Abstract

PROBLEM TO BE SOLVED: To efficiently record data. SOLUTION: A control part 7 controls a CD reproduction part 1 and an MD recording and reproduction part 2 to record specific data, recorded on a CD, on an MD at a normal or high speed. The control part 7 decides whether or not the MD recording and reproduction part 2 is in the inhibition state wherein the data can not be recorded at the high speed and obtains the remaining time up to the cancel of the inhibition state when deciding that the MD recording and reproduction part 2 is in the inhibition state. Then the control part 7 compares the time needed to record the specific data at the normal speed with the time obtained by adding the time needed to record the specific data at the high speed to the remaining time to decide a recording speed which requires a shorter time. The control part 7 records the specific data at the decided recording speed thereafter. Here, the control part 7 records the specific data the remaining time later when deciding that the recording speed which requires the shorter time is the high speed.

The control unit 7 controls the operations of the CD reproducing unit 1, the MD recording / reproducing unit 2, the memory 4, the timer 5, and the display unit 6 according to various signals supplied from the input unit 3 and the like. Dubbing the music data on the MD. The detailed operation of the control unit 7 will be described later.

Next, the operation of the recording / reproducing apparatus configured as described above will be described. First, a user of the recording / reproducing apparatus sets a predetermined number of CDs on which music data to be dubbed are recorded in the CD reproducing unit 1 and sets an MD to which dubbing is performed in the MD recording / reproducing unit 2.

The CD reproducing unit 1 reproduces the TOC information recorded on each set CD, generates the CD-TOC information, and outputs it to the control unit 7. MD recording and playback unit 2
Reproduces the TOC information recorded on the set MD, generates the MD-TOC information, and outputs the MD-TOC information to the control unit 7.

The control section 7 causes the memory 4 to store the CD-TOC information supplied from the CD reproduction section 1 and the MD-TOC information supplied from the MD recording / reproduction section 2. After setting the CD and MD, the user of the recording / reproducing apparatus operates the input button or the like of the input unit 3 to select the dubbing mode.

The user operates the input button of the input unit 3 to input the disc number and track number of the CD on which the music data to be dubbed is recorded in the order of dubbing.

The input section 3 outputs to the control section 7 a dubbing signal indicating a dubbing mode, a disc number, a track number and the like selected or inputted by the user. The control unit 7
In response to the dubbing signal supplied from the input unit 3, FIG.
Is started.

First, the control unit 7 determines whether the dubbing mode indicated by the dubbing signal is a normal mode, a high-speed mode,
It is determined which mode is the I mode (step S10).
1). When it is determined that the mode is the normal mode (step S1
01; normal), the control unit 7 controls the CD reproducing unit 1 and the MD recording / reproducing unit 2 to normally dub the music data recorded on the disk number and the track number indicated by the dubbing signal to the MD (step S102). Then, the dubbing process ends.

If it is determined that the mode is the high-speed mode (step S101; high speed), the control section 7 performs a high-speed dubbing process described later (step S103), and ends the dubbing process. If it is determined that the mode is the AI mode (step S
101; AI), the control unit 7 performs an AI dubbing process described later (step S104), and ends the dubbing process.

FIG. 3 is a flowchart showing the high-speed dubbing process performed by the control unit 7. First, the control unit 7
Determines whether the timer 5 is counting the high-speed recording inhibition time. Thereby, the control unit 7 determines whether or not a predetermined high-speed recording inhibition time has elapsed since the previous high-speed dubbing (step S201).

When it is determined that the elapsed time has not elapsed (step S201; NO), the control unit 7 acquires the remaining time until the high-speed recording inhibition time elapses from the timer 5. Then, the control unit 7 controls the display unit 6 to display the obtained remaining time (step S202), and ends the high-speed dubbing process.

On the other hand, if it is determined that the elapsed time has elapsed (step S201; YES), the control section 7 controls the CD reproduction section 1 and the MD recording / reproduction section 2 to set the disc number and the track number indicated by the dubbing signal. High-speed dubbing of the recorded music data to the MD is performed (step S203), and the high-speed dubbing process ends. When starting high-speed dubbing, the control unit 7 sets a predetermined high-speed recording prohibition time in the timer 5 and causes the timer 5 to start counting the high-speed recording prohibition time.

FIG. 4 is a flowchart showing the AI dubbing process performed by the control unit 7. First, the control unit 7
Determines whether the timer 5 is counting the high-speed recording inhibition time. Thereby, the control unit 7 determines whether or not a predetermined high-speed recording inhibition time has elapsed since the previous high-speed dubbing (step S301).

When it is determined that the time has passed (step S
301; YES), the control unit 7 controls the CD playback unit 1 and the MD
The recording / reproducing unit 2 is controlled so that the music data recorded on the disc number and the track number indicated by the dubbing signal is
D is dubbed at a high speed (step S302), and the AI dubbing process ends. When starting high-speed dubbing, the control unit 7 sets a predetermined high-speed recording prohibition time in the timer 5 and causes the timer 5 to start counting the high-speed recording prohibition time.

On the other hand, if it is determined that the elapsed time has not elapsed (step S301; NO), the control section 7 will dub the music data indicated by the dubbing signal from the input section 3 earlier, in either normal dubbing or high-speed dubbing. It is determined whether or not it can be performed (step S303). In other words, the control unit 7 performs the normal dubbing without waiting for the high-speed recording prohibition time to elapse or the high-speed dubbing after the high-speed recording prohibition time elapses. Determine if you can.

Specifically, the control unit 7 obtains the remaining time from the timer 5 until the high-speed recording prohibition time elapses.
Further, the control unit 7 controls the CD-TOC stored in the memory 4.
The individual reproduction time of the music data to be dubbed is obtained from the information.

The control unit 7 controls the time required for normal dubbing without waiting for the elapse of the high-speed recording prohibition time (normal dubbing time) and the time required for waiting for the elapse of the high-speed recording prohibition time and then performing the high-speed dubbing. Time (remaining time of high-speed recording inhibition time) + (high-speed dubbing time), respectively.

Thereafter, the controller 7 determines which of (remaining time of high-speed recording inhibition time) + (high-speed dubbing time) and (normal dubbing time) is shorter. Thereby, the control unit 7 determines which of the normal dubbing and the high-speed dubbing can dub the music data faster.

When it is determined that the normal dubbing is earlier (step S303; normal), the control unit 7 controls the CD reproducing unit 1 and the MD recording / reproducing unit 2 to set the disc number and the track number indicated by the dubbing signal. Normally dubbing the recorded music data to the MD (step S304),
The AI dubbing process ends.

On the other hand, when it is determined that the high-speed dubbing is faster (step S303; high-speed), the control unit 7 waits until the timer 5 finishes counting the high-speed recording inhibition time. Then, after the counting of the high-speed recording prohibition time is completed, the control unit 7 controls the CD reproduction unit 1 and the MD recording / reproduction unit 2 so that the music data recorded on the disk number and the track number indicated by the dubbing signal is reproduced. High-speed dubbing is performed on the MD (step S305), and the AI dubbing process ends. When starting high-speed dubbing, the control unit 7 sets a predetermined high-speed recording prohibition time in the timer 5,
To start counting the high-speed recording prohibition time.

(Specific Example) Next, AI dubbing performed by the recording / reproducing apparatus will be described with a specific example. 1. Specific Example 1 First, the users of the recording / reproducing apparatuses are different CDs.
A case in which three pieces of music data recorded in the DVD are dubbed to an MD will be described. High-speed dubbing is performed at twice the speed of normal dubbing. The remaining time of the high-speed recording prohibition time is 30 minutes. Also, the dubbing destination M
D does not record any music data.

The user of the recording / reproducing apparatus sets three CDs on which music data to be dubbed are recorded in the CD reproducing unit 1 and sets the dubbing destination MD in the MD recording / reproducing unit 2. The CD reproducing section 1 reproduces the TOC information recorded on each set CD, generates, for example, the CD-TOC information shown in FIG.

The MD recording / reproducing section 2 reproduces the TOC information recorded on the set MD, for example, as shown in FIG.
Is generated and output to the control unit 7. The controller 7 controls the CD-T supplied from the CD player 1
OC information and MD supplied from MD recording / reproducing unit 2
-Store the TOC information in the memory 4.

After setting the CD and MD, the user of the recording / reproducing apparatus operates the input button or the like of the input unit 3 to select the dubbing mode, and selects the dubbing mode of the CD on which the music data to be dubbed is recorded. Input the disc number and track number in the order of dubbing.

Specifically, the user of the audio device
The AI mode is selected as the dubbing mode. In addition, the user first inputs the disk 2 and the track 1,
The disk 3 and track 3 are input second, and the disk 1 and track 2 are input third.

The input section 3 outputs to the control section 7 a dubbing signal indicating a dubbing mode, a disc number, a track number and the like selected or inputted by the user. This allows
First, the music data recorded on track 1 of disk 2 is dubbed, and second, track 3 of disk 3
Is set to be dubbed, and the third is to dub the song data recorded on track 2 of the disk 1.

The control section 7 starts the dubbing process shown in FIG. 2 in response to the dubbing signal supplied from the input section 3. First, the control unit 7 determines whether the dubbing mode indicated by the dubbing signal is a normal mode, a high-speed mode, or an AI mode (step S101).

In this case, the controller 7 determines that the mode is the AI mode (step S101; AI), and sets the AI mode shown in FIG.
A dubbing process is performed (step S104). First, the control unit 7 determines whether the predetermined high-speed recording prohibition time has elapsed since the previous high-speed dubbing by determining whether the timer 5 is counting the high-speed recording prohibition time. (Step S301).

In this case, the control unit 7 determines that the elapsed time has not elapsed (step S301; NO), and performs normal dubbing without waiting for the high-speed recording prohibition time to elapse and waits for the high-speed recording prohibition time to elapse. In order to perform high-speed dubbing, it is determined which one can dub the music data earlier (step S303).

More specifically, the control unit 7 obtains the remaining time from the timer 5 until the high-speed recording prohibition time elapses.
Further, the control unit 7 acquires the individual reproduction time of the music data to be dubbed from the CD-TOC information in the memory 4. In this case, the remaining time of the high-speed recording prohibition time is 30 minutes, and the individual reproduction times of the music data to be dubbed are 10 minutes, 14 minutes, and 10 minutes, respectively.

The control unit 7 controls the time required for normal dubbing without waiting for the elapse of the high-speed recording prohibition time (normal dubbing time) and the time required for high-speed dubbing after the elapse of the high-speed recording prohibition time. Time (remaining time of high-speed recording inhibition time) + (high-speed dubbing time), respectively. In this case, (the normal dubbing time) is 34 minutes, and ((the remaining time of the high-speed recording inhibition time) + (high-speed dubbing time)) is 30 + 17 = 47 minutes.

Therefore, the control unit 7 determines that the music data can be dubbed earlier if the normal dubbing is performed without waiting for the elapse of the high-speed recording inhibition time (step S303; normal). Then, the control unit 7 controls the CD reproducing unit 1 and the MD recording / reproducing unit 2 to normally dub the music data recorded on the disk number and the track number indicated by the dubbing signal to the MD (step S304), The dubbing process ends.

As described above, in the AI mode, the recording / reproducing apparatus selects a method by which predetermined music data can be dubbed earlier from the remaining time of the high-speed recording inhibition time. Therefore, the user of the recording / reproducing apparatus can easily and efficiently dub the music data simply by selecting the AI mode.

2. Specific Example 2 Next, a case where the remaining time of the high-speed recording inhibition time is 10 minutes will be described. The user of the recording / reproducing apparatus dubs three pieces of music data recorded on different CDs to the MD, as in the specific example 1. High-speed dubbing is performed at twice the speed of normal dubbing. Also, no music data is recorded in the dubbing destination MD.

The user of the recording / reproducing apparatus sets three CDs on which music data to be dubbed are recorded in the CD reproducing section 1 and sets the MD as the dubbing destination in the MD recording / reproducing section 2. The CD reproducing section 1 reproduces the TOC information recorded on each set CD, generates, for example, the CD-TOC information shown in FIG.

The MD recording / reproducing unit 2 reproduces the TOC information recorded on the set MD, for example, as shown in FIG.
Is generated and output to the control unit 7. The controller 7 controls the CD-T supplied from the CD player 1
OC information and MD supplied from MD recording / reproducing unit 2
-Store the TOC information in the memory 4.

After setting the CD and MD, the user of the recording / reproducing apparatus selects the AI mode as the dubbing mode as in the first embodiment. Also, the user inputs the disk 2 and the track 1 first, as in the specific example 1,
The disk 3 and track 3 are input second, and the disk 1 and track 2 are input third.

The input unit 3 outputs to the control unit 7 a dubbing signal indicating a dubbing mode, a disc number, a track number and the like selected or inputted by the user. This allows
First, the music data recorded on track 1 of disk 2 is dubbed, and second, track 3 of disk 3
Is set to be dubbed, and the third is to dub the song data recorded on track 2 of the disk 1.

The control section 7 starts the dubbing process shown in FIG. 2 in response to the dubbing signal supplied from the input section 3. First, the control unit 7 determines whether the dubbing mode indicated by the dubbing signal is a normal mode, a high-speed mode, or an AI mode (step S101).

Also in this case, the control unit 7 determines that the mode is the AI mode (step S101; AI), and sets the A mode shown in FIG.
An I dubbing process is performed (step S104). At the beginning,
The controller 7 determines whether or not the predetermined high-speed recording prohibition time has elapsed since the previous high-speed dubbing by determining whether or not the timer 5 is counting the high-speed recording prohibition time (step S301).

In this case, the control unit 7 determines that the elapsed time has not elapsed (step S301; NO), and performs the normal dubbing without waiting for the elapse of the high-speed recording inhibition time and the high-speed In the case of performing high-speed dubbing after waiting for the lapse of the recording prohibition time, it is determined which of the music data can be dubbed earlier (step S30).
3).

More specifically, the control unit 7 obtains the remaining time until the high-speed recording prohibition time elapses from the timer 5 and calculates the individual reproduction time of the music data to be dubbed from the CD-TOC information in the memory 4. get.

In this case, the remaining time of the high-speed recording inhibition time is 10 minutes, and the individual reproduction times of the music data to be dubbed are 10 minutes, 14 minutes, and 10 minutes, respectively. From this, (normal dubbing time) is 34 minutes, and (remaining time of high-speed recording prohibition time) + (high-speed dubbing time) is:
10 + 17 = 27 minutes.

Accordingly, the control section 7 determines that the music data can be dubbed earlier if the high-speed dubbing is performed after the elapse of the high-speed recording prohibition time (step S303; high-speed). Then, the control unit 7 waits until the timer 5 finishes counting the high-speed recording inhibition time. In this way, the dubbing waits (reserves) until the high-speed recording prohibition time has elapsed.

After the high-speed recording inhibition time has elapsed, the control unit 7
Controls the CD reproducing unit 1 and the MD recording / reproducing unit 2 to perform high-speed dubbing of music data recorded on the disk number and the track number indicated by the dubbing signal to the MD (step S305), and ends the AI dubbing process. . When starting high-speed dubbing, the control unit 7 sets a predetermined high-speed recording prohibition time in the timer 5 and causes the timer 5 to start counting the high-speed recording prohibition time.

As described above, in the AI mode, the recording / reproducing apparatus selects a method by which predetermined music data can be dubbed earlier from the remaining time of the high-speed recording inhibition time. Therefore, the user of the recording / reproducing apparatus can easily and efficiently dub the music data simply by selecting the AI mode.

It should be noted that the above-mentioned recording / reproducing apparatus uses a CD to MD
The present invention can be applied not only to dubbing of music data to programs, but also to dubbing of programs and data. For example, the present invention can be applied to a case where image data or a program is dubbed on a recording medium such as a CD-ROM or a DVD-ROM.

The device of the present invention does not need to use a dedicated device, and can be realized by a normal 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. Thus, the device of the present invention can be realized. The distribution of programs and data is not limited to CD-ROM, etc.
It may be performed via a communication line or the like.
