Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a recording medium such as a magneto-optical disk, for example. In particular, the management information is updated by updating the management information corresponding to the recording medium in which the reproduction order of the predetermined unit recording data is managed by the management information. The present invention relates to an editing apparatus for editing unit recording data.
[0002]
[Prior art]
Various recording media and recording / reproducing apparatuses corresponding to them have been developed. In particular, as known as a mini-disc system in recent years, ones in which a user can freely record music data and the like have become widespread.
[0003]
For example, in the case of this mini-disc system, in order to manage the area where the user recorded on the disk (data recorded area) and the area where nothing has been recorded yet (data unrecorded area), Apart from main data such as music, management information called user TOC (hereinafter referred to as U-TOC) is recorded. The recording device discriminates an area for recording while referring to the U-TOC, and the reproducing device discriminates an area to be reproduced with reference to the U-TOC.
[0004]
That is, in the U-TOC, each recorded music or the like is managed in a data unit called a track, and its start address, end address, etc. are recorded. An unrecorded area (free area) where nothing is recorded has its start address, end address, etc. recorded as a data recordable area.
Further, by managing the area on the disc by such a U-TOC, only by updating the U-TOC, the track is divided (divided) and connected (combined) as a unit of recording data such as music. Editing processing such as movement (move: change of track number) can be performed easily and quickly.
Then, by utilizing such a function, the user can edit one or a plurality of tracks once recorded on the disc to create and enjoy a personal original disc.
[0005]
[Problems to be solved by the invention]
However, as a conventional combine editing process, for example, it is possible to connect only tracks having continuous track numbers assigned to the respective tracks. For this reason, in order to perform combine editing for a plurality of tracks whose track numbers are not continuous, first, edit the track numbers of the tracks to be combined by using a move editing function, etc. After that, it is necessary to connect a plurality of tracks by a combine editing process.
[0006]
In addition, in the combine editing process, the order in which the tracks to be connected in the playback time axis are connected in accordance with the track number order, and the track numbers set for the tracks formed by the connection are connected. The track number is the smallest of the plurality of track numbers.
For this reason, for example, when performing a combine editing operation in a plurality of tracks to be connected in such a way that the track with the larger track number is placed in the connecting order before the track with the smaller track number, the user performs the combine editing. Prior to this, it is necessary to move the music order by using move editing or the like while considering the connection order of the target tracks.
Also, if you want to set the track number of the connected track to a different track number that is different from the track number that is automatically set after the combine process, you can perform the move edit operation again after the combine edit. It is necessary to move the music order so that the track number desired by the user is obtained.
[0007]
In this way, when editing tracks such as the above, and the accompanying track number settings, etc., the current combine editing function is not sufficient, and other types of editing functions are available. Therefore, there is a problem that the user is forced to perform a complicated editing operation.
[0008]
[Means for Solving the Problems]
Accordingly, in consideration of the above-described problems, the present invention enables a combination of a plurality of tracks with discontinuous track numbers as a combination editing process, and at this time, regarding the setting of the track numbers of the connected tracks. The purpose is to enhance the editing function of the combine.
[0009]
  Therefore, audio data is recorded in units of tracks, and management information update processing for at least units of tracks is executed in correspondence with a recording medium on which management information for managing audio data recording / playback operations is recorded. As a possible editing device, a designation operation means capable of designating a track number of a plurality of tracks in an arbitrary order and a track of a track number designated by the designation operation means are connected in accordance with the designation order to form one track. And a track number corresponding to one connected track formed as a result of the connection.Join processThe management information update control means for updating the management information by setting as described above is provided.
[0010]
Further, the management information update means sets the track number of the track having the smallest track number among the plurality of tracks to be connected as the track number of the connection track, or tracks among the plurality of tracks to be connected N is the track number of the track with the largest number, and m is the number of tracks to be connected.
n- (m-1)
The management number is configured to be updated so that the track number represented by the above is set as the track number of the connected track.
Alternatively, there is provided a track number designating unit capable of designating a track number to be attached to the connected track, and the management information update unit manages the track number designated by the track number designating unit as the track number of the connected track. The configuration is such that information is updated.
Alternatively, a track number designating unit capable of designating an arbitrary track number among the track numbers of tracks in a state before editing where a coupled track is formed is provided, and the management information updating unit is configured such that the playback order of the coupled track is track number. The management information is updated so that the track number after editing is set immediately before or immediately after the track specified by the specifying means.
[0011]
  Editing for editing audio data recorded on a recording medium comprising a recording area in which audio data is recorded and a management area in which management information for managing the audio data recorded in the recording area in units of tracks is recorded As a device, designation operation means capable of designating a plurality of discontinuous track numbers from a plurality of track numbers corresponding to a plurality of track units existing in a recording area, and a plurality of discontinuities from a plurality of track numbers by the designation operation means. If a specific track number is specified, a plurality of discontinuous track numbers specified by the specifying operation means can be edited by editing the management information in the management area.Combine tracks corresponding toThus, the control means for editing the management information like the control means for editing the management information and the recording means for re-recording the management information edited by the control means in the management area are provided.
[0012]

[0014]
<1. Configuration of playback device>
FIG. 1 shows a block diagram of the main part of the playback apparatus of the present embodiment.
A magneto-optical disk 1 on which audio data is recorded is driven to rotate by a spindle motor 2. The magneto-optical disk 1 is irradiated with laser light from the optical head 3 during recording / reproduction.
[0015]
The optical head 3 performs high-level laser output for heating the recording track to the Curie temperature during recording, and relatively low-level laser output for detecting data from reflected light by the magnetic Kerr effect during reproduction. .
For this reason, the optical head 3 is equipped with a laser diode as laser output means, an optical system including a polarizing beam splitter, an objective lens, and the like, and a detector for detecting reflected light. The objective lens 3a is held by a biaxial mechanism 4 so as to be displaceable in the radial direction of the disc and in the direction in which the objective lens 3a is in contact with or separated from the disc.
[0016]
A magnetic head 6a is disposed at a position facing the optical head 3 with the magneto-optical disk 1 interposed therebetween. The magnetic head 6a performs an operation of applying a magnetic field modulated by the supplied data to the magneto-optical disk 1.
The entire optical head 3 and the magnetic head 6 a can be moved in the radial direction of the disk by the thread mechanism 5.
[0017]
Information detected from the magneto-optical disk 1 by the optical head 3 by the reproducing operation is supplied to the RF amplifier 7. The RF amplifier 7 performs processing of the supplied information to reproduce RF signal, tracking error signal TE, focus error signal FE, and groove information (absolute position information recorded as a pregroove (wobbling groove) on the magneto-optical disk 1). Extract GFM and the like.
The extracted reproduction RF signal is supplied to the encoder / decoder unit 8. The tracking error signal TE and the focus error signal FE are supplied to the servo circuit 9, and the groove information GFM is supplied to the address decoder 10.
[0018]
The servo circuit 9 receives various servo drive signals based on the supplied tracking error signal TE, focus error signal FE, track jump command, access command, spindle motor 2 rotational speed detection information, etc. from a system controller 11 constituted by a microcomputer. The biaxial mechanism 4 and the sled mechanism 5 are controlled to perform focus and tracking control, and the spindle motor 2 is controlled to a constant linear velocity (CLV).
[0019]
The address decoder 10 extracts address information by decoding the supplied groove information GFM. This address information is supplied to the system controller 11 and used for various control operations.
The playback RF signal is subjected to decoding processing such as EFM demodulation and CIRC in the encoder / decoder unit 8. At this time, the address, subcode, etc. included in the playback RF signal are also extracted as data and sent to the system controller 11. Supplied.
[0020]
The audio data (sector data) decoded by the encoder / decoder 8 such as EFM demodulation and CIRC is temporarily written into the buffer memory 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 reproduction data in the system from the optical head 3 to the buffer memory 13 are 1.41 Mbit / sec, and are usually performed intermittently.
[0021]
The data written in the buffer memory 13 is read at a timing when the reproduction data transfer is 0.3 Mbit / sec and is supplied to the encoder / decoder unit 14. Then, a reproduction signal process such as a decoding process for the audio compression process is performed, and an analog signal is made by the D / A converter 15, supplied from the output terminal 16 to a predetermined amplifier circuit unit, and reproduced and output. For example, it is output as an L, R analog audio signal.
[0022]
When a recording operation is performed on the magneto-optical disk 1, the recording signal (analog audio signal) supplied to the input terminal 17 is converted into digital data by the A / D converter 18, and then the encoder / decoder. Is supplied to the unit 14 and is subjected to audio compression encoding processing.
The recording data compressed by the encoder / decoder unit 14 is temporarily written into the buffer memory 13 by the memory controller 12. When a predetermined amount or more of data is accumulated in the buffer memory 13, the data is read in a predetermined data unit and sent to the encoder / decoder unit 8. The encoder / decoder 8 performs encoding processing such as CIRC encoding and EFM modulation, and then supplies the magnetic head driving circuit 6 with the encoding processing.
[0023]
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, an N or S magnetic field is applied to the magneto-optical disk 1 by the magnetic head 6a. At this time, the system controller 11 supplies a control signal to the optical head so as to output a recording level laser beam.
Through the buffer memory 13, the recording operation for continuously input audio data is performed intermittently.
[0024]
The operation unit 19 is provided with various keys used for user operations. For example, a recording key, a reproduction key, a stop key, an AMS key, a fast forward key, a fast reverse key, and the like are provided, and operation information thereof is supplied to the system controller 11. In the recording apparatus of this embodiment, “divide”, “move”, “combine”, and the like can be selected as the editing mode, but an operation for selecting the recording / editing mode is also possible.
The display unit 20 is configured by a liquid crystal display, for example, and performs an operation of displaying an operation state, a track number, time information, and the like based on control of the system controller 11.
[0025]
When recording / reproducing operations are performed on the magneto-optical disk 1, management information recorded on the magneto-optical disk 1, that is, P-TOC (pre-mastered TOC), U-TOC (user TOC) is read out. There is a need. The system controller 11 determines the address of the area to be recorded on the magneto-optical disk 1 and the address of the area to be reproduced according to the management information. This management information is held in the buffer memory 13. For this reason, the buffer memory 13 is divided into the recording data / reproduction data buffer area and the area for holding the management information.
The system controller 11 reads out the management information by executing the reproducing operation on the innermost circumference side of the disk on which the management information is recorded when the magneto-optical disk 1 is loaded, and stores it in the buffer memory 13. The information can be referred to in the recording / reproducing operation for the magneto-optical disk 1 thereafter.
[0026]
The U-TOC is edited and rewritten in accordance with data recording or erasing. The system controller 11 performs this editing process on the U-TOC information stored in the buffer memory 13 each time recording / erasing is performed. The U-TOC area of the magneto-optical disk 1 is also rewritten at a predetermined timing according to the rewriting operation.
[0027]
<2. U-TOC Sector>
As described above, when the recording / reproducing operation is performed on the magneto-optical disk 1, the system controller 11 uses P-TOC, U-TOC (user TOC) as management information recorded on the magneto-optical disk 1. Is read and referred to.
Here, the U-TOC sector will be described as management information for managing the recording / reproducing operation of a track (musical piece or the like) in the magneto-optical disk 1.
[0028]
Note that U-TOC and P-TOC are provided as TOC information. This P-TOC is formed in the innermost pit area of the magneto-optical disk 1 and is read-only information. Then, the location of the recordable area (recordable user area), lead-out area, U-TOC area, etc. of the disc is managed by the P-TOC. In the mini-disc system, a playback-only disc in which all data is recorded in pit form can be used. However, in the case of a playback-only disc, the management of music recorded in ROM by P-TOC is also possible. The U-TOC is not formed.
A detailed description of the P-TOC is omitted, and here, the U-TOC provided in the recordable magneto-optical disk 1 will be described.
[0029]
FIG. 2 shows the format of the U-TOC sector 0.
Sector 0, sector 1, sector 2, and sector 4 are defined as U-TOC sectors. Sector 1 and sector 4 are character information, and sector 2 is an area for recording recording date and time. Here, only the U-TOC sector 0 that is absolutely necessary for the recording / reproducing operation of the magneto-optical disk 1 will be described.
The U-TOC sector 0 is a data area in which management information is recorded mainly on music recorded by the user and free areas where new music can be recorded.
For example, when recording a certain piece of music on the magneto-optical disk 1, the system controller 11 searches for a free area on the disk from the U-TOC sector 0 and records audio data therein. Become. Further, at the time of reproduction, the area where the music to be reproduced is recorded is determined from the U-TOC sector 0, and the area is accessed to perform the reproduction operation.
[0030]
In the data area (4 bytes × 588 2352 bytes) of the U-TOC sector 0, a synchronization pattern in which 1 byte data of all 0s or all 1s are formed side by side is recorded at the head position.
Subsequently, 4 bytes are added to the address which becomes the cluster address (Cluster H) (Cluster L) and the sector address (Sector) and the mode information (MODE), and the header is thus obtained.
[0031]
As described above, a sector is a data unit of 2352 bytes, and 36 sectors constitute one cluster. The synchronization pattern and address are recorded not only in the U-TOC sector 0 but also in the P-TOC sector and the data sector in which audio data is actually recorded, in the sector unit.
The cluster address is described by 2 bytes of an upper address (Cluster H) and a lower address (Cluster L), and the sector address (Sector) is described by 1 byte.
Next, at the specified byte position, manufacturer code, model code, track number of the first track (First TNO), track number of the last track (Last TNO), sector usage status (Used sectors), disk serial number, disk ID, etc. Data is recorded.
[0032]
Further, various table pointers (P) are used as the correspondence table instruction data portion in order to identify the track (music piece) area and free area recorded by the user by associating them with the management table portion described later. -DFA, P-EMPTY, P-FRA, P-TNO1 to P-TNO255) are recorded.
[0033]
Then, 255 parts tables (01h) to (FFh) are provided as management table sections corresponding to the table pointers (P-DFA to P-TNO255). Each part table has a certain part. The start address as the starting point, the end address as the end, and the mode information (track mode) of the part are recorded. In addition, since the parts shown in each part table may be connected to other parts in succession, link information indicating the part table in which the start address and end address of the connected part are recorded can be recorded. Has been.
In the present specification, the numerical value with “h” is a so-called hexadecimal notation. A part refers to a track portion in which temporally continuous data is physically continuously recorded in one track.
[0034]
In this type of recording / reproducing apparatus, even if the data of one music is physically discontinuous, that is, recorded over a plurality of parts, it is possible to reproduce while accessing between the parts, so there is no problem in the reproducing operation. The music recorded by the user may be recorded in multiple parts for the purpose of efficient use of the recordable area.
[0035]
For this reason, link information is provided, and the part tables can be connected by designating the part tables to be connected by, for example, the numbers (01h) to (FFh) given to the respective part tables.
In other words, in the management table section in the U-TOC sector 0, one part table represents one part. For example, for music composed of three parts connected, three parts connected by link information. The part position is managed by the table.
Actually, the link information is indicated by a numerical value that is a byte position in the U-TOC sector 0 by a predetermined calculation process. That is, the part table is designated as 304+ (link information) × 8 (byte).
[0036]
Each part table from (01h) to (FFh) in the management table part of U-TOC sector 0 is the table pointer (P-DFA, P-EMPTY, P-FRA, P-TNO1-P in the corresponding table instruction data part) -TNO255) shows the contents of the part as follows:
[0037]
The table pointer P-DFA indicates a defect area on the magneto-optical disk 1 and is the head of one part table or a plurality of part tables indicating a track portion (= part) that becomes a defect area due to a scratch or the like. The parts table is specified. In other words, if there is a defective part, one of (01h) to (FFh) is recorded in the table pointer P-DFA, and the defective part is indicated by the start and end addresses in the corresponding parts table. . When there are other defective parts, other part tables are designated as link information in the parts table, and the defective parts are also indicated in the parts table. If there is no other defective part, the link information is, for example, “(00h)”, and there is no link thereafter.
[0038]
The table pointer P-EMPTY indicates the first part table of one or more unused part tables in the management table section. If there is an unused part table, the table pointer P-EMPTY is (01h ) ~ (FFh) is recorded. When there are multiple unused part tables, the part tables are specified sequentially by link information from the part table specified by the table pointer P-EMPTY, and all unused part tables are linked on the management table section. Is done.
[0039]
The table pointer P-FRA indicates a free area (including an erasure area) in which data can be written on the magneto-optical disk 1, and one or a plurality of parts indicating a track portion (= part) as a free area. The first part table in the table is specified. In other words, if there is a free area, one of (01h) to (FFh) is recorded in the table pointer P-FRA, and the part table corresponding to it is indicated by the start and end addresses. Has been. Further, when there are a plurality of such parts, that is, there are a plurality of parts tables, the part information in which the link information is “(00h)” is sequentially designated by the link information.
[0040]
FIG. 3 schematically shows the management state of the parts that become free areas using the parts table. This means that when the parts (03h) (18h) (1Fh) (2Bh) (E3h) are set as free areas, this state is the part table (03h) (18h) (1Fh) following the corresponding table instruction data P-FRA. The state represented by the link (2Bh) (E3h) is shown. The management form of the above-described defective area and unused parts table is the same as this.
[0041]
By the way, if the magneto-optical disc has no recording of audio data such as music and has no defects, the parts table (01h) is specified by the table pointer P-FRA, which makes the entire recordable user area of the disc. Is shown as a free area. In this case, since the remaining (02h) to (FFh) part tables are not used, the part table (02h) is specified by the table pointer P-EMPTY described above, and the part table (02h) The parts table (03h) is specified as the link information, and so on. In this case, the link information of the parts table (FFh) is “(00h)” indicating 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.
[0042]
Table pointers P-TNO1 to P-TNO255 indicate tracks such as music recorded by the user on the magneto-optical disk 1. For example, the table pointer P-TNO1 is one or more in which data of the first track is recorded. The part table that shows the first part among the parts is specified.
For example, when the music set as the first track is recorded on the disc without being divided, that is, recorded as one part, the recording area of the first track is the part table indicated by the table pointer P-TNO1. Recorded as start and end addresses.
[0043]
Further, for example, when the music set as the second track is discretely recorded on a plurality of parts on the disc, each part is designated according to the temporal order to indicate the recording position of the second track. In other words, from the part table specified in the table pointer P-TNO2, other part tables are further specified in accordance with the time order in accordance with the link information, and the part table in which the link information becomes “(00h)” is linked. .
In this way, for example, all the parts in which the data constituting the second music is recorded are sequentially designated and recorded, so that the data of the U-TOC sector 0 is used to reproduce the second music or the second music. When overwriting recording is performed on this area, it is possible to access the optical head 3 and the magnetic head 6 to extract continuous music information from discrete parts, or to record using the recording area efficiently.
[0044]
As described above, with respect to the rewritable magneto-optical disk 1, area management on the disk is performed by the P-TOC, and music and free areas recorded in the recordable user area are performed by the U-TOC.
[0045]
<3. Example of recording status on disc>
Here, the area structure of the magneto-optical disk 1 will be described, and examples of recording states managed by the P-TOC and U-TOC will be described.
FIG. 4 schematically shows the area structure of the magneto-optical disk 1 in the radial direction. In the case of a magneto-optical disk, it is roughly divided into an area where data is recorded by embossed pits as shown in FIG. 4 as a pit area, and a groove area where grooves (grooves) are provided as so-called magneto-optical areas. It is done.
[0046]
Here, P-TOC is repeatedly recorded as the pit area, and in this P-TOC, the U-TOC position is the U-TOC start address UST._A And the lead-out start address LO_A Recordable user area start address RST_A , Power calibration area start address PC_A Each address position shown in FIG. 4 is shown.
[0047]
A groove area is formed following the innermost pit area of the magneto-optical disk 1, and the lead-out start address LO in the P-TOC within this groove area._A The area up to the address shown as is a recordable area that can be recorded, and the subsequent area is a lead-out area.
Further, in this recordable area, a recordable user area where data such as music is actually recorded is a recordable user area start address RST._A Lead out start address LO_A Until the position just before.
[0048]
Then, in the groove area, the recordable user area start address RST_A The preceding area is a management area for recording / reproducing operation, the above-mentioned U-TOC is recorded, and the power calibration area start address PC_A One cluster from the position shown as is provided as a laser power calibration area.
The U-TOC has a U-TOC start address UST in the management area for the recording / reproducing operation._A 3 clusters (1 cluster = 36 sectors) are recorded continuously from the position shown in FIG.
[0049]
The actual audio data is recorded in the recordable user area as exemplified in FIG. In this case, 4 tracks (music) M₁ ~ M_Four Shows the case where is recorded.
First address A₀ ~ A₁ Track M, the first song as part of₁ Is recorded and track M is the second song₂ Is address A₂ ~ A_Three The early part M recorded in the parts of_2-1 And address A₆ ~ A₇ End part M recorded in the parts of_2-2 It is recorded in a split. Also, the third track, track M_Three Is address A_Four ~ A_Five Track M, which is recorded in the parts and becomes the fourth song_Four Is address A₈ ~ A₉ It is recorded in the parts.
In this state, the free area where no music is recorded is address A._Ten~ A₁₁Parts.
[0050]
Next, FIG. 5 shows an example of U-TOC data in the state of FIG.
In this figure, the table pointer in the U-TOC and the 1-byte data as link information are set to “00h”, and the 3-byte data as the start address and end address are set to “000000h”. The part is indicated by “−”.
Furthermore, it is assumed that the recordable user area on the magneto-optical disk 1 is not defective, and therefore the table pointer P-DF_A Is “00h”.
[0051]
In the recording state of FIG. 4, the table pointer P-FR_A To manage the free area, for example in this case the table pointer P-FR_A If a parts table of (06h) is shown in FIG. 5, correspondingly, the parts table (06h) shows information on the parts to be free areas in FIG. That is, address A_TenIs the start address, address A₁₁Is shown as the end address. In this case, since there are no other free area parts, the link information of the parts table (06h) is set to “00h”.
[0052]
The first track M₁ Is the start address A in the part table (01h) indicated by the table pointer P-TNO1.₀ And end address A₁ Is shown. Track M₁ Is recorded as one part, the link information of the parts table (01h) is “00h”.
[0053]
Second track M₂ Is the start address A in the part table (02h) indicated by the table pointer P-TNO2.₂ And end address A_Three It is shown. However, track M₂ Is two parts (M_2-1 And M_2-2 ) Is recorded separately, address A₂ And address A_Three Is track M₂ Early part of (M_2-1 ) Only. Therefore, for example, the parts table (04h) is shown as the link information of the parts table (02h), and the parts table (04h) has an end part (M_2-2 ) Start address A to indicate parts₆ And end address A₇ Is recorded. Since no link is required thereafter, the link information of the parts table (04h) is set to “00h”.
[0054]
Third track M_Three , 4th track M_Four The position of each part is managed by a part table obtained from the table pointers P-TNO3 and P-TNO4, respectively. Since only four songs are recorded, the table pointers P-TNO5 to P-TNO255 are not used and are set to “00h”.
In addition, the table pointer P-EMPTY indicating the parts table not in use 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.
[0055]
<4. Combine editing process as this embodiment>
(A. Combine editing process as the first embodiment)
Next, the combine editing process according to the present embodiment will be described. First, the combine editing process according to the first embodiment will be described with reference to FIGS.
FIG. 6A shows an example of a recording state in a recordable user area (see FIG. 4) of a certain magneto-optical disk. In this case, parts a to f are sequentially consecutive from the recordable user area. Is recorded as a free area immediately after the part f to the end position of the recordable user area. Address A shown in this figure₁₀₀ ~ A₁₁₃ Indicates the start address or end address of each part af and free area.
In addition, as shown in FIG. 6B, the parts a to f recorded on the disc are each handled as one track, and the parts a to f become tracks 1 to 6 respectively. Thus, the track number is set and managed.
[0056]

Here, as an example of the combine editing process of the present embodiment for the disc in the recording state and the U-TOC management state, as shown in FIGS. 6B to 6C, a part a ( A case will be described in which a combine editing process for forming one track is performed by connecting part c (track 3) to the back of track 1).
In the present specification, hereinafter, tracks formed by being connected by the combine editing process are referred to as “connected tracks”.
[0058]
For example, when the combine editing mode is set by a required key operation on the key operation unit 19, in the case of the present embodiment, a display as shown in FIG. 7A is displayed on a predetermined display area of the display unit 20. Is done. This display indicates that the current combine editing mode is indicated by the character display of “CONBINE”, and by displaying “Tr +”, the two tracks to be connected are positioned in front of the playback time axis. This is a display prompting the input of the track number of the track to be different. Under this display state, the user can designate and input a desired track number with a numeric key or the like. In this case, a numerical value “1” indicating the track 1 as the part a is input.
As described above, when the track number of the track positioned in the previous playback time is input, the display is switched to a display such as “Tr1 + Tr” as shown in FIG. Of the two tracks, the input of the track number of the track that will be positioned later in the playback time is prompted. In this case, a numerical value “3” indicating the track 3 as the part c is input.
In this way, when two previous and subsequent tracks are input as tracks to be connected, the display is switched to that shown in FIG. In this figure, for example, [Tr1 + Tr3 → Tr1] is displayed. This indicates that the tracks are connected in the order of track 1 → track 3, and the track number after the connection editing is managed as track 1. It is in a state.
[0059]
In this embodiment, the track number setting rule for the connected tracks is as follows. Here, it is assumed that two tracks are connected, and the smaller track number of these two tracks is automatically connected. The track number has been set. In this case, since the track 1 and the track 3 are connected to form one connection track, the connection track in this case is managed as the track 1 as shown in FIG.
[0060]
Then, when the user sees the display of FIG. 7C and confirms that there is no mistake in the input operation, the user performs an enter operation by a required key operation.
As a result, the relationship between the parts and the track managed as shown in FIG. 7B before the combine editing process is managed as shown in FIG. 7C after that. That is, the connected track formed by connecting parts (a → c) becomes track 1, and the remaining parts b, d, e, and f that are not connected follow the original track order. These are reset as tracks after track 2, respectively.
That is, the part b is set as the track 2, the part d is set as the track 3, the part e is set as the track 4, and the part f is set as the track 5.
[0061]
The data content of the U-TOC for managing the recording data so that the relationship between the parts and the track after the combine editing process shown in FIG. 6C is obtained is as shown in FIG. Note that description of the same data content portion as in FIG. 8 in which the data content of the U-TOC before the combine editing is shown is omitted.
In this case, the table pointer P-TNO1 has “01h” (part a; the previous part of the connected track (a → c)), the table pointer P-TNO2 has “02h” (part b), and the table pointer P-TNO3. “04h” (part d), the table pointer P-TNO4 stores “05h” (part e), and the table pointer P-TNO5 stores a value indicating “06h” (part f). Since the track 6 disappears after the combine editing, the table pointer P-TNO6 becomes “00h”.
[0062]
In the parts table, the value of “03h” is stored in the link information area of the parts table (01h) and linked to the parts table (03h). This indicates that the part a is linked to the part b to form one connection track.
[0063]
After the combine editing process according to the operation procedure shown in FIG. 7, the U-TOC data is handled as being rewritten with the contents shown in FIGS.
Note that such rewriting (updating processing) of U-TOC data is performed in the U-TOC area on the buffer memory 13 every time editing processing is executed. Then, at a predetermined opportunity and timing, the U-TOC area on the magneto-optical disk 1 is updated based on the data content of the U-TOC area on the buffer memory 13.
[0064]
(B. Combine editing process as the second embodiment)
Next, with reference to FIGS. 10 to 12, the combine editing process as the second embodiment will be described.
In this case, the recording state of the magneto-optical disk and the management state of the recording data before editing are the same as those described in FIGS. 6A, 6B, and 8 in the first embodiment. The following description will be made on the assumption that this is the case.
[0065]
FIG. 10A shows the relationship between the same parts and tracks as in FIG. 6B. As an example of the combine editing process of the present embodiment, a case where the combine editing process is performed by connecting the part a (track 1) to the back of the part c (track 3) will be described.
[0066]
Also in this case, the combine mode is set by the user's key operation so that the display for the combine mode is performed on the display unit 20, and then, in the same manner as described with reference to FIGS. As the tracks to be connected, the track numbers of the tracks that are before and after the playback time are designated and input.
When the input of the two track numbers to be connected is completed, in the case of the present embodiment, for example, a display of [Tr3 + Tr1 → Tr2] is performed as shown in FIG. This is a state in which the tracks are connected in the order of track 1 → track 3, and the track number after the connection is shown to the user as being managed as track 2.
[0067]
In the second embodiment, for example, as a track number to be set as a concatenated track, if n is a track number of a large track number of two tracks to be concatenated, n-1 is automatically set as the track number. Is set to
That is, in the first embodiment, the track number of the connected track is set such that the smaller of the two connected tracks is the main track number, but in this embodiment, the track number is set as the track number. The track number of the connected track is set so that the larger one is the main. In this case, the track with the smaller track number is connected to the track with the larger track number.Be doneAs a result, since the track number after the combine editing is inevitably incremented by one, n-1 is set as the track number of the connected track.
In this example, the track having the largest track number among the two tracks to be connected is track 3, and n = 3.
n-1 = 3-1 = 2
Thus, the track formed by the connection is managed as the track 2.
[0068]
The track number n-1 to be set as a connected track is derived only when two tracks are connected. For example, the track number n-1 is provided with a combine editing function for connecting a plurality of tracks. In the case of following the rule that the largest track number n is the main among the track numbers of a plurality of tracks, m is the number of tracks to be connected,
n- (m-1)
Thus, the track number to be set for the connected track can be derived. “M−1” represents the number of tracks advanced (decreased) by the connection process.
[0069]
In this case as well, when the user confirms that there is no mistake in the input operation by looking at the display in FIG. 11, and performs the enter operation by the required key operation, the subsequent operation is performed in the form shown in FIG. The relationship between parts and tracks will be managed. In this case, the part b becomes the track 1, the connected track by the parts (c → a) formed by the connected editing becomes the track 2, and the parts d, e, and f become the track 3, the track 4, and the track 5, respectively. .
[0070]
FIG. 12 shows the data contents of the U-TOC for managing the parts and tracks so as to have the relationship shown in FIG. Note that a description of the same data content as in FIG. 8 is omitted.
In the case of FIG. 12, “02h” (part b) for the table pointer P-TNO1 and “03h” (parts) for the table pointer P-TNO2 corresponding to the relationship between the parts and tracks shown in FIG. c: “04h” (part d) for table pointer P-TNO3, “05h” (part e) for table pointer P-TNO4, table pointer P-TNO5 A value indicating “06h” (part f) is stored.
[0071]
In the parts table, the value of “01h” is stored in the link information area of the parts table (03h) corresponding to the part c, so that the part c (part table (03h)) Are linked to the parts table (01h) corresponding to the, and are managed as one track.
[0072]
(C. Combine editing process as the third embodiment)
Next, with reference to FIG. 13 to FIG. 15, the combine editing process as the third embodiment will be described. The combine editing process of the present embodiment is configured such that the user can arbitrarily specify and set the track number after editing set for the connected track.
In describing the example of the combine editing process of the present embodiment, the recording state of the magneto-optical disk and the management state of the recording data before editing are the same as in the previous embodiments, as shown in FIG. It is assumed that the content is the same as b) and FIG.
[0073]
FIG. 13A shows the relationship between the same parts and tracks as in FIG. 6B. Then, as an example of the combine editing process of the present embodiment, as shown in FIG. 13 (a) → (b) as the transition of the management state, the track 3 before the part a which is the track 1 before editing A case where a part c (track 1) is connected, and the combined part (a → c) is subjected to combine editing processing so that it is managed as a track 5 after editing will be described together with an example of its operation.
[0074]
Also in this embodiment, as in the operation in the previous embodiments, in the combine mode, designation input of each track number before and after to be connected is performed, but when the input of these track numbers is completed, this operation is performed. In this form, as shown in FIG. 14A, for example, the content of “Tr1 + Tr3 → Tr” is displayed on the display unit 20. This indicates that the track numbers before and after the linking process are track 1 (part a) and track 3 (part c), respectively, and the track after editing of one track obtained by linking these tracks. It is displayed that the user is prompted to enter the number.
[0075]
In this case, it is assumed that the user wants to attach the track number of the last track among all the tracks for the tracks of the parts (a → c) formed by being connected. In this case, as shown in FIGS. 13A to 13B, the total number of tracks is changed from 6 tracks to 5 tracks after the combine editing, so that the user can specify track 5 as the designated track number of the connected track. It is sufficient to specify and input.
Then, when the designation of the track 5 is performed by the user's key operation, the display unit 20 displays “Tr1 + Tr3 → Tr5” as shown in FIG. 14B, and the track number of the connected track after the editing process. Is to be managed as a track 5. The user performs an enter operation after confirming that there is no mistake in the input operation by looking at the display content shown in FIG. As a result, the recording data is managed so that the relationship between the part and the track shown in FIG.
In this case, the parts b, d, e, and f are the tracks 1, 2, 3, and 4, respectively, and the track by the part (a → c) that is the connected track is managed as the track 5 that is the final track. The
[0076]
FIG. 15 shows the data content of the U-TOC for managing the parts and the track as shown in FIG. 13B. In this case, the description of the same data content as in FIG. 8 is omitted.
In the case of FIG. 15, corresponding to the relationship between the parts and tracks shown in FIG. 13B, the table pointer P-TNO1 has “02h” (parts b) and the table pointer P-TNO2 has “04h” (parts d ), “05h” (part e) for the table pointer P-TNO3, “06h” (part f) for the table pointer P-TNO4, “01h” for the table pointer P-TNO5 (part a: connected track (a → Each value indicating the previous part) of c) is stored.
In the parts table, the value of “03h” is stored in the link information area of the parts table (01h) corresponding to the part a so that the part c is managed as one track by linking the part a to the part a. Is stored.
[0077]
(D. Combine editing process as the fourth embodiment)
Next, with reference to FIG. 16 to FIG. 18, the combine editing process as the fourth embodiment will be described. Also in the combine editing process of the present embodiment, the user can arbitrarily designate and set the track number after editing set for the connected track. However, the concept of the designated track number is the above-described third concept. Different from the embodiment.
In describing the example of the combine editing process of the present embodiment, the recording state of the magneto-optical disk and the management state of the recording data before editing are the same as in the previous embodiments, as shown in FIG. It is assumed that the content is the same as b) and FIG.
[0078]
FIG. 16A shows the relationship between the same parts and tracks as in FIG. 6B.
As the operation at the time of the combine editing process of this embodiment, after inputting the designation of each track number before and after being connected in the same manner as in the previous embodiments, the designation input of the track number of the connected track is performed. However, the track number designation is based on the following concept.
[0079]
In the present embodiment, as the operation for specifying the track number of the connected track, the track number of the track immediately after the connected track after editing is specified by the track number before editing. In other words, the track immediately before the designated track number is set to be a connected track.
Therefore, the user designates the track number based on the track number before editing. For this reason, as the operation for specifying the track number of the connected track, the track number of the track immediately after the connected track after editing is specified by the track number before editing.
[0080]
Here, a specific operation example is as follows.
FIG. 16A shows the relationship between the same parts and tracks as in FIG. 6B. In this case, the track 3 (part c) is connected to the track 1 (part a). Assume that a connected track is formed, and this connected track is set as the track immediately before the part e as the order of the reproduction music.
[0081]
The display of the display unit 20 for designating and inputting the track number of the connected track according to the present embodiment is, for example, “Tr1 + Tr3 → (BEFORE) Tr” as shown in FIG.
This is the content that is displayed after inputting the track numbers before and after being connected in the same way as in the previous embodiments, and the track to which the connected track consisting of parts a → c is positioned immediately before. This is a display for inputting this by the track number before editing.
When the user performs an operation for inputting “track 5 (” as a designated track under this display state, “Tr1 + Tr3 → (BEFORE) Tr5” is displayed as shown in FIG. Thus, the connected track composed of the parts (a → c) is managed as the track immediately before the track 5 as the track number before editing.
Then, when the user performs an enter operation thereafter, the recording data is managed so that the relationship between the part and the track shown in FIG.
[0082]
In this case, parts b and d are tracks 1 and 2, respectively. The connected track of parts (a → c) is track 3, and part e is the track immediately before the corresponding track 4. The remaining part f becomes the track 5.
[0083]
In such a track number specification input method, the user does not need to specify the track number to be set for the connected track after predicting the track number of the track that will be changed after the combine editing. As long as the correct track order (song order) is known, designation input can be performed based on the track number before editing, so that the user does not inconvenience the operation.
[0084]
The data content of the U-TOC for managing the parts and tracks as shown in FIG. 16B is as shown in FIG. Note that a description of the same data content as in FIG. 8 is omitted.
In the case of FIG. 18, “02h” (part b) for the table pointer P-TNO1 and “04h” (part d) for the table pointer P-TNO2 corresponding to the relationship between the parts and tracks shown in FIG. ), “01h” (part a: the previous part of the connected track (a → c)) for the table pointer P-TNO3, “05h” (part e) for the table pointer P-TNO4, and “ "06h" (part f) is stored.
In the parts table, the value of “03h” is stored in the link information area of the parts table (01h) corresponding to the part a, and managed as one connected track by linking the part c to the part a. Indicates that
[0085]
(E. Combine editing process as the fifth embodiment)
Next, with reference to FIGS. 19 to 21, the combine editing process as the fifth embodiment will be described. In the combine editing process of the present embodiment, the connected track is set to be a track immediately after the designated track. Also, the designation of the track number is input by the track number before editing as in the fourth embodiment.
[0086]
FIG. 19A shows the relationship between the same parts and tracks as in FIG. 6B. Also in this case, the recording state of the magneto-optical disk and the management state of the recording data before editing are the same as those shown in FIGS.
Also in this case, the user inputs the track 1 (part a) and the track 3 (part c) as the track numbers before and after being connected in the combine mode. Then, for example, as shown in FIG. 20A, “Tr1 + Tr3 → (AFTER) Tr” is displayed. This display is used to input a track number before editing, which track is positioned immediately after a connected track formed by connecting track 3 (part c) to track 1 (part a). Display.
Here, if the user inputs the track 5 under the display state of the display unit 20 shown in FIG. 20A, for example, “Tr1 + Tr3 → (AFTER) Tr5” as shown in FIG. 20B. The display changes to indicate that the connected track (parts a → c) is designated to be the track immediately after track 5 (track number before editing).
[0087]
When the user performs an enter operation in the state shown in FIG. 20B, the recording data is managed so that the relationship between the parts and tracks shown in FIG. The
In this case, parts b and d are tracks 1 and 2, respectively. Then, the part e becomes the track 3, and subsequently, the connected track by the parts (a → c) is the track 4. The remaining part f is managed as a track 5.
[0088]
FIG. 21 shows the data content of the U-TOC for managing the recording data so that the relationship between the part and the track shown in FIG. Note that a description of the same data content as in FIG. 8 is omitted.
In FIG. 21, “02h” (part b) is stored in the table pointer P-TNO1 and “04h” (part d) is stored in the table pointer P-TNO2 in correspondence with the relationship between the parts and tracks shown in FIG. The table pointer P-TNO3 is “05h” (part e), the table pointer P-TNO4 is “01h” (part a: the previous part of the connected track (a → c)), and the table pointer P-TNO5 is “06h”. ] (Part f) is stored.
In the parts table, the value of “03h” is stored in the link information area of the parts table (01h) corresponding to the part a, and managed as one connected track by linking the part c to the part a. Will be shown.
[0089]

[0090]
In this routine, first, in step S101, in the normal mode or other editing mode, a key operation for shifting to the combine mode is waited. Here, there is a key operation for shifting to the combine mode. If it is discriminated, the process proceeds to step S102 to shift to the combine mode, and in the next step S103, the input operation of the track number of the preceding track of the two tracks to be connected is awaited. In this step, for example, display control for displaying on the display unit 20 as shown in FIG.
If the track number input operation in step S103 is performed, then in step S104, the track number input operation of the track behind the two tracks to be connected is waited for. In this step, display control for performing display as shown in FIG. 7B is also executed.
[0091]
When the track number input operation in step S104 is performed, the process proceeds to step S105 to wait for an enter process for executing the combine process. In this step, for example, display control in the display unit 20 as shown in FIG. 7C or FIG. 11 is executed.
When it is determined in step S105 that the enter operation has been performed, the system controller 11 executes at least a process of rewriting the U-TOC area on the buffer memory 13 in order to execute the combine editing process. Specifically, the link information of the required parts table is updated so that the previous and subsequent tracks input in steps S103 and S104 are connected as one track, and the first embodiment or the second described above. The contents of the table pointer are updated in accordance with the track number setting rules for the connected tracks in the embodiment.
When the combine editing process in step S106 is completed, the combine mode is ended in the next step S107, and the process returns to the original routine.
[0092]
Although not shown as the processing steps in FIG. 22, for example, in the state of the combine mode, an operation for shifting to another mode was performed, or no input operation was performed for a predetermined time or more. In such a case, the combine mode is immediately terminated to shift to another required mode or the normal mode.
[0093]
(B. Processing operations corresponding to the third to fifth embodiments)
FIG. 23 is a flowchart showing a processing operation capable of realizing the combine editing process as the third to fifth embodiments among the combine editing processes as the embodiment described so far.
[0094]
Steps S201 to S204 shown in the routine shown in FIG. 23 are the same as steps S101 to S104 in FIG.
Step S205 is a process of waiting for the designation of the track number to be set for the connected track. In step S205, processing for executing display on the display unit 20 as shown in FIG. 14A, FIG. 17A, or FIG. 20A is executed.
In this routine, after the track number designation input is made in step S205, the enter operation is waited for in step S206. In step S206, process control for realizing the display as shown in FIG. 14B, FIG. 17B, or FIG. 20B is executed.
If it is determined in step S206 that an enter operation has been performed, a combine edit process (U-TOC rewrite process) is executed in step S207. In this case, the table pointers corresponding to the parts of the connected tracks and the track number setting rules of the connected tracks in the third embodiment, the fourth embodiment, or the fifth embodiment described above and The parts table will be updated.
When the combine editing process in step S207 ends, the combine mode is ended in step S208, and the process returns to the original routine.
[0095]
In each of the above-described embodiments described so far, the case has been described in which the combination editing process is performed from the state where each part is recorded and managed on the disk as one track. Even when the tracks to be connected are already discretely recorded on the disc as a plurality of parts, the combine editing process is performed without any problem.
In each of the above embodiments, the combine editing process for connecting two tracks has been described as an example. However, the combine editing process of the present invention is also applicable to combine editing for connecting three or more tracks. Is possible.
In addition, the input operation method for combine editing described in the above embodiments is merely an example, and other operation procedures are conceivable.

However, as a dedicated device for editing management information, separately from the recording / reproducing device. Of course, it can be realized.
Further, as an embodiment, an example in which the present invention is applied to a mini-disc system has been described. However, the present invention can be applied to any system in which recording data is managed by management information, and the recording medium is a disc-shaped recording. Other than the medium, for example, the present invention can be applied to a recording apparatus corresponding to a recording medium on a tape or a solid memory.
[0096]
【The invention's effect】
As described above, the management information editing apparatus according to the present invention enables, as a combine editing function, a plurality of tracks that do not have consecutive track numbers corresponding to the playback order to be connected, and the track numbers corresponding to the connected tracks are predetermined.
