording, a minute mark can be generated by using a laser pulse magnetic field modulation technique.

  Further, in the disc of the next-generation MD2 specification, in order to improve detrack margin, crosstalk from the land, wobble signal crosstalk, and focus leakage, the groove is deepened and the groove is sharpened. In the disc of the next generation MD2 specification, the groove depth is, for example, 160 nm to 180 nm, the groove inclination is, for example, 60 degrees to 70 degrees, and the groove width is, for example, 600 nm to 700 nm.

  As for the optical specifications, the laser wavelength λ is 780 nm and the numerical aperture NA of the objective lens of the optical head is 0.45 in the specification of the next generation MD1. Similarly, in the specification of the next generation MD2, the laser wavelength λ is 780 nm, and the aperture ratio NA of the optical head is 0.45.

  As the recording method, the groove recording method is adopted for both the MD1 specification and the MD2 specification. That is, the groove (groove on the disk surface of the disk) is used as a track for recording and reproduction.

Further, as an error correction coding method, convolutional codes based on ACIRC (Advanced Cross Interleave Reed-Solomon Code) are used in the current MD system, but in the specifications of the next generation MD1 and the next generation MD2, RS-LDC is used. A block-complete code combining (Reed Solomon-Long Distance Code) and BIS (Burst Indicator Subcode) is used.
By adopting a block completion type error correction code, a linking sector becomes unnecessary. In an error correction method combining LDC and BIS, an error location can be detected by BIS when a burst error occurs. Using this error location, erasure correction can be performed by the LDC code.

As an addressing method, a wobbled groove method is used in which a single spiral groove is formed and wobbles as address information are formed on both sides of the groove. Such an address system is called ADIP (Address in Pregroove).
The specification of ADIP is the same as that of the current MD system. In the current MD system, a sector consisting of 2352 bytes is used as an access unit for recording and reproduction, whereas in the specifications of the next generation MD1 and next generation MD2. 64 Kbytes are used as recording / reproducing access units (recording blocks).
In the current MD system, a convolutional code called ACIRC is used as an error correction code, whereas in the specifications of the next generation MD1 and the next generation MD2, a block completion type code combining LDC and BIS is used. Is used.
Therefore, in the specification of the next generation MD1 that uses the disk of the current MD system, the handling of the ADIP signal is made different from that in the current MD system. In the next-generation MD2 specification, the specification of the ADIP signal is changed so as to match the specification of the next-generation MD2.

  Regarding the modulation method, EFM (8 to 14 Modulation) is used in the current MD system, whereas in the specifications of the next generation MD1 and the next generation MD2, RLL (1, 7) PP (RLL; Run Length Limited, PP; Parity Preserve / Prohibit rmtr (repeated minimum transition run length)) (hereinafter referred to as 1-7pp modulation) is employed. The data detection method is a Viterbi decoding method using a partial response PR (1, 2, 1) ML in the next generation MD1 and a partial response PR (1, -1) ML in the next generation MD2. .

  The disk drive system is CLV (Constant Linear Verocity), and the linear velocity is 2.7 m / second in the next-generation MD1 specification, and 1.98 m / second in the next-generation MD2 specification. In the specification of the current MD system, it is 1.2 m / second for a 60-minute disk and 1.4 m / second for a 74-minute disk.

In the specification of the next generation MD1, which uses the disk used in the current MD system as it is, the total data recording capacity per disk is about 300 Mbytes (when an 80-minute disk is used). By changing the modulation method from EFM to 1-7pp modulation, the window virgin is changed from 0.5 to 0.666, and in this respect, a 1.33 times higher density can be realized.
Further, since the error correction method is a combination of BIS and LDC from the ACIRC method, the data efficiency is improved, and in this respect, 1.48 times higher density can be realized. Overall, a data capacity of about twice that of the current MD system was realized using exactly the same disk.

  In contrast, in the next-generation MD2 specification disk using magnetic super-resolution, the recording density is further increased in the linear density direction, and the total data recording capacity is about 1 GB.

  The data rate is 4.4 Mbit / sec in the next generation MD1, and 9.8 Mbit / sec in the next generation MD2.

FIG. 2A shows the configuration of the next-generation MD1 disk.
The next-generation MD1 disc is a disc of the current MD system. That is, a dielectric film, a magnetic film, a dielectric film, and a reflective film are laminated on a transparent polycarbonate substrate. Further, a protective film is laminated thereon.
In the next-generation MD1 disk, as shown in FIG. 2A, a P-TOC (pre-mastered TOC (Table Of Contents)) area is provided in the lead-in area on the inner periphery of the disk. This is a pre-mastered area as a physical structure, and control information and the like are recorded as P-TOC information by embossed pits.

The outer periphery of the lead-in area in which the P-TOC area is provided in this way is a recordable area (a magneto-optical recording area), which is a recordable / reproducible area in which a groove is formed as a guide groove for a recording track. ing. A U-TOC (user TOC) is provided on the inner periphery of the recordable area.
The U-TOC in this case has the same configuration as the U-TOC used for recording disc management information in the current MD system. For confirmation, the U-TOC is management information that can be rewritten according to the order of tracks (audio tracks / data tracks), recording, erasing, etc. in the current MD system. The start position, end position, and mode are managed for the parts constituting the track.

  An alert track is provided on the outer periphery of the U-TOC. The alert track is a warning track in which a warning sound indicating that this disc is used in the next generation MD1 system and cannot be reproduced by a player of the current MD system is recorded.

FIG. 2B shows the configuration of the recordable area of the disc of the next generation MD1 specification.
As shown in FIG. 2B, a U-TOC and an alert track are provided at the beginning (inner circumference side) of the recordable area. In the area including the U-TOC and the alert track, the data is modulated by EFM and recorded so that it can be reproduced by a player of the current MD system.
An area where data is modulated and recorded by 1-7pp modulation of the next generation MD1 system is provided on the outer periphery of the area where data is modulated and recorded by EFM modulation. A region where data is modulated and recorded by EFM and a region where data is modulated and recorded by 1-7pp modulation are separated by a predetermined distance, and a guard band is provided.
Since such a guard band is provided, it is possible to prevent the occurrence of problems by mounting a disc of the next generation MD1 specification on the current MD player.

A DDT (Disc Description Table) area and a secure track are provided at the beginning (inner circumference side) of an area where data is modulated and recorded by 1-7pp modulation. The DDT area is provided for performing a replacement sector process for a physically defective sector (recording block).
A unique ID (UID) is further recorded in the DDT area. The UID is an identification code unique to each recording medium, and is based on a predetermined random number, for example.
The secure track stores information for protecting the content.

Furthermore, a FAT (File Allocation Table) area is provided in an area where data is modulated and recorded by 1-7pp modulation. This FAT area is an area for managing data in the FAT system.
The FAT system performs data management conforming to the FAT system used in general-purpose personal computers. The FAT system performs file management by a FAT chain using a directory indicating entry points of files and directories at the root and a FAT table in which FAT cluster connection information is described.

  In such a next-generation MD1 specification disc, the above-described U-TOC area includes information on the start position of the alert track and information on the start position of the area where the data is recorded by 1-7 modulation. It will be recorded.

Here, when the next-generation MD1 disc having the above-described configuration is mounted on the player of the current MD system, the U-TOC area is read, and the position of the alert track is known from the U-TOC information, and the alert track is Accessed and alert track playback starts. In the alert track, a warning sound is recorded indicating that this disc is used in the next generation MD1 system and cannot be reproduced by a player of the current MD system.
This warning sound informs that this disc cannot be used with the current MD system player.
Note that the warning sound in this case may be a warning in a language such as “cannot be used with this player”. Of course, a buzzer sound may be used.

  On the other hand, when a next-generation MD1 disc is loaded into a player compliant with the next-generation MD1, the U-TOC area is read, and the start of the area in which data is recorded by 1-7pp modulation from the U-TOC information The position is known, and the above-described DDT, secure track, and FAT area are read. As described above, in the 1-7pp modulation data area, data management is performed by the FAT system, not by the U-TOC.

Next, FIG. 3A shows the configuration of the next-generation MD2 disk.
Also in this case, the disk is formed by laminating a dielectric film, a magnetic film, a dielectric film, a reflective film on a transparent polycarbonate substrate, and a protective film on the upper layer.
In the case of the next-generation MD2 disc, control information is recorded by an ADIP signal in the lead-in area on the inner periphery of the disc as shown in the figure.
Next-generation MD2 discs are not provided with P-TOC by embossed pits in the lead-in area, and instead, control information by ADIP signals is used. The recordable area starts from the outer periphery of the lead-in area, and is a recordable / reproducible area in which a groove is formed as a guide groove for a recording track. In this recordable area, data is modulated and recorded by the 1-7 pp modulation method.

Here, whether it is the next generation MD1 or the next generation MD2 can be determined from, for example, lead-in information.
That is, if a P-TOC due to an emboss pit is detected in the lead-in, it can be determined that the disc is a current MD or next-generation MD1 disc. If control information based on the ADIP signal is detected in the lead-in and no P-TOC due to the embossed pit is detected, it can be determined that the next generation MD1.
The discrimination between the next generation MD1 and the next generation MD2 is not limited to such a method. It is also possible to discriminate from the phase of the tracking error signal between on-track and off-track. Of course, a disc identification detection hole or the like may be provided.

As the configuration of the recordable area of the next-generation MD2 specification disc, as shown in FIG. 3B, an area where data is modulated and recorded by the 1-7 modulation method is formed. A DDT area and a secure track are provided at the beginning (inner circumference side) of an area where data is modulated and recorded by the 1-7 modulation method.
Also in this case, the DDT area is an area for performing a replacement sector process on a physically defective sector (recording block). The UID described above is recorded in the DDT area. Further, in this case, information for protecting the content is stored in the secure track.

  A FAT area is provided in an area where data is modulated and recorded by 1-7pp modulation. The FAT area is an area for managing data in the FAT system. The FAT system performs data management conforming to the FAT system used in general-purpose personal computers.

In such a next-generation MD2 disc, as can be seen from the figure, no U-TOC area is provided. In other words, the next-generation MD2 disc is assumed to be used only by a player compliant with the next-generation MD2.
When the next-generation MD2 disc is loaded, the DDT, secure track, and FAT area at a predetermined position are read, and data management is performed using the FAT system.

  In order to deal with the next generation disc as described above, the recording / reproducing apparatus 1 of this example shown in FIG. 1 includes a storage unit 2 having the configuration shown in FIG. It is supposed to be played back.

  In FIG. 4, in the storage unit 2, the loaded disk 40 is rotationally driven by the spindle motor 29 by the CLV method. The disc 40 is irradiated with laser light from the optical head 19 during recording / reproduction.

In this case, as the disk 40, a current MD specification disk, a next generation MD1 specification disk, and a next generation MD2 specification disk may be mounted. The linear velocity will be different.
For this reason, the spindle motor 29 is rotated in accordance with different linear velocities corresponding to the loaded disks 40.

  The optical head 19 performs a high level laser output for heating the recording track to the Curie temperature during recording, and a relatively low level laser output for detecting data from reflected light by the magnetic Kerr effect during reproduction. . For this reason, although not shown in detail here, the optical head 19 is equipped with a laser diode as a laser output means, an optical system composed of a polarizing beam splitter, an objective lens, and the like, and a detector for detecting reflected light. Yes. The objective lens provided in the optical head 19 is held so as to be displaceable in the radial direction of the disk and in the direction of contacting and separating from the disk, for example, by a biaxial mechanism.

A magnetic head 18 is disposed at a position facing the optical head 19 with the disk 40 interposed therebetween. The magnetic head 18 performs an operation of applying a magnetic field modulated by the recording data to the disk 40.
Although not shown, a sled motor and a sled mechanism are provided to move the entire optical head 19 and the magnetic head 18 in the radial direction of the disk.

  In the case of the next-generation MD2 disk, the optical head 19 and the magnetic head 18 can form minute marks by performing pulse drive magnetic field modulation. In the case of a current MD disc or a next-generation MD1 disc, the magnetic field modulation method is used.

  In addition to the recording / reproducing head system using the optical head 19 and the magnetic head 18 and the disk rotation driving system using the spindle motor 29, the storage unit 2 includes a recording processing system, a reproducing processing system, a servo system, and the like.

  In the recording processing system, in the case of a disc of the current MD system, at the time of recording an audio track, error correction coding is performed by ACIRC, data is recorded by being modulated by EFM, and the next generation MD1 or next generation MD2 is recorded. In some cases, a part for performing error correction coding by a combination of BIS and LDC and modulating and recording with 1-7pp modulation is provided.

  In the playback processing system, EMD demodulation and ACIRC error correction processing during playback of the current MD system disc, and data detection using partial response and Viterbi decoding during playback of the next generation MD1 or next generation MD2 system disc A portion for performing 1-7 demodulation based on the above and error correction processing by BIS and LDC is provided.

  Further, there are provided a part for decoding an address based on an ADIP signal of the current MD system or the next generation MD1, and a part for decoding an ADIP signal of the next generation MD2.

Information detected as reflected light by laser irradiation of the optical head 19 on the disk 40 (photocurrent obtained by detecting the laser reflected light with a photodetector) is supplied to the RF amplifier 21.
The RF amplifier 21 performs current-voltage conversion, amplification, matrix calculation, and the like on the input detection information, and reproduces a reproduction RF signal, a tracking error signal TE, a focus error signal FE, and groove information (track on the disk 40) as reproduction information. ADIP information recorded by wobbling) is extracted.

When reproducing the disc of the current MD system, the reproduced RF signal obtained by the RF amplifier is processed by the EFM demodulator 24 and the ACIRC decoder 25.
That is, the reproduced RF signal is binarized by the EFM demodulator 24 to be converted into an EFM signal sequence, EFM demodulated, and further subjected to error correction and deinterleave processing by the ACIRC decoder 25. That is, at this time, the ATRAC compressed data state is entered.

  At the time of reproducing the disk of the current MD system, the selector 26 is selected on the B contact side, and the demodulated ATRAC compressed data is output as reproduced data from the disk 40.

  On the other hand, when reproducing the next generation MD1 or next generation MD2 disc, the reproduction RF signal obtained by the RF amplifier is processed by the RLL (1-7) PP demodulator 22 and the RS-LDC decoder 25. That is, the reproduced RF signal is detected by the RLL (1-7) PP demodulator 22 by means of data detection using PR (1, 2, 1) ML or PR (1, -1) ML and Viterbi decoding. ) Reproduced data as a code string is obtained, and RLL (1-7) demodulation processing is performed on this RLL (1-7) code string. Further, the RS-LDC decoder 23 performs error correction and deinterleave processing.

  When reproducing the next-generation MD1 or next-generation MD2 disc, the selector 26 is selected on the A contact side, and the demodulated data is output as reproduction data from the disc 40.

The tracking error signal TE and the focus error signal FE output from the RF amplifier 21 are supplied to the servo circuit 27, and the groove information is supplied to the ADIP demodulator 30.
The ADIP demodulator 30 performs band limitation on the groove information by a bandpass filter to extract a wobble component, and then performs FM demodulation and biphase demodulation to demodulate the ADIP signal.
The thus-demodulated ADIP address, which is absolute address information on the disk, is supplied to the system controller 8 shown in FIG. The system controller 8 executes necessary control processing based on the ADIP address.
The groove information is supplied to the servo circuit 27 for spindle servo control.

The servo circuit 27 generates a spindle error signal for CLV servo control, for example, based on an error signal obtained by integrating the phase error with the reproduction clock (PLL clock at the time of decoding) with respect to the groove information.
Further, the servo circuit 27 performs various servo control signals (tracking control signals) based on a spindle error signal, a tracking error signal supplied from the RF amplifier 21, a focus error signal, a track jump command, an access command, etc. from the drive controller 31. , A focus control signal, a thread control signal, a spindle control signal, etc.) are generated and output to the motor driver 28. That is, various servo control signals are generated by performing necessary processing such as phase compensation processing, gain processing, and target value setting processing on the servo error signal and command.

The motor driver 28 generates a required servo drive signal based on the servo control signal supplied from the servo circuit 27. The servo drive signal here includes a biaxial drive signal for driving the biaxial mechanism (two types of focus direction and tracking direction), a sled motor drive signal for driving the sled mechanism, and a spindle motor drive signal for driving the spindle motor 29. It becomes.
With such a servo drive signal, focus control and tracking control for the disk 40 and CLV control for the spindle motor 29 are performed.

When recording audio data on the disc of the current MD system, the selector 16 is connected to the B contact, so that the ACIRC encoder 14 and the EFM modulator 15 function.
In this case, the compressed data supplied from the cache memory 3 shown in FIG. 1 as recording data is subjected to interleaving and error correction code addition by the ACIRC encoder 14 and then EFM modulation by the EFM modulation unit 15.
The EFM modulation data is supplied to the magnetic head driver 17 via the selector 16, and the magnetic head 18 applies a magnetic field to the disk 40 based on the EFM modulation data, thereby recording an audio track.

On the other hand, when recording data on the next-generation MD1 or next-generation MD2 disc, the selector 16 is connected to the A contact, and the RS-LDC encoder 12 and the RLL (1-7) PP modulation unit 13 function. Become. In this case, high-density data from the cache memory 3 is subjected to interleaving and RS-LDC error correction code addition by the RS-LDC encoder 12, and then RLL (1-7) PP modulation unit 13 performs RLL (1 -7) Modulation is performed.
Then, the recording data as the RLL (1-7) code string is supplied to the magnetic head driver 17 via the selector 16, and the magnetic head 18 applies a magnetic field based on the modulation data to the disk 40, thereby data tracks. Is recorded.

The laser driver / APC 20 causes the laser diode to perform a laser emission operation during reproduction and recording as described above, but also performs a so-called APC (Automatic Laser Power Control) operation.
That is, although not shown, a detector for laser power monitoring is provided in the optical head 19, and the monitor signal is fed back to the laser driver / APC 20. The laser driver / APC 20 compares the current laser power obtained as the monitor signal with the set laser power and reflects the error in the laser drive signal, so that the laser power output from the laser diode is , It is controlled to stabilize at the set value.
As the laser power, values as reproduction laser power and recording laser power are set by the system controller 8 in a register in the laser driver / APC 20.

  Each of the above operations (access, various servo, data write, and data read operations) is executed based on an instruction from the system controller 8 shown in FIG.

Returning to FIG. 1, the overall configuration of the recording / reproducing apparatus 1 of this example will be described.
In FIG. 1, a cache memory 3 is a cache memory that buffers data recorded on the disk 40 by the storage unit 2 having the above configuration or data read from the disk 40 by the storage unit 2, for example, D- It consists of RAM.
Writing / reading data to / from the cache memory 3 is controlled by a task activated in the system controller (CPU) 8.

  The USB interface 4 performs processing for data transmission when connected to the personal computer 50 through a transmission path 51 as a USB cable, for example.

The input / output processing unit 5 performs processing for input / output of recording / playback data, for example, when the recording / playback apparatus 1 functions alone as an audio device.
The input / output processing unit 5 includes, for example, an analog audio signal input unit such as a line input circuit / microphone input circuit, an A / D converter, and a digital audio data input unit as an input system. It is assumed that an ATRAC compression encoder / decoder is provided.
Further, as an output system, a digital audio data output unit and analog audio signal output units such as a D / A converter and a line output circuit / headphone output circuit are provided.

Moreover, the recording / reproducing apparatus 1 of this example is provided with a camera block 10 as shown in the figure.
The camera block 10 is based on an imaging unit including an imaging element such as a camera lens or a CCD (Charge Coupled Device), CMOS (Complementary Metal-Oxid Semiconductor) sensor, and in this case, based on a captured image obtained in the imaging unit. A signal processing circuit system for generating image data is also included. The captured image data generated by the camera block 10 is transferred based on the control of the system controller 8.

The system controller 8 performs overall control in the recording / reproducing apparatus 1 and communication control with the connected personal computer 50.
The ROM 8a shown in the figure stores an operation program for the system controller 8, fixed parameters, and the like. Particularly in the case of this example, the ROM 8a stores a program for realizing the operation as the recording / reproducing apparatus 1 of this example as will be described later with reference to FIGS.

The RAM 8b is used as a work area by the system controller 8 and is a storage area for various necessary information.
For example, various management information and special information read from the disk 40 by the storage unit 2 are stored. Music track management information such as the above-described P-TOC data, U-TOC data, and FAT data is stored in the RAM 8b.
The RAM 8b temporarily holds the image data generated in the camera block 10 as will be described later.

  The cache management memory 9 is composed of, for example, an S-RAM, and stores information for managing the state of the cache memory 3. The system controller 8 controls data cache processing while referring to the cache management memory 9.

The display unit 6 displays various information to be presented to the user based on the control of the system controller 8. For example, operation information, mode status, name information of data such as music, track number, time information, and other information are displayed.
In this example, when the disk 40 is a next generation disk, for example, it is assumed that image data is stored in association with the music data on the disk 40, and the display unit 6 Based on the control of the system controller 8 at the time of loading or reproduction of 40, the image data correlated in this way is also displayed.

In the operation unit 7, various operation buttons, a jog dial, and the like are formed as various operators for user operations. In particular, as an operator in this case, a shutter button for instructing the camera block 10 to capture a captured image is provided.
The user gives a required operation instruction to the recording / reproducing apparatus 1 by operating the operation unit 7. The system controller 8 performs a predetermined control process based on the operation information input by the operation unit 7.

The configuration of the recording / reproducing apparatus 1 in FIG. 1 is an example. For example, the input / output processing unit 5 may include an input / output processing system corresponding to video data as well as audio data.
Further, the connection with the personal computer 50 is not USB, but another external interface such as IEEE 1394 may be used.
Moreover, although the case where the camera block 10 was incorporated was mentioned as an example, it is good also as a structure which takes in captured image data from the digital still camera connected externally, for example. Alternatively, for example, it is configured to be able to capture captured image data in cooperation with an external device such as a personal computer 50 connected via the USB interface 4 and a camera system configured by a camera device connected to the external device. May be.

In this example, image data based on the captured image obtained by the camera block 10 when the shutter button of the operation unit 7 is operated by the configuration of the recording / reproducing apparatus 1 as described above is stored in the storage unit 2. Are recorded on the disk 40 in association with the music data of the disk 40 loaded in the disk.
In this example, when the captured image data is recorded in association with the music data as described above, the music data being reproduced is displayed in response to the operation of the shutter button described above during the reproduction of the music data. On the other hand, the captured image data is recorded in association with each other.

  Note that such recording of image data on the disk 40 is assumed only for the next generation disk, and therefore the following description will be made when the disk 40 as the next generation disk is loaded in the recording / reproducing apparatus 1. It is assumed that

Processing operations to be performed by the system controller 8 shown in FIG. 1 in order to realize the operation of this example will be described with reference to the flowchart of FIG.
The processing operation shown in this figure is executed by the system controller 8 based on a program stored in the ROM 8a shown in FIG.
In FIG. 6, the system controller 8 monitors the operation on the shutter button provided in the operation unit 7 by the processing in step S <b> 101 shown in the figure.
When operation information corresponding to such an operation of the shutter button is input from the operation unit 7, a determination process is performed as to whether or not music data is currently being reproduced in step S102.
If a negative result is obtained in step S102 that the music data is not currently being reproduced, for example, the processing operation is terminated as shown in the figure. That is, in this case, the captured image data and the music data are not associated with each other.
If a positive result is obtained in step S102 that the music data is currently being reproduced, the process proceeds to step S103.

  In step S103, the captured image data is temporarily stored. That is, the image data generated by the camera block 10 in response to the shutter button operation described above is held in, for example, the RAM 8b.

In the subsequent step S104, the track number (No.) of the music track currently being reproduced is recognized.
In step S105, based on the recognized track number information, a process of writing the captured image data previously held in a predetermined area on the disk 40 is performed.
Further, in the subsequent step S106, processing for updating the contents of the management information is executed so that the captured image data written in this way is associated with the music data of the recognized track number.

By executing such processing, the image data written on the disc 40 in step S105 is managed as being associated with the track being reproduced at the previous step S102. It becomes like this.
Thereafter, when the disc 40 is loaded, for example, the image data recorded in this way is displayed on the display unit 6 as an image corresponding to the music track being reproduced. It becomes possible.

In the processing of step S105 described above, as an area on the disk 40 to which the captured image data is to be written, a storage area is provided on the management information side for music data, and a storage area is provided for the music file itself. You could think so.
5A and 5B show a simple data structure in the case where such image data as image data is stored on the music data management information side, and storage of image data in a music file. It is a figure which shows the simple data structure in case an area | region is provided.
For example, in the case shown in FIG. 5A, as the processing in step S105, for example, writing is performed in the storage area for image data provided for each track number in the management information as shown in the figure. .
In the case shown in FIG. 5B, as the processing in step S105, writing may be performed to the image data storage area provided on the music file side as shown in the figure.

Regarding the processing in step S105, according to the above description, the writing of the captured image data to the disk 40 is performed in real time in parallel with the reproduction operation. The write timing may be after the read data read from the disk 40 is cached in the cache memory 3.
Alternatively, it may be performed at other timing, such as after the music track that was being reproduced is stopped.

As described above, in the recording / reproducing apparatus 1 of this example, the captured image data is recorded on the disk 40 in association with the music data being reproduced in response to the shutter button operation performed during the reproduction of the music data. Since it did in this way, matching of the captured image data with music data is realizable by one operation.
That is, the recording / reproducing apparatus 1 of this example enables the user to associate the captured image data with the music data by a very simple operation of only the shutter button operation.

In addition, since the captured image is recorded in association with the music data being reproduced in this way, the user performs an operation for imaging during the audition even when performing the audition for confirming the music contents. The captured image can be associated with the music data simply.
Depending on this, there is no need to perform the association operation again after confirming the music content by trial listening as in the past. The operation for attaching and recording is simplified.

By the way, according to the processing operation shown in FIG. 6, the captured image data can be associated only in units of tracks.
However, in this case, for example, it may be possible to record the captured image data in association with a group including a plurality of music tracks including a music track being reproduced, such as an album unit.
For example, the next-generation disc described above has a large capacity, so that it is possible to record music data for a plurality of album units. Then, in the situation where music data in units of a plurality of albums is stored in this way, it is conceivable that captured images are recorded in association with these individual groups.

In this manner, when image data is associated with a group composed of a plurality of music tracks, for example, in units of albums, for example, the processing operation shown in the flowchart of the following FIG. 7 is performed. That's fine.
First, in FIG. 7 as well, in this case as well, the system controller 8 performs the processing of steps S201 and S202 shown in the figure to monitor the shutter button operation and determine whether or not music data is being reproduced. . In step S203, a process for temporarily holding a captured image is performed.

In this case, in the subsequent step S204, a process for recognizing the track number and group information for the music track being reproduced is executed.
In this case, the management of the group in units of albums is performed based on the management information about the music data in the FAT data. Therefore, in the processing of step S204, the group information is managed in this way. Recognize by referring to the information.

In subsequent step S205, a determination process is performed as to whether or not the shutter button operation recognized in step S201 is the first shutter button operation.
That is, as the first shutter button operation, it is determined whether or not the shutter button operation is performed for the first time with respect to a music track included in the group including the music track being reproduced.

In this step S205, when a negative result is obtained that the shutter button operation recognized in step S201 is not the first shutter button operation, the process shown in FIG. By executing the processing equivalent to steps S105 → S106, the processing for recording the previously stored image data in association with the music track being reproduced is executed.
That is, when it is not the first shutter button operation, the captured image data is associated with the track being reproduced.

On the other hand, if an affirmative result is obtained in step S205 that the operation is the first shutter button operation, first, a process of writing captured image data to a predetermined area on the disk is executed by the process of step S208.
In this case, in the subsequent step S209, processing for updating the contents of the management information is executed so that the written image data is associated with the group to which the music track being reproduced belongs.
Thus, in response to the first shutter button operation, the captured image data is recorded on the disc 40 as being associated with the group to which the track being reproduced belongs.

Thus, depending on the processing operation shown in FIG. 7, when the shutter button operation performed on the music track being played is the first time for the music track in the same group, the captured image data is Recorded as associated with the entire group.
On the other hand, if the shutter button operation performed on the music track being played is for the second time or later on the music track in the same group, the captured image data is associated with the music track being played. It will be recorded.
In other words, this allows the user to selectively associate the captured image with each music track and associate with the group to which the track being played belongs, only by operating the shutter button.

  Also, according to such a method, for example, even when a captured image is associated only once with a piece of music data of a certain group, this captured image can be set as a group image. There is a merit.

  As described above, in the example of FIG. 7, whether the captured image is used for the track or the group is determined depending on whether or not the first shutter button operation is performed on the group. Other methods may be adopted, such as using an image taken during reproduction of a track with the same title name (especially an album title name) as a group.

  Further, in this example, the case where the content data stored in the disc 40 is music data has been described as an example. However, in the present invention, for example, when other content data such as video data is stored. Can also be suitably applied.

  Also, in this example, the case where the recording / reproducing apparatus of the present invention is applied to a configuration corresponding to MD is taken as an example, but it corresponds to other storage media such as CD (Compact Disc), hard disk, semiconductor memory device, etc. The present invention can be preferably applied to such a configuration.
