Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to adjustment of reproduction signal quality of recorded data when recording data on a write-once optical disc and a rewritable optical disc.

[0002]

2. Description of the Related Art Recently, an optical disk capable of recording data,
In addition to cost reductions for optical disk recording devices, data recording software, computers, etc., it is possible to record large amounts of data, so audio (music) data, computer data, image (still image) data, moving image data, etc. Optical discs are used for recording / playback of various data and for backup. As the recording optical disk capable of recording data, for example, a write-once optical disk capable of recording data only once such as a CD-R or a DVD-R,
CD-RW, DVD-RW, DVD + RW, DVD-R
There is a rewritable optical disk capable of rewriting data such as AM. In the optical disc recording apparatus for recording data on these optical discs, conventionally, a write strategy (Write
Strategy) and other device recording parameters related to the quality of the reproduced signal of recorded data are automatically set to optimum values. When using the optical disk recording apparatus, the user can set whether or not to enable the function of automatically decreasing the recording speed to the reproduction limit when the setting of the recording speed is not appropriate.

[0003]

When music data of a press CD (CD manufactured by a stamper, for example, CD-DA) is copied to an optical disc capable of recording the above data, the sound quality is slightly different. It is known to become a thing. Since the music data recorded on the optical disc is digital data, the sound quality does not seem to be the same as the original music data when played back, but in reality, due to differences in the quality of the reproduced signal such as β and jitter, it may be necessary for experts or audiophiles to The sound quality of music data is different at the level that can be understood by.

At present, although the cause of this difference is not clearly known, it is known that the sound quality changes when the device recording parameters related to the reproduced signal quality are changed.

However, since the conventional optical disc recording apparatus automatically sets each parameter to the optimum value as described above, the data to be recorded on the optical disc is computer data even if it is music data. However, the data was recorded with the same optimum parameters. This optimum parameter is a set value that is most unlikely to cause an error when data is reproduced, but it cannot always be said that the optimum sound quality is obtained when recording music data. Therefore, in order to obtain a good sound quality when reproducing the music data recorded on the optical disk, it is necessary to set the optimum parameters for the music data separately from those for the computer.

However, when recording data on an optical disc by a conventional optical disc recording apparatus, the user cannot set a parameter indicating the reproduction signal quality of the recorded data. For example, when recording music data on a CD-R, it has been impossible to adjust the β value to a desired value in order to improve the reproduction sound quality of the music data. Therefore, even a beginner can easily record data on the optical disk, but the parameter indicating the reproduction signal quality cannot be adjusted to a desired setting, which makes the specification unsatisfactory for advanced users.

Further, the material of the optical disk (especially the recording layer)
Is different depending on the type, maker, model number, etc., and thus the write strategy and recording speed setting of the optical disc recording apparatus are different depending on the maker, model number, etc. of the optical disc. Therefore, the music data of the press CD is CD-
When copied to R, the reproduced sound of the press CD and the reproduced sound of the CD-R may be different in sound quality due to the difference in the manufacturer of the CD-R and the difference in the optical disk recording device for recording the music data. .

Further, the optical disk capable of recording data differs in the maximum recording speed capable of recording and the recording speed capable of recording with the best signal quality depending on the manufacturing time, model number and the like. For example, since an old type optical disc having a low maximum recordable speed has a relatively thick recording film, it is possible to perform recording with good reproduction signal quality in a low speed region such as 1 × speed or 2 × speed. On the other hand, since the recording film of the new type optical disc having a high maximum recordable speed is relatively thin, it is possible to perform recording with good reproduction signal quality in a higher speed region such as 4 × speed or 8 × speed. Therefore, if the optical disk does not support the recording speed set by the user by mistake, some optical disk recording apparatuses have a function of automatically changing the maximum recording speed according to the optical disk. However, the changed maximum recording speed is based on the signal quality limit, and does not select a recording speed with good signal quality such as jitter. Therefore, when recording music data, it cannot be said that the recording speed automatically set by this function can record music data with good sound quality. Therefore, there is a problem that the specifications are unsatisfactory for users who desire good sound quality such as audiophiles.

Due to such a problem, audiophiles purchase an optical disk recording device suitable for recording music data, and have a good compatibility with the recording of the music data by the optical disk recording device, and the music data can be recorded with good sound quality. For example, a recordable optical disk was selected and purchased, and the optimum writing speed was adjusted for each selected optical disk. However, such work imposes a burden on the user on cost and labor.

A CD recorded by an optical disk recording device
-R is not always reproduced by the optical disk recording device, and when an optical disk recorded by the optical disk recording device is listened to by a CD player, reproduction signal quality by the optical disk recording device is good when reproduced by another CD player. The sound quality was not always good.

Therefore, the present invention has been made to solve the above problems, and an object thereof is an optical disk whose reproduction signal quality can be adjusted by the user or automatically according to the data to be recorded. A recording method, an optical disk recording device, and an optical disk recording program are provided.

The operation at the time of recording data on the optical disc D in the optical disc recording apparatus 1 configured as described above will be described. The inventors conducted various experiments and studies in order to obtain good sound quality when copying music data from a source disc to a recordable optical disc. As a result, the music data recorded on the source disc and the music data on the copy destination optical disc are reproduced so that the reproduction signal waveforms, that is, the reproduction signal qualities, are substantially the same, and the music data is recorded on the recordable optical disc at the copy destination. It was found that recording the same as above, a sound quality similar to that of the source disc can be obtained.

Therefore, in the first embodiment of the present invention, when copying the data recorded on the optical disc, the reproduction signal quality of the data-recorded optical disc (copy source optical disc) is measured, and the reproduction signal quality is determined. In order to obtain substantially the same reproduction signal quality, the device recording parameter related to the reproduction signal quality is set to a predetermined value, and the data is recorded on the recording optical disc of the copy destination.

For example, when reading music data from a press CD (music CD) or a recorded CD-R, the reproduction signal quality is measured to obtain signal quality parameters such as β value and asymmetry. Next, based on the measured signal quality parameters, device recording parameters related to the reproduced signal quality (for example, target β value when performing OPC) so that the reproduced waveform of the original music data is reproduced in substantially the same manner. Is set to a predetermined value. Then, the music data recorded on the copy source optical disk is recorded on the recording optical disk with the above setting. It should be noted that the reproduced signal quality is measured when reproducing the test data test-recorded by a plurality of laser powers by the OPC performed before the main recording, and the measured signal quality parameter and the reproduced signal quality are related. The relationship with the device recording parameters may be obtained and stored in the storage unit 26, and the device recording parameters may be adjusted. Further, the relationship between the signal quality parameter indicating the reproduction signal quality and the device recording parameter related to the reproduction signal quality is obtained in advance by experiments or the like, stored in the storage unit 26, and stored in the storage unit 2 at the time of recording.
It is advisable to read from 6 and adjust the device recording parameters.

As a result, the reproduction signal waveform and reproduction signal quality of the music data of the copy source optical disk and the music data of the copy destination optical disk become substantially the same, and the sound quality of the music data can be adjusted substantially the same. . The data is not limited to music data and may be other data.

Further, these signal quality parameters are not completely independent, and when one parameter is changed, other parameters may be changed accordingly.

The device recording parameters relating to the reproduction signal quality at the time of recording the data are parameters for determining the reproduction signal quality of the data at the time of recording the data on the optical disk, for example, the write strategy and the data are recorded. At this time, there are laser power for irradiating the optical disk, target β value in OPC and running OPC, focus balance, tracking balance, recording speed and the like.

Further, when the reproduction signal quality of the copy source has an inner and outer circumference difference, recording is performed while changing the apparatus recording parameter at the recording position (radial position or time), and a substantially similar reproduction signal quality inner and outer circumference difference is obtained. You can put it on.

FIG. 3 is an example of a flowchart for explaining the first embodiment of the present invention. Here, the signal quality parameter representing the reproduced signal quality will be described below as a β value. First, the user uses a source disk such as a press CD (music CD) or a recorded CD-R to record the optical disk recording device 1
And the operation unit 27 is operated to reproduce the music data (s1). The system control unit 16 includes an operation unit 27
When receiving the signal from, the servo is automatically adjusted to read the music data of the source disc. The servo circuit 13 outputs control signals for the focus servo mechanism and the tracking servo mechanism to the optical pickup 10. It also outputs a rotation control signal to the spindle motor 11.
The system control unit 16 outputs a predetermined signal for controlling the laser power to the laser power control circuit 20. The laser power control circuit 20 outputs a control signal for the laser driver 19 and outputs a power control signal for the laser light emitted from the laser diode to the optical pickup 10 from the laser driver 19. Laser light of a predetermined laser power is emitted from the laser diode of the optical pickup 10, and return light (reflected light) of the laser light is emitted from the optical pickup 10.
Is received by the light receiving element, converted into an electric signal, and output to the RF amplifier 12 (s2).

The signal of the music data amplified by the RF amplifier 12 is decoded by the decoder 15 and output to the data storage circuit 25, and the data storage circuit 25 stores the music data of the source disc (s3).

The signal amplified by the RF amplifier 12 is output to the signal quality detecting circuit 24, and the signal quality detecting circuit 24 measures the reproduced signal quality of the music data of the source disc (s4). The measurement result is the system control unit 16
And is stored in the built-in RAM (s5). When all the music data of the source disc is stored in the data storage circuit 25, the system control unit 16 displays on the display unit 28 that the storage of the music data / playback signal quality of the source disc is completed (s6).

Upon confirming this display, the user takes out the source disc from the optical disc recording device 1 and sets an optical disc capable of recording data in the optical disc recording device 1 instead (s7).

The system control unit 16 performs automatic servo adjustment of the optical disc for recording data, and outputs a predetermined signal to the servo circuit 13, the laser power control circuit 20, and the encoder 1.
Output to 7. The optical pickup 10 irradiates the optical disc with laser light, the return light is received by the light receiving element, converted, and output to the RF amplifier 12. This signal is
ATIP in the signal output to the address detection circuit 14
(Absolute Time In Pre-groove) Information is read to determine the type of optical disc. Then, the address of the optical disc is detected and output to the system control unit 16 (s8). The system control unit 16 reads the data stored in advance in the storage unit 26 based on the optical disc identification information. Then, the apparatus recording parameters are set based on this data and the measurement result of the reproduced signal quality stored in the RAM (s9).

Subsequently, the system control unit 16 confirms whether or not there is a problem in the setting of the apparatus recording parameter, and at the same time, determines the optimum laser power by the OPC.
(Optimum Power Control). That is, a predetermined signal is sent to the servo circuit 13, the laser power control circuit 20, the encoder 17, based on the set device recording parameter.
It outputs to the strategy circuit 18. Optical pickup 10
Records and reproduces a test signal on the PCA. This return light is output to the signal quality detection circuit section 24 via the RF amplifier 12 (s10). Reproduction signal quality detection circuit section 24
Detects the reproduction signal quality of the test signal and outputs it to the system control unit 16 (s11). The system control unit 16
The reproduction signal quality data output from the reproduction signal quality detection circuit unit 24 is compared with the reproduction signal quality of the source disc stored in the RAM (s12). As a result of the comparison, if there is a problem that a substantially equal reproduction signal quality cannot be obtained, the device recording parameters of s9 are changed, and s9 to s1 are again set.
Execute 2. If there is no problem, the music data read from the source disc stored in the data storage circuit 25 is recorded on the optical disc by setting the device recording parameter. That is, the music data is output from the data storage circuit 25, and a predetermined signal is output to the servo circuit 13, the laser power control circuit 20, the encoder 17, and the strategy circuit 18 based on the set device recording parameters. Then, the optical pickup 10 irradiates the recording optical disc with a laser beam corresponding to the music data to record the music data (s13). When the recording of the music data is completed, the system control unit 16 displays on the display unit 28 that the recording is completed (s14). Then, the process ends.

The data previously stored in the storage unit 26 is a device recording parameter relating to the quality of the reproduced signal when recording the data, and corresponds to the disc identification information.
There are a write strategy and a target β value in OPC. Further, data representing the relationship between the signal quality parameter indicating the reproduction signal quality corresponding to the disc identification information and the device recording parameter related to the reproduction signal quality is previously obtained by an experiment or the like and stored in the storage unit 26. It is even better to keep it. By adjusting the device recording parameters based on the reproduction signal quality of the source disc and the relationship obtained in advance, it is possible to record with the reproduction signal quality substantially similar to that of the source disc.

The OPC determines the optimum laser power by recording and reproducing test data with a plurality of laser powers and checking the quality of the reproduced signal. At this time, by measuring the reproduction signal quality under a plurality of recording conditions, the relationship between the signal quality parameter indicating the reproduction signal quality of the optical disc and the device recording parameter related to the reproduction signal quality may be obtained. Further, instead of changing the laser power for recording in the OPC, the device recording parameter such as the write strategy may be changed to obtain the relationship with the device recording parameter related to the reproduction signal quality. By adjusting the device recording parameters based on the relationship obtained here and the reproduced signal quality of the source disc, it is possible to record with the reproduced signal quality substantially similar to that of the source disc. Alternatively, the adjustment conditions may be verified again by returning to s9.

Next, a second embodiment of the present invention will be described. In the second embodiment of the present invention, the user can set the signal quality parameter representing the reproduction signal quality of the data to be recorded on the recording optical disc of the optical disc recording device to any value. That is, when music data is recorded on the optical disc by the optical disc recording device, it is possible to set the signal quality parameter indicating the reproduction signal quality according to the user's preference, so that the sound quality that the user feels good can be set. Is provided. The details will be described below.

As the signal quality parameter indicating the reproduced signal quality, in addition to the β value and the asymmetry, the HF modulation degree and the HF
Amplitude, HF reflectance, average reflectance, crosstalk, jitter, deviation, effective length, etc. Further, these signal quality parameters are not completely independent, and when one parameter is changed, other parameters may be changed accordingly.

The device recording parameters relating to the reproduction signal quality at the time of recording the data are parameters for determining the reproduction signal quality of the data at the time of recording the data on the optical disk, for example, the write strategy and the data are recorded. At this time, there are laser power for irradiating the optical disk, target β value in OPC and running OPC, focus balance, tracking balance, recording speed and the like.

However, when the above apparatus recording parameters are changed, the degree to which the above signal quality parameters are replaced differs depending on the type of disc. Therefore, when the user changes the device recording parameter, it becomes difficult to obtain a desired reproduction signal quality.
In the present invention, the user can set the signal quality parameter indicating the reproduction signal quality according to his / her preference, and the device side sets the signal quality parameter indicating the reproduction signal quality on the optical disc and the device recording parameter related to the reproduction signal quality. From the above relationship, the device recording parameter is adjusted based on the set arbitrary signal quality parameter.

Further, there are cases where the data recorded on the recording optical disk cannot be reproduced depending on the reproduction signal quality parameter value, and the target reproduction signal quality cannot be achieved unless it is outside the settable range of the device recording parameter. When the user tries to select such setting of the reproduction signal quality parameter value, a warning may be displayed on the display unit or the setting range of the reproduction signal quality parameter value may be limited.

FIG. 4 is a display example for setting a signal quality parameter indicating a reproduced signal quality to be displayed on the display section. As shown in FIG. 4A, for example, a graph may be displayed on the display unit and the user may select a set value from this graph. Alternatively, as shown in FIG. 4B, a table in which patterns of signal quality parameters representing reproduced signal qualities are set may be displayed, and set values may be selected from the table. Further, as shown in FIG. 4C, a gauge that allows the user to set an arbitrary value may be displayed on the display unit so that the user can select a desired set value. In this case, for example, when the set β value is changed, the parameters of C1 error, jitter, and sound are changed accordingly.

As described above, since the user can set the signal quality parameter indicating the reproduced signal quality to an arbitrary value, for example, when recording music data on the optical disc,
The desired sound quality can be set, and the cost and time for selecting the conventional optical disk recording device or recording optical disk can be reduced.

Further, when the recording device and the reproducing device are different, it is possible to set the sound quality according to the characteristics of the reproducing device. Even if the recording device has a good signal quality, the sound quality is poor when reproduced by the reproducing device. It can be reduced.

Further, in the optical disc recording apparatus of the second embodiment, a changeover switch for changing over whether the apparatus automatically sets the signal quality parameter indicating the reproduced signal quality or the user sets an arbitrary value. Should be provided. In this case, the initial value (default value) is set when the device automatically sets the parameter that indicates the quality of the reproduced signal.
Need to be set.

FIG. 5 is an example of a flow chart for explaining the second embodiment of the present invention. The data to be recorded on the optical disk is assumed to be stored in the data storage circuit 25 in advance. First, the user operates the changeover switch of the operation unit 27 to select the mode in which the user sets the signal quality parameter indicating the reproduced signal quality. Then, the recording optical disk is set in the optical disk recording apparatus 1 (s31). The system control unit 16 automatically adjusts the servo to determine the type of the set recording optical disk. It outputs a predetermined signal to each of the servo circuit 13, the laser power control circuit 20, and the encoder 17. With these signals, laser light is emitted from the optical pickup 10 to the recording optical disc, and the returned light is received by the light receiving element of the optical pickup 10, converted into an electric signal, and output to the RF amplifier 12. This signal amplified by the RF amplifier 12 is output to the address detection circuit 14, the ATIP information (address information) is detected by the address detection circuit 14, and output to the system control unit 16 (s
32). The system control unit 16 determines the type of the optical disk based on this signal, and calls the data pattern of the signal quality parameter indicating the reproduction signal quality from the storage unit 26. Then, this data is converted into, for example, a table and displayed on the display unit 28 (s33). The user operates the operation unit 27.
Is operated to select a desired value of the signal quality parameter from the table displayed on the display unit 28 and input the value (s
34). The system control unit 16 adjusts the device recording parameter related to the reproduced signal quality based on the value of the selected signal quality parameter (s35). Adjustment is performed in the storage unit 2
6, the device recording parameter is adjusted based on the relationship between the signal quality parameter indicating the reproduced signal quality on the optical disc and the device recording parameter related to the reproduced signal quality, and the set arbitrary signal quality parameter. You may do it. Or OP explained in the next stage
In C, the device recording parameter is adjusted based on the relationship between the signal quality parameter indicating the reproduced signal quality on the optical disc and the device recording parameter related to the reproduced signal quality, and the set arbitrary signal quality parameter. Good.

Then, the servo circuit 1 is used to perform OPC.
3, a predetermined signal is output to each of the laser power control circuit 20 and the encoder 17 to perform test recording. The test recording is reproduced and the return light is the optical pickup 10.
The light receiving element receives the light and converts it into an electric signal, and the RF amplifier 12 outputs the amplified signal to the signal quality detection circuit section 24 (s36). The system control unit 16
The optimum laser power is set based on the signal output from the signal quality detection circuit unit 24. Then, the system control unit 16 causes the data storage circuit 25 to output the data to be recorded on the recording optical disc (s37). This data is irradiated as laser light from the optical pickup 10 via the encoder 17, the strategy circuit 18, and the laser driver 19, and the data is recorded on the optical disc (s3).
8). When the data recording is completed, the optical disk recording device 1 displays the completion of the data recording on the display unit 28, and ends the processing (s39).

Next, a third embodiment of the present invention will be described. In the third embodiment of the present invention, the signal quality indicating the reproduction signal quality according to the type of data to be recorded and the format format, for example, CD-DA (audio data) or CD-ROM MODE-1 (data for personal computer). The parameter is automatically set by the optical disk recording apparatus, that is, the setting suitable for each data type is selected. The device recording parameter is adjusted and set according to the setting, and data is recorded on the recording optical disc. That is, when the data is recorded on the optical disc by the optical disc recording device, the environment for setting the pattern of the signal quality parameter regarding the reproduction signal quality according to the data is provided.

The details will be described below. In the third embodiment, when the optical disc recording apparatus reads the data recorded on the optical disc of the copy source, or when the recording data is transmitted from the outside to the data storage circuit, the system control unit 16 performs the recording. Determine the type of data for use. And
The system control unit 16 sets a signal quality parameter indicating the reproduced signal quality based on the determination result. For example, when the recording data is computer data, the parameters relating to the reproduction signal quality are automatically set so that an error does not occur at the time of reproduction, and when the recording data is music data, the sound quality is optimized. The device recording parameters are automatically adjusted and set according to the setting, and the data is recorded on the recording optical disc.
Alternatively, the device recording parameter may be directly and automatically set by storing the relationship between the reproduction signal quality and the device recording parameter in advance. In this way, the optical disc recording apparatus automatically discriminates even if the user does not care about the type of data to be recorded, which is effective for beginners.

At this time, in the case of computer data, it is advisable to pay attention to the C1 error value as the signal quality parameter indicating the reproduced signal quality. FIG. 6A is a diagram showing the relationship between the C1 error value and the β value when data is recorded on the optical disc. Since the relationship between the C1 error and β is a quadratic curve, the recording device parameters are set so that the C1 error value becomes the bottom value of this quadratic curve. On the other hand, in the case of music data, it is good to pay attention to the jitter value. FIG. 6 (B)
FIG. 6 is a diagram showing a relationship between jitter and β. The recording device parameters are set so that the jitter value is at the bottom of this quadratic curve.

In the case of music data, the HF modulation degree (I
3 / I11) may be focused on and the point at which the value of the HF modulation degree becomes large may be aimed at. At this time, the device recording parameter may be adjusted such that the write strategy is adjusted to increase the length of the short pit (particularly 3T).

However, for example, when recording music data on an optical disc, some users attach great importance to recording the data on the optical disc without error without particular attention to the sound quality. Therefore, in such a case, although the data to be recorded on the optical disc is music data, the signal quality parameter regarding the reproduced signal quality may be set to be suitable for computer data. Therefore, the user can select the pattern of the signal quality parameter regarding the reproduced signal quality corresponding to the data (the pattern for audio, the pattern for computer data, etc.).

FIG. 7 shows an example of setting the signal quality parameter indicating the quality of the reproduced signal according to the type of data. In consideration of the above parameters, as shown in FIG. 7, a signal quality parameter indicating a reproduction signal quality such as a β value may be displayed according to the type of data, the type of optical disc, and the like. Further, device recording parameters such as write strategy may be displayed.

FIG. 8 is an example of a flow chart for explaining the third embodiment of the present invention. The data to be recorded on the optical disk is assumed to be stored in the data storage circuit 25 in advance. First, the user operates the optical disc recording apparatus 1
The recording optical disk is set in (s51). The system control unit 16 outputs a predetermined signal to each of the servo circuit 13, the laser power control circuit 20, and the encoder 17 in order to determine the type of the set recording optical disc. With these signals, laser light is emitted from the optical pickup 10 to the recording optical disc, and the returned light is received by the light receiving element of the optical pickup 10, converted into an electric signal, and output to the RF amplifier 12. This signal amplified by the RF amplifier 12 is output to the address detection circuit 14, the ATIP information (address information) is detected by the address detection circuit 14, and output to the system control unit 16 (s
52).

Then, by operating the changeover switch of the operation unit 27, whether the apparatus automatically sets the signal quality parameter pattern regarding the reproduced signal quality according to the data to be recorded or the user sets it. Select (s
53). When the device automatically sets the parameters,
The system control unit 16 calls a signal quality parameter related to the reproduced signal quality of the storage unit 26 from the type of data stored in the storage circuit 25 and the type of disk. (S5
4). The system control unit 16 automatically sets the parameter value based on the value of the selected parameter. Or
The signal quality parameter relating to the reproduced signal quality of the storage unit 26 and the device recording parameter are called and automatically set (s55). Then, a predetermined signal is output to each of the servo circuit 13, the laser power control circuit 20, and the encoder 17 to perform the OPC. With these signals, the optical pickup 10 irradiates the recording optical disc with laser light, and test recording is performed. The portion is reproduced, and the returned light is received by the light receiving element of the optical pickup 10, converted into an electric signal, and output to the RF amplifier 12 (s5
6). The amplified signal is output from the RF amplifier 12 to the signal quality detection circuit unit 24. The signal quality 6 sets the optimum laser power based on the signal output from the signal quality detection circuit unit 24 (s57). Then, the system control unit 16 causes the data storage circuit 25 to output the data to be recorded on the recording optical disc. This data is used by the encoder 17, the strategy circuit 18, the laser driver 1
Laser light is emitted from the optical pickup 10 via 9 to record data on the optical disc (s58). When the data recording is completed, the optical disc recording apparatus 1 displays on the display unit 28 that the data recording is completed,
The process ends (s59).

On the other hand, when the setting is made by the user, the setting of the signal quality parameter relating to the reproduced signal quality suitable for each data type is converted into a table and displayed on the display unit 28. At this time, the device recording parameters may be displayed. The operation unit 27 is operated to select which kind of data is to be recorded by setting the signal quality parameter indicating the reproduction signal quality suitable for the data type (s60). Based on this selection, the system control unit 16 sets the device recording parameter indicating the signal quality (s61), and executes the processes from s56.

Next explained is the fourth embodiment of the invention. In the fourth embodiment of the present invention, data recording is performed by setting device recording parameters related to the reproduced signal quality so that the signal quality during reproduction fluctuates, that is, changes and fluctuations occur.

Details will be described below. In order to change or fluctuate (change) the signal quality at the time of reproduction, for example, the signal quality may change at a constant frequency. Also, the recording may be performed so that the signal quality changes at random frequencies. Further, the center frequency may be set so that the signal quality changes irregularly.

In order to change or fluctuate the signal quality during reproduction, for example, the recording power may be changed. Also, the write strategy may be changed. Further, the focus balance may be changed.

However, if the signal quality during reproduction is changed or fluctuates by the above method, fluctuation components that are not desired to be included in the signal may actually be included due to wobble, disc eccentricity, disc surface fluctuation, etc. There is. Therefore, by changing the device recording parameter by the following method, it is possible to add the original fluctuation while canceling the fluctuation component that is not desired to be added.

That is, the parameter for canceling the fluctuation component is set so that the fluctuation component which should not be placed can be canceled. FIG. 9 is a graph showing waveforms of fluctuation components and parameters for canceling the fluctuation components. As shown in FIG. 9, by setting the recording power as an apparatus recording parameter so as to correspond to the absolute value of the frequency of the disc eccentricity, it is possible to cancel the fluctuation caused by the disc eccentricity.

Further, by placing an arbitrary frequency as the base frequency on the signal, it is possible to add a fluctuation component of a desired frequency to the recorded data. For example, the frequency (about 10 Hz) of the α-wave component, which is a kind of human brain waves, is suitable. That is, it is known that human brain waves include α-waves, β-waves, γ-waves, and the like, and when the α-wave component increases, the human becomes in a relaxed state. Further, when listening to music fluctuating at the frequency of the α-wave component (about 10 Hz), it is said that the brain wave has many α-wave components in tune with this frequency. Therefore, by placing fluctuations in the frequency (about 10 Hz) of the α-wave component on the music data recorded on the optical disc, it is expected that the person listening to the reproduced music data can relax.

As described above, when the data to be recorded is music data, by changing or fluctuating the reproduction signal quality at the time of reproduction, a new audible feeling and a new psychological effect can be produced.
