Abstract

PROBLEM TO BE SOLVED: To protect copyright and also to efficiently record data. SOLUTION: A memory 4 stores music data being a high-speed dubbing prohibition object and a music management table which indicates the remaining time of the high-speed dubbing prohibition time. When music data are dubbed at a high speed, a controller 8 judges whether music data to be set is excluded from the high-speed dubbing prohibition object or not when high-speed dubbing is started in the case of setting music data to be dubbed at high speed. A display part 6 displays that music data to be set is the high-speed dubbing prohibition object when the controller 8 judges that data is not excluded from the prohibition object. When data are judged to be excluded from the prohibition object, the controller 8 sets music data to be set as a high-speed dubbing object. Then, the controller 8 controls a CD reproducing part 1 and an MD recording and reproducing part 2 to perform the high-speed dubbing of music data being the high-speed dubbing object from a CD to an MD.

A dubbing target list indicating high-speed dubbed music data and a music management table indicating high-speed dubbed music data are stored. As shown in FIG. 2A, for example, the dubbing target list is configured such that the order of high-speed dubbing (dubbing order) is associated with a playback track indicating music data to be subjected to high-speed dubbing. For example, as shown in FIG. 2B, the music management table is set for each of high-speed dubbing order (dubbing order), a playback track indicating music data that has been subjected to high-speed dubbing, and music data to protect copyright. The remaining times of the dubbing prohibition time (for example, 74 minutes) are associated with each other. The playback track is, for example, a total playback time (DI) indicating the type of CD on which the music data is recorded.
SC TOTAL TIME), the number of tracks (MAX TNO), and the track number (TNO) indicating the position of the music data being recorded. The remaining time of the dubbing inhibition time is updated by the controller 8 every predetermined time (for example, one minute).

The operation unit 5 includes a plurality of operation buttons and the like.
Various signals and the like are output to the controller 8 according to a predetermined operation by a user of the recording / reproducing apparatus. For example, the operation unit 5

The display unit 6 displays a predetermined mark, a character string, and the like, and indicates to the user the operating status of the recording / reproducing apparatus. The timer 7 measures time under the control of the controller 8. Then, the timer 7 outputs an elapse signal indicating that the predetermined time has elapsed to the controller 8 every predetermined time (for example, one minute). Thereby, the above-mentioned dubbing inhibition time set for each music data is counted, and the remaining time of the dubbing inhibition time recorded in the music management table is updated.

The controller 8 has a CPU (Central Proc).
essing Unit) and peripheral LSI (Large Scale Integrat)
ion) and the like. The controller 8 creates the dubbing target list, performs high-speed dubbing of music data, and creates the music management table. In addition, the controller 8
In response to the elapsed signal supplied from the timer 7, the remaining time of the dubbing inhibition time recorded in the music management table is updated. Then, the controller 8 completely deletes information on the music data for which the remaining time has become zero from the music management table by overwriting, for example, predetermined data. Due to this deletion, the dubbing order of each music data recorded in the music management table is automatically advanced one by one. The detailed operation of the controller 8 will be described later.

Next, the operation of the recording / reproducing apparatus configured as described above will be described. (1) When Setting Music Data to be Dubbed at High Speed First, a user of the recording / reproducing apparatus sets a predetermined number of CDs recording music data to be set for high-speed dubbing in the CD reproducing unit 1, MD that is the destination of the dubbing
Set in the recording / reproducing unit 2.

The CD reproducing unit 1 is provided with the T
From the OC information, the total playback time of the CD, the number of tracks,
Then, it acquires the individual reproduction time and the like, generates the CD track information, and outputs it to the controller 8. The MD recording / reproducing unit 2 acquires the number of MD tracks and the like from the set TOC information of the MD, generates the MD track information, and outputs it to the controller 8.

The controller 8 causes the memory 4 to store the CD track information supplied from the CD reproducing section 1 and the MD track information supplied from the MD recording / reproducing section 2.
Next, the user of the recording / reproducing apparatus presses a predetermined operation button provided in the operation unit 5 to set music data to be dubbed at high speed. Thereby, the operation unit 5 outputs a program start signal for instructing the start of the program setting process to the controller 8.

The controller 8 starts the program setting process shown in FIG. 3 in response to the program start signal from the operation unit 5. First, the controller 8 clears the total program time stored in the memory 4. Specifically, the controller 8 sets the total program time of the memory 4 to zero (Step S101).

The user of the recording / reproducing apparatus operates the operation unit 5 according to a predetermined procedure, and selects one piece of music data to be set according to the setting order. Specifically, the user operates the operation unit 5 in a predetermined procedure, and determines the disc number of the CD on which the music data to be set is recorded, and the order of the music data to be set. Select the track number indicating. Thereby, the operation unit 5 outputs the disk number and the track number of the CD selected by the user to the controller 8.

The controller 8 specifies the music data to be set from the disk number and track number from the operation unit 5 and the CD track information in the memory 4, and the information indicating the specified music data is the music management data in the memory 4. It is determined whether or not it is recorded in the table (step S102). Thereby, the controller 8 determines whether or not the music data to be set is a high-speed dubbing prohibition target.

When it is determined that the information is not recorded (step S102; NO), the controller 8 performs the processing of step S106 described later. On the other hand, if it is determined that the music data is recorded (step S102; YES), the controller 8 determines whether or not the music data to be set is also a high-speed dubbing prohibition target even when the high-speed dubbing is started (step S103). Specifically, the controller 8
Determines whether the music data to be set is a high-speed dubbing prohibition target even when the high-speed dubbing is started, based on the total program time recorded in the memory 4 in step S106 described later.

For example, when two pieces of music data have already been set as high-speed dubbing targets, the sum of the individual reproduction times of these two pieces of music data is recorded in the memory 4 as the total program time. The controller 8 obtains the total program time from the memory 4 and obtains a dubbing time required for high-speed dubbing of two pieces of music data already set as high-speed dubbing targets. Specifically, the controller 8 calculates, for example, (total program time) / (speed magnification of high-speed dubbing) to obtain a dubbing time. Further, the controller 8 acquires the remaining time of the dubbing inhibition time set for the music data to be set from the music management table. And the controller 8
Determines whether the obtained remaining time is shorter than the dubbing time.

The above dubbing time is shorter than the time until the high-speed dubbing of the music data to be set is actually started. For this reason, if the remaining time of the dubbing prohibition time is shorter than the dubbing time, it is possible to determine that the music data to be set is excluded from the high-speed dubbing prohibition target at the start of the high-speed dubbing.

When it is determined that the remaining time is longer than the dubbing time, that is, when it is determined that high-speed dubbing is to be prohibited even at the start of high-speed dubbing (step S103; Y).
ES), the controller 8 controls the display unit 6 to display a warning message indicating that the music data to be set is a high-speed dubbing prohibition target and may not be high-speed dubbing (step S104). Thereby, the controller 8 confirms with the user of the recording / reproducing apparatus whether or not the setting target music data is set as the high speed dubbing target music data. The controller 8 calculates the remaining time of the high-speed dubbing prohibition time set in the music data to be set,
It may be displayed together with the warning message.

When the music data to be set is not set as the music data to be dubbed, the user of the recording / reproducing apparatus operates the operation unit 5 to cancel the setting. Thereby, the operation unit 5 outputs a cancellation signal for instructing cancellation of the setting to the controller 8.

The controller 8 determines whether or not the cancellation signal is supplied from the operation unit 5 within a predetermined time (step S105). When it is determined that the cancellation signal is not supplied (step S105; NO), the controller 8
Determines that the music data to be set is set as the music data to be dubbed, and performs the processing of step S106 described later. On the other hand, when it is determined that the cancellation signal has been supplied (step S105; YES), the controller 8
The processing of step S107 described below is performed.

In the process of step S103, when it is determined that the remaining time is shorter than the dubbing time, that is, when it is determined that high-speed dubbing is not to be prohibited at the start of high-speed dubbing (step S103; NO), the controller 8
Sets music data to be set as music data to be dubbed. Specifically, the controller 8 records information indicating the music data that has been newly dubbed in the dubbing target list in the memory 4. Further, the controller 8 acquires the individual reproduction time of the music data to be newly dubbed from the CD track information in the memory 4 and adds it to the total program time (step S106).

Thereafter, the controller 8 supplies a program end signal instructing the end of the program setting process from the operation unit 5 or a disk number and a track number indicating the music data to be set next. Is determined (step S107). When it is determined that the disk number and the track number have been supplied (step S107;
No.), the controller 8 returns to step S102. On the other hand, if it is determined that the program end signal has been supplied (step S107; end), the controller 8
Ends the program setting process.

As described above, the music data to be dubbed at high speed and the dubbing order are programmed. That is, a dubbing target list indicating the music data to be dubbed at high speed and the dubbing order is created. In addition, as described above, when there is a possibility that high-speed dubbing is prohibited even when the high-speed dubbing is started, the user of the recording / reproducing apparatus is notified of the possibility that high-speed dubbing will not be performed. This allows the user of the recording / reproducing apparatus to know the existence of music data that may not be subjected to high-speed dubbing before actually starting high-speed diving.

(2) When High-Speed Dubbing of Programmed Music Data After the above-mentioned program setting process is completed, the user of the recording / reproducing apparatus performs a predetermined operation provided in the operation unit 5 to perform high-speed dubbing of the music data. Press the button. As a result, the operation unit 5 outputs a high-speed dubbing signal for instructing the start of the high-speed dubbing process to the controller 8.

The controller 8 starts the high-speed dubbing process shown in FIG. 4 in response to the high-speed dubbing signal supplied from the operation unit 5. First, the controller 8 acquires the dubbing target list stored in the memory 4 (Step S201).

The controller 8 determines whether or not one of the music data recorded in the dubbing target list, for example, the music data having the first dubbing order, is recorded in the music management table of the memory 4. It is determined (step S202). Thereby, the controller 8 determines whether or not the music data to be dubbed is a high-speed dubbing prohibition target. If it is determined that the information is recorded (step S202; YES), the controller 8 performs the process of step S204 described later.

On the other hand, if it is determined that no data has been recorded (step S202; NO), the controller 8
The reproducing unit 1 and the MD recording / reproducing unit 2 are controlled to perform high-speed dubbing of music data determined not to be recorded from the CD to the MD (step S203). At this time, the controller 8
Records information indicating the music data to be dubbed at high speed (total reproduction time, number of tracks, and track number) in the music management table of the memory 4. Also, the controller 8
Sets the dubbing prohibition time for the music data to be dubbed at high speed by recording the dubbing prohibition time (for example, 74 minutes) in the remaining time of the music management table. If the timer 7 is not operating at the start of high-speed dubbing, the controller 8 operates the timer 7 to count time.

Thereafter, the controller 8 refers to the dubbing target list in the memory 4 and determines whether or not there is music data to be dubbed next (step S20).
4). When it is determined that there is (Step S204; Y
ES), the controller 8 returns to step S202, and performs the above processing on the music data whose dubbing order is next. On the other hand, when it is determined that there is not (step S2
04; NO), the controller 8 ends the high-speed dubbing process.

As described above, when the predetermined music data is C
High-speed dubbing is performed sequentially from D to MD. When setting high-speed dubbing music data, the user of the recording / reproducing apparatus is notified of a high-speed dubbing prohibition target music data at the start of high-speed dubbing by a warning message or the like. As a result, the user of the recording / reproducing apparatus can know in advance the existence of music data that cannot be dubbed at high speed, and can take measures such as delaying the start of high-speed dubbing. Therefore, it is not necessary to redo the setting of the music data to be dubbed at a high speed, and the predetermined music data can be efficiently dubbed at a high speed.

(Specific Example) Next, the operation of the recording / reproducing apparatus will be described with a specific example. 1. Specific Example 1 First, a case where a user of a recording / reproducing apparatus sets music data to be dubbed at a high speed and the order thereof is described.
It is assumed that high-speed dubbing is performed at twice the normal speed.

The user of the recording / reproducing apparatus sets to perform high-speed dubbing of three pieces of music data recorded on different CDs. Specifically, first, disk 2
High-speed dubbing of the music data recorded on track 1 of the disc, the music data recorded on track 3 of the disc 3 second, and the music data recorded on track 1 of the disc 3 second. Set. In addition,
It is assumed that the information indicating the second music data is recorded in the music management table of the memory 4.

The user of the recording / reproducing apparatus sets three CDs recording the music data to be set in the CD reproducing section 1 and sets the dubbing destination MD in the MD recording / reproducing section 2. It is assumed that no music data is recorded on the MD that is the dubbing destination.

The CD reproducing section 1 sets the T of each set CD.
From the OC information, the total playback time of the CD, the number of tracks,
Then, an individual reproduction time and the like are acquired, and for example, CD track information shown in FIG. The MD recording / reproducing unit 2 acquires the number of MD tracks and the like from the set TOC information of the MD.
The MD track information shown in (b) is generated and output to the controller 8.

The controller 8 causes the memory 4 to store the CD track information supplied from the CD reproducing section 1 and the MD track information supplied from the MD recording / reproducing section 2.
Next, the user of the recording / reproducing apparatus presses a predetermined operation button provided in the operation unit 5 to set music data to be dubbed at high speed. Thereby, the operation unit 5 outputs a program start signal to the controller 8.

The controller 8 starts the program setting process shown in FIG. 3 in response to the program start signal from the operation unit 5. First, the controller 8 clears the total program time stored in the memory 4 (Step S101).

The user of the recording / reproducing apparatus operates the operation unit 5 according to a predetermined procedure. First, the disc number (disc 2) and track number of the CD on which the music data to be set first is recorded. Select (Track 1). The operation unit 5 outputs the disk number (disk 2) and the track number (track 1) of the CD selected by the user to the controller 8.

The controller 8 specifies music data to be set from the disc number and track number of the CD from the operation unit 5 and the CD track information in the memory 4, and information indicating the specified music data is stored in the memory 4. It is determined whether or not it is recorded in the music management table (step S10)
2). Note that the memory 4 stores a music management table shown in FIG. In this case, the controller 8 determines that the information indicating the music data recorded on the track 1 of the disk 2 is not recorded in the music management table (step S102; NO).

Then, the controller 8 sets the music data recorded on the track 1 of the disk 2 as music data to be dubbed. Specifically, as shown in FIG. 6B, the controller 8 sets the music data recorded on the track 1 of the disk 2 as the music data having the first dubbing order, and sets the information indicating the music data. Is recorded in the dubbing target list of the memory 4. Further, the controller 8 acquires the individual reproduction time (12 minutes) of the music data recorded on the track 1 of the disk 2 from the CD track information of the memory 4 and adds it to the total program time (step S106).

Thereafter, the controller 8 supplies a program end signal for instructing the end of the program setting process from the operation unit 5 or a disk number and a track number indicating the music data to be set next. Is determined (step S107).

In this case, the user of the recording / reproducing apparatus operates the operation unit 5 to operate the operation unit 5 to record the disk number (disc 1) and track number (track 3) of the CD in which the music data to be set second is recorded. Select The operation unit 5 outputs the disk number (disk 1) and the track number (track 3) of the CD selected by the user to the controller 8.

The controller 8 determines that the disk number and the track number have been supplied (step S107; number), returns to step S102, and performs the above processing. However, information indicating the music data recorded on the track 3 of the disk 1 is recorded in a music management table as shown in FIG. Therefore, the controller 8 stores the information indicating the music data recorded on the track 3 of the disk 1 in the memory 4 in the process of step S102.
(Step S102; YES).

Subsequently, the controller 8 determines whether or not the music data recorded on the track 3 of the disk 1 is also subject to high-speed dubbing prohibition at the start of the high-speed dubbing (step S103). Specifically, the controller 8 obtains the total program time from the memory 4 and obtains the dubbing time. In this case, since the total program time is 12 minutes, the dubbing time is 12/2 = 6 minutes. Further, the controller 8 controls the track 3 of the disk 1
The remaining time of the dubbing inhibition time set for the music data recorded in the music data is acquired from the music management table. As shown in FIG. 6A, the remaining time is 74 minutes. Then, the controller 8 determines whether or not the obtained remaining time is shorter than the dubbing time.

In this case, the controller 8 determines that the remaining time is longer than the dubbing time, that is, that the high-speed dubbing is prohibited even when the high-speed dubbing is started (step S).
103; YES). Then, the controller 8 controls the display unit 6 to display a warning message indicating that the music data to be set is a high-speed dubbing prohibition target and may not be high-speed dubbing (step S104). Thereby, the controller 8 confirms with the user of the recording / reproducing apparatus whether or not the setting target music data is set as the high speed dubbing target music data. The controller 8
May display the remaining time (74 minutes) of the high-speed dubbing prohibition time set in the music data to be set, together with the warning message.

Thereafter, the controller 8 determines whether or not a cancellation signal instructing cancellation of the setting is supplied from the operation unit 5 within a predetermined time (step S105). If the controller 8 determines that the cancellation signal is not supplied within a predetermined time (step S105; NO), the controller 8 determines that the music data recorded on the track 3 of the disk 1 is set as the music data to be dubbed.

Then, as shown in FIG. 6B, the controller 8 sets the music data recorded on the track 3 of the disk 1 as the music data having the second dubbing order, and sets the information indicating this music data. Is recorded in the dubbing target list of the memory 4. Further, the controller 8 acquires the individual reproduction time (10 minutes) of the music data recorded on the track 3 of the disk 1 from the CD track information of the memory 4 and adds it to the total program time (step S10).
6).

Thereafter, the controller 8 determines whether a program end signal indicating the end of the program setting process is supplied from the operation unit 5 or a disk number and a track number indicating the music data to be set next are supplied. It is determined (step S107). In this case, the user of the recording / reproducing apparatus operates the operation unit 5 to select the disk number (disk 3) and the track number (track 1) of the CD on which the music data to be set as the third setting is recorded. . The operation unit 5 outputs the disk number (disk 3) and the track number (track 1) of the CD selected by the user to the controller 8.

The controller 8 determines that the disk number and the track number have been supplied (step S107; number), returns to step S102, and performs the above processing. However, information indicating the music data recorded on track 1 of the disk 3 is not recorded in the music management table as shown in FIG. For this reason, the controller 8 determines in the process of step S102 that the information indicating the song data recorded on the track 1 of the disk 3 is not recorded in the song management table of the memory 4 (step S102; NO).

In the same manner as above, the controller 8 sets the music data recorded on the track 1 of the disk 3 as the music data having the third dubbing order, as shown in FIG. Information indicating the music data is recorded in a dubbing target list in the memory 4. Further, the controller 8 acquires the individual reproduction time (8 minutes) of the music data recorded on the track 1 of the disk 3 from the CD track information in the memory 4 and adds it to the total program time (step S106).

Thereafter, the controller 8 determines whether a program end signal indicating the end of the program setting process is supplied from the operation unit 5 or a disk number and a track number indicating the music data to be set next are supplied. It is determined (step S107).

In this case, since there are three pieces of music data to be set, the user of the recording / reproducing apparatus presses a predetermined operation button provided in the operation unit 5 to end the program setting processing. Thereby, the operation unit 5 outputs a program end signal to the controller 8. Thereby, the controller 8 determines that the program end signal has been supplied (step S107; end), and ends the program setting process.

As described above, the music data to be subjected to high-speed dubbing and the dubbing order are set, and the music data to be subjected to high-speed dubbing and the dubbing target list indicating the dubbing order are created. In addition, as described above, when the music data to be set may be subject to high-speed dubbing prohibition even at the start of high-speed dubbing, the user of the recording / reproducing apparatus is notified that high-speed dubbing may not be performed. You. This allows the user of the recording / reproducing apparatus to know the existence of music data that may not be subjected to high-speed dubbing before actually starting high-speed dubbing.

2. Specific Example 2 Next, a case in which three pieces of music data set in Specific Example 1 are dubbed at high speed will be described. It is assumed that the music data in the second dubbing order is also subject to high-speed dubbing prohibition even at the start of the high-speed dubbing. After the program setting process is completed, the user of the recording / reproducing apparatus presses a predetermined operation button provided in the operation unit 5 in order to perform high-speed dubbing of music data. Thereby, the operation unit 5 outputs a high-speed dubbing signal to the controller 8.

The controller 8 starts the high-speed dubbing process shown in FIG. 4 in response to the high-speed dubbing signal supplied from the operation unit 5. First, the controller 8 is configured as shown in FIG.
The dubbing target list shown in (b) is acquired from the memory 4 (step S201).

Then, the controller 8 determines whether or not the information indicating the music data whose dubbing order is the first indicated in the dubbing target list is recorded in the music management table of the memory 4 (step S202).

In this case, as shown in FIGS. 6A and 6B, the music data whose dubbing order is the first in the dubbing target list is not recorded in the music management table. Therefore, the controller 8 determines that the music data has not been recorded (step S202; NO), controls the CD reproduction unit 1 and the MD recording / reproduction unit 2, and stores the music data whose dubbing order indicated by the dubbing target list is the first. High-speed dubbing from a CD to an MD is performed (step S203).

At this time, the controller 8 records information indicating the music data to be dubbed at high speed (total reproduction time, number of tracks, and track number) in the music management table as shown in FIG. 7A. Also, the controller 8
Sets the dubbing prohibition time for the music data to be dubbed at high speed by recording the dubbing prohibition time (for example, 74 minutes) in the remaining time of the music management table. If the timer 7 is not operating at the start of high-speed dubbing, the controller 8 operates the timer 7 to count time.

Thereafter, the controller 8 refers to the dubbing target list in the memory 4 and determines whether or not there is music data to be dubbed next (step S20).
4). In this case, the controller 8 determines that the music data exists (step S204; YES), returns to step S202, and stores the information indicating the second music data in the dubbing order in the dubbing target list in FIG. It is determined whether or not it is recorded in the music management table.

In this case, as shown in FIGS. 6A and 6B, the music data having the second dubbing order shown in the dubbing target list is recorded in the music management table. For this reason, the controller 8 determines that the music data is recorded (step S202; YES), and determines whether or not the music data to be dubbed next exists in the dubbing target list of the memory 4 (step S204). .

In this case, the controller 8 determines that it exists (step S204; YES), and proceeds to step S20.
2 and the above processing is performed on the music data whose dubbing order is the third in the dubbing target list in FIG. 6B.

As shown in FIGS. 6A and 6B, the information indicating the third music data in the dubbing order shown in the dubbing target list is not recorded in the music management table. For this reason, the controller 8 controls the CD reproducing unit 1 and the MD recording / reproducing unit 2 to perform high-speed dubbing of the music data having the third dubbing order indicated by the dubbing target list from the CD to the MD (step S203).

At this time, the controller 8 records information indicating the music data to be dubbed at a high speed (total reproduction time, number of tracks, and track number) in the music management table as shown in FIG. 7B. Also, the controller 8
Sets the dubbing prohibition time for the music data to be dubbed at high speed by recording the dubbing prohibition time (for example, 74 minutes) in the remaining time of the music management table.

Thereafter, the controller 8 refers to the dubbing target list in the memory 4 and determines whether or not there is music data to be dubbed next (step S20).
4). In this case, the controller 8 determines that it does not exist (step S204; NO), and ends the high-speed dubbing process.

As described above, the predetermined music data is
High-speed dubbing is performed sequentially from D to MD. Also, music data that is subject to high-speed dubbing prohibition at the start of high-speed dubbing is not subjected to high-speed dubbing, so that the copyright of the music data can be protected. In addition, when music data to be dubbed at high speed is set, the user of the recording / reproducing apparatus is notified by a message or the like of music data that may be subject to high-speed dubbing prohibition at the start of high-speed dubbing. As a result, the user of the recording / reproducing apparatus can know in advance the existence of music data that cannot be dubbed at high speed, and can take measures such as delaying the start of high-speed dubbing. Therefore, it is not necessary to redo the setting of the music data to be dubbed at a high speed, and the predetermined music data can be efficiently dubbed at a high speed.

If the controller 8 determines in step S103 of the program setting process that the music data to be set is a high-speed dubbing prohibition target even when the high-speed dubbing is started, the controller 8 does not confirm the music data without confirming to the user. The data need not be set as a high-speed dubbing target. Specifically, the controller 8 does not have to perform the process of step S105 of the program setting process.
Note that the warning message may be displayed only to notify the user that the music data to be set is a high-speed dubbing prohibition target.

The controller 8 may display a warning message or the like displayed in step S104 of the program setting process when it is determined in step S102 that the message is recorded in the music management table.

If the controller 8 determines in step S102 of the program setting process that the music data is recorded in the music management table, the controller 8 does not set the music data to be set as a high-speed dubbing target, and performs the processing of step S107. You may. Specifically, when the controller 8 determines in step S102 that the music is recorded in the music management table, the controller 8 performs steps S103, S104, and 105.
The processing of step S107 may be performed without performing the processing of. However, when the controller 8 determines in step S102 that the music data is recorded in the music management table, the controller 8 displays the above warning message or the like and notifies the user that the setting target music data is a high-speed dubbing prohibition target. You may.

The method of presenting to the user that the music data to be set is the object of prohibiting high-speed dubbing is not limited to the method of displaying the warning message. For example,
The fact that the music data to be set is a target for which high-speed dubbing is prohibited may be presented to the user by voice or a warning lamp.

The information indicating the type of music data recorded in the reproduction track of the music management table may be any information as long as the music data can be specified. For example, ISRC (Internat
ional Standard Recording Code) may be used.

Further, the recording / reproducing apparatus can read from a CD to an MD.
The present invention can be applied not only to high-speed dubbing of music data to a computer, 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, programs, and the like are dubbed at high speed on a recording medium such as a CD-RAM or a DVD-RAM.

The device of the present invention does not need to use a dedicated device, and can be realized by an ordinary computer. For example, a program and data for causing a computer to execute each of the above-described processes are recorded on a recording medium (floppy (registered trademark) disk, CD-ROM, or the like), distributed, installed, and executed on an OS.
