Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus and a recording apparatus capable of recording or reproducing, for example, audio data on a recording medium having management information for managing recording / reproducing operations of data in track units. The present invention relates to a device, and particularly to a process of dividing (dividing) and combining tracks (combining).

[0002]

2. Description of the Related Art Data rewritable disc media on which a user can record music data and the like are known. In such disc media, an area in which data such as music has already been recorded and an unrecorded area have been recorded. (User TOC, hereinafter referred to as U-TOC) is provided, and this management data is rewritten each time an operation such as recording, editing, erasing, or the like is completed.

[0003] When recording a certain music, for example, the recording device searches for an unrecorded area on the disc from the U-TOC and records audio data there. . In the playback device, the area where the music (track) to be played is recorded is defined as U
Judgment is made from the TOC, the area is accessed, and the reproducing operation is performed.

Incidentally, in recordable disk media such as a magneto-optical disk (MO disk), DA
Random access is extremely easy as compared with a tape-shaped recording medium such as T or a compact cassette tape. Therefore, recording is performed in order from the first track to the n-th track from the inner circumference to the outer circumference on the disk. No need. That is, even if each music piece is physically recorded on the disc at a different position, the first track to the n-th track
As long as the recorded addresses of the songs up to the track are managed, the songs can be reproduced in the correct song order.

Further, for example, one track (music) does not necessarily need to be recorded on continuous parts (parts are parts where physically continuous data is recorded). There is no problem even if the data is discretely divided into a plurality of parts and recorded on the disc.

In particular, in a system in which data read from a magneto-optical disk is temporarily stored in a buffer RAM at a high rate, read from the buffer RAM at a low rate and demodulated as an audio reproduction signal, an access between parts is required. Thus, even if the data reading from the magneto-optical disk is temporarily interrupted, the reproduced sound can be output without interruption.

Therefore, if the recording / reproducing operation in the part and the high-speed access operation (access operation completed within the reproducible time due to the amount of data accumulated due to the difference between the write rate and the read rate of the buffer RAM) are repeated, 1
Even if the track of one music piece is divided into a plurality of parts and physically divided, the recording / reproduction of the music piece can be prevented.

For example, as shown in FIG. 17, the first music piece is continuously recorded as a part M ₁ and the second music piece is continuously recorded as a part M ₂ , but the fourth music piece and the fifth music piece are recorded as parts M _{4 (1) to} M _{4.
4 (4)} and M5 _{(1) to} M5 ₍₂₎ as shown in FIG. (Note that FIG. 17 is a schematic diagram to the last, and one part often covers several to several hundred tracks or more.)

When music recording and erasing are repeated on the magneto-optical disk, empty areas on the tracks are irregularly generated due to the difference between the playing time of the music to be recorded and the playing time of the erased music. Executing discrete recording in this manner makes it possible to record a song longer than the deleted song, for example, by utilizing the erased portion. The waste is eliminated. It should be noted that what is recorded is not limited to “songs”, but includes any signal if it is an audio signal. In this specification, a song is recorded as one unit of data (track) that is continuous in content. The description is made on the assumption that

Of course, for such a disc,
At the time of recording, recording must be continued while accessing a plurality of unrecorded parts, and at the time of reproduction, the parts must be accessed so that one music piece can be correctly and continuously reproduced. Data for connecting parts (for example, M4 _{(1) to} M4 ₍₄₎ ) in one music necessary for this and data indicating an unrecorded area are recorded or erased as described above. U-TOC rewritten for each operation
The information is held as information, and the recording / reproducing apparatus
By reading the TOC information and accessing the head, the recording / reproducing operation is controlled appropriately.

[0011]

As described above, the U-TOC which manages the addresses of the first to n-th tracks and the unrecorded area on the disk, and manages the connection of the parts and the connection of the unrecorded area in each track. In a system that performs recording / reproducing operations by referring to the disk device, editing such as division or connection of music (track) can be easily performed only by rewriting the U-TOC. For example, if a division (divide) operation is performed at a position in the middle of the first song, the address point is set as the end address of the first song, and a new point from that point to the end address that was originally the end address of the first song. By simply rewriting the U-TOC so as to be managed as the star address and end address of the second music generated in the above, the original first music is divided into the first music and the second music at an intermediate position. Will be. Also, the first
When a combining operation is performed at the boundary between the music piece and the second music piece, the start address and the end address of the second music piece are managed as the new start address and end address of the first music piece. If the U-TOC is rewritten as described above, the original first music piece and the second music piece are connected to form a new first music piece.

In order to perform such editing, in a conventional disk device, a reproduction mode (operation modes such as reproduction, reproduction pause, fast forward, fast rewind, and cueing) and a recording mode (operation modes such as recording and recording pause) are used. In addition, an edit mode operation function is added. The operation processing in the edit mode is as shown in FIG. For example, in playback mode
When the edit key is operated in (F900), (F901
→ YES), the operation in the edit mode is selected. Editing functions include combine, divide, and erase (the function of rewriting the U-TOC so that the specified track (song) is erased), title input (song name, disc name, etc. corresponding to the specified track (song) or disc) If there is a process of writing the character data into the U-TOC), it is determined in step F902, F903, F904, or F905 which process has been selected (entered), and the combine process (F906) is performed in response to the enter operation. , Divide processing (F907), erase processing (F908), and title input processing (F909).

However, even if an editing mode is prepared and various editing processes (U-TOC editing processes) can be executed as described above, there is a problem in that it is actually difficult for a user to use the functions. In particular, the usability is poor in combine processing and divide processing. For example, in the divide process that increments the track number,
Actually, it is preferable that the user can easily execute the program at a desired point during recording or reproduction. In other words, if divide processing (track marking) is performed when the speaker changes, such as when recording the contents of a meeting, the desired utterance can be made during playback without having to bother to divide the recording after the recording is completed. It can be accessed and played immediately. Similarly, when a radio broadcast is recorded, it is convenient at the time of reproduction if it is possible to quickly and easily perform track marking at the end of a song or the like. Further, even during reproduction or the like, it is convenient to be able to select an arbitrary point as it is while listening to the reproduced music or the like and perform track marking, or conversely, perform track marking off (that is, combine processing). However, since these processes are performed in the edit mode as described above, they cannot be easily performed during recording or playback.

[0014]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been made to enable divide processing and combine processing to be easily performed.

For this reason, a recording area in which a track as one data unit can be separated into one or a plurality of parts and which can be recorded discretely, a start address, an end address of the parts recorded in the recording area, and an inter-part A track mark operating means, for reproducing a predetermined track in the recording area on the recording medium, in a reproducing apparatus for reproducing a recording medium having a management area in which management information composed of link information for connecting the recording medium is recorded. Control means for rewriting the management information so that when the track mark operating means is operated during operation, the predetermined track is divided based on the address reproduced at that time. I do. Further, the control means, when dividing the predetermined track into a first track and a second track, uses the address reproduced when the track mark operating means is operated at the end of the first track. The management information is updated so that an address next to the address being reproduced when the track mark operating means is operated is set as a start address of the second track. further,
The disc player further includes a discriminating unit for discriminating whether or not the address being reproduced when the track mark operating unit is operated is a division point that has already been divided. When it is determined that the address being reproduced when the track mark operating means is operated is the division point, the division processing is not performed. The determination as to whether or not it is already a division point is based on management information,
This is performed based on the address being reproduced when the track mark operation means is operated.

Also, as a reproducing apparatus, a track mark operating means, a discriminating means for judging whether or not an address reproduced at the time of operating the track mark operating means is a track boundary position, If it is determined that the address being reproduced when the track mark operating means is operated is a track boundary position, the management is performed so that the tracks separated at the boundary position are combined. And control means for rewriting information. In this case, the combining process of the tracks separated at the boundary position updates the link information of the first track located before the boundary position to connect to the second track located behind the boundary position. To be done. Whether the address reproduced when the track mark operating means is operated is a track boundary position is determined by the management information recorded in the management area and the track mark operating means. The playback is performed based on the address that was being reproduced when the playback was performed.

The recording apparatus according to the present invention comprises a track mark operating means, and an address for the recording data at the time when the track mark operating means is operated during a recording operation of a predetermined track in the recording area on the recording medium. And control means for rewriting the management information so that the predetermined track is divided based on the control information. When dividing the predetermined track into a first track and a second track, the control unit sets an address for recording data when the track mark operation unit is operated as an end address of the first track. The management information is updated so that the next address of the address for the recording data when the track mark operating means is operated is set as the start address of the second track.

Further, these reproducing apparatus and recording apparatus can be connected to a headphone device or a microphone device, and the headphone device or the microphone device is provided with a track mark input means so that operation information can be input by the track mark input means. To

[0019]

A track mark operating means is provided to enable input or release of a track mark in a playback mode or a recording mode, that is, in an operation state such as during playback, recording, or pause, thereby providing divide editing. ,
The combine editing is easy to understand with a very simple operation, and is also useful as a function. further,
If a microphone device, a headphone device, or the like is provided with track mark input means so that divide editing and combine editing can be remotely controlled, operability and convenience are further improved as processing during recording and reproduction.

In FIG. 2, reference numeral 1 denotes a magneto-optical disk on which, for example, audio data is recorded, and schematically shows a state where the disk is loaded from the disk insertion unit 32. The magneto-optical disk 1 is driven to rotate by a spindle motor 2. Reference numeral 3 denotes an optical head for irradiating a laser beam to the magneto-optical disk 1 during recording / reproducing, which produces a high-level laser output for heating a recording track to the Curie temperature during recording, and uses a magnetic Kerr effect during reproduction. A relatively low level laser output for detecting data from the reflected light.

For this purpose, the optical head 3 is equipped with a laser diode as laser output means, an optical system including a polarizing beam splitter and an objective lens, and a detector for detecting reflected light. The objective lens 3a is held by the biaxial mechanism 4 so as to be displaceable in the radial direction of the disk and in the direction of coming into contact with and separating from the disk.

Reference numeral 6a denotes a magnetic head for applying a magnetic field modulated by the 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 entire optical head 3 and the magnetic head 6a can be moved in the disk radial direction by the thread mechanism 5.

The information detected by the optical head 3 from the magneto-optical disk 1 by the reproducing operation is supplied to the RF amplifier 7. The RF amplifier 7 performs a calculation process on the supplied information to reproduce RF signals, tracking error signals, focus error signals, absolute position information (absolute position information recorded as a pre-groove (wobbling groove) on the magneto-optical disk 1), The address information, the focus monitor signal, and the like are extracted. Then, the extracted reproduction RF signal is supplied to the encoder / decoder unit 8. Further, 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. Further, the absolute position information and the focus monitor signal are supplied to a system controller 11 constituted by a microcomputer, for example.

The servo circuit 9 generates various servo drive signals according to the supplied tracking error signal, focus error signal, track jump command and seek command from the system controller 11 and information on the rotational speed of the spindle motor 2. Shaft mechanism 4 and thread mechanism 5

After decoding processing such as EFM demodulation and CIRC in the buffer RAM 13
Is written to. Note that reading of data from the magneto-optical disk 1 by the optical head 3 and transfer of reproduced data in the system from the optical head 3 to the buffer RAM 13 are performed.
It is performed at 1.41 Mbit / sec and intermittently.

The data written in the buffer RAM 13 is read out at a timing when the transfer of the reproduction data becomes 0.3 Mbit / sec, and is supplied to the encoder / decoder section 14. Then, the digital signal is subjected to a reproduction signal process such as a decoding process for the audio compression process to be an output digital signal.

The output digital signal is converted into an analog signal by the D / A converter 15 and supplied to the output terminal 59 or the headphone output terminal 57 via the switch 16. Alternatively, the signal is directly supplied to the output terminal 59 without being converted into an analog signal. That is, the headphone 80 is connected to the headphone output terminal 57.

When an optical cable for audio is connected to the device, an audio signal is supplied to other devices as digital data.

Here, writing / reading of data to / from the buffer RAM 13 is performed by addressing the memory controller 12 under the control of a write pointer and a read pointer. The write pointer (write address) is as described above. As described above, the value is incremented at the timing of 1.41 Mbit / sec, while the read pointer (read address) is set to 0.3 Mbit / se.
Since the bit rate is incremented at the timing of c, the difference between the write and read bit rates causes the buffer RA
A certain amount of data is stored in M13.
When the full capacity data is accumulated in the buffer RAM 13, the increment of the write pointer is stopped, and the operation of reading data from the magneto-optical disk 1 by the optical head 3 is also stopped. However, since the read pointer R is continuously incremented, the reproduced audio output is not interrupted.

Thereafter, only the read operation from the buffer RAM 13 is continued, and at some point, the buffer RAM 13
If the amount of data stored in the memory becomes equal to or less than the predetermined amount, the data read operation by the optical head 3 and the increment of the write pointer are restarted again, and the data in the buffer RAM 13 is stored again.

By outputting the reproduced sound signal via the buffer RAM 13 in this manner, even if tracking is lost due to disturbance or the like, the output of the reproduced sound is not interrupted, and the data is stored. For example, by accessing the correct tracking position and restarting the data reading, the operation can be continued without affecting the reproduction output. That is, the vibration proof function can be significantly improved.

In FIG. 2, the address information output from the address decoder 10 and the subcode data used for the control operation are supplied to the system controller 11 via the encoder / decoder section 8 and used for various control operations. Further, the system controller 11 is also supplied with a lock detection signal of a PLL circuit for generating a bit clock for the recording / reproducing operation, and a monitor signal indicating a missing state of a frame synchronization signal of reproduced data (L and R channels).

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

When a recording operation is performed on the magneto-optical disk 1, an analog or digital audio signal is supplied from another device through an audio code or an audio optical cable connected to the input terminal 58. Alternatively, a microphone 70 is connected to the microphone input terminal 56 to supply an audio signal.

The audio signal sent to the input terminal 58 as digital data by the audio optical cable is directly supplied to the encoder / decoder section 14. The audio code or the analog audio signal input by the microphone 70 is transmitted through the switch 17 to the A / D converter 18.

The magnetic head drive circuit 6 supplies a magnetic head drive signal to the magnetic head 6a in accordance with the encoded recording data. That is, the application of the N or S magnetic field to the magneto-optical disk 1 by the magnetic head 6a is performed. At this time, the system controller 11 supplies a control signal to the optical head so as to output a laser beam at a recording level.

Reference numeral 19 denotes an operation input unit provided with keys used for user operations, and the above-mentioned switches 33 to 53 correspond to the switches or keys. The microphone 70 connected as described above has a track mark key 74
The operation information is obtained from the connector section 73 of the connection section 71, and the system controller 11 can detect the operation from the microphone input terminal 56. Similarly, the headphone 80 is also provided with operation keys 85 to 89, and these operation information is obtained from the connector 83 of the connection unit 81, and the system controller 11 can detect the operation from the headphone output terminal 57. It has been made possible.

The detection of operation information by the operation keys provided on the microphone 70 and the headphone 80 will be described with an example of the headphone 80. FIG. 6 shows a circuit configuration example of the headphone 80.

The connection section 81 has a stereo plug section 82 and a connector section 83. In the stereo plug section 82, the terminal 82a is an L channel audio signal, the terminal 82b is an R channel audio signal, and the terminal 82c is ground. Used respectively. The L and R audio signals connected to the headphone output terminal 57 of the recording / reproducing apparatus and supplied to the stereo plug unit 82 are changed by a variable resistance unit 84 that is changed by a volume adjustment knob 84.
The audio signal is supplied to the ear speaker unit via a and output as audio.

On the other hand, in the connector section 83, the terminal 8
3a is for + B voltage, terminal 83b is for data, terminal 83c is for input, and terminal 83d is for clock. And

Therefore, on the system controller 11 side of the recording / reproducing apparatus, if the voltage value at the input terminal 83c is detected, the operation contents of each of the keys 85 to 89 on the headphone 80 can be determined. Play,
Operations such as stopping can be performed. Microphone 70
The same applies to the track mark key 7
If the voltage state by the resistance division changes according to the operation of No. 4, the operation can be detected by the system controller 11.

Also, as shown in FIG.
When an infrared command signal is received from the remote commander 90, the infrared command signal is converted into an electric signal and supplied as a command pulse to the system controller 11, and the system controller 11 performs various processes based on the command pulse. By doing so, remote operation by the remote commander 90 is enabled.

When recording / reproducing operations are performed on the disc 1, management information recorded on the disc 1, that is, P-TOC (pre-mastered TOC), U-
By reading out the TOC (user TOC), the system controller 11 determines the address of the part to be recorded on the disk 1 and the address of the part to be reproduced on the disc 1 according to the management information. The data is held in the buffer RAM 13. Buffer RAM
Reference numeral 13 designates a buffer area for the recording data / reproduction data and an area for holding the management information.

Then, the system controller 11 reads out the management information by executing the reproducing operation on the innermost side of the disk on which the management information is recorded when the disk 1 is loaded, and stores it in the buffer RAM 13. In advance, the information can be referred to at the time of the recording / reproducing operation for the disc 1.

The U-TOC is edited and rewritten in accordance with recording or erasing of data. The system controller 11 performs this editing process every time a recording / erasing operation is performed. The rewriting operation is performed on the TOC information, and the U-TOC area of the disc 1 is also rewritten at a predetermined timing in accordance with the rewriting operation.

<2. P-TOC Sector> Here, the P-TOC sector will be described first as audio data sectors recorded on the disk 1 in the form of sector data and management information for managing recording / reproducing operations of audio data. As the P-TOC information, designation of an area such as a recordable area (recordable user area) of the disc, management of a U-TOC area, and the like are performed. When the disc 1 is a pre-mastered disc which is a read-only optical disc, it is also possible to manage music recorded in a ROM by the P-TOC.

FIG. 7 shows the format of the P-TOC.
FIG. 7 shows a P-TOC repeatedly recorded in an area used for P-TOC (for example, a ROM area on the innermost peripheral side of the disk).
One sector (sector 0) of the TOC information is shown. The P-TOC format is optional for sectors 1 and subsequent.

The data area of the P-TOC sector (4 bytes × 588, 2352 bytes) has all 0s at the head position.
Alternatively, a synchronization pattern consisting of all-one 1-byte data and an address indicating a cluster address and a sector address are added by 4 bytes, and the above is used as a header to indicate that the area is a P-TOC area.

Following the header, an identification ID in ASCII code corresponding to the character "MINI" is added at a predetermined address position. In addition, followed by disk type and recording level, the track number of the first piece of music that has been recorded (First TNO), the track number of the last piece of music (Last TNO), the read-out start address RO _A, power cal area start address PC _A , U-TOC (U of FIG. 8 described later)
_-A start address UST _A of a data area of TOC sector 0, a start address RST _A of a recordable area (recordable user area), and the like are recorded.

Subsequently, there is provided a correspondence table instruction data section having table pointers (P-TNO1 to P-TNO255) for associating each recorded music or the like with a parts table in a management table section described later.

In the area following the corresponding table instruction data section, (01h) to (FF) corresponding to the table pointers (P-TNO1 to P-TNO255) in the corresponding table instruction data section.
A management table section provided with 255 parts tables up to h) is prepared (note that “h” in this specification).
The numerical value marked with is in a so-called hexadecimal notation). Each part table has a start address as a starting point, an end address as an end for a certain part,
Also, mode information (track mode) of the part (track) can be recorded.

The track mode information in each part table records, for example, whether or not the part is set to prohibit overwriting or data copying, whether or not it is audio information, the type of monaural / stereo, and the like. Have been.

Each part table from (01h) to (FFh) in the management table section indicates the contents of the part by the table pointer (P-TNO1 to P-TNO255) of the corresponding table instruction data section. In other words, for the first song, a part table (for example, (01h)) is used as the table pointer P-TNO1. However, the table pointer is actually a byte position in the P-TOC sector 0 by a predetermined calculation process. In this case, the start address of the parts table (01h) is the start address of the recording position of the first music piece, and the end address is the same as the end address of the first music piece. The end address of the position where the first song is recorded. Further, the track mode information is information on the first music piece.

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

In the case of a recordable / reproducible magneto-optical disk, since there is no so-called premastered music area, the above-described correspondence table instruction data section and management table section are not used (these are referred to as U-recording sections). TO
C), so that each byte is set to "00h". However, for a pre-mastered type disc in which all songs are recorded in a ROM form (pit form) and a hybrid type disc having both a ROM area and a magneto-optical area as an area for recording songs and the like, The correspondence table instruction data section and the management table section are used for managing the music in the ROM area.

<3. U-TOC sector> followed by U-T
The OC will be described. FIG. 8 shows the format of one sector (sector 0) of the U-TOC, in which management information mainly on the music that the user has recorded and on the unrecorded area (free area) where new music can be recorded is recorded. Data area. Note that the U-TOC is also optional for sector 1 and subsequent sectors. For example, disk 1
When a certain music piece is to be recorded, the system controller 11 searches for a free area on the disc from the U-TOC and can record audio data there. At the time of reproduction, the area in which the music to be reproduced is recorded is determined from the U-TOC, and the reproduction operation is performed by accessing the area.

In the U-TOC sector (sector 0) shown in FIG. 8, a header is first provided in the same manner as in the P-TOC, and then a maker code, a model code, a music number of the first music are provided at a predetermined address position. (First TNO), the last song number (Last TNO), sector usage status, disk serial number, disk ID, etc., are recorded. Various table pointers (P-DFA, P-EMPTY, P-EMPTY,
An area for recording FRA, P-TNO1 to P-TNO255) is prepared.

Then, 255 parts tables (01h) to (FFh) are provided as a management table section to be associated with the table pointers (P-DFA to P-TNO255) of the corresponding table instruction data section. 7, a start address as a starting point, an end address as an end, and mode information (track mode) of the part are recorded in the same manner as the P-TOC sector 0 in FIG. In the case of this U-TOC sector 0, since the parts indicated in each part table may be successively connected to other parts, the part table in which the start address and the end address of the connected parts are recorded is stored. The link information shown can be recorded.

In this type of recording / reproducing apparatus, as described above, even if data of one music piece is physically discontinuous, that is, even if it is recorded over a plurality of parts, it is reproduced while accessing between parts. Since there is no hindrance to the reproduction operation, the music or the like recorded by the user may be recorded in a plurality of parts for the purpose of efficient use of the recordable area. Therefore, link information is provided,
For example, the numbers (01h) to (F
Fh) (actually indicated by a numerical value indicating a byte position in U-TOC sector 0 by a predetermined arithmetic processing), the part tables can be connected by designating the part tables to be connected. .
(Note that music and the like recorded in a pit form in advance are not usually divided into parts,
In the P-TOC sector 0, the link information is all "(00h)". )

That is, in the management table section in the U-TOC sector 0, one part table represents one part, and for example, music composed of three connected parts is connected by link information. The parts positions are managed by the three parts tables.

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

The table pointer P-DFA is shown for a defective area on the magneto-optical disk 1, and is a single part table or a plurality of parts tables indicating a track portion (= part) which becomes a defective area due to a scratch or the like. The first part table in the box is specified. In other words, when a defective part exists, (01) is set in the table pointer P-DFA.
h) to (FFh) are recorded, and in the corresponding parts table, defective parts are indicated by start and end addresses. If another defective part exists, another part table is designated as link information in the part table, and the defective part is also shown in the part table. If there is no other defective part, the link information is set to, for example, "(00h)", and there is no link thereafter.

The table pointer P-EMPTY indicates the head part table of one or a plurality of unused part tables in the management table section. If there is an unused part table, the table pointer P-EMPTY is set as the table pointer P-EMPTY. , (01h) to (FFh) are recorded.
If there are multiple unused part tables, the part table specified by the table pointer P-EMPTY is sequentially specified by link information, and all unused part tables are connected on the management table section Is done.

The table pointer P-FRA indicates a writable free area (including an erasing area) on the magneto-optical disk 1 and a track area (= part) indicating a free area track portion (= part). The first part table in multiple parts tables is specified. That is,
Table pointer P-FRA if free area exists
, Any one of (01h) to (FFh) is recorded.
In the corresponding parts table, parts as free areas are indicated by start and end addresses. Also, if there are a plurality of such parts, that is, if there are a plurality of parts tables,
The link information is sequentially specified up to the parts table where "(00h)" is displayed.

FIG. 9 schematically shows the management state of parts that are free areas by using a parts table. This is because when the part (03h) (18h) (1Fh) (2Bh) (E3h) is set as a free area, this state follows the corresponding table instruction data P-FRA and the parts table (03h) (18h) (1Fh) The state represented by the link of (2Bh) (E3h) is shown. It should be noted that the above-described management of the defective area and the unused parts table is the same.

By the way, if it is a magneto-optical disk on which no audio data such as music has been recorded and there is no defect,
Parts table (01h) by table pointer P-FRA
This indicates that the entire recordable user area of the disc is an unrecorded area (free area). And, in this case, it remains (02h)-(FFh)
Because the parts table of is not used,
The parts table (02h) is specified by the table pointer P-EMPTY, the parts table (03h) is specified as the link information of the parts table (02h), and the part table (03h) is specified as the link information of the part table (03h).
(04h) is specified, and the parts table (FFh)
Is linked to In this case, the link information of the parts table (FFh) is set to "(00h)" indicating that there is no connection thereafter. At this time, in the parts table (01h), the start address of the recordable user area is recorded as the start address, and the address immediately before the lead-out start address is recorded as the end address.

The table pointers P-TNO1 to P-TNO255 indicate music recorded by the user on the magneto-optical disk 1. For example, the table pointer P-TNO1 includes one or a plurality of pieces of data on which data of the first music is recorded. A parts table indicating a temporally leading part of the parts is designated.

For example, when the first music piece is recorded on the disk without dividing the track (that is, as one part), the recording area of the first music piece is the part indicated by the table pointer P-TNO1. It is recorded as a start and end address in the table.

Further, for example, when the second music piece is discretely recorded on a plurality of parts on the disc,
Each part is designated in order of time to indicate the recording position of the music. That is, the table pointer P-TNO2
The other part tables are sequentially specified in order from the part table designated by the link information according to the link information, and linked to the part table where the link information becomes "(00h)" (similar to FIG. 9 described above). Form). In this way, for example, since all the parts on which the data constituting the second tune are recorded are sequentially designated and recorded, the data of the U-TOC sector 0 can be used to reproduce the second tune or the second tune. When performing overwriting on the area, it is possible to access the optical head 3 and the magnetic head 6a to extract continuous music information from discrete parts, and to perform recording using the recording area efficiently.

As described above, the area management on the disk is P
-Music performed by the TOC and recorded in the recordable user area, free areas, etc.
Performed by OC. The TOC information is read into the buffer RAM 13 so that the system controller 11 can refer to it.

<4. Area structure of disk> Here, the area structure of the disk will be described. FIG. 10A schematically shows the area structure of a disk in the radial direction. In the case of a magneto-optical disk, FIG.
As shown in (a) as a pit area, an area in which data is recorded by embossed pits (a pre-mastered area) and a so-called magneto-optical area which is provided with a groove are divided.

Here, the pit area is the P-
The TOC is repeatedly recorded. As described above, the position of the U-TOC is indicated as the U-TOC start address UST _A in the P-TOC, and the lead-out start address RO _A and the recordable user area start address Each address position shown in FIG. 10A is shown, such as RST _A , power cal area start address PC _{A and the} like.

[0082] While the groove area following the pit area on the innermost circumference side of the disk is formed, the area up to the address shown as the read-out start address RO _A within the P-TOC out of the groove area, It is a recordable area that can be recorded, and is hereinafter referred to as a lead-out area.

Further, of the recordable areas, the recordable user area in which data is actually recorded is a recordable user area start address RS
From T _A, the up position of the lead-out start address RO _A just before.

[0084] Then, the area to be pre-recordable user area start address RST _A within the groove area is a management area for recording and reproducing operations, U-TOC or the like as described above is recorded, also power cal area start One cluster from the position indicated by the address PC _A is provided as a laser power calibration area.

The U-TOC has a U-TOC start address UST in the management area for this recording / reproducing operation.
Three clusters (1 cluster = 36 sectors) are continuously recorded from the position indicated by _A.

The actual voice data is, for example, as shown in FIG.
As shown in (a), it is recorded in the recordable user area. For example, in this case, the music M ₁ ~M ₄ four tracks, the address A ₂₀ to A of the first piece of music to ₂₁ parts of the music M ₁
There are recorded, also music M ₂ of the second track address A ₂₂ ~
Portion M _{2 (1)} address A ₂₆ recorded in parts A ₂₃ ~
Is divided into a portion M ₂ that has been recorded in parts of the A _{27 (2)} have been recorded. In addition, the music M ₃ of the third song the address A ₂₄ ~
Are recorded in parts A _25, the music M ₄ of the fourth piece of music is recorded in the part of the address A ₂₈ to A _29. In this state,
Address A is a free area where no music is recorded
The ₃₀ ~A ₃₁ parts. For example, such a recording state is managed in the U-TOC by the table pointers P-TNO1 to P-TNO4, P-FRA, and the parts table connected thereto, as described above. FIG. 11 shows the management state in this case. If there is no defect in the recordable user area in FIG. 10A, the table pointer P-DFA is set to “00h”.

The table pointer P-FRA manages an unrecorded area (free area). For example, in this case, if the table pointer P-FRA indicates a parts table (06h), the table pointer P-FRA corresponds to this. The parts table (06h) shows information on parts that are free areas in FIG. 10A. That is, address A
Reference numeral ₃₀ denotes a start address, and address A ₃₁ denotes an end address. In this case, since there is no free area as another part, the parts table (06)
The link information of h) is "00h".

[0088] The first its start address A ₂₀ and end addresses in the part table of shown in the table pointer P-TNO1 for music M ₁ (01h) A ₂₁
Is shown. For music M ₁ is recorded on the one part, the link information of the parts table (01h) "00
h].

[0089] For the second music M _2, the start address A ₂₂ and an end address A ₂₃ at the parts table indicated by the table pointer P-TNO2 (02h) is shown. However music M ₂ is two parts _(M 2 ₍₁₎
And M _{2 (2)} ), and the addresses A ₂₂ and A ₂₃ only indicate parts of the first half (M _{2 (1)} ) of the music M ₂ . Therefore, for example, a part table (03h) is shown as link information of the part table (02h), and the part table (03h) has a start address A ₂₆ to indicate parts of the latter half (M _{2 (2)} ).
And the end address A ₂₇ are recorded. Since the link is unnecessary thereafter, the link information of the parts table (03h) is set to "00h".

The parts positions of the third music piece M ₃ and the fourth music piece M ₄ are managed by part tables obtained from the table pointers P-TNO3 and P-TNO4, respectively. Since only four songs have been recorded, the table pointers P-TNO5 to P-TNO255 are not used and are set to "00h". A table pointer P-EMPTY indicating an unused parts table indicates the parts table (07h) in this case, and all unused parts tables from the parts table (07h) to the parts table (FFh) are displayed. Linked by link information.

<5. Divide and Combine Editing Process> As described above, each song (track) is managed by the U-TOC, and the recording / reproducing operation is performed based on this, so that the song is divided (divided) only by rewriting the U-TOC. Music can be connected (combined).

Hereinafter, the operation and the processing for editing the byte / combine in this embodiment will be described with reference to FIGS. As described above, the recording / reproducing apparatus main body 30
Are provided with a mark-on key 46 and a mark-off key 47 as track mark keys, and the remote commander 90 is also provided with a mark-on key 95 and a mark-off key 96. Further, the microphone 70 is provided with a track mark key 74,
Also, a track mark key 89 is provided. The track mark keys 74 and 89 are operation keys that serve both as a mark-on key and a mark-off key.

The operation information from these operation keys is supplied to the system controller 11 as described above, and the system controller 11 operates the mark-on keys 46, 9 on the recording / reproducing apparatus main body 30 or the remote commander 90.
For the operation input of No. 5, the process of FIG. 14 is performed to perform the divide process.

In FIG. 14, step F100 indicates a case where the system controller 11 is controlling the reproducing operation in the reproducing mode, controlling the reproducing pause operation, or controlling the recording operation in the recording mode. ing. When a recording pause operation is performed in the recording mode, the track number is automatically incremented at that point (that is, divide processing is performed). In this case, even if the user performs the divide operation, Since it is unnecessary, the system controller 11 ignores the operation information.

When the user operates the mark-on key 46 or 95 while the system controller 11 performs the reproduction, the reproduction pause, or the recording process and the recording / reproduction device performs the reproduction operation, the reproduction pause operation, or the recording operation. Then, the process proceeds from step F101 to F103. Then, it is determined whether the address of the playback or recording progress point at that time or the address of the point where the playback pause is being executed is a break in the music, that is, whether or not the address is already a divide point. This determination can be made based on whether or not the address at that time matches or is very close to the start address or end address of each music piece.

Then, if a negative result is obtained in step F103, that is, since the music piece is located in the middle of a certain music piece, divide processing is started (F104). Note that, during recording, normally, the position at the time of the divide operation does not always become the track change point that has already been divided, so that the processing of step F103 is not particularly necessary.

In the divide process in step F104, a process of rewriting the U-TOC data read into the buffer RAM 13 and a display of the divide operation are performed.
The display at this time includes displaying a message indicating the execution of the divide, changing the displayed track number, resetting the display of the music progress time to zero, and the like.

Actual divide processing, that is, U-TOC
Is rewritten as follows. Now, for example by reproducing operation, when the reproduction of the middle portion of the music M ₃ shown as TM _ON in FIG. 10 (a) have been made, the user presses the mark-on key 46. Then, the divide processing in step F 104, the music M ₃ are 10
(B), the will be divided into music M ₃ and music M ₄ that address point as a boundary. At this time,
The music M4 in FIG. 10A originally recorded as the _fourth music is changed to the fifth music M as shown in FIG. 10B.
It will be ₅ .

In this case, the U-TOC is rewritten from the state of FIG. 11 as shown in FIG. 12 (the rewritten portion is indicated by oblique lines). That part table table pointer P-TNO3 had shown (04h) is, A ₂₄ as the start address, but A ₂₅ as the end address is recorded, the address at the time of divide operation is to have been A _32, which is new since the end address of the music piece M _3, the end address of the part table (04h) is rewritten from a ₂₅ to a _32. Also, originally the fourth
Because music M ₄ was music is composed uplink fifth music track number repeated by divide process, it numbers had Kakare the table pointer P-TNO4 to is written in the table pointer P-TNO5, the table pointer P- TNO5 shows a parts table (05h). In other words, parts of A ₂₈ to A ₂₉ that were indicated as the start and end addresses in the part table (05h) is newly managed as a fifth music M _5.

Then, new data generated by the divide processing is generated.
I didn't use the 4th song before
It is represented by a parts table (07h). That is,
In the parts table (07h), as the start address
Divide point address A ₃₂A which is the next address of
₃₃Is written, and the end address is originally the third
End address of the song and the parts table (04h)
A that was being shy_{twenty five}Is written. And the table
Pointer P-TNO4 points to parts table (07h)
Can be rewritten as

Since the parts table (07h) is used for the management of the new fourth music piece, this parts table (07h) is removed from the link structure of the table pointer P-EMPTY, and the table pointer P-EMPTY is It is rewritten as shown in the table (08h). The link information of the parts table (07h) is rewritten to "00h".

[0102] Through the above rewriting, divide is complete, then the music M ₃ are A ₂₄ to A _32, the music M ₄ is A ₃₃ to A
_25, the music M ₅ will be managed as A ₂₈ to A _29. In other words, in this embodiment, during playback, during playback pause, and during recording, the user can perform divide editing only by pressing the mark-on key 46 or 95 at a required timing. Thereafter, if a stop operation is performed, the playback, playback pause, or recording operation is terminated (step F102 → YE
S) At that time, the U-TOC stored in the buffer RAM 13 at that time is actually
The area is written (F105), and the operation is stopped (F106).

As for the processing when the mark-off keys 47 and 96 of the recording / reproducing apparatus main body 30 or the remote commander 90 are input to the system controller 11, the combine processing is performed as shown in FIG.

In FIG. 15, step F200 indicates a case where the system controller 11 is controlling the reproduction operation in the reproduction mode or controlling the reproduction pause operation. Since no combine operation is performed during the recording mode, the operation input of the mark-off keys 47 and 96 is ignored during the recording mode.

If the user operates the mark-off key 47 or 96 while the system controller 11 performs playback or playback pause processing and the recording / playback apparatus is performing playback operation or playback pause operation, the processing proceeds as follows. The process proceeds from step F201 to F203. In this case as well, it is determined whether the address of the reproduction progress point or the address of the point where the reproduction pause is being executed at that time is a break in the music, that is, whether or not the address is already a divide point.

Then, if a positive result is obtained in step F203, that is, since it is the divide position of the break of a certain music (track), the divide state is canceled and the combine processing for connecting the music is started (F204).

In the combine process in step F204, a process of rewriting the U-TOC data read into the buffer RAM 13 and a display of the combine operation are performed.
At this time, a message indicating the execution of the combine, a change of the track number displayed subsequently, an advance of the music progress time due to the connection of the music, and the like are performed.

Actual combine processing, that is, U-TOC
Is rewritten as follows. For example, in the state of the divide processing as described above is made FIG. 10 (b), the by the playback operation, the playback end portions of the music M ₂ shown as TM _OFF (near the end address of the part M _{2 (2))} is performed At this point, the user presses the mark-off key 47
Suppose you press. Then, the combined process of step F 204, so that the music M ₂ and the music M ₃ is connected as shown in Figure 10 (c). At this time, the tunes M ₄ and M ₅ in FIG. 10B, which were set to the fourth tune and the fifth tune before the combine operation, are combined with the third tune to the second tune and incorporated in FIG. new third track as (c), the is the fourth piece of music M _3, M _4.

In this case, the U-TOC is rewritten from the state shown in FIG. 12 as shown in FIG. 13 (the rewritten portion is indicated by oblique lines). That table pointer P-TNO3 indicates they were part table (04h) is, A ₂₄ as a third start address of music M _3, but A ₂₅ as the end address is recorded, part of the third track and the second The part table (04h) is incorporated in the link starting from the table pointer P-TNO2 to be incorporated into the music piece.
That link information of the parts table that represented of the part M _{2 (2)} music M ₂ (03h) is set to "04h", therefore the table pointer P-TNO2 from the parts table (02
A link structure of h) → (03h) → (04h) is formed. Thus, second music and the third track is managed by being connected as a new piece of music M _2.

[0110] Further, since the fourth music M ₄ was music in FIG. 10 (b) serving as the third track down track number repeated by combined treatment table pointer until it P-
The numerical value written on TNO4 is written to the table pointer P-TNO3, and the parts table (07h) is indicated on the table pointer P-TNO3. That is, the parts table (0
Part A ₃₃ to A ₂₅ that were indicated as the start address and the end address to 7h) is newly managed as a third music M _3.

[0111] Similarly, the music M ₅ was 5 music in FIG. 10 (b) to be lowered fourth music track number repeated by combined treatment table pointer until it
The value written on P-TNO5 is replaced by the table pointer P-TNO4
And the part table (05h) is indicated in the table pointer P-TNO4. That is, the part of A ₂₈ to A ₂₉ that were indicated as the start and end addresses in the part table (05h) is newly 4th music M
Managed as ₄ . Then, since the fifth music piece is lost, the table pointer P-TNO5 is set to "00h".

[0112] Through the above rewriting, combine is complete, then the music M ₂ is A ₂₂ to A ₂₃ and A ₂₆ to A ₂₇ and A ₂₄ ~
Three parts of A ₃₂ is managed as being recorded by _{(M 2 (1), M} 2 (2), M 2 (3)), also, the music M ₃ are A ₃₃
To A _25, the music M ₄ will be managed as A ₂₈ to A _29.

That is, in this embodiment, during reproduction or during reproduction pause, the user can perform combine editing only by pressing the mark-off key 47 or 96 at a required timing. Thereafter, when a stop operation is performed, the playback or the playback pause operation is terminated (step F202 → YES),
At this time, the U-TOC stored in the buffer RAM 13 at that time is actually written in the U-TOC area of the disk 1 (F205), and the operation is stopped (F206).

In the present embodiment, the microphone 70
And the headphone 80 also has the track mark keys 74, 89.
Divide and combine edits can be performed in the same manner, but the track mark keys 74 and 89 are also used as a mark-on key and a mark-off key. By using a single key, the arrangement of the microphone and the headphone does not cause much obstacle in terms of arrangement space, and it is suitable without disturbing use.

Regarding the operation input by the track mark keys 74 and 89, the key is also used for the mark-on / mark-off operation.
Executes the divide / combine by the processing of FIG.

In FIG. 16, step F300 indicates a case where the system controller 11 controls the reproducing operation in the reproducing mode, controls the reproducing pause operation, or controls the recording operation in the recording mode. ing.

With respect to the operation of the track mark keys 74 or 89, the divide operation as a mark-on key is executed during reproduction or recording, or during a playback pause operation at a position other than the beginning of the music, and a pause is made at the beginning of the music. If the track mark key 74 or 89 is operated during the operation, it is determined that the operation is a combine operation as a mark-off key.

During the playback pause, the user presses the AMS key (AMS key 39 on the main unit, AMS key 8 on the headphones).
Assuming that the head of the music has been operated using 7, 88, or the AMS key of the remote commander 90), the process proceeds from step F301 to F304. Then, a track access as a cueing operation is performed, and a reproduction pause state at the beginning of the music piece is set. At this time, if the playback operation / recording operation is performed, the process returns to step F300, and the required processing is performed.
(F306 → F300), and if a stop operation is performed, stop processing starts (F307 → F311). However, when the playback is paused at such a tune start position, the track mark key 7
If operation 4 or 89 has been performed, the process proceeds to step
The process proceeds from F305 to F308 to perform a combine process. In other words, since it is in the playback pause state at the beginning of the song, that point is always a divide point,
The user does not need to divide. Therefore, it is determined that this is a combine operation, and the U-TOC is rewritten so that combine edit is performed as described above.

If the track mark key 74 or 89 is operated in the playback / playback pause / recording state, the process proceeds from step F302 to F309. Then, it is determined whether the address of the playback or recording progress point at that time or the address of the point where the playback pause is being executed is a break in the music, that is, whether or not the address is already a divide point.

If a negative result is obtained in step F309, that is, since the position is in the middle of a certain music piece, it is determined that the user's operation is a divide operation, and as described above, the U-edit as divide edit is performed. Divide processing for rewriting the TOC is started (F310).

When the stop operation is performed, the playback or the playback pause or the recording operation is terminated (step F303 → YES or
F307 → YES) At that time, the buffer RAM1
The U-TOC stored in disk 3 is actually
-Write to the TOC area (F311) and stop the operation (F3
312).

By the above processing, the divide / combine processing can be performed by the track mark keys 74 and 89 which are also used for the mark on / mark off.

As described above, in this embodiment, the track mark keys 74 and 8 are set during playback, playback pause, and recording.
9 or the mark-on keys 46 and 95 or the mark-off keys 47 and 96, the desired divide or combine editing is performed, and there is no need to operate after switching to the edit mode. Will be good. In particular, by performing track marking while performing recording and playback, not only editing operations but also usability during subsequent playback is greatly improved. Also, recording,
By realizing the operation of dividing / connecting a track at a desired point during reproduction, the user can easily understand the divide / combine editing.

Further, since the divide / combine operation can be performed in the remote commander 90, the headphone 80, and the microphone 70, editing can be performed more easily as needed. In particular, by providing the microphone 70, an operation such as performing a track marking every time a speaker changes using a microphone installed on a desk at the time of recording a conference or the like can be easily realized.

Incidentally, the operation for dividing / combining editing of the present invention and the processing corresponding thereto can be variously changed in addition to the embodiment. For example, the recording / reproducing apparatus main body 30 and the remote commander 90 may be provided with a track mark key that also serves as a mark-on / mark-off. Conversely, a mark-on key and a mark-off key may be separately provided on the microphone 70 or the headphone 80. It may be provided. Further, a track mark operating means and a mark on / mark off operating means may be provided in another connected device.
