Next, music information (a plurality of music pieces) recorded on the DVD audio disk DK loaded on the DVD-ROM drive 11 or the MD loaded on the MD drive 12 by the information recording / reproducing apparatus S shown in FIG. including.)
With reference to FIG. 2, the information recording / reproducing process of the present invention for reproducing and reproducing the data on the hard disk HD will be described.

FIG. 2 is a flowchart showing the information recording / reproducing process. Further, the information recording / reproducing process is mainly executed by the CPU 6 based on a program (stored in the ROM 7 in advance) corresponding to the flowchart shown in FIG.

As shown in FIG. 2, in the information recording / reproducing process of the embodiment, first, the DVD-ROM drive 11
Alternatively, a DVD audio disc DK or MD (hereinafter simply referred to as a disc D) in which music information is recorded on the MD drive 12.
Called K. ) Is determined (step S1).

When the disc is not loaded (step S1; N), the process waits until the disc is loaded (step S1; Y). The data is read out and temporarily stored in the RAM 8 (step S2).

Here, the identification information is, specifically,
The TOC (Table Of Contents) information (in the case of a CD), the U-TOC (User-TOC) information (in the case of an MD), or the DVD audio disc DK itself as table of contents information of each song in the recorded music information. ID (Identificati
on) Says information.

Next, based on the acquired identification information, it is determined whether or not the currently loaded disk DK is a disk DK in which the music information recorded on the disk DK has not been copied to the hard disk HD at all. Is determined (step S3).

If the loaded disk DK is a disk DK to be reproduced for the first time without any copying and recording (step S3; Y), the input device 10 then reads the data in the disk DK. It is determined whether or not start of reproduction of music information has been instructed (step S
4) When the reproduction start is not instructed (step S
4; N) Wait until instructed.

On the other hand, if it is determined in step S4 that reproduction is instructed (step S4; Y), then
The identification information stored in the RAM 8 in step S2 is recorded on the hard disk HD via the HD drive 23 (step S5).

Then, detection of music information recorded on the disk DK and copy recording to the hard disk HD via the bus 9 and the HD drive 28 are started (step S6). Thereafter, based on the content of the reproduction start instruction in step S4, reproduction of music information copied and recorded on the hard disk HD and output to the outside using the sound reproduction unit 18 are started (step S7).

That is, in the processes of steps S6 and S7, while the music information is recorded on the hard disk HD, the recorded music information is immediately reproduced from the hard disk HD.

Here, there are various methods for copying and recording music information to the hard disk HD in step S6, as described below, and the method is appropriately selected by the CPU 6 based on the type of information recording medium, the compression method, and the like. . The form of the music information itself to be copied and recorded is also converted into various forms and copied and recorded on the hard disk HD as described below.

(1) Compress music information and hard disk
In the case of copying and recording in HD, in this case, first, the uncompressed linear PCM
(Pulse Code Modulation) Music CD on which music information is recorded or DVD audio disc D on which uncompressed music information (specifically, a so-called title or the like recorded by the linear PCM music information) is recorded.
K is loaded into the DVD-ROM drive 11, the linear PCM
Music information is read. The read linear PCM music information is compressed by a compression method such as the ATRAC method or the MP3 (MPEG Audio Layer 3) method in the compression unit 23, transferred to the HD drive 28 via the bus line 9, and recorded on the hard disk HD. Is done.

In addition to the method of compressing the linear PCM music information read from the DVD-ROM drive 11 by the compression unit 23, the A / D converter 20 converts the analog signal output from the D / A converter 19 into a digital signal. The signal may be converted into a signal, and then compressed by the compression unit 23 and recorded on the hard disk HD.

(2) Expand the compressed music information to
When copying and recording to a hard disk HD, whether the MD is loaded in the MD drive 12 or the DV
DVD audio disk D in D-ROM drive 11
K (compressed music information is recorded,
In the DVD audio disk DK, due to its standard,
Music information in both uncompressed and compressed states can be recorded. ) Is loaded, the compressed music information reproduced by each drive is expanded by the expansion unit 24.

The expanded music information is stored in a linear PC.
HD drive 2 via bus line 9 as M music information
8 and recorded on the hard disk HD.

It should be noted that the linear P
In addition to the method of recording CM music information on the hard disk HD, a digital signal obtained by digitizing an analog signal output from the D / A converter 19 by the A / D converter 20 may be recorded on the hard disk HD.

Here, although the respective compression systems of the MD and the DVD audio disk DK are different from each other, the decompression unit 24 uses a DSP (Digital Signa) included therein.
l Processor) can expand music information compressed by a plurality of compression methods.

(3) The compressed music information is hard-
When copying and recording on a disc HD, whether the MD is loaded in the MD drive 12 or the DV
DVD audio disk D in D-ROM drive 11
When K (recording compressed music information) is loaded, the compressed music information reproduced by each drive is transferred to the HD drive 28 via the bus line 9,
It is recorded on the hard disk HD.

That is, the music information recorded on the MD or DVD audio disk DK is directly recorded on the hard disk HD.

(4) Changing the compression method of the compressed music information
When copying and recording on a hard disk HD, whether the MD is loaded in the MD drive 12 or the DV
DVD audio disk D in D-ROM drive 11
When K (recording compressed music information) is loaded, the compressed music information reproduced by each drive is transferred to the compression format conversion unit 25 via the bus line 9 and the compression format is converted. Is done. In this case, for example, if the reproduction target is MD, ATRAC which is a compression method of the MD is used.
The format is converted, for example, to the MP3 format.

The compressed music information after the compression format conversion is transferred again to the HD drive 28 via the bus line 9 and recorded on the hard disk HD.

(5) Convert the number of channels and
In the case of copying and recording on the HD, the standard for the DVD audio disk DK specifies that music information can be recorded on the DVD audio disk DK in multi-channels of 5.1 channels. The configuration (for example, the number of speakers in the vehicle compartment) may not be compatible with the multi-channel reproduction.

In this case, it is necessary to down-mix and reproduce multi-channel music information into, for example, two-channel stereo. This downmix processing is performed in the conversion unit 26. At this time, the conversion unit 2
Numeral 6 is constituted by a DSP or the like, and mixes the music information of each channel in the multi-channel at a predetermined ratio set in advance to obtain, for example, 2-channel stereo music information.

Now, the DVD-ROM drive 11
When the audio disk DK (DVD audio disk DK on which multi-channel music is recorded) is loaded, the music information reproduced by the DVD-ROM drive 11 is transferred to the conversion unit 26 via the bus line 9, and
For example, it is converted into music information of two channels stereo.
Then, the data is again transferred to the HD drive 28 via the bus line 9 and recorded on the hard disk HD.

When there is an environment in which multi-channel music information can be reproduced in the vehicle, the music information on the DVD audio disk DK is configured to be recorded on the hard disk HD without changing the multi-channel, and the hard disk HD This may be reproduced and output from the speaker 22 via the D / A converter 19 and the amplifier 21.

(6) Convert the sampling frequency to
When copying and recording on a DVD disc HD, the DVD audio disc DK has a standard of 96 KH
It is defined that music information of a plurality of sampling frequencies such as z or 48 KHz can be recorded.

Here, if the sampling frequency is high, the entire data amount increases, and if such music information is to be recorded on the hard disk HD, the capacity of the hard disk HD is wasted. Therefore, in this case, it is conceivable to record the data on the hard disk HD after reducing the sampling frequency to reduce the amount of data.

In this case, music information with a sampling frequency of, for example, 96 KHz reproduced from the DVD-ROM 11 is transferred to the conversion unit 26 via the bus line 9 and converted into music information with a sampling frequency of, for example, 48 KHz. Then, the music information converted by the conversion unit 26 is transferred again to the HD drive 28 via the bus line 9 and recorded on the hard disk HD.

Copy recording to the hard disk HD is performed by the various methods described above (step S6).

Here, regarding the copy and recording of the music information to the hard disk HD, the copy and recording are started by the user's instruction in the input device 10 as described above. When the reproduction of the music information is started by loading the music information, the copy recording can be automatically started.

The recording speed of the copy recording on the hard disk HD started in step S6 is at least twice the reproduction speed of the music information recorded on the hard disk HD started in the next step S7. Run at speed. Thereby, the sound reproducing unit 1
The copying and recording can be performed while preventing the sound output from the output unit 8 from being interrupted.

The reproduction from the hard disk HD started in step S7 is specifically performed by the HD drive 28. At this time, the music information recorded on the hard disk HD is compressed. At this time, the music information is reproduced / output after being decompressed by the decompression unit 24. On the other hand, when the uncompressed music information is recorded on the hard disk HD, it is decoded as it is to the outside via the sound reproduction unit 18. Output as sound.

At this time, as described above,
Since the decompression unit 24 is configured by the SP, the decompression unit 24 can perform decompression processing corresponding to various compression methods.

Next, it is determined whether or not copying and recording of all music information recorded on the disk DK to the hard disk HD and reproduction of all music information recorded on the hard disk HD have been completed (step S1). S8),
If the operation has been completed (step S8; Y), the process directly proceeds to step S10. If the operation has not been completed (step S8; N), the ACC switch 30 is turned off (that is, the vehicle is It stopped and the engine was turned off)
Thus, it is determined whether or not the copy recording and reproduction have been stopped before the end of the copy recording and reproduction of all the music information in the disk DK (step S9).

When the copying, recording, and reproduction of all the music information in the disc DK are not stopped before the end (Step S9; N), the process returns to Step S8 to continue the copying, recording, and reproduction. When the ACC switch 30 is turned off to stop copying (recording and reproduction) (intermediate stop) (step S9; Y),
Step S8; Y or step S9; the state in which copy recording and reproduction are not performed in Y means that all the music information in the disc DK is copied to the hard disk HD and stopped before the recording and reproduction are completed. (Stop in the middle) is checked (step S1).
0), when it is stopped halfway (step S10; Y),
Song and D that were copied and recorded just before the stop
The identification information for identifying the disk DK loaded in the VD-ROM drive 11 or MD drive 12 is recorded on the hard disk HD (step S11), and the copy, recording, reproduction and output of the music information currently being executed are stopped. (Step S12), and ends the information recording / reproducing process according to the embodiment.

The recording process in step S11 is executed using the power supply supplied from the battery 29 by the backup system.

On the other hand, in the determination of step S3, the DV
If the disc DK loaded in the D-ROM drive 11 or the MD drive 12 is a disc DK for which at least a part of the copy recording and reproduction has been performed (step S3; N), then Recorded on the hard disk HD (see step S11).
The identification information on the disk DK is detected, and it is determined whether or not all the music information recorded on the disk DK is copied and recorded on the hard disk HD (step S13), and only a part of the music information is copied and recorded. When it is determined from the detected identification information that the reproduction and the output have not been completed (step S13; N), copy recording is started from the music following the last recorded music piece (step S14). Further, the reproduction of the music information copied and recorded from the music following the last music copied from the hard disk HD is started (step S15), and the process proceeds to step S8.

On the other hand, when it is determined from the detected identification information that the copying and recording of all the music information have been completed in the determination of step S13 (step S13;
Y) Next, it is determined whether or not reproduction and output start of the music information in the hard disk HD for which the copying and recording have been completed are instructed by the input device 10 (step S1).
6) When the reproduction and output start are not instructed (step S16; N), the process waits until instructed, and when instructed (step S16; Y), the reproduction and output are performed based on the contents of the instruction. It starts (step S17), and proceeds to step S8.

Then, after step S8, the above-described processing is repeated.
