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 and 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. 8 shows one sector (sector 0) of P-TOC information which is repeatedly recorded in the area for P-TOC (for example, the ROM area on the innermost 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 and recording level, the song number of the first song recorded (First TNO), the song number of the last song recorded (Last TNO), the lead-out start address LO _A , the 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.

Then, 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 following the correspondence table instruction data portion, corresponding to the table pointers (P-TNO1 to P-TNO255) in the correspondence table instruction data portion, (01h) to (FF).
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 includes 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 song, 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 U-TOC sector 0, sector 1, and sector 2 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. 9 shows the format of the U-TOC sector 0, which is mainly a data area in which management information about music recorded by the user and free areas in which new music can be recorded is recorded. It For example, when trying to record a certain music on the mini disk 1, M
The D controller 11 searches for a free area on the disc from the U-TOC sector 0 and records the audio data there. Further, at the time of reproduction, the area in which the music to be reproduced is recorded is discriminated from the U-TOC sector 0, and that area is accessed for reproduction operation.

In the U-TOC sector 0 shown in FIG. 9, P
Like the TOC, a header is provided first, followed by a manufacturer code, model code, song number of the first song (First TNO), and 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 for the user to make a recording and to identify the recorded music area or free area by associating it 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 the PT of FIG. 8 above.
Similar to OC 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 disturbed 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, link information is provided, and the part tables can be linked by designating the part tables to be linked by the numbers (01h) to (FFh) given to the respective part 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. 8, 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 a mini disc 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 there is an unused parts table, the table pointer P-EMPTY is used as the 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 disk 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. 10 schematically shows the management state of the parts which are the free area by 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.

The 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 data pieces of the first music piece 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 in which the link information is “(00h)” is linked (same as above, FIG. 10). 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. 11 shows the format of the U-TOC sector 1. This is mainly input when the user gives a song title or disc title to the recorded music. This is a data area for recording character information.

In the 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 music 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, in the slot designated by the slot pointer P-TNA1, the character input by the user corresponding to the first music piece is recorded. 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. 12 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 parts corresponding to the respective 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 and the manufacturer code and 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 the unused slot. 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 The U-TOC sector 4 records the input character information when the user gives a song title or a disc title to the recorded song, like the sector 1. 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, and in addition to the data of sector 1 in FIG. 11, 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

4. Timer Setting Operation In the audio recording system of the present embodiment, the MD recording / reproducing unit 30 as described above can perform recording on the mini disc 1 and also corresponds to the recorded track and the like, and the U-TOC. Character information can be recorded in sector 1 and sector 4.

When the user sets the timer, this recording operation can be automatically executed from the set time. Further, in the present embodiment, when the recording operation based on the timer setting supplies the externally input voice or the reception voice of the radio tuner unit 50 to the MD recording / reproducing unit 30 to record on the mini disc 1, the characters for the mini disc 1 are recorded. The input is done automatically.

In order to execute this operation, it is necessary that the user first sets the timer in advance, at this time, inputs character information according to the recorded contents and registers it in the S-RAM 61. The timer setting operation will be described with reference to FIGS.

When the user performs an operation for setting the timer, the S-RAM 61 stores the timer set information in the form as shown in FIG. 3, for example. The timer set information is a recording start time (on time), a recording end time (off time), and a function. The function is to select a recording source, and in the case of the configuration of FIG. 1, it is to specify the radio tuner section 50 or the external input terminal 40.

When the radio tuner section 50 is set, the switch 65 is connected to the T _TU terminal during recording,
When the external input terminal 40 is set, the switch 65 is connected to the T _IN terminal during recording. Furthermore, when the radio tuner unit 50 is set, the reception frequency,
That is, the broadcasting station is also set. For example, the frequency data is stored, or the preset number of the broadcasting station is stored.

When the timer set information is input, the user can input character information such as program content. As a result, the character information is stored corresponding to each timer set information as shown in FIG.

Since the timer is set in this manner, the controller 60 will perform the processing shown in FIG. 4 in accordance with the user's input operation from the input section 63. When the timer setting mode is set, the process of the controller 60 is step F1.
The process proceeds from 01 to F102, and it is determined whether the recording timer setting or the reproduction timer setting is set. The reproduction timer setting is, for example, a setting for the user to listen to the radio or reproduce the mini disc 1 from a predetermined time, and in that case, the process proceeds to step F103. Since the setting of the reproduction timer is not directly related to the present invention, detailed description will be omitted.

If the recording timer is set, the process proceeds to step F104. First, the function setting process is performed.
Here, the controller 60 performs a display on the display unit 64 to allow the user to select the source of the audio signal. On the other hand, the user may use external input or the radio tuner unit 50.
Input to select or. Radio tuner section 50
If is selected, the controller 60 causes the display unit 64 to display a selection of broadcasting stations. The user accordingly selects, for example, a preset number or inputs a frequency. Then, the controller 60 takes in the input function data.

When this function setting is completed, the on-time setting process is performed in step F105. Here, the controller 60 makes a display for inputting the recording start time. The user starts the recording for this,
Enter the day, hour, and minute. The controller 60 takes in the input on-time data.

Next, in step F106, off-time setting processing is performed. Here, the controller 60 performs a display for inputting the recording end time. The user inputs the month, day, hour, and minute to end the recording. The controller 60 takes in the input off time data.

As described above, the timer set information has been input. In step F107, the controller 60 further
A display prompting the input of character information is displayed on the display unit 64. The user can enter characters accordingly. For example, the title of a program to be recorded by a timer, the title of a song to be broadcast, etc. can be input. When the character information is input, the controller 60 takes in the input character information.

Next, the controller 60 performs input content confirmation processing (F108). For example, the input function data, on-time data, off-time data, and character information are displayed on the display unit 64 to prompt the user for confirmation. The user can perform an enter operation, a correction operation, and a cancel operation for this.

When the user performs the enter operation, the process proceeds from step F109 to step F110, and the inputted timer set information and character information are stored in the S-RAM 61 in the form as shown in FIG.
Will be registered in. When the correction operation is performed, the process returns to step F104 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,
As shown in FIG. 3, the character information is stored in the S-RAM 61 corresponding to each timer set information. If you set the external input as a function,
Needless to say, the user also needs to set the timer operation on the device side connected to the external input terminal 40. However, this is not necessary if the system is configured so that the controller 60 can control the external device.

By the way, the controller 60 can automatically set the character information without the user inputting it. For example, the broadcast station name is stored in advance corresponding to the preset frequency, or the character information such as the broadcast station name can be set by using a function known as auto area call.

As the preset data, the preset number and the frequency are stored in the S-RAM 61 or the ROM 62 in correspondence with each other as shown in FIG. Registered in the ROM 62 is preset data preset by the manufacturer, and registered in the S-RAM 61 is preset data set by the user himself.

Here, as the preset data, character information to be a broadcasting station name is further stored as shown in FIG. The manufacturer stores in advance the preset data registered in the ROM 62. Also S
-Regarding the preset data registered in the RAM 61, the user can input the broadcasting station name and the like at the time of preset registration.

Since the broadcasting station name is stored corresponding to the preset data as shown in FIG. 5, the user does not have to bother to input the character information in the process of step F107 of FIG. . For example, when preset number 1 is set as function data,
If the character input is not executed in step F107, the character information "FM Tokyo" stored corresponding to the preset number 1 can be used as the character information corresponding to the timer set information.

Further, by using a function known as auto area call, the broadcasting station name can be converted into character information corresponding to the timer set information. 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. 6 is stored in the OM 62. The data in FIG. 6 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.

Similarly, for the other areas B, C and D, the receivable frequencies and the broadcasting stations are stored in association 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. 6 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.

Then, the frequencies of 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. As a result, the user can easily understand the radio device and the broadcasting station that the broadcasting station belongs to even in a land that the user does not know.

When such an automatic area call function is installed, the user does not need to input character information in the process of step F107 when the timer setting process of FIG. 4 is executed. . For example, when preset number 1 is set as function data,
If character input is not performed in step F107, the character information stored corresponding to the preset number 1 can be used as the character information corresponding to the timer set information. That is, the controller 60 confirms the current area by performing the automatic area call operation when the timer is set or when the timer recording is performed, and determines the frequency to be the preset number 1 from the data of FIG. In the area B, for example, the broadcasting station name BC _B1 stored in correspondence with the preset number 1 can be used as the character information corresponding to the timer set information.

Note that the character information automatically set in this way corresponds to the timer set information as shown in FIG.
It may be stored in the RAM 61, or may be generated in association with timer set information (preset number, etc.) when actually transferring character information to the MD recording / reproducing unit 30 side as described later. Good.

5. Timer recording operation By setting the timer as described above, in the voice recording system of the present embodiment, the timer recording operation is performed based on the timer setting, and at the same time, the character information or the timer set information input when the timer is set. The character information such as the name of the broadcasting station generated in correspondence with
The above can be recorded corresponding to the recording track.
This timer recording operation will be described with reference to FIG.

After setting the timer, the user turns off the main power supply and puts the system in the standby state, thereby entering the timer recording standby state (F201, F202). In this state, the controller 60 confirms the on-time data of the timer set information as shown in FIG. 3 and the current time by the clock 60a (F203). If the current time matches the on-time data, turn on the main power supply of the system. (F204). Then, the connection of the switch 65 is executed according to the function data, and the radio tuner unit 50 is connected with the function data.
If is specified, the reception frequency of the radio tuner section 50 is controlled by the frequency set as the function data or the preset number. Further, the switch 66 is turned on, and control for starting recording on the mini disk 1 in the MD recording / reproducing unit 30 is performed (F205).

By this recording operation, the radio tuner unit 5
0 or an audio signal supplied from the external input terminal 40 is recorded on the mini disk 1. During the recording operation, the controller 60 confirms the off time data of the timer set information and the current time by the clock 60a (F206),
When the current time matches the off-time data, the recording on the mini disc 1 by the MD recording / reproducing unit 30 is first ended (F207).

At this point, in the MD recording / reproducing section 30,
The buffer RA is set so that the audio data recorded on the mini disk 1 from the on time to the off time becomes one track.
The U-TOC information read on M13 is updated. Here, the controller 60 reads the character information stored in the S-RAM 61 corresponding to the operated timer set information and transfers it to the MD controller 11.

The character information which is automatically set in correspondence with the timer set information (preset number, etc.) may be generated at the time of step F208, and it should be transferred to the MD controller 11. become.

In response to the transfer of the character information, the MD controller 11 writes the character information transferred as the character corresponding to the recorded track in the U-TOC sector 1 or sector 4 on the buffer RAM 13. The recording date and time is written in the U-TOC sector 2. The MD controller 11 may take in the current time of the clock 60a of the controller 60 as the recording date and time at the start of recording. Alternatively, the controller 60 may transfer the on-time data at the same time as the transfer of the character information in step F208, and the MD controller 11 may write this on the U-TOC sector 2 as the recording date and time.

The MD controller 11 updates the U stored in the buffer RAM 13 at a predetermined timing.
-TOC data will be written to the mini disk 1.
(F210). Then, when the writing of the U-TOC data to the mini disk 1 is completed, the controller 60 turns off the main power source and returns to the standby state.

By the above processing, regarding timer recording,
Even if the user does not input the character information indicating the broadcast contents after recording, it is automatically recorded on the mini disc 1 side. For this reason, not only is it unnecessary to input complicated characters after recording, but character information is displayed when the timer-recorded content is played back for confirmation. You don't have to worry about it.

As the automatically set character information, not only the broadcasting station name but also characters indicating the reception status at the time of timer recording may be generated and recorded on the mini disk 1. In addition, for example, when dubbing the CD playback sound to the mini disc 1 by an external input, if the disc name and the track name corresponding to each track are input when the timer is set,
When the dubbing is completed, the disc name and the track name corresponding to each track are automatically recorded on the mini disc 1 side.

Further, in the case of timer recording from a source that also receives character data, such as FM multiplex broadcasting, a predetermined number of characters is extracted from the character information sent in this way and made to correspond to the recorded track. You may make it record it.

Further, as a process after timer recording, a list of the character information recorded for the recorded tracks is displayed on the display unit 64 so that the user can edit the character information and the recorded voice tracks. It will be convenient.

[0109]

As described above, in the voice recording system of the present invention, when the timer is set, the timer set information and the character information are input and stored correspondingly, and the timer recording operation based on the timer set information is handled. The recorded character information is recorded as character information corresponding to the track recorded on the recording medium. Therefore, there is an effect that the user does not have to perform a complicated operation of inputting characters while checking the recorded content after timer recording.

Further, according to the present invention, the character information is automatically generated based on the timer set information, and the character information corresponds to the track information recorded on the recording medium during the timer recording operation.
