[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus and a recording method, and can be applied to a magneto-optical disk apparatus for recording data such as music, for example, on a disk-shaped recording medium.

[0002]

2. Description of the Related Art Conventionally, in a magneto-optical disk drive,
There is a type in which continuous audio data is thermomagnetically recorded in a predetermined block unit so that the audio data can be discretely recorded on a magneto-optical disk.

That is, in this magneto-optical disk drive, sequentially input audio data is input to an audio compression circuit, divided into blocks at a predetermined cycle, and subjected to audio compression processing in units of blocks (hereinafter, blocks of this audio-compressed data are referred to as audio Sound groups).

Further, in the magneto-optical disk device, with respect to the audio data of this sound group, two sectors are formed by eleven consecutive blocks, and one cluster is formed by 36 sectors. Can be recorded in cluster units based on this sector.

That is, as shown in FIG. 6 in the form of a table, in this magneto-optical disk drive, each sector has 23 sectors.
52 bytes of data can be allocated, and the area represented by the vertical addresses "0" to "3" is allocated to the header.

Further, in the magneto-optical disk device, 12 bytes of the area of the vertical addresses "0" to "2" are allocated to a synchronization pattern (sync), and a predetermined synchronization pattern formatted therein is allocated thereto. The cluster address is recorded in the first and second bytes of the subsequent vertical address "3".

Here, in the magneto-optical disk device, these sectors are formed continuously on the magneto-optical disk, and 36 sectors are grouped to form a cluster. A 14-bit cluster management address is used. Addresses are assigned.

Further, in the magneto-optical disk device, a sector address is allocated following the cluster address, and the mode of the magneto-optical disk is subsequently recorded.

Following the header, the magneto-optical disk device forms a main data area of 2336 bytes,
Data desired by the user can be assigned to this area.

That is, as shown in FIG. 7, in an audio magneto-optical disk, mode data is 0 bits.
Data of 2h is allocated, data of 00h continues for 4 bytes following the header, and audio data is recorded subsequently. In the magneto-optical disk device, sound groups are assigned to the sectors formed in this manner as shown in FIG.

That is, in the even-numbered sector, the main data area following the 00h data of the vertical address "4" corresponding to the table of FIG. Is divided, and sound group data is sequentially allocated to each area.

Further, the area of "53" is allocated to the sixth sound group 5 with the vertical address remaining by dividing the main data area in this manner, and the area starting from the vertical address "5" of the odd-numbered sector is allocated to 6th sound group 5. The remaining data of the fifth sound group 5 is recorded.

Further, in the magneto-optical disk drive, the odd-numbered sector has a vertical address of "105".
The remaining area is divided in units of the area, and the remaining sound groups are assigned to each area.

Thus, in this type of magneto-optical disk drive, a sound group is formed by performing audio compression processing on sequentially input audio data, sectors are formed by the sound group, and clusters are formed by the sectors. Audio data can be recorded in units of this cluster.

That is, when audio data is recorded in cluster units in this manner, if a large-capacity memory circuit is used as a buffer memory, for example, if a track jump occurs due to vibration during recording, the cluster in which the track jump occurred is re-recorded. As a result, continuous audio data can be recorded on the magneto-optical disk without interruption.

Further, in the magneto-optical disk device, a recording area for recording audio data management data is formed on the inner peripheral side of the magneto-optical disk, and the main data of the cluster data is formed on the outer peripheral side of the recording area. Form a recording area.

Thus, in the magneto-optical disk device, audio data can be sequentially recorded in cluster units in the main data recording area.

On the other hand, in the recording area of the management data, management data composed of UTOC data is recorded.
Desired audio data can be reproduced with reference to the TOC data. That is, in the UTOC data, the management data is defined in units of sectors, like the main data, and the first to fourth sectors are standardized.

In the first to fourth sectors, the second to fourth sectors are defined as options, and in the first sector (that is, sector 0), as shown in FIG. After allocating the address of the cluster following the header, the data of 00h is recorded subsequently.

Further, in the first sector, after predetermined code data (Maker code, Model code) is allocated, data (First TNO, Last TNO) indicating the recording start position and end position of the main data and the like are allocated. It has been made to be.

At the vertical address "11" of the first sector, disc identification data can be recorded in 2 bytes, and then a pointer (P) indicating the position of a defective area in the main data recording area is recorded. -DFA), a pointer (P-
EMPTY) is assigned.

At the succeeding vertical address "12", a pointer (P-FRA) indicating the head position of the main data recorded in the main data recording area is assigned, and then a pointer indicating the recording start position of each data. (P-TNO1,
……, P-TNO255).

In the magneto-optical disk apparatus for recording and reproducing the audio signal, the pointer (P-FRA)
, P-TNO1,..., P-TNO255) can be detected.

That is, in the area below the subsequent vertical address "76", a start address (Start address) and an end address (End address) indicating a recording start position and a recording end position of main data are recorded. Pointers (P-FRA, P-TNO1, ……, P-TNO255)
In this case, the recording position of the start address is designated.

Thus, in the magneto-optical disk device, by detecting the start address and the end address designated by the pointer, the recording position of the music designated by the user can be detected.

That is, in the start address and the end address, as shown in FIG. 10, a 14-bit cluster address is recorded, followed by a 6-bit sector address and a 4-bit sound group address. Thus, in the magneto-optical disk device, audio data recorded in units of clusters can be subjected to processing such as cueing of music in units of clusters, sectors, and sound grape.

The recording unit specified by the set of start address and end address is called a part.

Further, in the UTOC data, mode data (Track mode) indicating the processing mode of each part is recorded following the start address, whereby copy-inhibited data, write-inhibited data, audio data, stereo data, Monaural data and the like can be identified, and furthermore, the presence or absence of an emphasis process can be identified.

On the other hand, in the end address,
Next, a link pointer (Link-
P) is recorded, and this link pointer (L
The recording position of the start address corresponding to this end address can be designated by ink-P).

That is, as shown in FIG. 11, when audio data is recorded for the first time on a magneto-optical disc on which no audio data is recorded, the magneto-optical disc apparatus sequentially performs the first, second,. Audio data is recorded so as to be continuous (see FIG. 11).
(A)).

In this case, the audio data of each performance is recorded on the magneto-optical disk with parts P1, P2, P3,... Designated by a set of start address and end address.

On the other hand, when the second music piece and the fourth music piece are erased and then the performance of the fifth music piece having a long playing time is recorded, continuous audio data is divided into the second music piece and the fifth music piece. Recording is performed by the fourth parts P2 and P4.

In such a case, in the magneto-optical disk, when the start address of the fifth music piece is designated by the pointer, the start position of the performance of the second part P2 can be detected by the start address. This part P2 is an end address paired with the address
The recording end position can be detected.

Further, in the magneto-optical disk, a pointer (P-FRA, P-TNO1,..., P-TNO2) of the fourth part P4 is designated by a link pointer (Link-P) following the end address.
The start address can be detected in the same manner as in 55), so that in the magneto-optical disk device, even if the recording and erasing processes are repeated, the UTOC is rewritten each time to make the recording area of the magneto-optical disk effective. The audio data can be recorded by utilizing this.

Thus, the pointers (P-FRA, P-
TNO1,... P-TNO255) are formed corresponding to each performance recorded on the magneto-optical disk, and the corresponding parts are designated together with the link pointer.

On the other hand, in the case where the second piece of audio data recorded continuously in such a manner is deleted, the magneto-optical disk device indicates the head position of the unrecorded area of the main data recording area. Pointer (P-EMPTY
) Designates this erased area.

That is, in the pointer (P-EMPTY), the start address of the corresponding part is designated in the same manner as the pointer (P-FRA, P-TNO1,..., P-TNO255), thereby In the magnetic disk device, for example, when the second and fourth songs are erased, the designation of the parts P2 and P4 designated by the pointers (P-TNO1, P-TNO2,. To the pointer (P-EMPTY) that indicates the start position of the file and the link pointer (Link-P) of the end address that forms a pair with the start address specified by this pointer. (FIG. 11B).

Thus, in the magneto-optical disk device, audio data between clusters specified by the start address and the end address is reproduced in cluster units, and then data processing is performed in sector units, so that the start address and end address are recorded. The performance specified by the sound group address can be reproduced,
As a result, audio data discretely recorded on the magneto-optical disk can be easily reproduced.

At this time, in the magneto-optical disk device,
In this way, audio data is recorded in cluster units,
By playing back audio data in cluster units, a large-capacity memory circuit is used as a buffer memory as in the case of recording. It is made so that it can be prevented beforehand.

Incidentally, in the second sector (sector 1) of the remaining sectors, as shown in FIG.
Headers and pointers (P-TNO1, P-TNO2,
...) And the like, the disc name and the track name can be assigned in ASCII code corresponding to the start address and the end address.

On the other hand, in the third sector (sector 2), as shown in FIG. 13, after the header and the like are formed similarly to the first sector, the pointer (P-
Pointers (P-TRD1, P-TRD1, P-TNO2, ...)
TRD2,...) Are formed.

As a result, in the third sector (sector 2), the pointers (P-TNO1, P-TNO2,.
…) For each performance (P-TRD1, P-TRD
Recording time (Track rec data and time) with TRD2, ……)
Etc. can be recorded.

Further, in the fourth sector (sector 4), pointers (P-TNA1, P-TNA1,
TNA2,...), And the disc name and the track name can be recorded in kanji code.

Thus, in this magneto-optical disk drive, audio equipment such as an analog tape player, LP record player, and compact disk player is connected as an audio information source, and the analog audio signal output from these audio equipment is converted into a digital signal. It converts audio data and records it, and connects digital audio equipment such as a compact disk player, digital audio tape recorder, and magneto-optical disk drive to record digital audio signals output from these digital audio equipment. It has been done.

[0045]

By the way, among audio devices serving as music information sources, for example, in a compact disc player, by setting a so-called program reproduction mode, a desired performance is reproduced in a music order desired by the user. be able to.

Therefore, in the magneto-optical disk drive, by connecting the audio equipment set in the program reproduction mode as described above and setting the recording mode, the recording / reproduction operation for each performance can be omitted and the order of the music desired by the user can be reduced. To record the desired performance. That is, once the audio equipment and the magneto-optical disk device are set, the operation until the end of recording can be omitted (this recording is hereinafter referred to as automatic recording).

However, for example, some compact discs have a performance time of only about 30 minutes as a whole.

Therefore, in the magneto-optical disk device, when a magneto-optical disk capable of recording for 60 minutes is loaded into the magneto-optical disk device and the performance of the compact disk is automatically recorded, after the performance on the compact disk player side is ended, I would record for 30 minutes without any sound.

In order to stop the silent recording, the user has to stop the magneto-optical disk device. Even in the event of such automatic recording, the operation of the user is actually required, and practically, There were still inadequate problems.

The present invention has been made in view of the above points, and is intended to propose a recording apparatus and a recording method capable of simplifying the entire operation when recording music information from audio equipment. is there.

According to the present invention, there is provided a recording medium for storing digital data to which an identifier for identifying a source for supplying digital data is added and management data for managing the digital data. And a first detecting means for detecting index information added to the digital data; a first detecting means for detecting index information added to the digital data; and a first detecting means for detecting index information added to the digital data. Second detecting means for detecting the continuity of the reproduction progress time information and for detecting the presence or absence of digital data, and a detecting result by the first detecting means when the discriminating means discriminates the first source. Recording of digital data input on the recording medium on the basis of the On the other hand, when the rewriting process is performed, when the determination unit determines that the source is the second source, the recording of the digital data input based on the detection result by the second detection unit on the recording medium is stopped, and after the recording is stopped. Control means for rewriting the management data is provided.

As a result, in this recording apparatus, regardless of the type of the source source, the recording operation is automatically terminated when the reproduction of the source source is stopped, thereby preventing useless silent recording from occurring. it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

(1) First Embodiment FIG. 1 is a block diagram of a recording / reproducing apparatus using a magneto-optical disk (mini disk) as a recording medium.

Reference numeral 1 denotes a magneto-optical disk on which a plurality of music pieces (audio data) are recorded, for example, which is rotated by a spindle motor 2. Reference numeral 3 denotes an optical head for irradiating the magneto-optical disk 1 with a laser beam. The optical head 3 outputs a high-level laser output intermittently during recording and heats the recording track to the Curie temperature. The laser output is switched to a relatively low level so that data can be detected from reflected light using the magnetic Kerr effect.

Therefore, the optical head 3 is equipped with a laser diode as a laser output unit, an optical system including a polarizing beam splitter and an objective lens, and a detector for detecting reflected light. Further objective lens 3
a is held by the biaxial mechanism 4 so as to be displaceable in the radial direction of the disk and in the direction of coming and going to and from the disk, so that the recording / reproducing apparatus can perform tracking control and focusing control. The entire optical head 3 can be moved in the radial direction of the disk by a sled mechanism 5, so that in the recording / reproducing apparatus, the optical head 3 can be moved to seek a desired recording track.

Reference numeral 6 denotes a magnetic head, which applies a modulation magnetic field whose polarity changes according to supplied data to the magneto-optical disk, and is arranged at a position facing the optical head 3 with the magneto-optical disk 1 interposed therebetween.

The recording / reproducing apparatus detects information from the magneto-optical disk 1 by the optical head 3 and supplies this information to the RF amplifier 7 in the reproducing operation. The RF amplifier 7 calculates the reproduced RF signal, the tracking error signal, the focus error signal, and the absolute position information (the absolute position information recorded as a pre-groove (fobbling groove) on the magneto-optical disk 1) by the arithmetic processing of the supplied information. , Address information, subcode information, a focus monitor signal, and the like. The extracted reproduction RF signal is supplied to the encoder / decoder unit 8. The tracking error signal and the focus error signal are supplied to a servo circuit 9, and the address information is supplied to an address decoder 10 and demodulated. Further, the focus monitor signal is transmitted to the system controller 1 constituted by a microcomputer, for example.
1 is supplied.

The servo circuit 9 includes a tracking error signal, a focus error signal,
Based on the output data of the above, various servo drive signals are generated by a track jump command, a seek command, rotation speed detection information, and the like, and the focus control and the tracking control are performed by controlling the two-axis mechanism 4 and the thread mechanism 5; 2 is constant angular velocity (CAV) or constant linear velocity (C
(LV).

The reproduced RF signal is subjected to EFM demodulation and decoding processing such as CIRC in the encoder / decoder section 8, and is temporarily written in the buffer RAM 13 by the memory controller 12. The reading of data from the magneto-optical disk 1 by the optical head 3 and the transfer of reproduced data from the optical head 3 to the buffer RAM 13 take 1.41 [Mbit].
/ sec].

The data written in the buffer RAM 13 is read out at a timing when the data transfer speed becomes 0.3 [Mbit / sec], and is supplied to the encoder / decoder unit 14. The data is subjected to reproduction signal processing such as decoding processing for audio compression processing in the encoder / decoder section 14, converted into an analog signal by the D / A converter 15, and supplied from the terminal 16 to a predetermined amplifier circuit section.
Thereby, for example, the audio signal is output as an L, R audio signal.

The address decoder 10 outputs the absolute position information obtained by decoding the pre-groove information or the address information recorded as data. These information are sent to the system controller 11 via the encoder / decoder 8. It is supplied and used for various control operations. Further, a PL for generating a bit clock for the recording / reproduction operation
The system controller 11 is also supplied with a clock detection signal for the L circuit and a monitor signal for a missing state of the frame synchronization signal of the reproduced data (L, R channels).

In the recording / reproducing apparatus, when recording data on the magneto-optical disk 1, an audio signal from, for example, a compact disk player, a tape player, or another mini disk player is supplied to the terminal 17a or 17b. Will be.

The terminal 17a is an input terminal for an analog signal. The recording signal (analog audio signal) supplied to the terminal 17a is converted into digital data by an A / D converter 18 and then converted into an encoder / decoder. 1
4 for audio compression encoding.

On the other hand, a terminal 17b is an input terminal for a digital signal, and audio information reproduced by an external compact disk player or mini-disc player is supplied in the form of digital data.
The data is supplied to the encoder / decoder unit 14 as recording data. This digital data includes not only voice information but also control data such as subcode information.

The recording data compressed in the encoder / decoder section 14 is once written in the buffer RAM 13 by the memory controller 12, read out at a predetermined timing, and sent to the encoder / decoder section 8. Then, after being subjected to encoding processing such as CIRC encoding and EFM modulation by the encoder / decoder section 8, it is supplied to the magnetic head drive circuit 15.

The magnetic head drive circuit 15 supplies a magnetic head drive signal to the magnetic head 6 according to the encoded recording data. That is, the magnetic head drive circuit 15
Drives the magnetic head 6 to form a modulation magnetic field, thereby applying a magnetic field of N or S pole to the magneto-optical disk 1. At this time, the system controller 11 supplies a control signal to the optical head 3 so as to output a laser beam at a recording level. Here, the encoder / decoder unit 1
4, when the digital data is inputted from the terminal 17b, for the management of the music to be recorded, and extracts the control data S _C in the digital data, and supplies to the system controller 11.

For example, digital data transmitted from a compact disk player or the like and input to the terminal 17b includes U-bit data, C-bit data, and V-bit data as control data in addition to audio information, as is well known. Exists.

The U bit data is called P, Q, R,
Sub-code data formed by S, T, U, V, and W data is included, and C-bit data includes category data, sampling frequency data, clock data, optical system data, and the like for determining a recording medium. Have been.
The V bit data includes an error flag and the like.

The system controller 11 manages various recording operations by using required data of the control data S _C , and performs recording based on Q data of U bit data as described later. Update the track number of the data that is The system controller 1
In 1, the source of input data is determined using V-bit data.

The structure of the Q data differs depending on various recording media. FIG. 2A shows the Q data structure of a compact disk, and FIG. 2B shows the Q data structure of a mini disk.

In the case of a compact disc, the Q data is
Following the control bit CTL and the address bit Ad, the track number TNO of the current music piece is indicated, followed by index information INDEX. Index information INDEX
Is information obtained by further subdividing the music, and the index information of the music of a certain track number is INDEX =
It can be subdivided from "01" to "99". Of course, if the song is not subdivided, INDEX = "01" to the end of the song
Is continuously attached. The index information is INDEX = “00” at the inter-song position (during pause) from the end of a certain song until the start of the next song.

Subsequently, the Q data is provided with elapsed time information (MIN, SEC, FRAME) in the music in minutes, seconds, and frames, further with absolute time information (AMIN, ASEC, AFRAME), and finally with a CRC. The code has been added.

In the case of the mini disc, the Q data includes a track number TNO, index information INDEX, and CR data.
A C code is provided, but no time information is added. However, as the index information INDEX, "01" to "99" indicating that playback is in progress, "00" indicating that pause is being performed, and "FF" indicating that playback is stopped exists as described above. I do.

Although the detailed operation will be described later, the system controller 11 performs such a Q operation in order to detect that all the music pieces that have been digitally input and recorded have ended.
Among the data, index information INDEX and elapsed time information (MIN, SEC, FRAME) in the music are used.

Further, in addition to such Q data, the system controller 11 controls the encoder / decoder 1
4 to detect the presence or absence of the audio data input thereto, and use this to detect the end of the supplied music.

In FIG. 1, reference numeral 19 denotes an operation input unit provided with keys for user operation, and reference numeral 20 denotes a display unit constituted by, for example, a liquid crystal display. The operation input unit 19 is provided with a recording key, a reproduction key, a stop key, an AMS key, a search key, and the like so as to be used by a user.

Reference numeral 21 denotes a RAM (hereinafter, referred to as a TOC memory) for holding TOC information in the magneto-optical disk 1. At the time when the magneto-optical disk 1 is loaded or immediately before the recording or reproducing operation, the system controller 11
The spindle motor 2 and the optical head 3 are driven, and the TOC set on the innermost side of the magneto-optical disk 1, for example, is set.
Extract area data. Then, the TOC information supplied to the memory controller 12 via the RF amplifier 7 and the encoder / decoder unit 8 is stored in the TOC memory 21. Thereafter, the system controller 11 uses the TOC information to control the recording / reproducing operation for the magneto-optical disk 1. The TOC information will be used.

In particular, in such a recordable disk medium, management data (user TOC data) for discriminating a recordable area or a recorded area is recorded. The contents can be rewritten in accordance with the erasure or erasure, so that recording can always be performed from a predetermined recordable area.

The processing of the system controller 11 for the recording stop control in the embodiment having such a configuration will be described with reference to the flowchart of FIG.

For the sake of explanation, in the recording / reproducing apparatus,
It is assumed that a compact disk player or a mini disk player exists as a source for supplying digital audio data to be recorded on the magneto-optical disk 1, and an analog audio signal is supplied from another source. Note that, for example, a DAT or the like can be considered as a digital signal source. However, when DAT is the source, the processing is the same as that for a compact disk, and therefore, the description is omitted.

At the time of recording, first, the system controller 1
1 determines whether the audio signal input for recording on the magneto-optical disk 1 is digital data or an analog signal. That is, it is determined which of the terminals 17a and 17b receives the audio data.

Although the detailed description is omitted for the case of analog input, even in this case, in order to automate the recording stop, there is no control data such as subcode in the analog audio signal, Detect the part,
For example, if the silent portion continues for a predetermined time or longer, it is determined that the supply of the audio signal from the source device has ended, and the recording may be stopped.

In the case of a digital input, the system controller 11 of the present embodiment performs the processing shown in FIG.

First, the system controller 11 proceeds from step SP1 to step SP2, detects category information from the C bit data transmitted together with the audio data, and determines whether the recording medium serving as a source is a compact disk or a mini disk. Is determined.

If the disc is a compact disc, the system controller 11 proceeds to step SP3. If the disc is a mini disc, the system controller 11 proceeds to step SP10.
And wait for a recording start operation.

Subsequently, when the compact disk is the source, the system controller 11 proceeds to step SP4 when the user starts a recording operation from the operation unit 19 in step SP3, and the supplied digital data is brought to an end state. Start monitoring.

That is, in step SP4, the system controller 11 first detects the elapsed time information (MIN, SEC) of the music in the Q data, and monitors a change in the elapsed time information. Here, when the change in the elapsed time information is no longer detected (in this case, the reproduction on the compact disk has been completed), the system controller 11 proceeds to step SP4 and determines whether or not audio data is actually supplied. Determine.

When the elapsed time information does not change and the audio data no longer exists, the system controller 11 can almost certainly detect that the compact disc player is in the reproduction end state. In this state, the system controller 11
Immediately without stopping the recording, the process proceeds to step SP6 and waits for n seconds (for example, about 10 seconds). It is confirmed that there is no change in the elapsed time information and no voice data exists during the standby. By setting the standby time in this manner, even if an operation such as track access on the compact disc player does not change the elapsed time information, and even if a state in which no audio data exists occurs, the state is regarded as the end of reproduction. Erroneous determination can be prevented.

After confirming that there is no change in elapsed time information and that there is no audio data during standby for n seconds, the system controller 11 determines that reproduction of the compact disk player has ended, and performs the recording / reproduction. Move on to the recording operation stop processing of the device.

That is, the system controller 11 proceeds to step SP7, and sets the time at which (n−α) is subtracted from the time (recording time position) at the time when the reproduction of the compact disc player is determined to be ended as the recording end time position. I do. That is, the system controller 11 writes, as the end address of the recorded music, the track address at a position obtained by subtracting (n-α) from the time position at which the reproduction is determined to be completed, to the user TOC. Here, α is set to, for example, about 1 second. Therefore, a position having a margin of about 1 second from the position where the change of the elapsed time information and the presence of the audio data disappears is set as the recording end position.

Subsequently, the system controller 11 proceeds to step SP18, and after actually stopping the recording operation,
Moving to step SP9, the processing procedure is completed.

According to such processing, even if the recordable capacity of the magneto-optical disc 1 is still sufficient, the recording / reproducing apparatus automatically performs the reproduction in response to the stop of the reproduction of the compact disc player as the source device. Thus, the recording operation is terminated, thereby preventing useless recording in a silent state.

Next, if the source is a mini disc,
In step SP10, the system controller 11 detects the recording start point, and in the following step SP11, monitors the index information INDEX in the Q data.

As described above, in the case of a mini-disc, the index information is any one of INDEX = “01” to “99” during reproduction, and INDEX = “00” during pause.
During playback stop, INDEX = "FF". Therefore, the system controller 11 can monitor the state where INDEX = “FF” and detect the stop of reproduction.

That is, the system controller 11 first monitors whether or not INDEX = “01” to “99” in step SP11.
To check if INDEX = “00”. INDEX =
When "00" is reached, that is, when the source side is in the pause state, the system controller 11 proceeds to step SP1.
In step 3, the recording operation of the recording / reproducing device is temporarily stopped. Then, the system controller 11 returns to step SP11 and sets INDEX = “01” to “9”.
9 ”, step SP14, step SP
Steps 15 and 16 are sequentially executed, and if the recording / reproducing apparatus is currently paused, this is released and the recording operation is started again.

It is needless to say that the recording corresponding to the source device can be temporarily stopped when the source is a compact disc.
As a process before step 4, index information detection processing may be performed to respond similarly. If the index information is "0
If it is not "1" to "99" or "00", the system controller 11 proceeds from step SP11 to step SP16.
Then, it is determined whether or not INDEX = “FF”. If INDEX = “FF”, the reproduction of the source mini-disc has been completed, and the system controller 11 stops recording on the mini-disc (magneto-optical disc 1) of the recording / reproducing apparatus. It will be the time when it is done. In this case, the recording end time position is
INDEX = time point when "FF" is detected.

However, in order to accurately detect the end of reproduction,
The standby process may be performed as in step F105 after the detection of INDEX = “FF”. In this case, the recording end time position is a time position (n-α) hours before the standby end time point.

By such processing, the recording / reproducing apparatus
As in the case where the source device is a compact disc player, the recording operation is automatically terminated when the reproduction of the mini-disc player as the source device is stopped, so that useless silent recording can be prevented.

Even if a digital input source other than a compact disk, a mini disk, and a DAT is conceivable, control data transmitted simultaneously or according to the format of control information added to the data. The stop of the reproduction on the source side may be detected using both the control data and the determination of the presence or absence of the audio data, and the recording end control may be executed.

According to the above arrangement, when music information is recorded in units of recording media from the audio device, when the reproduction of the audio device is completed, the recording can be automatically terminated, thereby simplifying the entire operation. can do.

(2) Second Embodiment By the way, if the performance selected by the user can be automatically recorded in units of one song, the usability of this kind of recording / reproducing apparatus can be improved and the convenience can be improved. It is considered to be.

For this reason, in the present embodiment, the system controller 11 executes the processing procedure shown in FIG. 4 to automatically record one song at a time.

That is, in the system controller 11, the process proceeds from step SP20 to step SP21.
Here, it is determined whether or not the operator for recording one music has been pressed. That is, in this embodiment, the magneto-optical disk device is provided with a normal recording operator and a one-track recording operator on the key 19, and when one of the one-track recording operator is depressed. Then, the process proceeds to step SP22, where it is determined whether or not the recording operator has been pressed.

Here, when the user operates the compact disc player to find the desired music, then presses the playback control, and then presses the recording control of the key 19, the system controller 11 Then, the process proceeds to step SP23, where a signal processing circuit such as the audio compression encoder / decoder 14, the memory controller 12,
The control data is sent to the servo circuit 9 and the like to switch the entire operation mode to the recording mode.

At this time, in the system controller 11, in the subsequent step SP24, the TOC memory 2
1 is accessed to detect a recordable area designated by a pointer (P-EMPTY), and based on the detection result, a start address A of the first part of the recordable area is set.

Subsequently, the system controller 11 proceeds to step SP25, in which a predetermined period of time has elapsed, and monitoring of control data output from the compact disk player is started, thereby starting detection of the beginning of the next music piece. Thereafter, the process moves to step SP27.

At this time, the system controller 11 starts monitoring the control data after a lapse of a predetermined period, so that the silent period immediately after the start of recording is not erroneously detected as a music interval. It is made to be able to detect the head of.

Here, the system controller 11 monitors the Q data of the control data and detects the index information to judge whether or not it is the head position of the following music. If a negative result is obtained, step SP26 is repeated. On the other hand, if the head of the following music piece is detected, the procedure moves to the next step SP27.

At this point, the system controller 11 detects the recording sector at the head position of the subsequent music piece detected at step SP26, and sets the sector recorded one sector before this sector as the end sector B.

Thus, the system controller 11
, Starting from a start address A, a link pointer is set as necessary, parts are sequentially specified, the last sector is set as an end sector B, and the TOC memory 2 is set.
Update 1

After the start address and the end address are set in this way, the system controller 11 proceeds to step SP28 to control the stop of the recording operation.
The UTOC of the magneto-optical disk 1 is updated with the contents of the TOC data memory 21 by rewriting the lead-in area of the TOC data memory 21, and this processing procedure ends in the next step SP30.

According to the configuration of FIG. 4, by stopping the recording operation based on the control data output from the digital audio device, the user does not have to confirm the end of the music and stop the recording operation each time. Can be automatically recorded in units of one song, and the usability of the recording / reproducing apparatus can be improved accordingly.

(3) Third Embodiment In this embodiment, the end of music is detected by detecting the signal level of audio information instead of the control data output from the digital audio device. As a result, the audio signal is recorded for each music piece and for each recording medium on the music source side.

That is, as shown in FIG. 5, when recording is started, the system controller 11 sequentially detects the signal level of the audio data, thereby detecting the time point t1 at which the signal level of the audio signal falls to the 0 level. When this signal level is maintained at 0 level for a predetermined period T1 from this time point t1, this time point t1 is determined as the end position of the performance selected by the user.

Thus, the system controller 11 sets the time point t2 after a predetermined period T2 has elapsed from the time point t1 as the end address of the performance and sets the UTOC.
To update.

In this way, the length of this period T1 can be selected to detect the interval between music pieces and the end of the recording medium when recording in units of music and when recording in units of recording media. This makes it possible to automatically execute the recording process when recording in units of one song and recording in units of recording media.

According to the configuration shown in FIG. 5, even if the end of the music is detected by detecting the signal level of the audio signal and the recording operation is controlled to be stopped based on the detection result, it is possible to further control the music one by one, A desired performance can be automatically recorded for each recording medium.
