[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus, for example, when recording an audio signal reproduced by a compact disk player by a mini disk apparatus, a reproducing position by a bar graph display arranged side by side,
By displaying the recording position and the like, the time information necessary for grasping the recording / reproducing situation is visually and sensibly displayed, and the recording / reproducing situation can be intuitively grasped through this display.

[0002]

2. Description of the Related Art Conventionally, in compact discs and mini discs, various management information is recorded in a lead-in area formed in the innermost circumference, and the recording start position, the recording end position and the entire recording position of each music are recorded by this management information. It is designed to be able to detect the playing time of the. On a compact disc, position information is recorded along with the audio signal,
Further, in a mini disc, position information is recorded by a pre-groove that forms a guide groove for a laser beam.

By making effective use of this management information and position information, the compact disc player can play the entire playing time, the reproduction time accumulated up to the present time (hereinafter referred to as reproduction accumulated time), and the remaining reproduction time (hereinafter referred to as remaining reproduction time). (Referred to as) etc. are formed. Also in the mini disk device, similarly, it is formed so as to display the recording time (hereinafter referred to as the accumulated recording time) and the remaining recordable time (hereinafter referred to as the remaining recording time) in which the recorded area is converted into time information,
This improves the usability for the user.

Here, these time displays are formed, for example, by displaying these time information by character information on a liquid crystal display panel or the like, and the display of the reproduction accumulated time is, for example, 12 from the beginning of the compact disc. When the position of 34 minutes is reproduced, the character "12:34" is displayed on the liquid crystal display panel or the like. As a result, the compact disc player and the mini disc device allow the user to easily and surely check the playing time and the like.

[0005]

By the way, in this type of audio device, the compact disc player and the mini disc device are integrally held so that the audio signal reproduced by the compact disc player can be recorded by the mini disc device. There is something (so-called dubbing).

In this dubbing, since the total playing time of the compact disc and the recordable time of the mini disc do not necessarily match, further recording may be performed on the mini disc following the already recorded performance. Depending on what is possible, at least the accumulated playback time,
If it is possible to confirm the remaining playback time, the total recording time, and the remaining recording time at the same time, it is possible to judge the dubbing situation, which is considered convenient.

In this case, as shown in FIG. 11, a method of displaying these four kinds of time information side by side can be considered. That is, the time information of the compact disc is "C
Characters "D" are displayed, and adjacent to this display, the accumulated reproduction time (displayed as "12:34") and the remaining reproduction time ("R"
MAININ 30:10 ”is displayed).
Further, it is indicated by the character display of "MD" that the time information of the mini disk is formed, and adjacent to this display, the accumulated recording time (displayed as "12:34") and the remaining recording time ("RE
MAIN 47:26 ”is displayed).

However, if the time information is simply displayed side by side in this way, it is difficult to immediately grasp the progress of dubbing. In this case, if this kind of time information can be visually and sensibly grasped, the progress of dubbing can be intuitively grasped.

The present invention has been made in consideration of the above points, and is intended to propose a recording / reproducing apparatus capable of visually and sensibly grasping time information necessary for grasping a recording / reproducing situation. is there.

[0010]

In order to solve such a problem, according to the present invention, a recording / reproducing apparatus for reproducing an information signal recorded on a first disk-shaped recording medium and recording it on a second disk-shaped recording medium. Apply to. In this recording / reproducing apparatus, based on the position information recorded on the first disc-shaped recording medium, reproduction position detecting means for detecting the reproduction position and generating reproduction position information, and recording on the second disc-shaped recording medium. A recording position detecting unit that detects a recording position based on the generated position information and generates the recording position information, and a prescribed display unit are provided. At this time, this display means
Based on the reproduction position information and the recording position information, first and second bar graph-shaped displays corresponding to the first and second disk-shaped recording media are formed side by side, and the first and second bar graph-shaped displays are formed. The playback position and recording position are displayed.

At this time, the above-mentioned display means partially blinks the bar-graph-shaped display to display the recording position and the reproduction position, and the first and second bar-graph-shaped displays indicate the first and second positions. And the data amount of the information signal recorded on the second disk-shaped recording medium is displayed.

Alternatively, the display means may be arranged such that the maximum length of the first bar-graph-shaped display corresponds to the reproducible data amount of the first disc-shaped recording medium. 1
Of the second disk-shaped recording medium and the maximum length of the second bar-shaped display is equal to the length of the first bar-shaped display. The second bar graph-like display is formed so as to correspond to the recordable data amount.

Instead of this, the above-mentioned display means is the first
The second bar-graph display is formed so that the maximum length of the bar-graph display corresponds to the recordable data amount of the second disk-shaped recording medium, and the first bar-graph display is formed. , The data amount of the first disk-shaped recording medium assigned to the unit length is substantially equal to the data amount of the second disk-shaped recording medium assigned to the unit length in the second bar graph display. So that the first bar graph-like display is formed.

Further, in place of these configurations, the present invention is applied to a recording / reproducing apparatus for selectively reproducing the information signal recorded on the first disk-shaped recording medium and recording it on the second disk-shaped recording medium. Here, the first and second disc-shaped recording media divide the information recording surface into a management area for recording management information and an information signal recording area for recording the information signal, and the information signal recording area is defined by the management information. It is assumed that the information signal recorded in 1 is formed so that it can be managed. In this recording / reproducing apparatus, reproduction side management information detecting means for reproducing the management information of the first disk-shaped recording medium and detecting reproduction side management information, and reproducing and recording the management information of the second disk-shaped recording medium. A recording side management information detecting means for detecting the side management information and a prescribed display means are provided. Here, the display means forms first and second bar graph-shaped displays corresponding to the first and second disk-shaped recording media side by side, respectively, and based on the reproduction side management information and the recording side management information. , The data amounts of the information signals respectively recorded on the first and second disk-shaped recording media are displayed by the lengths of these first and second bar graph-shaped displays, and based on the reproduction side management information described above. , An information signal to be selectively reproduced is displayed in a blinking manner on the first bar graph display, and an order in which the information signal to be selectively reproduced is recorded on the first disk-shaped recording medium is displayed. On the second bar graph display, the area corresponding to the data amount of the previous blink display is blinked.

By these means, the display means forms the first and second bar graph-like displays corresponding to the first and second disc-shaped recording media side by side, based on the reproduction position information and the recording position information. However, if the reproduction position and the recording position are displayed by the first and second bar graph-like displays, the recording position and the reproduction position can be visually and sensibly grasped, and the display position of the recording and reproduction position can be grasped. The accumulated reproduction time, accumulated recording time, remaining reproduction time, and remaining recording time can be grasped from the lengths before and after.

Specifically, the above-mentioned display means partially blinks the bar graph-shaped display to display the recording position and the reproduction position, and the first and second bar graph-shaped display lengths indicate the first and second bar graph-shaped displays. If the data amount of the information signal recorded on the first and second disc-shaped recording media is displayed, the accumulated reproduction time is calculated by the length of the bar-graph display in addition to the recording position and the reproducing position.
The cumulative recording time can be visually grasped.

Alternatively, the first bar-graph-shaped display is so arranged that the maximum length of the first bar-graph-shaped display corresponds to the reproducible data amount of the first disk-shaped recording medium. And the recordable data of the second disk-shaped recording medium is such that the maximum length of the second bar-graph-shaped display is equal to the length of the first bar-graph-shaped display. If the second bar graph-like display is formed so as to correspond to the amount, the remaining playback time is intuitively set when the recording / playback process is performed between the disk-shaped recording media having different data amounts.
It is possible to grasp the remaining recording time.

Alternatively, the second bar graph display is formed so that the maximum length of the first bar graph display corresponds to the recordable data amount of the second disk recording medium. Then, the data amount of the first disk-shaped recording medium assigned to the unit length in the first bar graph-like display is assigned to the second length assigned to the unit length in the second bar-graph-like display. If the first bar graph-shaped display is formed so as to be approximately equal to the data amount of the disc-shaped recording medium, the reproduction is intuitively performed even when the capacities of the first and second disc-shaped recording media are significantly different. It is possible to grasp the remaining time, the remaining recording time, etc.

Further, instead of these means, first and second bar graph-shaped displays corresponding to the first and second disk recording media are formed side by side, and these first and second bar graph-shaped displays are formed. The data length of the information signal recorded on each of the first and second disc-shaped recording media is displayed according to the length of the display, and is selected on the first bar-graph display based on the reproduction side management information. Of the information signal to be selectively reproduced by blinking the data amount of the information signal to be selectively reproduced.
Displaying the order of recording on the first disc-shaped recording medium,
By blinking the area corresponding to the data amount of the previous blinking display on the second bar graph-like display, whether or not it is possible to record without leaving the selected information signal before recording / reproducing, It is possible to visually grasp the remaining amount after recording.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing an audio device according to an embodiment of the present invention. In response to the operation of the operator detected in the operation block 2, the audio device 1 switches the operation of the compact disk block (CD block) 4 and the mini disk block (MD block) 5 by the system control circuit 3 to make it compact. A compact disc is reproduced by the disc block (CD block) 4, and a mini disc is recorded and reproduced by the mini disc block 5. At this time, the system control circuit 3 drives the display block 6 to display various information.

Here, this compact disc block 4
In the compact disc to be processed, a lead-in area, a program area, and a lead-out area are formed in order from the innermost circumference side, and audio data is recorded in this program area.

The audio data recorded on this compact disc is converted into a recording data string by prescribed data processing after adding an error correction code, a sub-code, etc. in a predetermined block unit, and corresponds to this recording data string. Thus, pits are sequentially formed and recorded in the program area. The audio data is formed so that it can be surely reproduced by performing an error correction process with this error correction code, and the subcode causes a gap between the tracks of the audio data, a reproduction position,
It is designed to be able to detect the accumulated playback time.

Further, the compact disc records the management information of the audio data in the lead-in area. That is, a compact disc is recorded in the lead-in area with a subcode added to the data of the specified format.
C (Table Of Contents) is formed. With this TOC, the compact disc records the total reproduction time of the audio signal recorded in the program area, the reproduction time of each performance (hereinafter referred to as music), the recording start position of each music, and the like. As a result, the compact disc is formed so that the lead-in area can be reproduced to detect the time information such as the total playing time, and the remaining reproduction time can be determined based on the management information and the subcode recorded in the program area. A detection process, a reproduction process by so-called program selection, and the like can be executed.

FIG. 2 is a block diagram showing the structure of the compact disc block 4. The compact disc block 4 drives the compact disc 11 to rotate by the spindle motor 12. In this state, the compact disc block 4 emits a laser beam from the optical pickup 13. Here, the optical pickup 13 is held so as to be movable in the radial direction of the compact disc 11, so that in the compact disc block 4,
The TOC is formed so that the TOC can be reproduced from the lead-in area by moving the optical pickup 13 as required, and a desired music piece can be selected based on the reproduced TOC.

Further, the optical pickup 13 receives the return light from the compact disc 11 by a plurality of photodetectors, and in the compact disc block 4, the servo circuit 14 drives the optical pickup 13 based on the light reception results to perform tracking control. , Focus control. Further, the optical pickup 13 generates a reproduction signal RF whose signal level changes in accordance with the amount of return light from the output signals of these photodetectors, and an amplifier circuit 15 amplifies the reproduction signal RF with a specified gain to perform digital signal processing. Output to the circuit 16.

The digital signal processing circuit 16 is formed of an integrated circuit and operates according to the operation mode set by the system control circuit 17 of the compact disc block 4. That is, the digital signal processing circuit 16
The EFM (Eight to Fourteen Modulation) demodulation circuit 19 detects a reproduction clock from the reproduction signal RF and outputs the reproduction clock to the speed control circuit 20.
The speed control circuit 20 drives the spindle motor so that the reproduction clock has a prescribed frequency, and thereby the compact disk 11 drives the compact disk 11 to rotate under the constant linear velocity condition.

Further, the EFM demodulation circuit 19 binarizes the reproduction signal RF, converts the reproduction signal RF into serial data based on the reproduction clock, and EFM demodulates the serial data. The deinterleave circuit 21 outputs the output data of the EFM demodulation circuit 19 to a random access memory (RA
M: Random Access Memory) 22 for deinterleave processing. Further, the deinterleave circuit 21
The data stored in this random access memory 22 is C
The error correction code is output to the IRC error correction circuit 23, and error correction processing is performed by the error correction code added to the audio data.

As a result, the compact disc block 4
Then, the audio data is correctly decoded to generate a digital audio signal, and the digital audio signal is band-limited by the digital filter 24. When dubbing the compact disc 11, the compact disc block 4 outputs this digital audio signal DA to the mini disc block 5 (FIG. 1). On the other hand, when the compact disc 11 is simply reproduced, it is converted into the audio signal SA which is an analog signal through the digital-analog conversion circuit (D / A) 25, and is output to the speaker through the amplifier circuit (not shown).

For such an audio data reproducing system, the digital signal processing circuit 16 applies the subcode SUB added to the audio data to the system control circuit 1.
Output to 7. Further, the system control circuit 17 controls the operation of the compact disc block 4 so as to reproduce the lead-in area when the compact disc 11 is loaded and the power is turned on, and the compact disc block 4 is obtained from the lead-in area. The TOC data is input from the digital signal processing circuit 16.

As a result, the system control circuit 17 causes the TO
From the data of C, the total playing time of the compact disc 11, the number of recorded songs, and the playing time of each song can be detected and displayed on the display block 6 via the system control circuit 3 as needed. Also, from the TOC data,
The recording start position of the music can be detected. Based on the detection result, the optical pickup 13 can be moved based on the sub-code SUB to reproduce the desired music, and the music can be input via the system control circuit 3. The program can be played back according to the performance sequence.

During playback, the subcode SUB
Based on, the accumulated playback time of the compact disc 11,
The system control circuit 3 detects the remaining playback time and, if necessary,
Is displayed on the display block 6, and similarly, the reproduction time of each music and the remaining reproduction time of each music can be displayed.

On the other hand, the mini disk to be processed by the mini disk block 5 has a lead-in area, a program area, and a lead-out area formed in this order from the innermost side, and extends from the inner side to the outer side. A pre-groove that forms a guide groove for the laser beam is formed in a spiral shape. This pre-groove is formed to meander by a so-called wobble signal, and in a compact disc, tracking control is performed based on this pre-groove, and the address of the recording / reproducing position can be detected based on this meander. Has been done. The mini disk is recorded in the program area with the pre-groove as a reference, after the data compression of the audio data undergoes the same data processing as the compact disk.

Further, the mini disc, like the compact disc, records the management information of the audio data recorded in the program area in the lead-in area. That is, in the mini disc, the data of the prescribed format is recorded by the pre-format on the inner circumference side of the lead-in area, and the P-TOC is formed by this data. Further, the mini disc is formed so that the following lead-in area can be updated with the recording and reproduction of the audio data, whereby the U-TOC is formed in the remaining lead-in area.

Here, the P-TOC is formed by a plurality of sectors, and the U-TOC, which is a read-only area formed on the mini disk by these sectors, is mainly managed. That is, FIG. 3 is a chart showing the P-TOC of the sector 0 among the P-TOCs of these plural sectors. P for this sector 0
In the -TOC, the first 8 bits x 4 x 6 area is assigned to the header, and a synchronization pattern formed by arranging 1-byte data of all 1s or all 0s is assigned to this header. Further, the upper address and the lower address of the cluster (cluster H and cluster L) are divided and assigned to this header.

Further, after the header, a character code of "MINI" is assigned by an ASCII code, and the type of the disc is specified by this. Following this, the disk type and recording level data are assigned, and the track number (First TNO
), The track number (Last TNO) of the last track number is recorded. In addition, the start address (P
O), the light amount adjustment area address (PC), the U-TOC area start address (UST), and the recordable area start address (RST) are recorded. With this information, the mini disk is formed so that the U-TOC area, program area, etc. can be accessed.

Subsequently, this P-TOC is set to be capable of recording pointers (P-TNO) of each music for reproduction only for 255 in sequence, and a start address and an end address corresponding to each pointer are sequentially recorded. It is done like this. As a result, in the program area of the read-only mini disk, the so-called hybrid type mini disk (which is a mini disk formed by dividing the program area into a read-only area and a recordable / playable area), The track number of the first song ahead (First TNO), the track number of the last song (Last TNO
No) can detect the number of songs recorded. In this type of program area, the recording position of each music piece can be confirmed from the pointer (P-TNO) of each music piece and the corresponding start address and end address. Is converted into time information so that the playing time of each song can be confirmed.

On the other hand, in the hybrid type mini disc and the mini disc in which the entire program area is formed in the recordable area, the lead-out area (PO) and the start address (RS) of the recordable area are recorded.
T) can be detected to detect a recordable / reproducible area. In addition to this, in this type of mini disc, the recording position of each song recorded in this recordable and reproducible area can be confirmed by referring to the U-TOC from the start address (UST) of the U-TOC area. It is formed so that the unrecorded area can be detected.

That is, the U-TOC is formed of a plurality of sectors, like the P-TOC, and manages the recordable and reproducible area formed on the mini disk by these sectors. FIG. 4 shows a U-TOC of these plural sectors.
9 is a diagram showing a U-TOC of sector 0. This sector 0
In the U-TOC, the leading 8 bits × 4 × 7 area is assigned to the header, and a synchronization pattern formed by arranging all 1 or all 0 1-byte data is assigned to this header. Also, in this header, the upper and lower addresses of the cluster (cluster H and cluster L)
Are divided and assigned.

Subsequently, the U-TOC is maker code (Ma
ker code), model code (Modelcode), track number of first song (First TNO), track number of last song (Last TNO). Next, the sector used status (Used Secter), the disk serial number (Disc Serial NO), and the disk ID with the data of all 0s sandwiched between them.
(Disc ID) etc. are recorded.

Further subsequently, the U-TOC is set so that 255 pointers (P-TNO) can be sequentially recorded for each music recorded in the recordable and reproducible program area. Here, in the mini-disc, there is a case where a desired piece of music among a plurality of pieces of music recorded continuously is erased. Further, it may be possible to separately record a music piece in the erased area, and further, it is possible to execute these processes by a single recording process. In these cases, for example, a case where the newly recorded music piece has a longer playing time than the erased area may be considered. Even in such a case, the mini disc can record the newly recorded music in this erased area and record the rest in another unrecorded area so that the erased area can be effectively used. Has been done. Here, each group of pieces of music thus discretely recorded is called a part.

U-TOC is a pointer (P-TNO)
The start address and the end address of each of these parts are sequentially recorded by the start address and the end address. Corresponding to the start address and end address, the mode information (Track mode) of each part and the link pointer (Link-P) that specifies the subsequent parts and has the same expression format as the pointer (P-TNO) are recorded. It is designed to be done. As a result, in this type of mini-disc, if a link pointer is set for each song after reproducing parts based on the start address and end address corresponding to the pointer (P-TNO) of each song, Each music piece can be reproduced by following this link pointer and sequentially reproducing the following parts based on the start address and end address of the corresponding pointer (P-TNO).

Also in the P-TOC, the pointer (P-TNO) designates the start address and end address of each part. In the case of the P-TOC, the reproduction-only area is managed and this reproduction-only area is managed. Since each piece of music is recorded as one part in the area, data of all 0s is recorded as data corresponding to this link pointer (Fig. 3).
TNO) designates each song corresponding to the track number.

Thus, in the recordable and reproducible mini disk, the pointer (P-TNO) of each music and the corresponding link pointer are sequentially traced to obtain the cumulative value of the address data from the start address and the end address. Is converted into time information so that the recording time of each music can be confirmed, and these recording times can be accumulated to detect the entire recording time. For the remaining recording time, which is the opposite of this, refer to P-TO
It is possible to detect by subtracting the cumulative time thus detected from the total recordable time detected by C.

Further, the accumulated reproduction time, the remaining reproduction time, the accumulated recording time, and the remaining recording time can be detected from the playing time of each music thus detected and the recording / reproducing position detected by the pre-groove. ing.

FIG. 5 is a block diagram showing a mini disk block 5 for reproducing this mini disk. The mini disk block 5 rotationally drives the mini disk 31 with a spindle motor 32. In this state, the mini disk block 5 emits a laser beam from the optical pickup 33. Here, the optical pickup 33, together with the modulation coil 34 held so as to face each other with the mini disk 31 sandwiched therebetween, together with the sled mechanism 35, the mini disk 31.
In the mini disk block 5, the optical pickup 33 and the modulation coil 34 are moved as necessary so that the P-TOC and U-TOC can be reproduced from the lead-in area. In addition, it is formed so that the U-TOC can be updated,
It is formed so that a desired music piece can be recorded and reproduced on the basis of OC and U-TOC.

Further, the optical pickup 33 receives the returned light from the mini disk 31 with a plurality of photodetectors, and the mini disk block 5 amplifies the received light results via an amplifier circuit 36 and outputs the amplified result. At this time, the optical pickup 33 performs a calculation process on the light reception result to thereby obtain a tracking error signal TE whose signal level changes according to the tracking error amount and a focus error signal F whose signal level changes according to the focus error amount.
E, A wobble signal whose signal level changes following the meandering of the pre-groove is generated. Also optical pickup 33
Indicates that the light amount of the laser beam is intermittently raised at the time of recording, while at the time of reproduction, the reproduction signal MO whose signal level changes according to the change of the polarization plane of the return light.
Generate

The servo circuit 37 moves the objective lens 33a of the optical pickup 33 vertically and horizontally so that the signal level of the focus error signal FE and the tracking error signal TE becomes 0 level. Tracking control. Further, the servo circuit 37 rotationally drives the spindle motor 32 so that the center frequency of the wobble signal becomes a specified frequency, thereby rotating the mini disk at a specified rotational speed. Further, the servo circuit 37 drives the sled mechanism 35 under the control of the system control circuit 38, thereby moving the optical pickup 33 and the modulation coil 34 to a desired recording / reproducing position.

The address decoder 39 generates a reproduction clock based on the wobble signal. The address decoder 39 frequency-demodulates the wobble signal to detect the address data recorded by the meandering of the pre-groove. The address decoder 39 outputs the detected address data to the encoder / decoder 40 and the system control circuit 38, and thereby the system control circuit 38.
In, the recording / reproducing position can be detected.

At the time of reproduction, the encoder / decoder 40 binarizes the reproduction signal output from the amplifier circuit 36, and then converts it into serial data with the reproduction clock as a reference. Further, the encoder / decoder 40 performs EFM demodulation on this serial data, then executes error correction processing, and outputs the resulting audio data to the memory controller 42. On the contrary to these processes, at the time of recording, the encoder / decoder 40 converts the audio data input via the memory controller 42 into a prescribed data structure and then EFM-modulates it, thereby generating a recording data string. .

At the time of recording, the drive circuit 41 drives the modulation coil 34 in accordance with this recording data string, whereby a modulation magnetic field corresponding to the recording data string is applied to the irradiation position of the laser beam output from the optical pickup 33. Apply. Thereby, in the mini disk block 5, desired audio data can be recorded by applying the thermomagnetic recording method.

During reproduction, the memory controller 42 temporarily stores the audio data input from the encoder / decoder 40 in the large-capacity random access memory 43, and then outputs it to the audio compression encoder / decoder 44. At this time, the memory controller 42 outputs the audio data at a data transfer rate that is ½ of that at the time of storage. As a result, in the mini disk block 5, the audio data is reproduced from the mini disk 31 at a double transfer rate at the time of reproduction, and the random access memory 43 is used as a buffer memory to discretely define the parts defined by the link pointer. Even when playing, sound breaks can be effectively avoided.

On the other hand, the memory controller 42
During recording, the audio data output from the audio compression encoder / decoder 44 is temporarily stored in the random access memory 43 and then output to the encoder / decoder 40. At this time, the memory controller 42 outputs the audio data at a data transfer rate twice as high as that at the time of storage. Thus, in the mini disc block 5, at the time of recording, audio data is recorded on the mini disc 31 at a double transfer rate, and the random access memory 43 is used as a buffer memory to decompose one music piece into parts, Even when sequentially recording in the recordable area that remains discretely in the area, it is possible to effectively avoid the sound break and perform recording.

The audio compression encoder / decoder 44 decompresses the audio data output from the memory controller 42 during reproduction, and outputs the digital audio signal D.
A is output. When the mini disk 31 is simply reproduced, it is converted into an analog audio signal SA through the digital-analog conversion circuit 46 and output to the speaker through an amplifier circuit (not shown).

On the other hand, the audio compression encoder / decoder 44 uses the audio signal SA that is sequentially input during recording.
Is converted into a digital audio signal by an analog-digital conversion circuit 47, and the digital audio signal is data-compressed to generate audio data.
When dubbing the compact disc 11, the digital audio signal DA output from the compact disc block 4 is data-compressed to generate audio data, and this audio data is stored in the memory controller 4.
Output to 2. As a result, in this audio device 1,
The audio signal of the compact disc 11 can be dubbed to a mini disc.

In the audio data recording / reproducing system, the encoder / decoder 40 reproduces the P-TOC and U-TOC data obtained by reproducing the lead-in area and outputs it to the system control circuit 38. To do. Further, the drive circuit 41 is driven based on the U-TOC data output from the system control circuit 38, thereby updating the U-TOC of the mini disk 31.

In response to this, the system control circuit 38
When the mini disk 31 is loaded and the power is turned on, the operation of the mini disk block 5 is controlled so that the lead-in area is reproduced, and the encoder / decoder 40 controls the P-TOC and U-TOC. Capture data. Further, the system control circuit 38 forms a table formed by the pointer (P-TNO), the start address, the end address, the link pointer, etc. described above with reference to FIG. 4 in the internal memory based on the fetched U-TOC data. The overall operation is controlled based on this table, and the audio signal recorded on the mini disk 31 is reproduced.

Further, the system control circuit 38 uses the table formed therein as a reference, and the system control circuit 3
Controlled by, the audio signal input from the external device and the audio data output from the compact disc block 4 are recorded on the mini disc 31, and the table formed inside is sequentially updated corresponding to the recording process. Further, the system control circuit 38 outputs the data of the table formed inside the mini disk to the encoder / decoder 40 when the power of the audio device is turned off or when the mini disc is ejected.
Update the contents of

When the recording / reproducing process is executed in this way, the system control circuit 38 detects the total recordable time of the mini disk 31 from the P-TOC data, as described above with reference to FIG. Furthermore, by sequentially tracing the start address of each part from the U-TOC data, accumulating the address data, and converting it to time information,
The playing time of each song, the number of recorded songs, and the playing time of the entire recorded song are detected and displayed on the display block 6 via the system control circuit 3 as required.

Further, the system control circuit 38 detects the remaining recordable time by subtracting the performance time of the entire recorded music obtained in this way from the total recordable time, and similarly, the system control circuit 3 is also operated if necessary. Is displayed on the display block 6 via. Further, the system control circuit 38 uses the address data obtained from the address decoder 39 on the basis of these address data and the wobble signal to determine the accumulated reproduction time, the remaining reproduction time, the accumulated recording time, the remaining recording time, etc. during recording and reproduction. Detect and display.

The audio device 1 displays the time information thus obtained from the compact disc block 4 and the mini disc block 5 on the display block 6 as needed (FIG. 1). In this display, the audio device 1 displays the time information so that the progress of dubbing can be visually and sensibly grasped during dubbing.

That is, the display block 6 (FIG. 1) is formed by a liquid crystal display panel 49 and a peripheral circuit for driving the liquid crystal display panel. In the liquid crystal display panel 49, rectangular segments are continuously arranged in a straight line. Thus, the bar graph-like displays 50 and 51 can be formed. In the case of this embodiment, the bar graph-shaped displays 50 and 51 can be formed by 20 segments each. The arrangement of the segments corresponds to the arrangement of the compact disc 11 and the mini disc 31 in the audio device 1, and the segments are arranged in two rows in the vertical direction, and the compact disc 11 and the mini disc 31 are arranged at the left end of the arrangement. Corresponding to "C
Character display portions of "D" and "MD" are formed. As a result, in the audio device 1, in the operation mode in which the compact disc is selected and the operation mode in which the mini disc is selected, the character display portion is turned on so that the user can know the operation mode.

On the left side of this character display, stylized symbols 52 and 53 of the compact disc 11 and the mini disc 31 are formed, respectively. Here, the symbols 52 and 53 are formed by a set of substantially fan-shaped segments.
In the audio device 1, the substantially fan-shaped segments are sequentially lit cyclically to reproduce compact discs and record / reproduce mini discs. Visually display the state of being

Therefore, in the display block 6, when the audio signal of the compact disc 11 is dubbed on the mini disc 31, both the symbols 52 and 53 are cyclically displayed, which allows the user to easily and surely operate the operation mode. You can check. It should be noted that the symbol 53 on the side of the mini disk is formed so as to surround the oval display by the rectangular display showing the case, so that in the audio device 1, the symbol similar to the outer shapes of the compact disc 11 and the mini disc 31 is formed. Is displayed so that the operating states of the compact disc block 4 and the mini disc block 5 can be reliably identified.

Further, between the symbols 52 and 53 and the character display, an arrow-shaped display portion is formed from the symbol 52 of the compact disc 11 to the symbol 53 of the mini disc 31, and the display portion of the arrow is displayed during dubbing. It is lit to visually indicate the flow of audio signals. As a result, in the audio device 1, the user can easily and surely grasp the dubbing operation mode by visually observing the display of the arrow while the symbols 52 and 53 are cyclically displayed. Has been done.

Further, in this liquid crystal display panel 49,
A character display portion 55 is formed on the lower side and the right end of the bar graph display, and the character display portion 55 displays the track number being reproduced,
The time information is displayed so that the accumulated reproduction time, remaining reproduction time, recordable time, accumulated recording time, remaining recording time, etc. of the compact disc 11 and the mini disc 31 can be accurately confirmed. .

Thus, in the audio device 1, the bar graph-like displays 50 and 51 are used so that the progress of dubbing can be visually and sensibly grasped at the time of dubbing. Is reproduced, and even when only the mini-disc 31 is recorded and reproduced, the operation status can be visually and sensibly grasped.

The display of the display block 6 is formed under the control of the system control circuit 3 which controls the operation of the audio apparatus 1 as a whole. That is, the system control circuit 3 turns on the character display of "CD" when the user operates the operator to select the operation mode of the compact disc. When the reproducing operator is operated in this state, the symbols 52 of the compact disc 11 are cyclically displayed.

Further, the system control circuit 3 switches the display of the character display section 55 in response to the user's operation, and reproduces the accumulated reproduction time and the reproduction remaining time of the compact disc 11 as a whole.
The playback time and remaining playback time of each song are displayed. Further, all the segments arranged side by side in the character display of "CD" are turned on to form the bar graph display 50. In this state, the system control circuit 3 operates the compact disc block 4
On the basis of the time information obtained from the system control circuit 17 of FIG. 1, the playback position in the total playing time of the compact disc 11 is detected, and the segment at the corresponding position counted from the left end of this bar graph display is displayed in blinking. In the drawing, the blinking segment is indicated by a star). That is, the system control circuit 3 sets the entire length of the bar graph display 50 corresponding to the total playing time of the compact disc 11 in a state where all the segments are lit, and sets the left end to the playing start position. The integrated playback time is detected from the playback position obtained from the subcode,
The segment corresponding to this accumulated playback time is displayed in blinking.

As a result, even if the recording time differs depending on the compact disc 11, the system control circuit 3 can
The length of this bar graph display is set so as to represent the total reproduction time of the compact disc 11, and the reproduction position is displayed on this bar graph. This gives the user
It is possible to visually comprehend the status of reproduction such as when the compact disk 11 is reproduced almost half, and the usability of the audio device can be improved accordingly. The accumulated playback time and remaining playback time can also be easily and visually ascertained from the left side of this blinking display, the length of the bar graph, and the length of the right side of the bar graph. Can be displayed as character information and accurate time information can be detected.

When the compact disc reproduced by the compact disc block 4 is a so-called single CD, the system control circuit 3 does not allocate the length of the bar graph display 50 by lighting all the segments to the total playing time of the compact disc. The length of the bar graph display 50 by lighting all segments is 74 minutes,
The playing time assigned to one segment is set (that is, in the case of this embodiment, the total number of segments is 20, resulting in 3.7 minutes playing time per segment). Is lit to form the bar graph display 50 described above.

On the other hand, when the compact disc 11 is program-reproduced, the system control circuit 3 effectively utilizes the bar graph display 50 at the time of music selection to assist the user in music selection work. That is, when the user selects the operation mode of the program reproduction, the system control circuit 3 switches the display of the character display section 55 and displays the track number and recording time of each music recorded on the compact disc 11 in response to the user's operation. It is displayed on the character display section 55. Further, the system control circuit 3 turns on all the bar graph-like displays 50 on the compact disc side, and when the user selects a desired music piece, the start address and end address of the corresponding track are detected.

Subsequently, when the system control circuit 3 turns on all the segments of the bar graph display 50, the entire length of the bar graph display 50 is reduced to the compact disc 1.
The total playing time is set to 1, and the number of segments of the playing time corresponding to the total length of the bar graph display is detected from the playing time of the music selected by the user. At this time, when the playing time of the music selected by the user is less than one segment, the system control circuit 3 sets the number of corresponding segments to the value 1. Then, the system control circuit 3
The left end of the bar graph display 50 is set to the lead-in area side, the segment position corresponding to the music selected by the user is detected from the start address, and the bar graph display 50 blinks for the number of segments detected before this position. indicate. Also in this case, when the compact disc 11 is a mini-CD, the system control circuit 3 does not set the total length of the bar graph display 50 by lighting all the segments to the total playing time of the compact disc 11, and
The bar graph display 50 is formed by setting the playing time per segment to 3.7 minutes.

As a result, in this display,
The position and time of the music selected by the user can be sensuously displayed, and the user's selection operation can be assisted. Incidentally, when the reproduction of this program selection is started, the system control circuit 3 blinks the segment corresponding to the reproduction position as in the case of the previous reproduction operation, and lights the remaining segments.

On the other hand, when the user selects the operation mode of the mini disk, the system control circuit 3 turns on the character display (MD) of the mini disk instead of the character display (CD) of the compact disk 11. Further, when recording / reproducing of this mini disk is started, the symbol 53 of the mini disk is cyclically displayed. Further, in response to the user's selection operation, the character display section 55 displays the track number and recording time of the music to be recorded / reproduced, the accumulated recording time, the accumulated reproduction time, the remaining recording time, the recordable time, and the like.

Further, the system control circuit 3 displays a bar graph display 51 on the mini disk side instead of the bar graph display on the compact disk 11 side. At this time, when the mini disc is reproduced in the normal mode, the entire length of the bar graph display when the mini disc is reproduced in the normal mode is 74 minutes (which is the standard recordable time of the mini disc). 1 to correspond to the playing time
Set the playing time per unit segment to be allocated to the segment, and display the bar graph like the total recording time of the mini disk detected by following the link pointer.
Light segment 1 from the left end. In order to hide
In this embodiment, the number of segments of the bar graph display 51 is selected to be 20, so that a data amount corresponding to 3.7 minutes is allocated to one segment.

Further, the system control circuit 3 similarly calculates the total playing time of a song having a track number smaller than that of the song being played, and from the start of playing the song being played from the address data detected from the wobble signal. Calculate the elapsed time to the current time. The system control circuit 3
The two pieces of time information calculated in this way are added, and the reproduction position at which the user reproduces and feels the mini disc is detected from the time information. Further, the system control circuit 3
The segment corresponding to this added time is switched to blinking display. As a result, the audio apparatus 1 is capable of visually and sensibly grasping the reproduction status even when reproducing a mini disk.

On the other hand, in the program reproduction,
At the time of selection, similarly, the segment of the bar graph display 51 is turned on for the total recording time of the mini disk. In this state, as in the case of the compact disc 11, the segment corresponding to the music selected by the user is switched to blinking display. At this time, the system control circuit 3 blinks the number of segments corresponding to the playing time of the music selected by the user so that the entire length of the bar graph display 51 when all the segments are lit becomes 74 minutes. To set.
Also, as in the case of playing in the normal mode, the total playing time is calculated for the song whose track number is smaller than the track number corresponding to the song selected by the user, and the position of the segment to start blinking display is calculated from this total playing time. To detect. As a result, the system control circuit 3 assists the user in the selection operation by the bar graph display 51,
When the user instructs the playback operation, the bar graph display 51
To the same display as in the normal mode.

On the other hand, when recording on a mini disk, the segment of the bar graph display 51 is turned on for the total recording time of the audio signals already recorded on the mini disk. In this state, if the user selects an operation mode for recording an audio signal in an unrecorded area (hereinafter referred to as “additional recording”), the address data obtained from the wobble signal is used to start recording and then to the current time point. Time is accumulated by address data. Further, this accumulated value is converted into time information, and the bar graph display 51 for the total recording time which is turned on at the start of recording is sequentially extended and turned on by the amount of this accumulated time information. Further, the extended and lit first segment is displayed in blinking, thereby displaying the recording position.

On the other hand, when the audio signal is recorded also in the area where the music is already recorded (hereinafter referred to as the overwriting recording), similarly, only the total recording time of the audio signal already recorded on the mini disk is used. With the segment of the bar graph display 51 lit, the start address, end address, and link pointer are sequentially traced from the songs already recorded on the mini disc for the songs that the user wishes to leave on the mini disc. The total recording time is detected separately. When recording is started, the system control circuit 3 switches the segment following the separately detected total recording time to blinking display, and then starts recording by the accumulated value of address data obtained by sequentially detecting wobble signals. Detects the cumulative time to reach the present time. Furthermore, the system control circuit 3 calculates
The position of the blinking display is sequentially moved to the right side, and the display from the left end to the segment of the blinking display is switched to the lighting display. As a result, the system control circuit 3 displays the recording position and the cumulative recording time while displaying the data amount of the already recorded music.

In this overwriting recording, when the user selects the music to be overwritten, the system control circuit 3 is similar to the case of selecting the music in the program selection so as to assist the user's selection operation. Then, the bar graph display 51 is switched. As a result, in the audio device 1, even when recording the mini disc 31,
The recording position can be grasped visually and sensibly.

On the other hand, when dubbing the audio signal recorded on the compact disc 11 onto the mini disc 31, the system control circuit 3 turns on both the compact disc 11 and the mini disc character display (CD and MD). . When the dubbing is further started, the symbols 52 and 53 of the compact disc and the mini disc are cyclically displayed. Further, when the dubbing is started, the system control circuit 3 lights up the display of the arrow arranged between the symbols 52 and 53 and the character display, thereby displaying the flow of the audio signal. Also, the system control circuit 3
Is displayed on the character display 55 in response to the user's selection operation,
The track number and recording time of the music to be recorded / reproduced, accumulated recording time, accumulated reproduction time, remaining recording time, recordable time, etc. are displayed.

Further, the system control circuit 3 displays a bar graph display 5 of the compact disc 11 and the mini disc 31.
Turn on 0 and 51. At this time, the system control circuit 3
Calculates the total recording time of the audio signal already recorded on the mini disc by following the link pointer, and FIG.
As shown in (A), in the bar graph display 51 on the mini-disc side, the total length calculated so that the entire length of the bar graph display 51 when all the segments are lit corresponds to a playing time of 74 minutes. Illuminate the minutes segment of the playing time. In addition, here, a rectangular shape filled in with black indicates a lighted display segment, and a black frame display indicates a non-lighted segment.

The system control circuit 3 detects the total recording time from the TOC for the bar-graph display 50 on the compact disc side, and the total recording time is divided by the TOC corresponding to the bar-graph display 51 of the mini disc 31. Only light the segment. That is, in this case, the system control circuit 3 causes the bar graph-shaped displays 50 and 51 to be formed by 20 segments, so that one segment displays a playing time of 3.7 minutes. The segment of the state display 50 is displayed. Therefore, in the state shown in FIG. 6A, the total playing time of the compact disc 11 is 74 minutes which is equal to the total recordable time of the mini disc 31.

When the user selects the additional recording operation mode and starts dubbing in this state, the system control circuit 3 causes the sub-graph display 50 on the compact disc side to display a sub-display as shown in FIG. 6B. Corresponding segments are sequentially displayed in blinking according to the playback position detected through the code. As a result, in the bar-graph display 50 on the side of the compact disc, the blinking segments sequentially move from the left end to the right end as the dubbing progresses (FIG. 6 (C)).

On the other hand, in the bar-graph display 51 on the mini-disc side, the address data detected from the wobble signal is accumulated and the recording time from the start of recording to the current time is detected. Furthermore, the system control circuit 3
Shifts the position of this blinking display to the right sequentially by the accumulated time, and switches to the lighting display from the left end to the segment of this blinking display. As a result, the system control circuit 3 displays the recording position and the cumulative recording time while displaying the data amount of the already recorded music.

As a result, the system control circuit 3 allows the user who views the bar-graph displays 50 and 51 to see
The bar graph displays 50 and 51 are formed so that the reproduction status on the compact disk 11 side and the recording status on the mini disk side can be grasped at the same time, visually and sensibly. Further, the system control circuit 3 forms the bar graph-shaped displays 50 and 51 side by side, so that in the audio device 1, for example, when recording all the songs of the compact disc 11, it becomes difficult to record on the mini disc side. Can be grasped easily and surely, and thereby the situation of dubbing can be grasped easily and surely.

Further, in this embodiment, the time information is also displayed in the form of character information, so that the dubbing situation can be grasped in more detail, if necessary. In addition, by arranging the bar graphs 50 and 51 side by side with the symbols 52 and 53, and by showing the flow of the audio signal by the arrow display in this state, it is possible for the user to intuitively grasp the dubbing situation. The status of the compact disk and the status of the mini disk can be grasped without fail, and the usability of the audio apparatus 1 can be improved accordingly.

On the other hand, when the user selects the operation mode of overwriting recording on the mini disk 31 side,
The system control circuit 3 displays the bar graph display 50 on the compact disc 11 side in the same manner as in the case of additional recording, and also sequentially moves the position of blinking display.

In the bar-graph display 51 on the mini-disc side, the system control circuit 3 displays the bar-graph display for the total recording time of the audio signals already recorded on the mini-disc, as shown in FIG. 6D. With the segment of display 51 lit, the start address, end address, and link pointer are sequentially traced separately from the songs already recorded on the mini disc, and the total recording time To detect. When recording is started, the system control circuit 3 switches the segment following the separately detected total recording time to blinking display, and then starts recording with the accumulated value of address data obtained by sequentially detecting wobble signals. Detects the cumulative time to reach the present time. Further, the system control circuit 3 sequentially moves the position of this blinking display to the right by the amount of this accumulated time, and switches from the left end to the segment of this blinking display to the lighting display. As a result, the system control circuit 3 displays the recording position and the recording cumulative time while displaying the data amount of the already recorded music.

As a result, the system control circuit 3 forms the bar graph-like displays 50 and 51 so that the situation of the dubbing can be visually and sensibly grasped even in the case of overwriting recording on the mini disk 31 side.

On the other hand, when dubbing the audio signal recorded on the compact disc 11 by the program selection to the mini disc, the system control circuit 3 executes the processing procedure shown in FIG. 7, thereby displaying the bar graph. Use it effectively to help users select songs.

That is, the system control circuit 3 moves from step SP1 to step SP2, and when the user selects the program music selection mode, the operation mode is switched to the program selection mode. Here, as shown in FIG. 8 (A), the system control circuit 3 turns on the bar graph displays 50 and 51 of the compact disc 11 and the mini disc 31. At this time, the system control circuit 3 follows the link pointer to calculate the total recording time of the audio signal already recorded on the mini disk, and in the bar graph display 51 on the mini disk side, the bar graph shape when all the segments are turned on. 3.7 minutes of playing time is assigned to one segment so that the total length of the display 51 corresponds to 74 minutes of playing time, and the calculated total playing time segment is lit. On the compact disc side, all segments are turned on.

In this state, the system control circuit 3 then proceeds to step SP3 and inputs the music selected by the user. Then, the system control circuit 3 performs step S
Moving to P4, by data communication with the system control circuit 17, the start address and end address of the music selected by the user are detected, and the playing time of this music is detected.

Subsequently, the system control circuit 3 proceeds to step S
The program moves to P5, where it is judged whether or not the program playing time selected by the user exceeds the remaining recording time of the mini disk, and if a negative result is obtained, the program moves to step SP6.

Here, the system control circuit 3 is shown in FIG.
As shown in, a bar graph display 50 on the compact disc 11 side from the start address and end address
In, the corresponding segment is displayed in blinking, and at the same time, in the bar graph display 51 on the minidisk 31 side, the corresponding segment is displayed in blinking.

In this blinking display on the mini-disc side, when an audio signal is additionally recorded on the mini-disc 31, from the segment on the right side of the lit segment (that is, the data amount of the recorded audio signal), The segment blinks for the playing time of the selected music. On the other hand, when the audio signal is overwritten and recorded on the mini disk 31, the playing time is accumulated by following the link pointer with respect to the music selected by the user to be left on the mini disk, and the accumulation is performed from the left end of the bar graph display 51. From the next segment that has moved to the right by the amount of time, the segment blinks for the playing time of the selected music.

As a result, the system control circuit 3 displays the data amount of the audio signal dubbed from the compact disc side to the mini disc in response to the user's music selection operation on the bar graph together with the recorded / reproduced area. It is designed to improve usability.

Thus, the system control circuit 3, when the segment is displayed in a blinking manner in this way, moves to step SP7 and waits for a recording start operation. When the subsequent music selection operation is executed instead of the recording start operation, the system control circuit returns to step SP3 and repeats a series of processes for the music selected by the user.

As a result, for example, when the user selects a song recorded at the beginning of the compact disc 11 for about 11.1 (3.7 minutes × 3) minutes in the additional recording operation mode (FIG. 8B). The system control circuit 3 blinks and displays three corresponding segments in the bar graph displays 51 and 50 on the mini disc 31 side and the compact disc 11 side, and then accepts the user's subsequent song selection. Subsequently, when the user selects a music piece of about 14.8 (3.7 minutes × 4) minutes recorded at a substantially middle position of the compact disc 11 (FIG. 8C), the system control circuit 3 causes the compact disc On the 11 side, four corresponding segments are switched to blinking display, and on the minidisk side, four segments following three blinking display are switched to blinking display.

As a result, the system control circuit 3 responds to a series of selection operations by the user and sequentially displays the bar graph display 50.
When the performance time selected by the user exceeds the remaining recording time of the mini disk 31, step SP is performed.
When a negative result is obtained in step 5, step S
Move to P8. Here, the system control circuit 3 is shown in FIG.
As shown in (D)), the bar graph display is switched, and on the right side of the bar graph display 51 on the mini disk side,
The word "OVER" is displayed to warn the user that the playing time selected by the user exceeds the remaining recording time of the mini disk 31. Incidentally, in this case, in the bar-graph display 51 on the mini-disc side, the segment corresponding to the music left by the user on the mini-disc is lit from the left end and all the remaining segments are blinked.

In this way, the system control circuit 3 can perform the music selection operation by visually observing the displays of the bar graph-shaped displays 50 and 51. Therefore, before the warning is issued, the recording is performed by the bar graph-shaped displays 50 and 51. The user can be made aware that the remaining time may be exceeded. That is, the user can confirm that the remaining recordable area is reduced by the bar-graph display 51 on the minidisk side. In this case, the time information character display portion 55 (FIG. 1) determines whether or not recording is possible. This warning display 59 can be used to confirm this erroneous judgment even if the user mistakenly selects that recording is possible. As a result, the system control circuit 3 can visually and sensibly grasp the result of the program music selection work by the bar graph display, and also displays the time information and the warning if necessary, so that the user can It is designed so that the desired piece of music can be dubbed without fail.

Thus, after the warning is displayed in this way, the system control circuit 3 moves to step SP9 and waits for the user's key input, and affirms the user's selection of music by saying that recording is to be made within the user's recording range. When it receives, it moves to step SP7. On the other hand, when the user determines to reselect the music and receives a key input to deny the user's music selection, the system control circuit 3 returns to step SP3 and waits for the user's music selection operation again.

On the other hand, when the user operates the recording start operator by executing a series of music selection processing in this manner, the system control circuit 3 proceeds from step SP7 to step SP7.
10, the control command is issued to the compact disc block 4 and the mini disc block 5 to start dubbing, and then the process proceeds to step SP11 to end this processing procedure.

When the system control circuit 3 starts dubbing in this way, as shown in FIG. 8 (E), in the mini-disc side bar graph display 51, as in the case of additional recording and overwriting recording, respectively. Switch the display.
In the compact disc side bar graph display 50, the playing time of the music not selected by the user is accumulated while all the segments are lit, and the segment on the right side of the bar graph display 50 is the accumulated time. More blinking display is performed, and the segment of this blinking display is sequentially moved to the right side as the playback position is displaced.

In the above configuration, when the compact disc 11 (FIG. 2) is loaded into the compact disc block 4 and the power is turned on, the lead-in area is accessed and recorded in this lead-in area. The TOC is expanded in the memory of the system control circuit 17. As a result, the audio signal recorded on the compact disc 11 is transmitted to the system control circuit 17 by the T signal.
According to the OC, the music desired by the user is reproduced and output.

Similarly, when the mini disk 31 (FIG. 5) is loaded in the mini disk block 5 and when the power is turned on again, the lead-in area is accessed and the P-recorded in the lead-in area is accessed. TOC and U-TO
C is expanded in the memory of the system control circuit 38. As a result, the audio signal recorded on the mini disc 31 is reproduced and output as the music desired by the user in accordance with the P-TOC and U-TOC developed in the system control circuit 38. In addition, according to the P-TOC and U-TOC, an unrecorded area or the like is selected, audio signals that are sequentially input are recorded, and the U-TOC expanded in the system control circuit 38 is updated correspondingly. , U-TOC in the lead-in area is updated.

When the compact disc 11 is reproduced in this way, the system control circuit 17 of the compact disc block 4 detects the total recording time of the compact disc 11, the recording time of each song, and the number of songs from the TOC. Further, the reproduction position is detected by the subcode recorded together with the audio data, and the time information is displayed on the display block 6 by the system control circuit 3 which controls the operation of the entire audio apparatus 1.

Of these, the accumulated reproduction period, the remaining reproduction time, the reproduction time of each music, and the remaining reproduction time are displayed in characters through the character display section 55, which allows the user to switch the display contents as necessary. It is designed so that the time information of can be confirmed accurately. In addition to this, in a bar graph display 50 formed by continuously forming rectangular segments, the total recording time of the compact disc 11 is displayed by the length of the bar graph display 50, and a blinking display during this display. The playback position is displayed depending on the position.
As a result, through the bar graph display 50, the user can display the accumulated reproduction period, the remaining reproduction time, and the reproduction position.
It is designed to be visually and sensibly grasped.

Further, the compact disc 1 arranged on the left side of the bar graph-like display 50 of the compact disc 11.
The character display of 1 (CD) and the subsequent display of the symbol 52 indicate that the compact disc 11 is being played back, so that the user can visually and sensibly see that the compact disc 11 is being played back. It is designed to be able to grasp.

On the other hand, when recording / reproducing the mini disk 31, the system controller 38 of the mini disk block 5 sets the total recording time of the entire mini disk 31, the recording time of each music, and the number of musics to P-TOC and U. -The recording / reproducing position is detected by the address data recorded by the TOC and the meandering of the pre-groove, and the time information is displayed on the display block 6 by the system control circuit 3 which controls the operation of the entire audio apparatus 1. To be done.

In this display, the accumulated reproduction period, the remaining reproduction time, the reproduction time of each music, and the remaining reproduction time are displayed through the character display section 55, so that the user can
The display contents can be switched as needed to accurately confirm the time information. In addition to this, in the bar graph display 51 formed by continuously forming rectangular segments, the recording time of the mini disk 31 is displayed by the length of the bar graph display 51, and the blinking display position in this display. The recording / playback position is displayed by. As a result, through the bar-graph-shaped display 51, the user can reproduce, a reproduction accumulation period, a reproduction remaining time,
The reproducing position is formed so that the recording position, the recording accumulation period, the remaining recording time, and the recording position can be visually and sensibly grasped.

Further, the character display (MD) of the mini disk 31 arranged on the left side of the bar graph display 51 of the mini disk 31 and the subsequent symbol 53 display indicate that the mini disk 31 is being recorded / reproduced. As a result, the user can visually and sensuously understand the operation status.

On the other hand, when dubbing the audio signal recorded on the compact disc 11 to the mini disc 31, the compact disc 11 and the mini disc 3 are used.
One bar graph representations 50 and 51 are formed together. Here, in the bar graph display 50 of the compact disc 11, 3.7 minutes of playing time is assigned to one segment, the segments are lit for the playing time recorded in the compact disc 11, and detection is made via the subcode.
