Description

  The present invention relates to a recording / playback control system, a recording / playback control method, and a recording which enable a user to easily select a program when recording, playing back or recording / playback information signals such as audio information and video information. The present invention relates to a playback control apparatus and method.

  Various information signal reproducing devices or recording / reproducing devices exist. In the case of digital audio signals, CD (compact disc) players, MD (mini disc) players, MD recorders (recording and playback), DAT (digital audio tape recorders) and the like are known. It is also known to perform digital or analog audio signal dubbing between these devices. In dubbing, it is necessary to specify the music of the audio signal to be recorded. For example, when a song reproduced from a CD is dubbed to the MD, a part or all of the song recorded on the CD is designated and recorded on the MD. Further, in the case of a CD changer, music included in a plurality of CDs is designated and reproduced and recorded on the MD. Furthermore, there may be a plurality of recordable recording media such as an MD changer.

  As a method of dubbing a desired song in a desired song order when there are a plurality of songs to be recorded in this way, there is a method in which the player plays the songs one by one and records the reproduced songs. . As another dubbing method, prior to the actual recording, the selection information of the music to be recorded is stored in some storage means, and the player performs the playback operation accordingly, while the recorder operates in synchronization with the playback operation. There is a method for controlling the recorder and the player to perform the recording operation. Further, in the case of a changer in which the player or recorder selects one of a plurality of media, it is necessary to specify a reproduction medium or a recording medium.

  When dubbing is performed, in any of the methods, the music piece is selected by designating the piece information piece by number or the like while watching the jacket. In the case of a changer, it is necessary to specify not only the piece of music but also the medium using numbers. In some cases, it is necessary to specify the order of songs. Such a selection operation is not limited to dubbing, but is similarly performed during program reproduction in which a piece of music to be reproduced is set in advance. Furthermore, the music order can be changed as in the case of MD, and when the music order is changed after recording, the target music number is designated by a number, and the changed music number is also a number. It is made to specify.

  The conventional operation of selecting a song or medium or changing the song order is performed by inputting information such as a song, medium, and song order one by one. Therefore, input work takes time and is not efficient. In addition, it is difficult to grasp the entire situation, and it is impossible to know the whole selectable music piece or the whole selected music piece. In addition, when using a medium that can change the song order, when changing the song order, the target song number is designated by numbers, and the changed song number is designated by numbers. It is not efficient.

Therefore, the operation efficiency is improved as compared with the work of designating one song at a time.

  According to the present invention, it is possible to efficiently perform a program selection operation required for dubbing. Further, since a dubbable program and a selected program can be displayed simultaneously as a window, the entire processing can be easily grasped, and more efficient work can be performed.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an example of an audio playback system including a personal computer 1 as a recording / playback control apparatus according to the present invention. The personal computer 1 is a standard computer including a main body 2 including a CPU, RAM, ROM, hard disk, interface, input / output port, etc., a display 3, a keyboard 4, and a mouse 5. For example, application software stored in a CD-ROM Is installed in the hard disk of the main body 2, thereby functioning as a recording / reproducing control device of the audio recording / reproducing system.

  As the digital audio signal reproducing device controlled by the personal computer 1, two CD changers 6a and 6b are used. As the digital audio signal recording device, an MD recorder 7 is used, and further, an amplifier 8 is used. The personal computer 1, these CD changers 6a and 6b, and the MD recorder 7 are connected in a chain shape by a control signal transmission path (shown by a solid line). The operation of each device is controlled by a control signal transmitted through the control signal transmission path. The control signal is sent from the personal computer 1. However, the operation of each device can be controlled by the operation unit of each device or a remote control system.

  A matching converter 10 is provided between the signal transmission path of the personal computer 1 and the signal transmission path of the audio system to absorb the difference in the form of the control signal. The personal computer 1 and the converter 10 are coupled by a signal transmission path such as RS-232C or SCSI, and the audio device side including the CD changer 6b from the converter 10 transmits a signal for controlling the audio device. Road is arranged.

  In FIG. 1, the transmission path of an audio signal (analog or digital) is indicated by a broken line. Playback audio signals of the CD changers 6 a and 6 b and the MD recorder 7 are input to the amplifier 8. The audio signal selected by the amplifier 8 is reproduced by the speaker 9.

  FIG. 1 shows only an example of a system to which the present invention can be applied. For example, for a system in which an AV controller is used, a plurality of AV devices (not only audio devices but also video devices such as digital VCRs) are connected to the AV controller in a star shape, and a personal computer is connected to the AV controller. Also, the present invention can be applied. If IEEE1394 is used as an interface between the personal computer 1 and an audio device such as the CD changer 6a, it is not necessary to separate the transmission path between the digital information signal and the control signal.

  The control signal transmission path is bi-directional, and on this transmission path, a program (song name) and a CD (medium) are provided along with operation control data and a clock for controlling the operation (recording operation, reproduction operation, etc.) of each device. ) And the corresponding identification information is transmitted. The identification information corresponding to the CD is, for example, a disc name given to the CD. A typical example of identification information corresponding to a program is character information representing a song title. For example, a CD text system that records character information such as a CD disc name, a song title, and a player name using a CD lead-in area has been put into practical use. The character information of the disc name and the song name is used as identification information. Also, there is a function (called a custom file) in which a user inputs characters (English, numbers, katakana, etc.) such as a disc name and song name corresponding to each CD, and holds the input character information in a nonvolatile memory. It has been put into practical use. In this case, the input character information is used as identification information.

  Character information such as a song name is useful for identifying each song when displayed on the display 3 of the personal computer 1. However, information other than character information can be used as long as the user can identify the CD and the song and can control the device to play the selected CD and the song. In the case of a CD, TOC data is recorded in a management lead-in area. This TOC data includes the start address (absolute time) of each song (indicated by the track number) of the CD. Therefore, the performance time of each song is known from the TOC information. The performance time for each song can be used as identification information. The total performance time of the CD is also known from the TOC information. The total performance time can be used as CD identification information. This is because there is usually a low probability that there are songs whose performance times are exactly the same, and there is a low probability that there are CDs whose total performance times are exactly the same.

  The above-described custom file stores the total performance time and the inputted character information in the memory in association with each other, and when the CD is loaded, the user can make the CD based on the total performance time obtained from the TOC information. The assigned disk name is read from the memory and displayed. Furthermore, by increasing the amount of memory, the user can input not only the disc name but also the song name of each song. In this case, each song can be associated with a song name according to the performance time for each song described above.

  In one embodiment of the present invention, a first window 11, a second window 12, and a third window 13 are displayed on the screen of the display 3 of the personal computer 1, as will be described later. Identification information such as a disc name and a song name as described above is displayed on these windows. The user can select a CD and a song to be recorded by the MD recorder by dragging and dropping the mouse 5. The operation of the CD changers 6a and 6b, the MD recorder 7 and the amplifier 8 can be controlled by clicking icons and buttons in the screen. Furthermore, by clicking an icon or button in the screen, editing in units of songs (for example, combining two songs) can be performed.

  The graphical view and operation method when the user uses the display 3 such as the window function, the CD and song selection function using the mouse 5, and the operation control function using the icon and the mouse are the GUI (Graphical User Interface). ) Provided by software. Here, the mouse 5 is used, but as a device operated by the user, a trackball, a cursor key, a rotary knob, etc. can be used in addition to the mouse.

  FIG. 2 shows a more detailed configuration of each component in the system. In FIG. 2, for the sake of simplicity, one CD changer 6 is used, and an MD recorder 7 is connected to the personal computer 1. The CD changer 6 will be described. For example, among the five CDs, one selected CD 21 is mounted on the CD rotating unit and rotated by the spindle motor 23. A plurality of songs are recorded on the CD 21 as pit patterns, and the TOC is recorded in the lead-in area at the innermost peripheral position. The pickup 24 optically reads information on the CD 21. When the CD 21 is loaded, the pickup 24 reads the TOC prior to the music playback operation. When the CD 21 conforms to the CD text format, the CD text information is read as the TOC.

  A signal from the pickup 24 is supplied to the RF amplifier 25. The RF amplifier 25 has a function of an RF signal processing circuit, and performs processing such as binarization of the RF signal, generation of a tracking error signal, and a focus error signal. These error signals are supplied to the servo circuit 26. The servo circuit 26 performs focus control and tracking control processing, and servo for rotating the spindle motor 23 at CLV (constant linear velocity) is performed. A focus actuator and a tracking actuator in the pickup 24 are driven by a signal from the servo circuit 26. Further, although not shown, the servo circuit 26 also controls a device for feeding the pickup 24 in the disk radial direction. The servo circuit 26 and the control unit 27 are connected, and a desired music on the CD 21 can be accessed by a control signal from the control unit 27.

  The binarized reproduction signal from the RF amplifier 25 is supplied to the signal processing circuit 28. The signal processing circuit 28 includes a PLL, an EFM demodulation circuit, an error correction circuit, and the like. The digital audio signal from the signal processing circuit 28 is converted into an analog audio signal by the D / A converter 29 and taken out to the audio output terminal 30. Memory control or the like in the signal processing circuit 28 is performed by the control unit 27. Further, the subcode is supplied to the control unit 27 by the signal processing circuit 28.

  The control unit 27 includes a subcode processing unit. In the subcode processing unit, subcode error detection processing, subcode P and Q channels, R to W channel separation processing, decoding processing of each channel, and the like. Is made. The P channel of the subcode has information corresponding to the presence or absence of a program, and the Q channel has absolute time information on the CD, time information of each song, song number (also called track number), movement number ( Information such as an index) is also included. Therefore, it is possible to control the playback operation such as the beginning of the song by the information included in the Q channel, and by displaying the information of the Q channel, the number of the song on the optical disc that is being played is displayed. You can visually check the elapsed time of the performance and the absolute time from the beginning.

  Furthermore, a system (CD text) for recording additional character information on a CD using the R to W channels of the subcode of the lead-in area has been put into practical use. In the case of this CD text, it is possible to record character information of about 6500 characters, and additional character information of the CD is assumed to be 800 characters or less, so that it can cope with languages of 8 countries. . CD text data can be obtained by decoding the subcodes of the R to W channels with a CD text decoder. The TOC information and the CD text data are stored in the TOC memory and the CD text memory of the memory unit 31 connected to the control unit 27, respectively. In this case, all CD text data may be stored. However, in order to reduce the capacity of the memory unit 31, CD text data for disc and song identification (that is, disc name, song name, artist name). ) Only may be stored.

  The type of CD text can be determined by ID1 defined in the CD text format (mode 4). That is, this ID1 indicates the contents of the character string. For example, ID1 (80h) indicates the disc name / program name, (81h) indicates the performer / conductor / orchestra name (collectively referred to as artist name), (82h) indicates the composer, and (83h) indicates the composer.

  When the CD changer 6 has a custom file function, the memory unit 31 is provided with a custom file memory (nonvolatile memory). Then, the character information (disc name and song name) input by the user is stored in the custom file memory in one-to-one correspondence with the CD and each song in the CD. In this case, the disc name is stored in association with the total performance time of the CD based on the TOC information, and the song name is stored in correspondence with the performance time of each song.

  The TOC data recorded on the CD will be described. This uses the Q channel of the subcode. The subcode has a data structure with 98 bits as one frame. Of these 98 bits, 72 bits are data. When POINT in the TOC is 00 to 99, PMIN, PSEC, and PFRAME indicate the start address (absolute time) of each song. When POINT is A0, PMIN indicates the music number of the first song on the disc, and PSEC and PFRAME are 00. When POINT is A1, PMIN indicates the song number of the last song, and PSEC and PFRAME are 00. When POINT is A2, PMIN, PSEC, and PFRAME indicate addresses at which lead-out starts. Such TOC data is read when the CD is loaded and stored in the TOC memory of the memory unit 31.

  An interface 32 is connected to the control unit 27. A control signal input / output terminal 33 is led out from the interface 32. A control signal via the control signal transmission path is supplied from the terminal 33 to the control unit 32, and the control operation of the CD changer 6 is controlled by the control unit 32. Further, a signal indicating the state of the CD changer 6 and the identification signal can be output to the outside via the control unit 32. The identification signal is CD text data, custom file data, or the total performance time and performance time. Further, signals accompanying data transmission such as a clock and a reset signal are also input / output. As an example, communication is synchronous communication using data and a clock, and data is transferred in the form of serial data.

  Although not shown in the figure, the CD changer 6 includes a display unit for displaying time information and character information, an operation unit, and the like.

  The MD recorder 7 records a digital audio signal by a magnetic head 43a and an optical block 43b on an MO (magneto-optical) disk (MD) 41 housed in a jacket 40 and rotated by a spindle motor 42. is there. Of course, the MD recorder 7 has a reproduction function capable of reproducing the MD 41. However, in the configuration shown in FIG. 2, the configuration related to the playback function of the MD recorder 7 is omitted.

  An analog audio signal (usually a stereo signal) from the reproduction output terminal 30 of the CD changer 6 is supplied to the input terminal 44. This audio signal is digitized by the A / D converter 45. A digital audio signal is supplied to the signal processing circuit 46. The signal processing circuit 46 performs processing for modified DCT (referred to as ATRAC) for compressing a digital audio signal, processing for error correction coding, processing for formatting into a sector structure, processing for recording such as EFM modulation, and the like. Do.

  A recording signal from the signal processing circuit 46 is supplied to the magnetic head 43 a through the amplifier 47. A digital audio signal is recorded on the MD 41 by the magnetic head 43a and the optical block 43b. In MD41, a wobbling groove is formed in advance by embossing or the like. As wobbling information of the wobbling groove, clock information, servo information for servo of the spindle motor 42, and address information are inserted. Data is recorded in the groove. A wobbling groove reproduction signal is supplied from the optical block 43b to the controller 48. The control unit 48 extracts clock information, servo information, and address information. The data on the MD 41 is reproduced by the optical block 43b.

  A servo circuit 49 is connected to the control unit 48. The servo circuit 49 servos the spindle motor 42. Further, the focus, tracking and sled servo of the pickup composed of the magnetic head 43a and the optical block 43b are performed. At the time of recording, a position (address) to be recorded is designated using an address included in the wobbling information. The servo circuit 49 controls the positions of the magnetic head 43a and the optical block 43b so as to perform recording at a specified address given from the control block 48. In MD, data is recorded / reproduced in units called clusters.

  The memory unit 50 is connected to the control unit 48. The memory unit 50 stores information such as characters to be recorded in the management area of the MD 41 and also stores information such as characters reproduced from the management area. The data format including the MD41 management area will be described later.

  Further, interfaces 51 and 52 are connected to the control unit 48. The interface 51 is connected to the control signal input / output terminal 53. A control signal transmission path is provided between the input / output terminal 53 and the control signal input / output terminal 33 of the CD changer 6. The interface 52 is connected to a control signal input / output terminal 54. This terminal 54 is connected to the control signal input / output terminal 61 of the personal computer 1 through the converter 10.

  Transmission and reception of control signals, identification signals, and the like between the control unit 48 of the MD recorder 7 and the personal computer 1 are performed via the converter 10 and the interface 52. Further, control is performed between the personal computer 1 and the control unit 27 of the CD changer 6 via the converter 10, the interface 52, the control unit 48 of the MD recorder 7, the interface 51, the input / output terminals 53 and 33, and the interface 32. Signals, identification signals, etc. are transmitted and received.

  The personal computer 1 includes a CPU 62, a RAM 63, a ROM 64, a hard disk drive 65, a GUI 66 and an interface 67. A control signal input / output terminal 61 is derived from the interface 67, and a control signal, an identification signal, and the like are transmitted / received to / from the outside. The RAM 63 is a working memory, and the ROM 64 is a memory that stores programs and the like.

  The GUI 66 has hardware for the display 3, the keyboard 4 and the mouse 5, a graphic function for displaying windows, icons and the like on the screen of the display 3, and an operation function for selecting and determining these with the keyboard 4 or the mouse 5. Including both software and software. In the system of FIG. 1, a window 11 for displaying identification information of a plurality of songs reproducible by the CD changer 6a is presented by the personal computer 1, and a window 12 for displaying the identification information of a plurality of songs reproducible by the CD changer 6b. , And by moving the identification information of a desired song to the window 13 by dragging and dropping, the song to be recorded by the MD recorder 7 is selected. Similarly, the system shown in FIG. 2 presents a window for displaying identification information of a song that can be played by the CD changer 6, and the desired one of them is moved to another window by dragging and dropping. Select the song to record.

  In the case of the system of FIG. 1, the window presented on the display 3 of the personal computer 1 is roughly as shown in FIG. The window 11 includes a disc icon 11a for identifying a CD to be played by the CD changer 6a (identification information for C is shown in FIG. 3) and identification information for a plurality of songs in the CD in order from the top. And a song title identification display 11b. Similarly, the window 12 includes a disc icon 12a for identifying the disc (identification information E is shown in FIG. 3) and a song title identification display 12b. Similarly, the window 13 includes a disc icon 13a for identifying the MD to be recorded (identification information A is shown in FIG. 3) and a song name identification display 13b for displaying the song to be recorded.

  As shown in FIG. 3, when the ninth song displayed on the song name identification display 12b of the window 12 is to be recorded on the MD by the MD recorder 7, the mouse 5 is operated to set the cursor to the identification information. Next, this identification information is displayed at the third position of the song title identification display 13b of the window 13 by dragging and dropping. With this operation, this song is selected to be recorded. Next, in order to record the eighth song displayed on the song title identification display 11b of the window 11 on the MD, the mouse 5 is operated to position the cursor on the identification information, and then drag and drop. Thus, this identification information is displayed at the fourth position of the song title identification display 13b of the window 13. This makes it possible to select this song.

  It is possible not only to select one song at a time, but also to select all songs on one CD. That is, by dragging and dropping the disc identification information (C) of the disc icon 11a toward the disc icon 13a of the window 13, all the songs on this CD can be recorded on the MD. The same operation is performed when all songs of other CDs included in the window 12 are recorded on the MD.

  In this way, selection of a CD and music to be recorded can be performed very easily. In addition, since the display related to the CD as the signal source and the display related to the recorded MD and the song title are presented as separate windows, the entire image of the dubbing process can be clearly grasped.

  When the selection operation of the CD and the song to be dubbed from the CD to the MD by the drag and drop described above is finished, the dubbing of the song selected by the control of the personal computer 1 is started. That is, the personal computer 1 transmits a control signal to the CD changers 6a and 6b so that the selected CD and the selected music are reproduced in a specified order by the CD changers 6a and 6b. , 6b transmits a control signal to the MD recorder 7 so as to record the reproduced music.

  When the dubbing of the music information is completed, the control signal and the control signal from the personal computer 1 to the MD recorder 7 are recorded so that the MD recorder 7 records the disc identification information and the song title identification information displayed in the window 13 in the MD management area. Identification information is transmitted via the control signal transmission path. This process is automatically performed when the recording of the selected music is completed. This eliminates the need for an operation of inputting a disc name and a song title for the MD recorded by the user. However, at the end of dubbing, a display for inquiring the user whether or not to record the identification information may be presented so that the user can select it.

  The above-described embodiment of the present invention is an example of dubbing from CD to MD. However, in the case of a recording medium in which the order of songs can be changed, such as MD, song name identification of all songs recorded on MD is performed. The information may be presented in the same manner as in the window 13 of FIG. 3, and the order of the song title identification information in the song title identification display 13b may be changed by dragging and dropping. The changed result is transmitted from the personal computer 1 to the MD recorder 7, and the MD recorder 7 rewrites the information recorded in the management area to the one corresponding to the changed result. Only the management information can be operated, and it is not necessary to actually rewrite the song data recorded on the MD. In the example of dubbing described above, the order of the song title identification information can be changed in the song title identification display 13b of the window 13 by dragging and dropping before recording the selected song on the MD.

  The present invention can also be applied to control of a reproduction operation without recording. That is, medium identification information and song title identification information from two or more playback devices (CD changer, CD player, MD recorder, etc.) are presented as two windows, and each window can be dragged and dropped as in FIG. To select a desired song in a desired order. Thereafter, the playback device is controlled to play back the selected medium and song name in order. As described above, it is possible to easily control the program reproduction in which a desired music piece is reproduced in a desired order across a plurality of media. Further, in this case, the selection result presented as a window is saved by the personal computer 1 with an appropriate file name, so that a plurality of types of program playback files can be held. Thereby, the user can easily perform appropriate program reproduction according to the situation such as the time zone.

  As described above, in order for the personal computer 1 to present a window including disc identification information and song title identification information, these pieces of information relating to a previously connected device are acquired and stored in the hard disk as a table format or database. Made. An example of the format of data held in the personal computer 1 is shown in FIG.

  In FIG. 4, the category code is a code signal indicating the type of device. For example, a category code is used to distinguish between the types of devices such as a CD player and an MD recorder and to express the degree of function of the devices. The category code is transmitted from the control unit of each device to the personal computer. For example, in the case of a CD player and a CD changer, it indicates a CD player and has a CD text function (shown as CD3 in FIG. 4), a custom file function (shown as CD2 in FIG. 4), text Those having no display function (indicated by CD1 in FIG. 4) are used as category codes.

  In addition, the number of the medium to be recorded / reproduced by each device is stored. Since FIG. 4 shows an example of a CD changer, each CD changer includes a storage unit that can store, for example, five CDs, and a number corresponding to the storage position of the storage unit is stored. However, FIG. 4 shows a case where each CD changer plays one CD for simplicity. Further, the track number in each CD is stored. The track numbers are assigned in ascending order from the value of 000 to the value of the last song recorded. A title, artist information and time are stored corresponding to each track number.

  In the example of FIG. 4, data received from a CD changer having a CD2 category code, ie having a custom file function, is shown at the top. When the user inputs character information using the custom file function, the disc name and song name information as shown in FIG. 4 is downloaded from the CD changer to the personal computer and stored. More specifically, in the value field where the track number is 000, the disc name (ABC) of the CD whose CD number is 1 is stored, and the total performance time (53 minutes 20 seconds) of this disc is used as time information. It is remembered. In the value field where the track number is 001, the song name (XYZ) of the song recorded there is stored, and the performance time (4 minutes 57 seconds) of the song is stored as time information. Hereinafter, the music number and performance time information are similarly stored up to track number 014. In this case, the disc name is disc identification information, and the song name is song name identification information.

  In the example of FIG. 4, data received from a CD changer having a CD1 category code, ie, having no custom file function and CD text function, is shown in the middle. In this case, the personal computer 1 receives only the time information obtained from the TOC from the CD changer and stores it. More specifically, the value of the track number 000 field stores the total performance time (6 minutes 5 seconds) of the disc having the CD number 6 and is recorded in each track number corresponding to each track number. Information on the playing time of the music being played is stored. In this case, the total performance time is disc identification information, and the performance time of each song is song name identification information.

  In the example of FIG. 4, data received from a CD changer having a CD3 category code, ie having a CD text function, is shown at the bottom. In this case, the personal computer 1 receives the disc name, song title, and artist information from the CD changer and stores them. More specifically, in the value field of track number 000, the disc name (NMO) of the disc with CD number 2 is stored, and the total performance time (57 minutes 5 seconds) is stored as time information. Corresponding to the track number, the song name (for example, FGH), artist name (for example, cde) and performance time information (for example, 2 minutes 53 seconds) recorded in each track number are stored. In this case, the disc name is disc identification information, and the song name is song name identification information. The artist information can be used as disc identification information when there is only one artist, and can be used as song title identification information when attached to each song. Note that the data shown in FIG. 4 is preferably automatically constructed every time a device connected to the personal computer plays a medium such as a CD.

  A more specific example of the window described with reference to FIG. 3 will be described. 5 is an example of a window used as the window 11, FIG. 6 is an example of a window used as the window 12, and FIG. 7 is an example of a window used as the window 13. These windows are simultaneously displayed on the display of the personal computer as in the case of FIG.

  In the window shown in FIG. 5, the CD changer 6a plays a CD text CD, stores CD text information, and the personal computer 1 receives the CD text information and stores it in the format shown in FIG. belongs to. The window formats of FIGS. 5, 6 and 7 are similar to each other. A song title identification display 76 of the window is presented, and operation icons 71 corresponding to the operation buttons of each device are presented on the left side. The operation icon 71 includes a plurality of button displays having the same shape as the operation buttons of the CD player and the MD recorder.

  In the window shown in FIG. 5, the CD number is displayed above the operation icon. On the upper side of the song name identification display 76, a device icon 73 indicating the type of device, a disc name 74, and an artist name 75 are displayed. The window of FIG. 5 corresponds to the data in which the category code in FIG. 4 corresponds to CD3.

  FIG. 6 is an example of a window presented by data (category code or CD1 in FIG. 4) formed based on the TOC from the CD changer 6b. Since the CD changer 6b does not have the functions of a CD text and a custom file, the performance time is displayed corresponding to each song.

  Then, the song title identification information displayed in the windows of FIGS. 5 and 6 is sequentially copied into the window shown in FIG. 7 by drag and drop operations. In the window corresponding to the MD recorder 7 of FIG. 7, a power button 71a and a record button 71b are displayed as operation icons. In addition, a plurality of editing icons 71c to 71g for editing in units of music are also displayed below the operation icon 71.

  The icon 71c is an icon for instructing movement of a song. The order of songs can be changed by the icon 71c. The icon 71d is an icon for instructing division of music. The icon 71e is an icon for instructing the combination of two songs. The icon 71f is an icon for instructing deletion of a part of the song. The icon 71g is an icon for instructing deletion (erasing) of a song. Using these editing icons, editing can be performed on a plurality of songs presented as the window of FIG.

  Further, a state immediately after the identification information (BDY) of the track having the track number 0010 in the window in FIG. 5 is moved to the position of the track number 006 in FIG. 7 by drag and drop operations is shown. In this case, the display color of the position (row) corresponding to the selected song in FIG. 5 is changed or blinked. This clearly indicates to the user that the track number 0010) has been selected.

  On the other hand, in the window shown in FIG. 7, the selected song name is displayed in the track number 006, and the performance time is 0 minute 0 seconds. That is, it is indicated that the selection of music has been completed but recording has not been completed. Further, as indicated by 79 in FIG. 7, a recordable time is displayed above the song title identification display. The recordable time display 79 sets the total recording time of the MD as 100%, and displays the ratio of the total performance time of the already selected and recorded music in a bar shape. In this bar-shaped display, portions having different colors, densities, and the like are provided. This means a portion that increases when the selected song is recorded with respect to the already recorded song. Therefore, the recordable time display 79 shows how much the MD recording time increases or decreases when the music is selected.

  When the selection of a song is completed by the drag and drop operations using the GUI, the song enters a standby state for dubbing. By giving an instruction to cancel the pause by clicking the record button 71b in the operation icon 71 or clicking the pause button, the CD changer reproduces the selected song, and the MD recorder records this song. During recording, the recording button 71b changes to “NOW REC”, for example, indicating that the dubbing operation is in progress. Not only the selection, reproduction, and recording processing for each song, but also the songs may be recorded together after the selection operation is completed.

  After recording the selected song (after recording one song or all songs), the disc identification information and song name identification information displayed in the window are automatically displayed in response to the completion of recording. Is transmitted to the MD recorder together with the control signal, and is recorded in the MD management area by the MD recorder. Preferably, a display indicating that text information is being recorded is displayed. Therefore, it is not necessary to input characters or the like to the MD again after dubbing. Further, when the selected music is not accompanied by character information, the music name can be recorded on the MD by inputting the character of the music title by operating the keyboard of the personal computer or the like and then recording it. The disc name can also be entered using a personal computer.

  The above-described music editing work relating to MD and recording of character information on the MD are performed by operations on data in the MD management area. The data in the MD management area will be described below. A U-TOC area for recording the U-TOC is arranged on the inner periphery side of the MD recordable area, and information related to each program recorded in the program area is recorded. In the lead-in area, P-TOC is recorded in advance as pre-pits. The P-TOC stores the start address and end address of each song on the disc, the track name that is the name of the song, the disc name that is the name of the disc, and the like.

  In order to perform the recording / reproducing operation on the MD, it is necessary to read in advance management information (that is, P-TOC and U-TOC) recorded on the MD. That is, these pieces of management information are read when the MD is mounted, stored in storage means such as a DRAM, and referred to in subsequent recording / reproducing operations. Further, the U-TOC is edited and rewritten according to data recording or erasing. Each time a recording / erasing operation is performed, editing processing is performed on the stored U-TOC. Then, the U-TOC updated as a result of the editing process is written into the U-TOC area of the MD at a predetermined timing.

  U-TOC is inventory information for managing each program recorded in the program area. The U-TOC area is composed of 32 sectors, for example. Hereinafter, sector 0, sector 1, sector 2, and sector 4 will be described. Sector 3 and sectors 5 to 32 are extended areas and are not used at this stage. First, in sector 0, the start address, end address, copy protection information, emphasis information, etc. of each program are managed. FIG. 8 shows a configuration example of the sector 0. Sector 0 and sector 1, sector 2 and sector 4 which will be described later have a size of 2352 bytes, and are configured by arranging 588 4-byte slot units. Numbers 0 to 587 are assigned to distinguish the 4-byte slot units. Cluster H and cluster L indicating a predetermined address position following the header portion, manufacturer code and model code indicating the manufacturer and model of the disk, First TNO and Last TNO indicating the first and last program numbers, sector usage, disk serial number, In addition, the disk ID and the like are recorded in order.

  In addition, a P-DFA (Pointer for Defective Area) indicating the head position of a slot for storing information related to the position of a defect generated on the MD, a P-EMPTY (Pointer for Empty slot) indicating the use status of the slot, recordable Corresponding configuration composed of P-FRA (Pointer for FReely Area) as the head position of the slot managing the area and P-TNO1, P-TNO2... P-TNO255 indicating the head position of the slot corresponding to each program number. A table instruction data portion is recorded.

  Numbers 78 to 587 are provided with 255 slots as described above for storing information relating to the positions of defects generated on the disk. Each slot is composed of 4 bytes, and a start address, end address, track mode, and link information are managed in one slot.

  By the way, the MD apparatus to which the present invention can be applied does not necessarily have to record data sequentially on the recording medium MD, and can correctly reproduce the data recorded discretely on the recording medium. Is. A process performed with reference to the P-FRA in the sector 0 of the U-TOC described above in order to correctly connect the discretely recorded data will be described. FIG. 9 is an example showing a case where 03h (h means a hexadecimal number) is recorded in the P-FRA. In this case, first, the slot 03h is accessed as shown in FIG. 9A. The start address and end address data recorded in the slot 03h indicate the start and end addresses of one part recorded on the disc.

  The link information recorded in the slot 03h indicates the address of the slot to be followed. In FIG. 9A, this address is 18h. Therefore, the slot 18h is accessed as shown in FIG. 9B. Since the link information recorded in the slot 18h indicates that the address of the slot to be followed is 1Fh (FIG. 9B), the slot 1Fh is further accessed (FIG. 9C). Then, the slot 2Bh is accessed according to the link information of the slot 1Fh (FIG. 9D), and the slot E3h is accessed according to the link information of the slot 2Bh (FIG. 9E). In this way, the link information is successively traced until null (that is, 00h) appears as link information.

  By following the link information in this way, the addresses of data discretely recorded on the MD are recognized in order. By controlling the optical pickup and sequentially accessing these addresses on the MD, it becomes possible to connect discretely recorded data.

  The above description relates to processing for combining data recorded discretely with reference to P-FRA, but P-DFA, P-EMPTY, P-TNO1, P-TNO2,... P Similarly, data recorded discretely can be combined with reference to TNO255.

  Next, in the sector 1 of the U-TOC area, the title of each program and the title of the entire MD1 are managed. Here, the title of the entire MD is information such as an album title and a player name when the recorded program is audio data, and the title of each program corresponds to a song name or the like. FIG. 10 shows an example of the configuration of the U-TOC sector 1.

Character information of each program, the corresponding table instruction data P-TNA _X (X is 1 to 255) is recorded in the character table of the slot indicated by, if the number of characters is large, using the link information Recording is performed by connecting a plurality of slots. Further, in this U-TOC sector 1, since usable character codes are defined, alphabetic titles that are mainly input with alphabetic characters are managed. However, when the user instructs katakana input, a special code “^” is automatically generated and managed in sector 1 by enclosing alphabet characters. In such a case, the alphabet surrounded by the special code "^" is converted into katakana based on the conversion table and displayed. For example, the character ^ a ^ is converted into Katakana characters by the conversion table.

  Further, an example of sector 2 is shown in FIG. Sector 2 manages the recording date and time for each program recorded in program area 47. An example of sector 4 is shown in FIG. The title of each program recorded in the program area 47 can be expressed in kanji, hiragana, or katakana according to the character code determined to be used in the sector 4.

  In the present invention, MD is used as a recordable medium. However, the present invention is not limited to this, and other types of optical disks (for example, DVD (digital video disk), magnetic tape, optical tape, semiconductor memory, etc.) are used. In addition, the digital information recorded on the recording medium is not limited to audio data but may be video data, etc. The present invention uses a personal computer as a control device. You may make it comprise as this control apparatus.
