The mini disk 1 is rotationally driven by a spindle motor 2. Reference numeral 3 is an optical head for irradiating a laser beam to the mini disk 1 at the time of recording / reproducing, which provides a high level laser output for heating the recording track to the Curie temperature at the time of recording, and is reflected by the magnetic Kerr effect at the time of reproducing. It provides a relatively low level laser power for detecting data from light.

For this reason, the optical head 3 is equipped with a laser diode as a laser output means, an optical system including a deflecting beam splitter, an objective lens and the like, and a detector for detecting reflected light. The objective lens 3a is held by the biaxial mechanism 4 so as to be displaceable in the disc radial direction and the direction in which the disc moves toward and away from the disc.

Reference numeral 6a denotes a magnetic head for applying a magnetic field modulated by the supplied data to the mini disk, which is arranged at a position facing the optical head 3 with the mini disk 1 interposed therebetween. The entire optical head 3 and the magnetic head 6a are movable in the disk radial direction by the sled mechanism 5.

By the reproducing operation, the information detected from the mini disk 1 by the optical head 3 is supplied to the RF amplifier 7. The RF amplifier 7 calculates a reproduction RF signal, a tracking error signal, a focus error signal, absolute position information (absolute position information recorded as pre-groove (wobbling groove) on the mini disk 1), address by calculation processing of the supplied information. Information, focus monitor signal, etc. are extracted. Then, the extracted reproduction RF signal is supplied to the encoder / decoder unit 8. The tracking error signal and the focus error signal are supplied to the servo circuit 9, and the address information is supplied to the address decoder 10. Further, the absolute position information and the focus monitor signal are supplied to a controller 11 (hereinafter, referred to as MD controller) including a microcomputer, for example.

The servo circuit 9 generates various servo drive signals according to the supplied tracking error signal, focus error signal, track jump command, seek command from the MD controller 11, rotational speed detection information of the spindle motor 2, etc. The axis mechanism 4 and the sled mechanism 5 are controlled to perform focus and tracking control, and the spindle motor 2 is controlled to a constant linear velocity (CLV).

The reproduced RF signal is sent to the encoder / decoder unit 8
After being subjected to EFM demodulation and decoding processing such as CIRC, the memory controller 12 once writes the data in a buffer RAM 13 formed by a D-RAM.
The reading of data from the mini disk 1 by the optical head 3 and the transfer of reproduction data in the system from the optical head 3 to the buffer RAM 13 are 1.41 Mbit / sec, and are intermittently performed.

The data written in the buffer RAM 13 is read out at a timing when the reproduction data is transferred at 0.3 Mbit / sec, and is supplied to the encoder / decoder section 14. Then, the quantized 16-bit output digital signal is obtained by the decoding process for the audio compression process by the modified DCT process. The output digital signal is the D / A converter 15
Is converted into an analog signal and supplied to the terminal 16. Then, it is supplied from the terminal 16 to the _TMD terminal of the switch 65 as described above.

The address information output from the address decoder 10 and the subcode data used for the control operation are supplied to the MD controller 11 via the encoder / decoder section 8 and used for various control operations. Furthermore, a lock detection signal of a PLL circuit that generates a bit clock for recording / reproducing operation, and reproducing data (L and R channels)

Further, the MD controller 11 outputs a laser control signal S _LP for controlling the operation of the laser diode in the optical head 3, controls the output of the laser diode on / off, and at the time of on-control, the laser control signal S _LP. It is possible to switch between an output at the time of reproduction in which the power is at a relatively low level and an output at the time of recording in which the power is at a relatively high level.

When a recording operation is performed on the mini disk 1, an analog audio signal is supplied to the terminal 17. The terminal 17 is a terminal to which an audio signal is supplied via the switch 66. Then, it is supplied to the encoder / decoder unit 14 after being 44,1 KHz sampling and quantized 16-bit digital data in the A / D converter 18.

The encoder / decoder unit 14 performs audio compression encoding by the modified DCT process on the input digital audio signal. Encoder / decoder unit 14
The recording data compressed by the memory controller 1
The data is once written in the buffer RAM 13 by 2, and is read at a predetermined timing and sent to the encoder / decoder unit 8. Then, in the encoder / decoder section 8, the CI
It is supplied to the magnetic head drive circuit 6 after being subjected to encoding processing such as RC encoding and EFM modulation.

The magnetic head drive circuit 6 supplies a magnetic head drive signal to the magnetic head 6a according to the encoded recording data. That is, the magnetic field of N or S is applied to the mini disk 1 by the magnetic head 6a. At this time, the MD controller 11 also supplies a control signal to the optical head so as to output a laser beam of a recording level.

The MD controller 11 is composed of a microcomputer for controlling various operations such as recording / playback / editing. Then, by the input unit 63, M
When the D recording / reproducing unit 30 is operated, the controller 60 supplies a control signal according to the operation information to the MD controller 11. The MD controller 11 controls the operation of each part shown in FIG. 2 according to this control signal.

The MD controller 11 is a mini disc 1
When performing a recording / reproducing operation with respect to, the management information recorded on the mini disc 1, that is, P-TOC (pre-mastered TOC) and U-TOC (user TOC),
It is read into the buffer RAM 13. For example, this reading is performed when the disc is loaded. Therefore, the buffer RAM
13, the recording data / playback data buffer area and the area for holding the management information are divided and set. The MD controller 11 discriminates the recordable area on the disc 1 and the address of the track to be reproduced according to the management information read into the buffer RAM 13 to perform various controls.

The U-TOC is edited and rewritten in response to recording or erasing of data, but the MD controller 11 performs this editing process every time recording / erasing operation is performed by the U-TOC stored in the buffer RAM 13. After the TOC information, the buffer RA is executed at a predetermined timing.
The U-TOC on the M13 is recorded in the U-TOC area of the mini disc 1.

3. P-TOC sector 0 of the mini-disc management information Here, as the management information for managing the recording / reproducing operation of the track in the mini-disc 1, first, the P-TO
The C sector will be described. As the P-TOC information, area designation such as a recordable area (recordable user area) of the disc and management of the U-TOC area are performed. If the mini disc 1 is a pre-mastered disc that is a read-only optical disc, PT
The music recorded in the ROM by the OC can also be managed.

FIG. 11 shows one sector (sector 0) of the P-TOC information repeatedly recorded in the area for P-TOC (for example, the ROM area on the innermost circumference side of the disc). The P-TOC sector exists from sector 0 to sector 7, but sector 1 and later are optional.

The data area of P-TOC sector 0 (4 bytes x 588 2352 bytes) has all 0s at the head position.
Alternatively, a synchronization pattern composed of 1-byte data of all 1s, an address indicating a cluster address and a sector address, and the like are added by 4 bytes, and the header is formed. In addition, following the header, "MIN
Identification by ASCII code corresponding to the letter "I" I
D is added to indicate that it is a region of P-TOC.

Then, the disc type, recording level, song number of the first song recorded (First TNO), song number of the last song (Last TNO), lead-out start address LO _A , power cal area start Address P
C _A, U-TOC start address UST _A, a start address RST _A, etc. recordable area (recordable user area) is recorded.

Subsequently, a corresponding table instruction data section having table pointers (P-TNO1 to P-TNO255) for making each music recorded in the pit form correspond to a parts table in a management table section described later is prepared. There is.

Then, in the area subsequent to the correspondence table instruction data portion, (01h) to (FF) corresponding to the table pointers (P-TNO1 to P-TNO255) in the correspondence table instruction data portion.
A management table section is prepared, which has 255 parts tables up to h). In this specification, "h"
Numerical values marked with are in so-called hexadecimal notation. In each part table, a start address as a starting point, an end address as an ending point, and mode information (track mode) of the part can be recorded for a certain part.

The mode information of the track in each parts table records, for example, information as to whether the part is set to overwrite inhibition or data copy inhibition, whether it is audio information, or monaural / stereo type. Has been done.

In each part table from (01h) to (FFh) in the management table section, the contents of the part are indicated by the table pointers (P-TNO1 to P-TNO255) in the corresponding table instruction data section. That is, a certain parts table (for example, (01h)) is recorded as the table pointer P-TNO1 for the first piece of music, and in this case, the start address of the parts table (01h) is the recording position of the first piece of music. And the end address is the end address of the position where the first music piece is recorded. Further, the track mode information becomes information about the first music piece. Actually, the table pointer has a numerical value that can indicate a certain parts table at the byte position in the P-TOC sector 0 by a predetermined calculation process.

Similarly, for the second piece of music, the parts table indicated by the table pointer P-TNO2 (eg (02h))
The start address, end address, and track mode information of the recording position of the second tune are recorded in. Similarly, since the table pointers up to P-TNO255 are prepared, it is possible to manage up to the 255th song on the P-TOC. Then, by forming the P-TOC sector 0 in this way, a predetermined music piece can be accessed and reproduced, for example, during reproduction.

In the case of a recordable / reproducible mini disk, since there is no so-called pre-mastered music area, the above-mentioned correspondence table instruction data section and management table section are not used (these are the U-TOC which will be described subsequently).
Therefore, each byte is all “00h”. However, for pre-mastered type discs in which all songs are recorded in ROM form (pit form), and hybrid type discs having both ROM area and magneto-optical area as areas for recording songs, etc., The correspondence table instruction data section and the management table section are used to manage the music in the ROM area.

U-TOC sector 0 Next, the sector 0, sector 1, and sector 2 of the U-TOC will be described as U-TOC. Note that U
-TOC sectors are also provided from sector 0 to sector 7, but sector 3 and sectors 5 to 7 are undefined.

FIG. 12 shows the format of the U-TOC sector 0, which is mainly a data area in which management information about the music recorded by the user and the free area in which new music can be recorded is recorded. It For example, when trying to record a song on the Mini Disc 1,
The MD controller 11 finds a free area on the disc from the U-TOC sector 0 and records audio data there. Also, at the time of reproduction, the area in which the music to be reproduced is recorded is the U-TOC sector 0.
Then, the area is accessed and a reproducing operation is performed.

In the U-TOC sector 0 shown in FIG. 12,
Like the P-TOC, a header is provided first, and then a manufacturer code, model code, song number of the first song (First TNO), song number of the last song (Last TN) at a predetermined address position.
O), sector usage status (Used sectors), disk serial number, disk ID and other data are recorded.

Further, in order to identify the area of music recorded by the user by recording and the free area by associating with the management table section described later, various table pointers (P
-The area for recording DFA, P-EMPTY, P-FRA, P-TNO1 to P-TNO255) is prepared.

Then, the table pointer (P-DFA to P-TNO25
As the management table section that will correspond to (5) (01h)
Up to 255 (FFh) parts tables are provided, and each parts table has P-
Similar to the TOC sector 0, a start address as a starting point, an end address as an ending point, and mode information (track mode) of the part are recorded for a certain part. Further, in the case of this U-TOC sector 0, the parts shown in each parts table may be connected to other parts in succession, so the start and end addresses of the connected parts are recorded in the parts table. The link information indicating the can be recorded.

In this type of recording / reproducing apparatus, the reproduction operation is impeded by physically discontinuously reproducing the data of one music piece, that is, even if the data is recorded over a plurality of parts, the parts are accessed while being reproduced. Therefore, the music recorded by the user may be recorded in multiple parts for the purpose of efficiently using the recordable area.

Therefore, the link information is provided, and the parts tables can be connected by designating the parts tables to be connected by the numbers (01h) to (FFh) given to the respective parts tables.
In addition, the link information is actually U-
It is indicated by a numerical value that is a byte position in TOC sector 0. That is, the parts table is designated as 304+ (link information) × 8 (byte). In addition, since a tune recorded in a pit form on a premastered disc or the like is not usually divided into parts, as shown in FIG. 11, all the link information in the P-TOC sector 0 is “(00h)”. There is.

That is, in the management table section in the U-TOC sector 0, one part table represents one part, and, for example, a music piece formed by connecting three parts is linked by link information. The position of the parts is managed by the three parts tables.

Each of the parts tables (01h) to (FFh) in the management table section of the U-TOC sector 0 has a table pointer (P-DF) in the corresponding table instruction data section.
A, P-EMPTY, P-FRA, P-TNO1 to P-TNO255)
The contents of the part are shown as follows.

The table pointer P-DFA is the mini disk 1
The upper defect area is shown, and one part table in which a track portion (= part) which becomes a defect area due to a scratch or the like is shown or a head part table in a plurality of part tables is designated. In other words, if there is a defective part, (01h) ~ (F
One of Fh) is recorded and the defective part is indicated by the start and end addresses in the corresponding parts table. If another defective part exists, another part table is designated as the link information in the part table, and the defective part is also shown in the part table. If there is no other defective part, the link information is, for example, "(00
h) ”and no link after that.

The table pointer P-EMPTY indicates the top parts table of one or a plurality of unused parts tables in the management table section. If an unused parts table exists, the table pointer P-EMPTY is used as a table pointer P-EMPTY. , (01h) to (FFh) is recorded.
If there are multiple unused part tables, the part tables specified by the table pointer P-EMPTY are used to sequentially specify the part tables by link information, and all the unused part tables are linked on the management table section. To be done.

The table pointer P-FRA is the mini disc 1
It shows the free area (including the erased area) where the above data can be written, and specifies the top parts table in one or more parts tables in which the track part (= parts) that is the free area is shown. ing. That is,
Table pointer P-FRA when free area exists
In (01h) ~ (FFh) is recorded,
In the corresponding parts table, parts that are free areas are indicated by start and end addresses. Also, if there are multiple such parts, that is, if there are multiple parts tables, the link information
Part tables with link information of "(00h)" are specified in sequence.

FIG. 13 schematically shows the management state of the parts which are the free area by using the parts table. This is when the parts (03h) (18h) (1Fh) (2Bh) (E3h) are set as the free area, this state corresponds to the corresponding table instruction data P-FRA.
Continuing on, the parts table (03h) (18h) (1Fh) (2Bh) (E3h)
Shows the state represented by the link. Note that the management form of the above-mentioned defective area and unused parts table is similar to this.

By the way, in the case of a magneto-optical disk in which audio data such as music is not recorded and there is no defect,
Parts table (01h) by table pointer P-FRA
Is specified, which indicates that the entire recordable user area of the disc is a free area. In this case, the remaining part tables (02h) to (FFh) are not used, so the part table (02h) is specified by the above table pointer P-EMPTY, and the part table (02h) The parts table (03h) is specified as the link information, and so on, and the parts table (FFh) is linked. In this case, the link information of the parts table (FFh) is set to "(00h)" indicating that there is no connection thereafter. At this time, the parts table (0
For 1h), the start address of the recordable user area is recorded as the start address, and the address immediately before the lead-out start address is recorded as the end address.

Table pointers P-TNO1 to P-TNO255 indicate music pieces recorded by the user on the magneto-optical disk 1. For example, in the table pointer P-TNO1, one or a plurality of pieces of data in which the first music piece is recorded are recorded. The parts table that indicates the temporally first part of the parts is specified. For example, when the track designated as the first song is recorded on the disc without dividing the tracks, that is, when it is recorded by one part, the recording area of the first song is the start and the start in the parts table indicated by the table pointer P-TNO1. It is recorded as the end address.

If, for example, the second music piece is discretely recorded in a plurality of parts on the disc,
Each part is designated in chronological order to indicate the recording position of the music. That is, the table pointer P-TNO2
From the parts table specified in, the other parts tables are sequentially specified by the link information according to the temporal order, and the parts table having the link information of "(00h)" is linked (similarly to FIG. 13 above. Form). In this way, for example, all the parts in which the data constituting the second song is recorded are sequentially designated and recorded, so that the data of the U-TOC sector 0 is used to reproduce the second song or the second song. When overwriting the area (1), the optical head 3 and the magnetic head 6 can be accessed to take out continuous music information from discrete parts, and recording can be performed efficiently using the recording area.

U-TOC Sector 1 FIG. 14 shows the format of the U-TOC sector 1, which is input mainly when the user gives a song title to a recorded song or a disc title. This is a data area for recording character information.

In this U-TOC sector 1, slot pointers P-TNA1 to P-TNA255 are prepared as character slot instruction data parts corresponding to the recorded music pieces. A character slot portion designated by the slot pointers P-TNA1 to P-TNA255 is prepared. 1 for character slot
Slots (01h) to (FFh) of 255 units are formed with a unit of 8 bytes, and character data is managed in a form similar to that of the U-TOC sector 0 described above.

Character information such as a disc title (disc name) and a song title (track name) is recorded in the slots (01h) to (FFh) in ASCII code. The 8-byte slot before the slot (01h) is a dedicated area for the disc name.

Then, for example, the character designated by the user corresponding to the first music piece is recorded in the slot designated by the slot pointer P-TNA1. Also, by linking the slots with link information,
Character input corresponding to one music can be supported even if it is larger than 7 bytes (7 characters). In this U-TOC sector 1, the slot pointer P-EMPTY manages an unused slot. That is, the above-mentioned U
-Unused slots are managed in the same way as the unused parts table management method using the table pointer P-EMPTY of TOC sector 0.

U-TOC sector 2 FIG. 15 shows the format of the U-TOC sector 2, which is mainly a data area for recording the recording date and time of the music recorded by the user.

In this U-TOC sector 2, slot pointers P-TRD1 to P-TRD255 are prepared as date / time slot instruction data portions corresponding to the recorded music pieces, and these slot pointers P-TRD1 to P-TRD255 are also provided. A date / time slot portion designated by is prepared. In the date / time slot portion, 255 units of slots (01h) to (FFh) are formed with 1 unit of 8 bytes, and date / time data is managed in a form similar to that of the U-TOC sector 0 described above.

In the slots (01h) to (FFh), the recording date and time of the music (track) is recorded in 6 bytes. The 6 bytes each contain 1 byte, and the numerical values corresponding to the year, month, day, hour, minute, and second are recorded. The remaining 2 bytes are a maker code and a model code, and code data indicating the manufacturer of the recording device that recorded the music and code data indicating the model of the recording device that recorded the music are recorded. The 8-byte slot before the slot (01h) is an area for recording date and time data for the disc.

For example, when a piece of music is recorded as the first piece of music on the disc, the recording date and time, the manufacturer code and the model code of the recording device are recorded in the slot designated by the slot pointer P-TRD1. The recording date and time data is automatically recorded by referring to the internal clock of the recording device.

In this U-TOC sector 1, the slot pointer P-EMPTY manages unused slots. For unused slots, link information is recorded instead of the model code, and each unused slot is managed by linking with the slot pointer P-EMPTY at the head.

U-TOC sector 4 Like the sector 1, the U-TOC sector 4 records the input character information when the user gives a recorded music title or a disc title. The area is a data area, and the format is almost the same as in FIG. However, in this sector, code data corresponding to Chinese characters and European characters are recorded. In addition to the data of sector 1 in FIG. 14, the attribute of the character code used as the character code is recorded at a predetermined byte position. . The management of the character information of the U-TOC sector 4 is performed by the slot pointers P-TNA1 to P-TNA255 and the slot pointers P-TNA1 to
Slot of 255 units (01 specified by P-TNA255
h) ~ (FFh).

4. Character Registration Corresponding to CD In the voice recording system of the present embodiment, the MD recording / reproducing unit 30 as described above can perform recording on the mini disc 1 and, in correspondence with the recorded track, Character information can be recorded in the U-TOC sector 1 or sector 4.

In this embodiment, the CD by the CD reproducing section 40 is used.
When the reproduced sound is supplied to the MD recording / reproducing unit 30 and dubbed to the mini disc 1 (dubbing mode), the received sound of the radio tuner unit 50 is supplied to the MD recording / reproducing unit 30 and recorded on the mini disc 1. At this time (in the air check mode), character input to the mini disc 1 is automatically performed.

In order to execute this operation, the user first sets the character information in SR corresponding to each CD 41 or broadcasting station in advance.
It is necessary to register with AM61. Where C
A process for registering a character corresponding to D41 will be described with reference to FIGS.

When the user registers character information for each CD, the S-RAM 61 stores, for example, FIG.
The registration data is stored in such a form. When a disc name and a track name of each track are registered for a certain disc, a disc identification code D _{ID1 for} identifying the disc is recorded. Correspondingly, the disc name DN ₁ , the track name TN ₁ ...
TN _{1 (n-1)} is stored. This is the case where the number of tracks on the CD is (n-1).

Here, the disc identification code D _ID1 is a code generated using the TOC information of the CD, as is known as a custom file, for example. For example, a code is generated by combining the total playing time of the CD, the total number of tracks, and the playing time of track 1. The codes generated in this way can hardly be the same on different CDs, and thus can be used as a disc identification code.

The disc name DN ₁ and the track names TN _{1 to} TN _{1 (n-1)} are character information, and the disc name DN ₁ is, for example, an album title, track names TN _{1 to} TN _{1 (n-1). )} Is stored when the user inputs the song name of each track (song).

Similarly, the disc identification codes are D _ID2 , D
For the CD 41 having _ID3 , D _ID4, ..., the user inputs the disc name and the track name and registers them as shown in FIG. Figure 3 shows the disc identification code D _ID2
CD41 has 2 tracks and disc identification code D
The CD 41 of _ID3 has one track and the CD 41 of the disc identification code D _ID4 has n tracks.

In order to perform such registration, the input unit 63
In response to the user's registration operation from the controller 60
Performs the processing of FIG. When performing character registration on a certain CD, the user first loads the CD into the CD reproducing section 40 to enter the character registration mode. When the controller 60 is set to the character registration mode, from step F101
In step F102, it is determined whether or not the CD 41 is correctly loaded in the CD reproducing section 40. That is, it is determined whether or not the disc is present and whether the TOC can be read.

If the TOC can be read, the T
The above-mentioned disc identification code is generated from the OC information (F
103). Then, the S-RAM 61 is searched to determine whether or not the disc identification code is already registered in the S-RAM 61 (F104).

If it is not registered, it is the first registration operation for the CD 41, and therefore the process proceeds to step F105, and the initial input screen is displayed on the display unit 64. If it is already registered, for example, the user may want to change the registered character information. At this time, the process proceeds to step F106, the character information registered corresponding to the CD 41 is read from the S-RAM 61 and displayed on the display unit 64.

In response to these displays, the user inputs a new character or a character to change the registered character. Each time a character is input, the controller 60 proceeds from step F107 to step F108 to display the display unit 6
Display or update the input character on 4. The character information to be input includes a disc name and a plurality of track names as shown in FIG. 3, so that the user can sequentially specify these and perform new input or update.

When the user finishes inputting characters and performs an enter operation, the process proceeds from step F109 to F110 to perform confirmation display. At this time, for example, the input / updated characters may be sequentially displayed. On the other hand, the user performs the enter operation again, the correction operation, or the cancel operation (F111).

When the character input may be registered, the user performs an enter operation. Then, in step F112, the input or changed character information is registered in the S-RAM 61 in the form as shown in FIG. When the correction operation is performed, the process returns to step F107 and the input can be made again. Further, when the cancel operation is performed, the processing is finished as it is. That is, the input operation up to that point is invalid.

By performing such a process for each CD, the character information for each CD is stored in the S-RAM 61 as shown in FIG.

5. Character Registration Corresponding to Broadcasting Station Next, a process for performing character registration corresponding to a broadcasting station will be described with reference to FIGS. 5, 6, 7 and 8.

When the user registers the character information for each broadcasting station, the registration data is stored in the S-RAM 61 in the form as shown in FIG. 5, for example. That is, when a broadcasting station name is input for a certain broadcasting station whose frequency is preset, character information is registered as shown in FIG. 5 in correspondence with the preset number and the frequency. The user will input a character by designating a preset number.

In order to perform such registration, the input unit 63
In response to the user's registration operation from the controller 60
Performs the processing of FIG. When performing character registration for a certain broadcasting station, the user first receives the broadcasting station. That is, the preset number is selected. Then, the controller 60 proceeds from step F201 to step F202, and the ROM
62 or the preset frequency data stored in another area of the S-RAM 61, and the radio tuner unit 5
0 to control the reception frequency and execute reception / demodulation. When the user performs an operation to enter the character registration mode in this state, the controller 60 searches the S-RAM 61 and determines whether or not it is already registered in the character information corresponding to the preset number (or frequency). Yes (F204).

If it is not registered, it is the first registration operation for the broadcasting station, and therefore the process proceeds to step F205, and the initial input screen is displayed on the display unit 64. If it is already registered, for example, the user may want to change the registered character information. At this time, the process proceeds to step F206, the character information registered corresponding to the broadcasting station is read from the S-RAM 61 and displayed on the display unit 64.

In response to these displays, the user inputs new characters or characters to change registered characters. Each time a character is input, the controller 60 proceeds from step F207 to step F208 to display the display unit 6
Display or update the input character on 4. When the user finishes inputting characters and performs an enter operation, step F2
Proceed from 09 to F210 to display a confirmation. At this time, for example, the input / updated character is displayed.

On the other hand, the user performs the enter operation again, the correction operation, or the cancel operation (F211). When the user can register the character input, the user performs the enter operation. Then, step F212
In, the input or changed character information is registered in the S-RAM 61 in the form as shown in FIG. When the correction operation is performed, the process returns to step F207 and the input can be made again. Further, when the cancel operation is performed, the processing is finished as it is. That is, the input operation up to that point is invalid.

By performing such processing for each broadcasting station, the character information for each broadcasting station is stored in the S-RAM 61 as shown in FIG.

By the way, a broadcasting station name can be registered more easily by using a function known as auto area call. The auto area call is to identify a current area by detecting receivable frequencies in a certain area, and display a broadcasting station name during a receiving operation in the area.

In order to execute the auto area call, R
Data as shown in FIG. 7 is stored in the OM 62. The data in FIG. 7 is for each region (regions A, B, C ...)
Is the data stored in association with the frequencies and the names of the broadcasting stations that can be received. For example, if three broadcasting stations can receive in the area A, the frequency f ₁ and the broadcasting station name BC _A1 are stored in association with each other as shown in the figure, and similarly, the frequency f ₂ and the broadcasting station name BC _A2 , the frequency f ₃ are stored. And station name B
It is stored in association with C _A3 . f _{1 to} f ₃ are numerical value data representing frequencies, and BC _{A1 to} BC _A3 are character data representing broadcast station names as shown in FIG.

In the other areas B, C and D, similarly, the receivable frequencies and the broadcasting stations are stored in correspondence with each other. Now, suppose that the user is in region A, such as traveling, and wants to listen to the radio, but does not know the broadcasting station or frequency in that region. At this time, when the auto area call function is executed, the controller 60 scans the reception frequency and determines the frequency that can be received. Then, it is assumed that the frequencies that can be received are f ₁ , f ₂ , and f ₃ . Here, the controller 60 searches the ROM 62 for the data shown in FIG. 7 and determines the area where f ₁ , f ₂ , and f ₃ can be received.
That is, the area where f ₁ , f ₂ , and f ₃ can be received is only the area A, and it can be specified that the area is A.

The frequencies f ₁ , f ₂ and f ₃ are made to correspond to the preset numbers 1, 2 and 3. When the user operates the preset number 2, the controller 60 controls the radio tuner section 50 to perform reception at the frequency f ₂ . Also, the broadcast station name BC _A2 stored corresponding to the frequency f ₂ is read out and displayed on the display unit 6.
Display on 4. This allows the user to easily listen to the radio even in a land they do not know and to know which broadcast station the broadcast station is.

When such an automatic area call function is installed, the controller performs character registration by the processing of FIG. When the user selects the preset number for receiving the broadcasting station when the auto area call function is enabled, the controller 60 will step
From F301 to F302, frequency scan is performed. That is, as described above, the area is first discriminated.
Then, compare the frequency that could be received with the data in FIG. 7,
The region is specified and the frequency of the region is assigned to each preset number (F303, F304).

Then, the frequency data assigned to the preset number selected in step F301 is read out,
Supply to the radio tuner 50 to control the reception frequency,
Perform reception / demodulation. At this time, the broadcast station name data stored correspondingly is also read and displayed on the display unit 64 (F305). In this state, the user can confirm the broadcasting station name. When the user performs an operation to enter the character registration mode, the controller 60 registers the broadcasting station name in the S-RAM 61 as shown in FIG. 5 in association with the frequency (F307). By such processing, the user can register the broadcast station name without having to enter the broadcast station name.

6. Operation during dubbing recording As described above, the character information is S for CD41 and broadcasting stations.
-By registering in the RAM 61, the voice recording system of the present embodiment does not require character input during dubbing or air check. First, the operation during dubbing will be described with reference to FIG.

The user inserts the CD 41 into the CD reproducing section 40,
In addition, the mini disk 1 is loaded in the MD recording / reproducing section 30,
CD41 by recording operation in dubbing mode
To a mini disc 1 can be recorded. By setting the dubbing mode, the controller 60
Connect switch 65 to the T _CD terminal, and switch 66
To turn on.

When the user operates the dubbing mode, the controller 60 first determines the CD 41 loaded in the CD reproducing section 40. That is, T of CD41
The disc identification code is extracted from the OC information (F401). Since the TOC information of the CD 41 is usually given when the CD 41 is loaded, the disc identification code can be extracted at that time. Already C when the dubbing mode is set
If the disc identification code of D41 is extracted,
The process of this step F401 is unnecessary.

Here, when the user performs a recording operation,
The process proceeds from step F402 to F403, and the variable n is first set to 0. Then, the variable n is incremented (F40
4), reproduction from the track of the n-th reproduction step in the CD reproducing section 40, and recording of the reproduced signal on the mini disk 1 in the MD recording / reproducing section 30. It should be noted that the track in the n-th reproducing step does not always match the track number. For example, when dubbing by playing the CD 41 in a normal song order, n = track number, and the tracks are played from track 1. However, when dubbing is performed by designating the song order in program playback, n is It becomes the value corresponding to the program step number.

Next, as the processing of step F406, the registration data for the CD 41 is searched from the disc identification code, and the registration character information corresponding to the reproduction track is S.
-Reading from RAM 61, M of MD recording / reproducing unit 30
Transfer to the D controller 11. MD controller 11
Then, this is used as the track name corresponding to the track of the n-th reproduction step, and the buffer RAM 1
U-TOC data in 3 is updated. That is, U-TOC
It is stored as the track name corresponding to the track number of the nth reproduction step in sector 1.

In the MD recording / reproducing section 30,
The track number of the n-th reproduction step is n. In other words, even if n does not correspond to the track number in the CD reproducing unit 40 during program reproduction or the like, track numbers are added in the order of input on the MD recording / reproducing unit 30 side. Will be the track number.

When the CD reproducing section 40 finishes reproducing the track in the n-th reproducing step, the controller 60
It is confirmed whether or not the next reproduction step exists, and if it exists, the process returns to step F404 and the variable n is incremented.
Then, similarly, in steps F404 and F405, the CD reproducing unit 40
Playback of the nth playback step and MD recording /
The reproducing section 30 is caused to record the track having the track number n, and the character information corresponding to the track is recorded in SR.
It is read from the AM 61 and transferred to the MD controller 11.

In the normal reproducing operation in the CD reproducing section 40, it is determined that there is no next track in step F407 at the time when the tracks from the track 1 to the last track are reproduced.
When the CD reproducing section 40 performs the program reproduction, it is determined that there is no next track when the reproduction of the track, which is the final step in the program step, is completed.

When it is determined in step F407 that there is no next track, the controller 60 determines that the MD recording / reproducing unit 30
Stop the recording operation of (F408). At this point, the buffer RAM 13 of the MD recording / reproducing unit 30 stores the recorded addresses of the tracks on the mini disk 1 and the track names as U-TOC information. Then, the MD controller 11 writes the updated U-TOC data stored in the buffer RAM 13 to the mini disk 1 at a predetermined timing (F409).

By the above processing, during dubbing operation,
Even if the music title is not input, the track name will be recorded on the mini disc 1 side. Although the disc name is not mentioned in this process, the U-TOC may be rewritten by transferring the character information serving as the disc name to the MD controller 11 at the start or end of dubbing. . Alternatively, for example, the disc name may be transferred only when the CD reproducing section 40 performs normal reproduction to copy all the songs on the CD 41 to the mini disc 1.

7. Operation during air check recording Next, the operation during air check will be described with reference to FIG.
By performing a recording operation in the air check mode, the user can perform air check recording of the received voice on the mini disc 1. In the air check mode, the controller 60 connects the switch 65 to the T _TU terminal and turns on the switch 66.

When the user selects the preset number in the air check mode, the controller 60 first causes the radio tuner section 50 to perform the receiving operation at the frequency stored in the preset number (F50).
1, F502).

Here, when the user performs a recording operation,
The process advances from step F503 to step F504 to start recording on the mini disc 1 in the MD recording / reproducing unit 30. In other words, air check recording is started. In the case of air check, the sound from the start to the end of recording is recorded as one track.

Here, the controller 60 is the S-RAM 6
The frequency and broadcasting station name data registered corresponding to the preset number is read from the data registered in FIG. 1 as shown in FIG. 5 and transferred to the MD controller 11 of the MD recording / reproducing unit 30. Further, the current date and time information is obtained from the internal clock 60a of the controller 60 and transferred to the MD controller 11 (F505).

When the user performs a stop operation at a certain point, the controller 60 stops the recording operation of the MD recording / reproducing section 30 (F506, F507). At this point, MD recording /
In the buffer RAM 13 of the reproducing unit 30, the address of the recorded track on the mini disk 1 is written on the U-TOC sector 0 data, and the track name and the U-TOC are written on the U-TOC sector 1 data. The date and time information is stored on the sector 2. The track name is a broadcasting station name and / or frequency. Then, the MD controller 11 writes the updated U-TOC data stored in the buffer RAM 13 to the mini disk 1 at a predetermined timing (F508).

With the above processing, the broadcasting station name is recorded as the track name on the side of the mini disc 1 without inputting the broadcasting station name during the air check operation.
Also, the recording date and time will be recorded. Although the recording date and time is not described as the processing during dubbing as described above, it goes without saying that the recording date and time may be automatically recorded during dubbing.

As described above, since the dubbing recording and the air check recording according to the present embodiment are performed, the user does not have to bother to input a song name or a broadcasting station name to the mini disc 1 at the time of dubbing or air checking. Without
The complicated input operation will be eliminated. In particular, some C
In the case of dubbing D onto a plurality of mini-discs 1 or the like, the extremely troublesome operation of inputting characters to each mini-disc is not necessary, and the operation of this embodiment is very convenient. Of course, the same is true for the air check.

As a modification of the present invention, an S-RAM is used.
It is conceivable that registration to 61 etc. can be performed independently at the time of dubbing or air check. That is, the character information can be registered in the S-RAM 61 or other memory means at the time of dubbing, and can be transferred to the MD controller 11 of the MD recording / reproducing unit 30 at the end of the dubbing. Is.

In the above embodiment, the dubbing source is C
Although it is referred to as D, this may be used as another recording medium such as a mini disk, DAT, or analog tape. Further, the air check source may be other broadcast such as television broadcast instead of radio.

[0123]

As described above, in the audio recording system of the present invention, when the audio signal received by the broadcast receiving means is supplied to the recording means and recorded on the recording medium, the broadcasting station receiving from the storage means. Is read out and supplied to the recording means, and the character information is recorded on the recording medium in correspondence with the voice data to be recorded. Also,
When the audio reproduction signal reproduced from the recording medium by the reproducing means is supplied to the recording means and recorded on the recording medium, the character information corresponding to the recording medium to be reproduced and //
Alternatively, the character information corresponding to the audio data unit to be reproduced on the recording medium is read out and supplied to the recording means, and the character information is recorded on the recording medium corresponding to the audio data to be recorded. For this reason, it is not necessary to input character information to the recording medium on the recording side at the time of air check or dubbing, and it is possible to eliminate the troublesome character input operation by the user.

Further, the character information is registered by being fixed in the storage means by being fixed to the broadcasting station or the recording medium which is the signal source of the audio signal supplied to the recording means. It is possible to eliminate the need for inputting characters.

Further, the character information is input by characterizing the broadcasting station or the recording medium which is the signal source of the audio signal supplied to the recording means, so that the user corresponds to the broadcasting station or the recording medium. There is an effect that it is possible to freely register text information.
