Each CD stored in the CD reproducing unit 1 is distinguished by a disk number such as disk 1, disk 2,... According to the storage position. Also, the CD playback unit 1 associates the disc number, total time, number of tracks, and the like with each other, and outputs them to the controller 8 as CD track information. Further, the CD playback unit 1 plays back the music data recorded on the CD at a normal speed (normal playback) or plays back at a high speed (high speed playback), and outputs it to the MD recording / playback unit 2 and the DAC 3.
[0028]
The MD recording / reproducing unit 2 is a spindle motor that rotates the MD at a predetermined speed, a magnetic head that records information (data) on the MD, and a laser beam of a predetermined wavelength that is irradiated to the MD, and information (data) recorded on the MD. Is constituted by an optical pickup for reading out, a magnetic head, a thread motor for moving the optical pickup in the radial direction of the MD, a DSP (Digital Signal Processor), and the like. The MD recording / reproducing unit 2 obtains the number of music data (number of tracks) recorded in the MD from the TOC information recorded in the MD set at a predetermined position, and outputs it to the controller 8 as MD track information. To do. The MD recording / reproducing unit 2 records the music data supplied from the CD reproducing unit 1 on the MD. Specifically, the MD recording / playback unit 2 records the music data normally played by the CD playback unit 1 at a normal speed (normal recording), and records the music data played by the CD playback unit 1 at a high speed (high speed). Record). The MD recording / playback unit 2 plays back the music data recorded on the MD, and outputs the played back music data to the DAC 3.
[0029]

[0031]
The display unit 5 displays predetermined marks, character strings, and the like, and indicates the operating status of the audio system to the user.
[0032]
The memory 6 includes a RAM (Random Access Memory) or the like, and stores the CD track information and the MD track information. Further, the memory 6 stores a correspondence table used for prohibiting high-speed dubbing for copyright protection or for canceling this prohibition. For example, as shown in FIG. 2, the correspondence table is configured by associating a reproduction track indicating music data to be dubbed at a high speed and a recording track number of an MD as a dubbing destination. The reproduction track indicates, for example, the type of CD on which music data to be dubbed at high speed is recorded, and the track number (TNO). The type of CD is indicated by the total time (DISC TOTAL TIME) of the CD and the number of tracks (MAX TNO). Also, when the same music data is dubbed at high speed a plurality of times on the same MD, as shown in FIG. 2, a plurality of recording track numbers are recorded in the order of high speed dubbing for one playback track. .
[0033]
The timer 7 counts the dubbing prohibition time (for example, 74 minutes) set to protect the copyright of the music data. Specifically, when the timer 7 is supplied with a high-speed dubbing start signal from the controller 8, the timer 7 starts counting the dubbing inhibition time. When the same music data is dubbed a plurality of times, the timer 7 is supplied with a high-speed dubbing start signal from the controller 8 a plurality of times, and repeatedly counts the dubbing prohibition time as many times as the high-speed dubbing start signal is supplied. Each time the timer 7 finishes counting the dubbing inhibition time, it outputs a count end signal indicating that the count has ended to the controller 8.
[0034]
The controller 8 is composed of a microcomputer composed of a CPU (Central Processing Unit) and a peripheral LSI (Large Scale Integration). The controller 8 uses the CD playback unit 1, MD recording / playback unit 2, operation unit 4, and various information and signals supplied from the timer 7 to use the CD playback unit 1, MD recording / playback unit 2, DAC 3, The operations of the display unit 5, the memory 6, and the timer 7 are controlled to perform high-speed dubbing of music data. Detailed operation of the controller 8 will be described later.
[0035]
Next, the operation of the recording / reproducing apparatus configured as described above will be described. In the following, the operation of the recording / reproducing apparatus is as follows: (1) When dubbing music data at high speed, (2) When counting of the dubbing prohibition time is completed, (3) When removing the MD from the recording / reproducing apparatus This will be explained separately.
[0036]
(1) When music data is dubbed at high speed
First, a user of the recording / reproducing apparatus sets a predetermined number of CDs on which music data to be subjected to high-speed dubbing is recorded in the CD reproducing unit 1 and sets an MD as a dubbing destination in the MD recording / reproducing unit 2.
The CD playback unit 1 acquires the total time and the number of tracks of the CD from the TOC information of each set CD, generates the CD track information, and outputs it to the controller 8.
[0037]
Further, the MD recording / reproducing unit 2 acquires the number of MD tracks from the set MD TOC information, generates the MD track information, and outputs the MD track information to the controller 8.
The controller 8 stores the CD track information supplied from the CD playback unit 1 and the MD track information supplied from the MD recording / playback unit 2 in the memory 6.
[0038]
Next, the user of the recording / playback apparatus operates the operation unit 4 to set the disc number and track number of the CD on which the high-speed dubbing target music data is recorded, the dubbing order, and the like.
The operation unit 4 outputs the disc number, track number, dubbing order, etc. set by the user to the controller 8 as a high-speed dubbing signal.
[0039]
In response to the high-speed dubbing signal supplied from the operation unit 4, the controller 8 starts the high-speed dubbing process shown in FIG.
First, the controller 8 determines whether or not the timer 7 has finished counting the dubbing prohibition time, that is, whether or not the dubbing prohibition time set in the previous high-speed dubbing has elapsed (step S101). .
[0040]
When it is determined that the dubbing prohibition time has elapsed (step S101; YES), the controller 8 controls the CD playback unit 1 and the MD recording / playback unit 2 and the music indicated by the high-speed dubbing signal supplied from the operation unit 4 Data is dubbed at high speed from CD to MD in the order indicated by the high speed dubbing signal. Further, the controller 8 creates the correspondence table from the high-speed dubbing signal supplied from the operation unit 4 and the CD track information and MD track information stored in the memory 6. Then, the controller 8 stores the created correspondence table in the memory 6 (step S102), and ends the high-speed dubbing process. Thus, when a predetermined dubbing prohibition time has elapsed since the previous high-speed dubbing, high-speed dubbing can be performed.
[0041]
When starting high-speed dubbing, the controller 8 outputs a high-speed dubbing start signal indicating the start of high-speed dubbing to the timer 7. Thereby, the timer 7 starts counting a predetermined dubbing prohibition time (for example, 74 minutes). At this time, the controller 8 may display a mark or a character string indicating that high-speed dubbing is being performed on the display unit 5.
[0042]
On the other hand, when it is determined that the dubbing prohibition time has not elapsed (step S101; NO), the controller 8 determines whether or not the memory 6 stores the correspondence table (step S103).
[0043]
When it is determined that it is not stored (step S103; NO), the controller 8 acquires the remaining time until high-speed dubbing is possible from the timer 7 and displays it on the display unit 5 (step S104). The process ends. Thus, when the predetermined dubbing prohibition time has not elapsed since the previous high-speed dubbing and the memory 6 does not store the correspondence table, high-speed dubbing cannot be performed.
[0044]
On the other hand, when it is determined that it is stored (step S103; YES), the controller 8 determines whether or not information indicating the music data indicated by the high-speed dubbing signal is recorded on the reproduction track of the correspondence table. Then, the controller 8 determines whether or not the music data indicated by the high-speed dubbing signal is recorded on the playback track (step S105).
[0045]
If it is determined that there is no such data (step S105; NO), the controller 8 displays the remaining time until the processing in step S104, that is, high-speed dubbing becomes possible, and ends the high-speed dubbing processing. Thus, the predetermined dubbing prohibition time has not elapsed since the previous high-speed dubbing, and the music data indicated by the high-speed dubbing signal matches the music data indicated by the information recorded on the playback track of the correspondence table. If nothing is present, high-speed dubbing cannot be performed.
[0046]
On the other hand, if it is determined that it exists (step S105; YES), the controller 8 controls the CD playback unit 1 and the MD recording / playback unit 2 to record the music data determined to be recorded on the playback track as a high-speed dubbing signal. High-speed dubbing from CD to MD according to the order shown. Further, the controller 8 uses the high-speed dubbing signal from the operation unit 4 and the CD track information and the MD track information in the memory 6 to add the recording track number of the dubbing destination MD to the correspondence table (step S106). ), The high-speed dubbing process is terminated.
[0047]
When starting high speed dubbing, the controller 8 outputs the high speed dubbing start signal to the timer 7. Thereby, the timer 7 repeatedly counts the predetermined dubbing prohibition time as many times as the high-speed dubbing start signal is supplied. At this time, the controller 8 may display a mark or a character string indicating that high-speed dubbing is being performed on the display unit 5.
[0048]
As described above, even if a predetermined dubbing prohibition time has not elapsed since high-speed dubbing has been performed, high-speed dubbing is performed as long as information indicating the music data to be dubbed at high speed is recorded on the playback track of the correspondence table. be able to. That is, even if a predetermined dubbing prohibition time has not elapsed since high-speed dubbing has been performed, high-speed dubbing can be performed as long as the music data is the same as the music data previously dubbed at high speed. However, since the music data recorded during the dubbing prohibition time is data subject to high-speed dubbing prohibition, the MD cannot be taken out from the recording / reproducing apparatus while the music data subject to high-speed dubbing prohibition is recorded. In other words, the music data subject to high-speed dubbing prohibition is excluded from the high-speed dubbing prohibition target when the dubbing prohibition time set by the previous high-speed dubbing has elapsed, and can be taken out while being recorded on the MD.
[0049]
(2) When the dubbing prohibition time has been counted
By the high-speed dubbing process, the timer 7 counts a predetermined dubbing prohibition time, and outputs a count end signal to the controller 8 every time the dubbing prohibition time is counted.
In response to the count end signal supplied from the timer 7, the controller 8 starts the correspondence table deletion process shown in FIG.
[0050]
First, the controller 8 determines whether or not the memory 6 stores the correspondence table (step S201).
If it is determined that it is not stored (step S201; NO), the controller 8 ends the correspondence table deletion process.
[0051]
If it is determined that it is stored (step S201; YES), the controller 8 deletes the information related to the music data recorded by the first high-speed dubbing from the information recorded in the correspondence table. In other words, the controller 8 deletes information related to music data that is not subject to high-speed dubbing prohibition from the correspondence table (step S202).
[0052]
For example, when high-speed dubbing is performed three times after the elapse of the dubbing prohibition time, music data that has been dubbed at high speed for the first time does not fall under the high-speed dubbing prohibition target. In addition, the music data that has been dubbed at high speed for the second time corresponds to a high-speed dubbing prohibition target unless the dubbing prohibition time set in the first high-speed dubbing has elapsed. The music data that has been dubbed at high speed for the third time corresponds to a high-speed dubbing prohibition object unless the dubbing prohibition time set in the second high-speed dubbing has elapsed. When the controller 8 finishes counting the dubbing prohibition time set in the first high-speed dubbing, the controller 8 deletes the music data that is not the target of high-speed dubbing, that is, information related to the music data that has been dubbed at the first time from the correspondence table. As a result, the music data that has been dubbed at the high speed for the second time is excluded from the high speed dubbing prohibition targets.
[0053]
This is the end of the correspondence table deletion process. When deleting the music data information, the controller 8 completely deletes the information related to the predetermined music data from the correspondence table, for example, by overwriting the predetermined data. At this time, the controller 8 may update the TOC information of the MD.
As described above, every time the dubbing prohibition time elapses, the information regarding the music data that is not the dubbing prohibition target is sequentially deleted from the correspondence table of the memory 6.
[0054]
(3) When removing the MD from the recording / reproducing apparatus
After the high-speed dubbing process is completed, when the user of the recording / reproducing apparatus operates the operation unit 4 in a predetermined procedure in order to take out the MD from the MD recording / reproducing unit 2, the operation unit 4 follows the predetermined operation of the user. The disk ejection signal is output to the controller 8.
[0055]
In response to the disc ejection signal supplied from the operation unit 4, the controller 8 starts the disc ejection process shown in FIG.
First, the controller 8 determines whether or not there is music data to be prohibited from high-speed dubbing in the music data recorded on the MD (step S301). Specifically, the controller 8 refers to the correspondence table in the memory 6 and determines whether or not there is one in which two or more recording track numbers are recorded for one reproduction track.
[0056]
As described above, every time the dubbing prohibition time elapses, information related to music data that is not a dubbing prohibition target is sequentially deleted from the correspondence table in the memory 6. Therefore, if two or more recording track numbers are recorded for one playback track, it can be determined that there is music data for which high-speed dubbing is prohibited.
[0057]
When it is determined that there is no music data subject to high-speed dubbing prohibition (step S301; NO), the controller 8 performs a process of step S305 described later. On the other hand, if it is determined that it exists (step S301; YES), the controller 8 controls the display unit 5 to display a message for confirming with the user that the disc is ejected (step S302). For example, if the MD is taken out as it is, the controller 8 displays a confirmation message indicating that there is music data to be deleted to protect the copyright. Further, the controller 8 acquires the time until the MD can be taken out without deleting the music data from the timer 7 and displays it.
[0058]
The user of the recording / reproducing apparatus operates the operation unit 4 in a predetermined procedure and selects execution or cancellation of the disc ejection. Then, the operation unit 4 outputs a confirmation signal indicating the selection result of the user to the controller 8.
The controller 8 determines whether or not a confirmation signal indicating execution of disc ejection is supplied from the operation unit 4 within a predetermined time (step S303).
[0059]
When it is determined that a confirmation signal indicating execution of disk ejection is not supplied, specifically, when a confirmation signal is not supplied from the operation unit 4 or when a confirmation signal indicating suspension of disk ejection is supplied (step S303). NO), the controller 8 ends the disc ejection process.
[0060]
On the other hand, if it is determined that a confirmation signal indicating execution of disc ejection has been supplied (step S303; YES), the controller 8 uses the correspondence table in the memory 6 to record the MD data on which high-speed dubbing prohibition is recorded. The recording track number is determined. Then, the controller 8 controls the MD recording / reproducing unit 2 to erase the music data recorded in the determined recording track number from the MD (step S304). At this time, the controller 8 controls the MD recording / reproducing unit 2 to completely erase the predetermined music data from the MD by overwriting the predetermined data, for example. At this time, the controller 8 may update the TOC information of the MD.
[0061]
Thereafter, the controller 8 deletes the correspondence table stored in the memory 6 (step S305). At this time, the controller 8 completely erases the correspondence table from the memory 6 by overwriting predetermined data, for example.
Subsequently, the controller 8 controls the MD recording / reproducing unit 2 to eject the MD (step S306), and ends the disc ejection process.
[0062]
By the high-speed dubbing process, even if a predetermined dubbing prohibition time has not elapsed, the same music data can be dubbed to the same MD a plurality of times. For this reason, the user of the recording / reproducing apparatus can input the setting of the next high-speed dubbing without waiting for the dubbing prohibition time to elapse, and can efficiently perform high-speed dubbing of music data. Further, as described above, since the MD cannot be taken out from the recording / reproducing apparatus while the music data for which high-speed dubbing is prohibited is recorded, the copyright of the music data can be protected.
[0063]
(Concrete example)
Next, the operation of the recording / reproducing apparatus described above will be described using a specific example.
1. Example 1
First, a case will be described in which three pieces of music data (music data A, B, and C) recorded on different CDs are dubbed to MD at high speed after the elapse of the dubbing prohibition time. It is assumed that no music data is recorded in the dubbing destination MD.
[0064]
A user of the recording / reproducing apparatus sets three CDs as dubbing sources in the CD reproducing unit 1 and sets an MD as a dubbing destination in the MD recording / reproducing unit 2.
The CD playback unit 1 acquires the total time and number of tracks of the CD from the TOC information of each set CD, generates CD track information shown in FIG. 6A, and outputs it to the controller 8.
[0065]
Further, the MD recording / reproducing unit 2 acquires the number of MD tracks from the set MD TOC information, generates the MD track information shown in FIG. 6B, and outputs it to the controller 8.
The controller 8 stores the CD track information supplied from the CD playback unit 1 and the MD track information supplied from the MD recording / playback unit 2 in the memory 6.
[0066]
Next, the user of the recording / playback apparatus operates the operation unit 4 to set the disc number and track number of the CD on which the high-speed dubbing target music data is recorded, the dubbing order, and the like. Specifically, the user firstly stores the music data A recorded on the track 3 of the disk 2, secondly the music data B recorded on the track 5 of the disk 3, and thirdly the disk 1. High-speed dubbing of the music data C recorded on the track 1 is set.
[0067]
The operation unit 4 outputs the disc number, track number, dubbing order, etc. set by the user to the controller 8 as a high-speed dubbing signal.
In response to the high-speed dubbing signal supplied from the operation unit 4, the controller 8 starts the high-speed dubbing process shown in FIG.
[0068]
First, the controller 8 determines whether or not the timer 7 has finished counting the dubbing prohibition time, that is, whether or not the dubbing prohibition time set in the previous high-speed dubbing has elapsed (step S101).
[0069]
In this case, the controller 8 determines that the time has passed (step S101; YES), controls the CD playback unit 1 and the MD recording / playback unit 2, and the music data indicated by the high-speed dubbing signal is in the order indicated by the high-speed dubbing signal. To perform high speed dubbing from CD to MD. Further, the controller 8 creates a correspondence table shown in FIG. 7A from the high-speed dubbing signal from the operation unit 4 and the CD track information and MD track information in the memory 6. Then, the controller 8 stores the created correspondence table in the memory 6 (step S102), and ends the high-speed dubbing process.
[0070]
When starting high-speed dubbing, the controller 8 outputs a high-speed dubbing start signal indicating the start of high-speed dubbing to the timer 7. Thereby, the timer 7 starts counting a predetermined dubbing prohibition time (for example, 74 minutes). At this time, the controller 8 may display a mark or a character string indicating that high-speed dubbing is being performed on the display unit 5.
As described above, when the dubbing prohibition time set in the previous high-speed dubbing has elapsed, high-speed dubbing of music data is performed according to the user's setting.
[0071]
2. Example 2
Next, before the dubbing prohibition time set in the specific example 1 elapses, three pieces of music data (music data A, B, D) recorded on the same CD as the CD shown in the specific example 1 are stored in the MD. A case of high-speed dubbing will be described.
[0072]
As described above, the user of the recording / reproducing apparatus firstly stores the music data A recorded on the track 3 of the disk 2 and the music data B recorded on the track 5 of the disk 3 second. Thirdly, the high speed dubbing of the music data D recorded on the track 1 of the disc 2 is set. Note that the music data A and B in which the order of dubbing is set to the first and second are the same as the music data A and B that have been dubbed at high speed in the specific example 1, and the music data D set to the third is This is different from the music data dubbed at high speed in the specific example 1.
[0073]
The operation unit 4 outputs the disc number, track number, dubbing order, etc. set by the user to the controller 8 as a high-speed dubbing signal.
In response to the high-speed dubbing signal supplied from the operation unit 4, the controller 8 starts the high-speed dubbing process shown in FIG.
[0074]
First, the controller 8 determines whether or not the timer 7 has finished counting the dubbing prohibition time, that is, whether or not the dubbing prohibition time set in the previous high-speed dubbing has elapsed (step S101).
In this case, the controller 8 determines that it has not elapsed (step S101; NO), and determines whether the memory 6 stores a correspondence table (step S103).
[0075]
In this case, the controller 8 determines that it is stored (step S103; YES), and determines whether information indicating the music data A, B, D is recorded on the reproduction track of the correspondence table. Then, the controller 8 determines whether or not the music data A, B, D is recorded on the reproduction track (step S105).
[0076]
As described above, since the music data A and B are the same as the music data A and B that have been dubbed at high speed in the specific example 1, the controller 8 determines that they exist (step S105; YES).
[0077]
Then, the controller 8 controls the CD playback unit 1 and the MD recording / playback unit 2 to perform high speed dubbing of the music data A and B determined to be recorded on the playback track of the correspondence table from CD to MD. Further, the controller 8 uses the high-speed dubbing signal from the operation unit 4 and the CD track information and MD track information in the memory 6 to add the recording track number of the MD that is the dubbing destination to the correspondence table (step S106). ). Specifically, as shown in FIG. 7B, recording track number 4 on which music data A is recorded and recording track number 5 on which music data B is recorded are added.
[0078]
When starting high speed dubbing, the controller 8 outputs the high speed dubbing start signal to the timer 7. Thereby, the timer 7 repeatedly counts the predetermined dubbing prohibition time as many times as the high-speed dubbing start signal is supplied. At this time, the controller 8 may display a mark or a character string indicating that high-speed dubbing is being performed on the display unit 5.
[0079]
As described above, even if a predetermined dubbing prohibition time has not elapsed since high-speed dubbing has been performed, high-speed dubbing is performed as long as information indicating the music data to be dubbed at high speed is recorded on the playback track of the correspondence table. be able to. That is, even if a predetermined dubbing prohibition time has not elapsed since high-speed dubbing has been performed, high-speed dubbing can be performed as long as the music data is the same as the music data previously dubbed at high speed. However, as shown in the specific example 3, as long as the dubbing prohibition time set in the specific example 1 does not elapse, the music data dubbed at high speed in the specific example 2, that is, the music data subject to high speed dubbing prohibition is recorded. The MD cannot be taken out from the recording / reproducing apparatus.
[0080]
3. Example 3
Next, a case where the MD set in the specific example 1 is taken out from the recording / reproducing apparatus before the dubbing prohibition time set in the specific example 1 elapses will be described.
[0081]
A user of the recording / reproducing apparatus operates the operation unit 4 in a predetermined procedure in order to take out the MD from the MD recording / reproducing unit 2, and the operation unit 4 outputs a disc ejection signal to the controller 8 according to the user's predetermined operation. To do.
In response to the disc ejection signal supplied from the operation unit 4, the controller 8 starts the disc ejection process shown in FIG.
[0082]
First, the controller 8 determines whether or not there is music data to be prohibited from high-speed dubbing in the music data recorded on the MD (step S301). Specifically, the controller 8 refers to the correspondence table in the memory 6 and determines whether or not there is one in which two or more recording track numbers are recorded for one reproduction track.
[0083]
As shown in FIG. 7B, there are two recording track numbers on which the music data A and B are recorded. For this reason, the controller 8 determines that it exists (step S301; YES), and controls the display unit 5 to display a confirmation message for confirming with the user that the disc is ejected (step S302).
[0084]
The user of the recording / reproducing apparatus operates the operation unit 4 according to a predetermined procedure, and selects execution or cancellation of the disc ejection. Then, the operation unit 4 outputs a confirmation signal indicating the selection result of the user to the controller 8.
[0085]
The controller 8 determines whether or not a confirmation signal indicating execution of disc ejection is supplied from the operation unit 4 within a predetermined time (step S303).
When the user selects to cancel the disk ejection or when the execution of the disk ejection is not confirmed, the controller 8 determines that the confirmation signal indicating the execution of the disk ejection is not supplied from the operation unit 4 (step S303). NO), the disc ejection process is terminated.
[0086]
On the other hand, when the user selects execution of disc ejection, the controller 8 determines that a confirmation signal indicating execution of disc ejection is supplied from the operation unit 4 (step S303; YES), and from the correspondence table of the memory 6, The recording track number of the MD in which the music data for which high speed dubbing is prohibited is recorded is determined. In this case, the controller 8 determines that the music data for which high-speed dubbing is prohibited is recorded on the recording track numbers 4 and 5.
[0087]
Then, the controller 8 controls the MD recording / reproducing unit 2 to erase the music data A and B recorded on the MD recording track numbers 4 and 5 from the MD (step S304). At this time, the controller 8 controls the MD recording / reproducing unit 2 to completely erase the predetermined music data from the MD by overwriting the predetermined data, for example. At this time, the controller 8 may update the TOC information of the MD.
[0088]
Thereafter, the controller 8 completely erases the correspondence table stored in the memory 6 by overwriting predetermined data, for example (step S305).
Subsequently, the controller 8 controls the MD recording / reproducing unit 2 to eject the MD (step S306), and ends the disc ejection process.
[0089]
As described above, since the MD cannot be taken out from the recording / reproducing apparatus while the music data to be prohibited from high-speed dubbing is recorded, the copyright of the music data can be protected.
[0090]
4). Example 4
Next, a case will be described in which the dubbing prohibition time set in Specific Example 1 has elapsed, and then the MD set in Specific Example 1 is taken out from the recording / reproducing apparatus.
[0091]
When the timer 7 finishes counting the dubbing prohibition time set in Specific Example 1, the timer 7 starts counting the dubbing prohibition time set in Specific Example 2.
In addition, when the timer 7 finishes counting the dubbing prohibition time set in the specific example 1, the timer 7 outputs a count end signal indicating that the counting is ended to the controller 8.
[0092]
In response to the count end signal supplied from the timer 7, the controller 8 starts the correspondence table deletion process shown in FIG.
First, the controller 8 determines whether or not the memory 6 stores a correspondence table (step S201).
[0093]
In this case, the controller 8 determines that it is stored (step S201; YES), and the music recorded by the first high-speed dubbing among the information recorded in the correspondence table of FIG. 7B. Delete information about data. In other words, the controller 8 deletes the information related to the music data that is not subject to the high-speed dubbing prohibition from the correspondence table in FIG. 7B (step S202). Specifically, as shown in FIG. 7C, the controller 8 deletes the information related to the music data dubbed at high speed in the specific example 1. When deleting the music data information, the controller 8 completely erases the information related to the predetermined music data from the correspondence table, for example, by overwriting the predetermined data. At this time, the controller 8 may update the TOC information of the MD.
This is the end of the correspondence table deletion process.
[0094]
Thereafter, the user of the recording / reproducing apparatus operates the operation unit 4 in a predetermined procedure in order to take out the MD from the MD recording / reproducing unit 2, and the operation unit 4 sends the disc ejection signal to the controller 8 according to the predetermined operation of the user. Output to.
In response to the disc ejection signal supplied from the operation unit 4, the controller 8 starts the disc ejection process shown in FIG.
[0095]
First, the controller 8 determines whether or not there is music data to be prohibited from high-speed dubbing in the music data recorded on the MD (step S301). Specifically, the controller 8 refers to the correspondence table in the memory 6 and determines whether or not there is one in which two or more recording track numbers are recorded for one reproduction track.
[0096]
As shown in FIG. 7C, there is no record in which two or more recording track numbers are recorded for one reproduction track. For this reason, the controller 8 determines that there is no music data subject to high-speed dubbing prohibition (step S301; NO), and deletes the correspondence table stored in the memory 6 (step S305). At this time, the controller 8 completely erases the correspondence table from the memory 6 by overwriting predetermined data, for example. At this time, the controller 8 may update the TOC information of the MD.
Subsequently, the controller 8 controls the MD recording / reproducing unit 2 to eject the MD (step S306), and ends the disc ejection process.
[0097]
As described above, even if the predetermined dubbing prohibition time has not elapsed, the same music data can be dubbed to the same MD at a high speed a plurality of times. Thus, the user of the recording / reproducing apparatus can input an instruction for the next high-speed dubbing without waiting for the dubbing prohibition time to elapse, and can efficiently perform high-speed dubbing of music data. Also, before the dubbing prohibition time elapses, the same music data cannot be dubbed multiple times to different MDs, and it is not possible to take out the MD from the recording / reproducing apparatus while recording the music data subject to high speed dubbing prohibition. Since this is not possible, the copyright of the music data can be protected.
[0098]
In the above embodiment, after high-speed dubbing of music data to MD, music data for which high-speed dubbing is prohibited is deleted when MD is ejected, but high-speed dubbing target music data is dubbed to memory 6 at high speed, Every time the dubbing prohibition time elapses, the music data excluded from the high-speed dubbing prohibition target may be sequentially recorded from the memory 6 to the MD. In this case, the controller 8 performs the following high-speed dubbing process, correspondence table deletion process, and disk ejection process.
[0099]
(High-speed dubbing process)
In response to the high-speed dubbing signal supplied from the operation unit 4, the controller 8 starts the high-speed dubbing process shown in FIG.
First, the controller 8 determines whether or not the timer 7 has finished counting the dubbing prohibition time, that is, whether or not the dubbing prohibition time set in the previous high-speed dubbing has elapsed (step S401). .
[0100]
If it is determined that the dubbing prohibition time has elapsed (step S401; YES), the controller 8 changes the music data indicated by the high speed dubbing signal supplied from the operation unit 4 from CD to MD in the order indicated by the high speed dubbing signal. High speed dubbing. Further, the controller 8 creates the correspondence table and stores it in the memory 6 (step S402), and ends the high-speed dubbing process.
[0101]
On the other hand, when it is determined that the dubbing prohibition time has not elapsed (step S401; NO), the controller 8 determines whether or not the memory 6 stores the correspondence table (step S403).
When it is determined that it is not stored (step S403; NO), the controller 8 acquires the remaining time until high-speed dubbing is possible from the timer 7 and displays it on the display unit 5 (step S404). The process ends.
[0102]
On the other hand, if it is determined that the data is stored (step S403; YES), the controller 8 determines whether or not the music data indicated by the high-speed dubbing signal is recorded on the playback track of the correspondence table. A determination is made (step S405). If it is determined that it does not exist (step S405; NO), the controller 8 performs the process of step S404 and ends the high-speed dubbing process.
[0103]
On the other hand, if it is determined that it exists (step S405; YES), the controller 8 performs high-speed dubbing of the music data determined to be recorded on the reproduction track from the CD to the memory 6 in the order indicated by the high-speed dubbing signal. Further, the controller 8 adds the MD recording track number, which is the final dubbing destination, to the correspondence table (step S406), and ends the high-speed dubbing process.
[0104]
(Corresponding table deletion processing)
In response to the count end signal supplied from the timer 7, the controller 8 starts the correspondence table deletion process shown in FIG.
[0105]
First, the controller 8 determines whether or not the memory 6 stores the correspondence table (step S501).
If it is determined that it is not stored (step S501; NO), the controller 8 ends the correspondence table deletion process.
[0106]
If it is determined that it is stored (step S501; YES), the controller 8 completely deletes the information related to the music data that is not subject to the high speed dubbing prohibition from the correspondence table by overwriting predetermined data, for example (step S502). . At this time, the controller 8 may update the TOC information of the MD.
Then, the controller 8 determines the music data newly excluded from the high-speed dubbing prohibition target using the correspondence table, records the determined music data from the memory 6 to the MD (step S503), and performs correspondence table deletion processing. finish.
[0107]
(Disc ejection process)
The controller 8 starts the disk ejection process shown in FIG. 10 in response to the disk ejection signal supplied from the operation unit 4.
First, the controller 8 determines whether or not there is music data for which high-speed dubbing is prohibited in the music data recorded in the memory 6 (step S601). Specifically, the controller 8 refers to the correspondence table in the memory 6 and determines whether or not there is one in which two or more recording track numbers are recorded for one reproduction track.
[0108]
When it is determined that there is no music data subject to high-speed dubbing prohibition (step S601; NO), the controller 8 performs a process of step S605 described later. On the other hand, if it is determined that it exists (step S601; YES), the controller 8 controls the display unit 5 to display a message or the like for confirming with the user that the disc is ejected (step S602). For example, if the MD is taken out as it is, the controller 8 displays a confirmation message indicating that there is music data that is not recorded in order to protect the copyright. Further, the controller 8 acquires the time until the MD in which the predetermined music data is recorded can be taken out from the timer 7 and displays it.
[0109]
The user of the recording / reproducing apparatus operates the operation unit 4 in a predetermined procedure and selects execution or cancellation of the disc ejection. Then, the operation unit 4 outputs a confirmation signal indicating the selection result of the user to the controller 8.
The controller 8 determines whether or not a confirmation signal indicating execution of the disc ejection is supplied from the operation unit 4 within a predetermined time (step S603).
[0110]
When it is determined that the confirmation signal indicating the execution of the disk ejection is not supplied (step S603; NO), the controller 8 ends the disk ejection process.
On the other hand, if it is determined that a confirmation signal indicating execution of disc ejection has been supplied (step S603; YES), the controller 8 completely completes all music data that has been dubbed at high speed in the memory 6 by overwriting predetermined data, for example. Erasing is performed (step S604).
[0111]
Thereafter, the controller 8 completely erases the correspondence table stored in the memory 6 by overwriting predetermined data, for example (step S605). At this time, the controller 8 may update the TOC information of the MD.
Subsequently, the controller 8 controls the MD recording / reproducing unit 2 to eject the MD (step S606), and ends the disc ejection process.
[0112]
Even in the above manner, the same music data can be dubbed to the same MD a plurality of times at high speed without waiting for the dubbing prohibition time to elapse as in the above embodiment. That is, music data can be efficiently dubbed at high speed. In addition, since the music data for which high-speed dubbing is prohibited is not recorded on the MD, the copyright of the music data can be protected.
[0113]
The information indicating the music data recorded on the reproduction track of the correspondence table may be anything as long as the music data can be specified. For example, ISRC (International Standard Recording Code), which is information unique to the music indicated by the music data, may be used.
[0114]
The recording / reproducing apparatus can be applied not only to high-speed dubbing of music data from CD to MD, but also to general high-speed dubbing of programs and data. For example, the present invention can be applied to a case where image data, a program, or the like is dubbed at high speed onto a recording medium such as a CD-RAM or a DVD-RAM.
[0115]
