BACKGROUND OF THE INVENTION
The present invention relates to a recording / reproducing apparatus and a music data recording method.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a recording / reproducing apparatus capable of recording (recording) music data (audio signal) obtained by reproducing a CD (compact disc) or the like on an MD (mini disc) or the like is known. In such a recording / playback apparatus, for example, a CD playback mechanism and an MD recording (playback) mechanism are provided in one device, and the MD quality of music data played back by the CD playback mechanism is hardly degraded. Recording can be performed on a predetermined MD by a recording mechanism. In addition, after recording on the MD, editing such as changing the order of the music data is easy, so it is widely used.
[0003]
Recently, a technique for recording a large number of music data on an MD or the like by a high compression method such as ATRAC3 (Adaptive TRansform Acoustic Coding 3) has been put into practical use. For example, a recording / reproducing apparatus having an MD recording mechanism corresponding to MDLP (long-time recording mode) can record music data for five music CDs with high compression on one MD.
On the other hand, there is also known a recording / reproducing apparatus capable of recording music data reproduced at high speed (high-speed reproduction) with a CD reproduction mechanism at high speed (high-speed recording) with an MD recording mechanism. Such a recording / reproducing apparatus can shorten the time required for recording, and can record more music pieces within the same time.
[0004]
[Problems to be solved by the invention]
In the conventional recording / reproducing apparatus corresponding to the above-mentioned long-time recording and high-speed recording, the user can freely set recording conditions such as a recording mode and a recording speed.
For example, when the recording / reproducing apparatus supports the normal recording mode (stereo), the normal recording mode (monaural), the long-time recording mode (LP2), and the long-time recording mode (LP4). Sets one of the four recording modes as a recording condition and starts the recording operation.
Also, for example, when the recording / playback apparatus can record music data at a normal recording speed, a double speed recording speed, and a quadruple speed recording speed, the user can select one of the three Set the recording speed as the recording condition and start the recording operation.
[0005]
The recording conditions set in this way are not always the same every time.
For example, when a user intends to make an MD to listen to during driving, the long-time recording mode (LP4) is set as a recording condition in order to record as much music data as possible on the MD. Also, when making an MD to listen carefully in your room, the normal recording mode (stereo) is set as the recording condition in order to record the music data as faithful as possible to the original sound in the MD.
That is, the user needs to sequentially change the recording conditions set in the recording / reproducing apparatus according to the purpose and the like.
However, such a change in the recording condition setting is very complicated for the user because generally a large number of complicated key operations have to be performed.
[0006]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a recording / reproducing apparatus and a music data recording method capable of recording music data and the like by easily changing recording conditions.

DETAILED DESCRIPTION OF THE INVENTION
A recording / reproducing apparatus according to an embodiment of the present invention will be described below with reference to the drawings.
[0013]
FIG. 1 is a block diagram showing an example of a recording / reproducing apparatus applied to the embodiment of the present invention. As shown in the figure, the recording / reproducing apparatus 1 is an audio device that reproduces music data recorded on a CD (compact disc) 2 and records the reproduced music data on an MD (mini disc) 3 in a predetermined recording mode. Yes, a CD drive unit 11, a CD DSP 12, an input key 13, a display 14, an MD drive unit 15, an MD DSP 16, a microcomputer 17, D / A 18, 20, and A / D 19 And an output switching SW 21.
[0014]
The CD drive unit 11 is, for example, a drive unit including a bank mechanism that can store three CDs 2 (CD2a to 2c), and transports any CD2 stored in the bank mechanism onto a turntable to be stored in the CD2. Play the recorded music data.
Specifically, as shown in FIG. 2, the CD drive unit 11 includes a carry-in / carry-out mechanism 11a, a bank mechanism 11b, a transport mechanism 11c, a turntable 11d, and a pickup 11e.
The carry-in / carry-out mechanism 11a carries the CD 2 inserted by the user through a predetermined insertion port into the bank mechanism 11b. Further, the CD 2 stored in the bank mechanism 11b is carried out to the insertion slot.
[0015]
The bank mechanism 11b includes, for example, banks (banks bk1 to bk3) for storing three CD2s, and stores the CD2 loaded by the loading / unloading mechanism 11a in a predetermined bank. Further, the bank mechanism 11b transports the CD2 stored in the bank to be reproduced onto the turntable 11d via the transport mechanism 11c.
The transport mechanism 11c takes out the CD2 from the target bank (banks bk1 to bk3) in the bank mechanism 11b and transports it to the turntable 11d. Also, the CD 2 mounted on the turntable 11d is removed and transported to the original bank of the bank mechanism 11b.
[0016]
The turntable 11d is driven by a predetermined drive motor, and rotates at a predetermined rotational speed (for example, constant linear speed) while the CD 2 transported by the transport mechanism 11c is mounted.
The pickup 11e reads music data (CD audio signal) from the CD2 by irradiating the recording surface of the CD2 mounted on the turntable 11d with laser light having a predetermined wavelength and reading the reflected light.
[0017]
Returning to FIG. 1, the CD DSP (digital signal processor) 12 controls the CD drive unit 11 to reproduce the music data recorded on the CD 2. Specifically, the CD DSP 12 decodes the CD audio signal read by the pickup 11e and reproduces the digital audio signal from the CD2. The CD DSP 12 supplies the reproduced digital audio signal to the MD DSP 16 and the D / A 18.
[0018]
The input key 13 includes a plurality of key switches and the like, and inputs an operation instruction from the user and supplies it to the microcomputer 17.
For example, the input key 13 includes a predetermined numeric keypad (numeric key), and inputs information for selecting a bank (banks bk1 to bk3) to be stored when the user inserts the CD2 from the insertion slot. The input key 13 also includes a “rec key” for instructing a recording operation of music data from CD2 to MD3.
[0019]
The display 14 is composed of a fluorescent display tube or the like and displays information indicating the operation status of the recording / reproducing apparatus 1. For example, the display 14 displays information indicating a recording mode (such as a normal recording mode or a long-time recording mode) when recording music data on the MD 3.
[0020]
The MD drive unit 15 includes, for example, an MD slot-in mechanism, a pickup mechanism, a recording head, and an RF amplifier. The MD drive unit 15 is controlled by the MD DSP 16, records music data on the MD 3, and reproduces music data from the MD 3.
The MD drive unit 15 is a unit corresponding to the long-time recording mode (MDLP). As an example, the normal recording mode (stereo), the normal recording mode (monaural), the long-time recording mode (LP2), and the long The music data can be recorded on the MD 3 in the four recording modes of the time recording mode (LP4).
[0021]
The MD DSP 16 temporarily stores the digital audio signal supplied from the CD DSP 12 in, for example, a built-in DRAM (dynamic ram), and uses this digital audio signal to encode the MD audio signal (ATRAC encoding or , ATRAC3 encoding) processing. The MD DSP 16 controls the MD drive unit 15 and records the music data generated by the encoding process in the MD 3.
Further, the MD DSP 16 controls the MD drive unit 15 to reproduce the music data recorded on the MD 3. Specifically, the MD DSP 16 reproduces a digital audio signal from the MD 3 by a decoding (ATRAC decoding or ATRAC 3 decoding) process. The MD DSP 16 supplies the reproduced digital audio signal to the D / A 20 or the like.
[0022]
The microcomputer 17 is a processing arithmetic unit including an SRAM (static ram) 17a and the like, and controls the entire recording / reproducing apparatus 1.
Specifically, the microcomputer 17 controls the CD DSP 12 so that the CD drive unit 11 reproduces the CD2 stored in each bank (banks bk1 to bk3) in the bank mechanism 11b. In addition, the microcomputer 17 records the reproduced music data in the MD 3 by the MD drive unit 15 by controlling the MD DSP 16 in parallel.
[0023]
At that time, the microcomputer 17 records the music data on the MD 3 according to the recording conditions determined according to the bank (banks bk1 to bk3) in which the CD 2 to be reproduced is stored.
In other words, the SRAM 17a stores a recording condition table 17T that defines recording modes determined corresponding to the banks bk1 to bk3 as shown in FIG. Then, the microcomputer 17 refers to the recording condition table 17T, identifies the recording mode corresponding to the bank in which the CD 2 to be reproduced is stored, and records the music data on the MD 3 in the identified recording mode.
Note that the contents of the recording condition table 17T stored in the SRAM 17a may be appropriately changed according to the operation of the input key 13 by the user.
[0024]
The D / A (digital analog converter) 18 converts the digital audio signal supplied from the CD DSP 12 into an analog audio signal, and outputs the converted analog audio signal to an external device via the output switching SW 21.
[0025]
An A / D (analog / digital converter) 19 converts an analog audio signal supplied from an external device into a digital audio signal, and supplies the converted digital audio signal to the MD DSP 16 or the like.
[0026]
The D / A 20 converts the digital audio signal supplied from the MD DSP 16 into an analog audio signal, and outputs the converted analog audio signal to an external device via the output switch SW21.
[0027]
The output switching SW (switch) 21 is controlled by the microcomputer 17 and selects either the CD audio signal supplied via the D / A 18 or the MD audio signal supplied via the D / A 20. Output to a speaker etc. not shown.
[0028]
The operation of the recording / reproducing apparatus 1 according to the embodiment of the present invention will be described below with reference to FIG. FIG. 4 is a flowchart for explaining the music data recording process executed by the microcomputer 17. The music data recording process is started when, for example, a CD 2 to be reproduced is inserted from a predetermined insertion slot by a user with a recordable MD 3 loaded in the recording / reproducing apparatus 1. Is done.
[0029]
First, the microcomputer 17 acquires information indicating the selected storage destination bank (bk1 to bk3) via the input key 13 (step S11). For example, when the reproduction target CD 2 is inserted from a predetermined insertion slot, the microcomputer 17 acquires information indicating the selected storage destination bank by pressing the numeric keypad of the input key 13.
[0030]
The microcomputer 17 determines whether or not the bank bk1 is selected (step S12). For example, when the user presses the “1” key of the numeric keypad with the input key 13, the microcomputer 17 determines that the bank bk1 has been selected.
[0031]
When determining that the bank bk1 is selected, the microcomputer 17 reads information (recording mode information) indicating the normal recording mode (stereo) from the recording condition table 17T stored in the SRAM 17a (step S13).
The microcomputer 17 controls the loading / unloading mechanism 11a and the like via the CD DSP 12, and stores the CD2 in the bank bk1 of the bank mechanism 11b.
[0032]
On the other hand, when determining that the bank bk1 is not selected, the microcomputer 17 determines whether or not the bank bk2 is selected (step S14). For example, when the user presses the “2” key of the numeric keypad with the input key 13, the microcomputer 17 determines that the bank bk2 has been selected.
[0033]
If the microcomputer 17 determines that the bank bk2 is selected, the microcomputer 17 reads information indicating the long-time recording mode (LP2) from the recording condition table 17T (step S15). Then, the microcomputer 17 controls the carry-in / carry-out mechanism 11a and the like to store the CD2 in the bank bk2.
[0034]
On the other hand, when determining that the bank bk2 is not selected, the microcomputer 17 determines whether or not the bank bk3 is selected (step S16). For example, when the user presses the “3” key of the numeric keypad with the input key 13, the microcomputer 17 determines that the bank bk3 is selected.
[0035]
If the microcomputer 17 determines that the bank bk3 has been selected, the microcomputer 17 reads recording mode information indicating the long-time recording mode (LP4) from the recording condition table 17T (step S17). Then, the microcomputer 17 controls the carry-in / carry-out mechanism 11a and the like, and stores the CD2 in the bank bk3.
[0036]
On the other hand, when it is determined that the bank bk3 is not selected, the microcomputer 17 generates an input error and a message prompting reselection, and displays the message on the display 14 (step S18). Then, the microcomputer 17 returns the process to step S11 described above.
[0037]
When the recording mode information corresponding to the bank (banks bk1 to bk3) is read in any of the above-described steps S13, S15, and S17, the microcomputer 17 receives information for instructing the recording start via the input key 13. It waits for execution of subsequent processing until it is input (step S19).
For example, when the “rec key” is pressed, the microcomputer 17 determines that information for instructing recording is input.
[0038]
When the information for instructing the recording start is input, the microcomputer 17 starts the reproduction of the CD2 in the target bank, and records the reproduced music data in the MD3 according to the recording mode (step S20).
That is, when reproducing the CD 2 stored in the bank bk1, the microcomputer 17 records the reproduced music data on the MD 3 in the normal recording mode (stereo). Further, when the CD2 stored in the bank bk2 is reproduced, the recording is performed in the long-time recording mode (LP2), and when the CD2 stored in the bank bk3 is reproduced, the long-time recording mode (LP4) is recorded. ) To record the music data in MD3.
[0039]
As described above, the music data can be recorded under desired recording conditions without performing a complicated key operation or the like by the music data recording process.
Further, by simply selecting the CD 2 stored in the bank mechanism 11b to be reproduced, it is possible to easily change the recording conditions and record the music data on the MD3.
[0040]
In the above embodiment, the music condition data is recorded in the recording mode corresponding to the banks bk1 to bk3 by storing the recording condition table 17T defining the recording mode as shown in FIG. The recording condition is not limited to the recording mode and is arbitrary.
For example, the music data may be recorded on the MD 3 at a recording speed corresponding to the banks bk1 to bk3 by storing a recording condition table that defines the recording speed as shown in FIG. 5 in the SRAM 17a.
In this case, the microcomputer 17 refers to the recording condition table, specifies the recording speed corresponding to the bank in which the CD 2 to be reproduced is stored, and records the music data on the MD 3 at the specified recording speed.
[0041]
In the above embodiment, the CD drive unit 11 on the CD2 playback side is provided with the bank mechanism 11b and the like, and the music data is recorded on the MD3 in the recording mode corresponding to the banks bk1 to bk3 storing the CD2. On the contrary, a bank mechanism or the like may be provided in the MD drive unit 15 on the recording (recording) side of MD3.
[0042]
For example, as shown in FIG. 6A, the CD drive unit 11 can reproduce only one CD2 without providing a bank mechanism. On the other hand, as shown in FIG. 6B, the MD drive unit 15 is provided with a bank mechanism to store three MD3s (MD3a to 3c). That is, a bank mechanism 15b or the like that can store three MD3s as shown in FIG. 6C is added to the MD drive unit 15.
Similarly, the SRAM 17a stores a recording condition table that defines recording modes and the like corresponding to the banks bk1 to bk3 of the bank mechanism 15b.
Then, the microcomputer 17 refers to the recording condition table and records the music data reproduced from the CD 2 on the MD 3 in a recording mode or the like determined according to the bank (bk1 to bk3) in which the MD 3 to be recorded is stored. .
[0043]
That is, as shown in FIG. 6C, when the MD3 to be recorded is stored in the bank bk1, the microcomputer 17 records the music data on the MD3 in the normal recording mode (stereo). Is stored in the bank bk2, the music data is recorded in the MD3 in the long recording mode (LP2), and the music is recorded in the long recording mode (LP4) when the MD3 is stored in the bank bk3. Data is recorded on MD3.
[0044]
Also in this case, music data can be recorded under desired recording conditions without performing complicated key operations. Further, by simply selecting the MD3 stored in the bank mechanism 15b to be recorded, it is possible to easily change the recording conditions and record the music data on the target MD3.
[0045]
In the above-described embodiment, an apparatus has been described in which the CD drive unit 11 and the MD drive unit 15 are provided with the bank mechanism 11b and the like that can store three CDs and the like. The possible number is arbitrary as long as it is plural.
[0046]
In the above embodiment, the recording / reproducing apparatus 1 that records the music data reproduced from the CD 2 on the MD 3 has been described. However, the reproduction target and the recording target medium are not limited to these CDs and MDs, and other CD- R (CD Recordable), CD-RW (CD ReWritable), MO (Magneto-Optical disk), DVD (Digital Versatile Disk), etc. may be used. Further, it may be a recording / reproducing apparatus capable of editing a medium such as SmartMedia (trademark), Memory Stick (trademark), MMC (Multi Media Card).
[0047]
