However, as the TOC information of the lead-in area, the track number of the area 21 is fixed to "00h", the index portion 152 of FIG. 18 is set to the point area 22, and each of the minute component, the second component, and the frame number of the elapsed time. Areas 23, 24,
Each of the numerical values of 25 is fixed to "00h".

That is, the first management information 11 in the lead-in area is the same as the conventional TOC information in the CD.
The content of the point area 22 indicates the number of recorded programs of the programs recorded in the recording area, the total recording time, and the address corresponding to each recording program.
When the value is "A0h" in hexadecimal notation, the content PMIN of the absolute time minute component area 27 indicates the first movement number or song number, and when the content POINT of the area 22 is "A1h", the content PMIN of the area 27 Indicates the last movement number or song number, and when the content POINT of area 22 is "A2h",

There are advantages. In addition, as the character information, for example, a disc title or album name, a disc ID, a performer, etc. are recorded so that it can be used when selecting a plurality of vehicle-mounted or home-use changers or operating FM teletext. You can

In a conventional normal CD, for example, in the case of 14 songs, the above-mentioned time information is duplicated nearly 700 times as TOC information of the lead-in area of the inner circumference. In the embodiment, the number of times of duplication is reduced to half and the character data is recorded in the surplus portion. Therefore, it is not particularly necessary to develop a new LSI or the like, and the character information can be read by merely changing a part of the software program for displaying the reproduction time. Further, future expandability can be ensured without affecting the R to W channels of the subcode or the main recording part other than the subcode of the lead-in area. Furthermore, if the conventional disc reproducing apparatus has a text display function, the character information of this embodiment can be displayed with almost no increase in cost.

Here, to give a concrete example of the character information standard of the present embodiment, the recorded contents include an album name, a performer, a disc ID such as a disc serial number, a genre indicating a music type or field, and the like. It is an additional information size indicating the size of the text information, the publisher, and, as an option, a total of 13 items including each song name, composer, lyricist, arranger, production date, other 1, and other 2. I am trying. There are four types of characters, which can be managed by country code as an option, and the number of characters can be expanded up to 224 bytes per item and up to 672 bytes as an option. Character reading speed is 262
Bytes / second. In addition, the binary code information ID1 to ID5 in the areas 31 to 35 can be used for expansion, and reproduction control and multilingualization are possible.

Next, each item of the recorded contents will be described in more detail.

FIG. 3 shows one block when the item is “size”, and the areas 31 to 39 correspond to the areas 31 to 39 of FIG. 2B, respectively.

In FIG. 3, in the binary code information ID1 of the area 31, the most significant bit (MSB) 341 is used as the final text block flag, and when this MSB 341 is "1", a continuous block of one item. Will be the final block of. Since the item of "size" in FIG. 3 is composed of one block, this block is the final block and the MSB 341 is "1". The 7-bit portion 342 following this is used as an item code (Contents ID) for identifying each item,
For example, it is set as shown in FIG.

That is, FIG. 4 shows the hexadecimal notation value of the content of the 7-bit portion 342 of the binary code information ID1 of FIG. 3 and the corresponding items, and the content of the 7-bit portion 342 is " When "00h", the item of "size" is indicated. When the content of the 7-bit portion 342 is "01h to 63h", that is, a decimal number 1 to 99, it indicates that the item is a "song name" corresponding to the track number or the song number. Similarly, "64h"
Is "disc ID / sales source", "66h" is "genre code / text", "67h" is "date (manufacturing date) / country code", "68h" is "album name",
"69h" is the "performer", "6Bh" is the "composer",
“6Ch” indicates each item of “lyricist” and “6Dh” indicates each of “arranger”. Furthermore, "70h-7F
As will be described later, “h” is used to extend the number of consecutive blocks of the items “68h to 6Fh”.
In the case of the last block of the continuous block of one item, the MSB of the binary code information ID1 in FIG. 3 above.
Since 341 becomes “1”, as the 8-bit binary code information ID1, “6xh” becomes “Exh” and “7xh” when x is an arbitrary one-digit hexadecimal number (x = 0h to Fh). “Becomes“ Fxh ”.

Returning to FIG. 3 again, the above item is "size".
In the case of, since it is completed in one block, the binary code information ID1 of the area 31 is "80h". In the next area 32, the upper 3-bit portion 343 is used as a character code, and the lower 5-bit portion 344 is used as a content serial number. As the character code of the 3-bit portion 343, for example, "000" in binary is ASCII.
I code, "001" is European character code including special characters, "010" is Katakana JIS code, "01"
1 ”indicates a shift JIS 2-byte code,
When it is "1xx", the character corresponding to the country code when the item code is "67h" is adopted. The content serial number of the 5-bit portion 344 represents a serial number of a maximum of 32 blocks of 0 to 31 per item. Therefore, since the text data in one block is 7 bytes, a maximum of 32 blocks can record 224 (= 7 × 32) bytes of characters.

The next area 33 in FIG. 3 shows the number of items, which is "06", that is, six kinds in this example. This number of items does not include the item of "song name", but it may be included. The following areas 34 to 37 show the number of blocks used for each item of "size", "album name", "performer", and "song name". In the example of FIG. "75", "04",
It is "03" and "62" (block). The “size” of the area 34 is the number of blocks of all items,
"Disc ID / Distributor" item and "Genre Code /
The number of blocks for each item of "text" and "date / country code" is also included, so it is larger than the total number of blocks for each item of "album name", "performer", and "song name". .

Further, the next two areas 38 and 39 show the state of expansion. Corresponding the 8 bits of each byte to the expansion state of 8 items, "1" is set when being expanded. There is. That is, for items whose item code of the 7-bit portion 342 of the binary code information ID1 of the area 31 is "68h to 6Fh", a maximum of 32 per item represented by the content serial number of the 5-bit portion 344.
When it is desired to record the text beyond the block, by setting the item code of the 7-bit portion 342 to "70h to 77h", it is possible to further expand the 32 blocks.
For example, when the album name with the item code “68h” is extended to 32 blocks or more, the item code is set to “70h” from the 33rd block, and further 32 blocks can be consecutively used to use a maximum of 64 blocks. . At this time, "1" is set to the corresponding bit of the 8 bits of the area 38. Further, when it is desired to record the text in more than 64 blocks, by setting the item code of the 7-bit portion 342 to "78h to 7Fh", the text can be continuously recorded in 32 blocks and a maximum of 96 blocks. it can. At this time, "1" is set to the corresponding bit of the 8 bits of the area 39. Like this, 2
By expanding the number of times, it is possible to record a maximum of 96 blocks, that is, a maximum of 672 bytes, which is 7 bytes per block. Areas 38, 39
If both are "00h", it means that the extension has not been performed.

Next, with reference to FIG. 5, an example of recording the character information of the item “album name” will be described. This includes other items such as "Disc ID / Publisher", "Genre Code / Text", "Date / Country Code", "Performer", "Composer", "Lyrics", and "Arranger". The same applies to the case.

In the example of FIG. 5, the item code of the 7-bit portion 342 of the binary code information ID1 of the area 31 is "6".
Since it is an "album name" of 8h "and is completed in one block, the final text block flag of MSB341 becomes" 1 ", and the binary code information I
The eight bits of D1 are "E8h". The contents of the binary code information ID2 in the area 32 are the ASCII code in which the character code of the 3-bit portion 343 is “000”, as in the example of FIG.
The content serial number is "00000".

In principle, the next area 33 and subsequent areas are assigned to text characters, but in the first block of one item,
Only the area 33 is used as an auxiliary control area, the 8-bit most significant bit 345 is a copy inhibition flag, the next 2-bit portion 346 is a character type, and the lower 5-bit portion 347 is a final serial number. When the copy prohibition flag of the most significant bit 345 is "1", copying of text characters is prohibited, and in the example of FIG. 5, "0" indicates that copying is permitted. Two
The bit portion 346 indicates the number of types of characters used in this item, and when "00", one type can represent up to four types of "11". If the blocks are different, a plurality of character codes in the series of character strings, but up to four types are allowed, and the character code of each block is designated by the 3-bit portion 343 in the binary code information ID2. . This makes it possible to reduce the total number of blocks when kanji and alphanumeric characters are mixed. 5 on the lower side
The final serial number of the bit portion 347 indicates the content serial number of the final block of the continuous blocks that form the series of character strings, and is 0 in this example because one block is completed. The area after the next area 34 is used for a text character, and FIG.
In the example, the character string “ABC” is described. The area of the remaining bytes in the block is the so-called null code "0.
It is filled with 0h ".

Here, the item code is "64h",
"66h", "67h""Disc ID / Publisher",
"Genre code / text", "date / country code"
For each item, 3 blocks, 21
It is stipulated to complete within a byte. "66
About the item of "genre code / text" of h ",
As the genre code, for example, "05h" is classic, "17h" is rock, etc., and the genre is defined in correspondence with a 1-byte code, and it is not sufficient to predefine the genre. In addition, "," and 20 bytes of character text can be added in succession to the 1-byte code. The "date / country code" of "67h" is, for example, ASCII characters, and is "Y".
"YYYMMDD / US" such as 4 digit year (Y), 2 digit month (M), 2 digit day (D), and 2 letters country code (Country Code) The country code is, for example, in accordance with ISO (International Standard), US in the United States, JP in Japan, and NL.
Is represented as in the Netherlands (Netherland). The date usually indicates the date of manufacture, but if it is unknown, use English letters "mmdd"
Fill in.

Next, the item of "song name" as information for each piece of music, which is a program in the recording area, will be described with reference to FIG.

FIG. 6 shows one block in the case of the item “song name”. The formats of the binary code information ID1 and ID2 in the areas 31 and 32 are the same as those in FIG. 3 and FIG. 31 binary code information ID1
7-bit portion 34 on the lower side shown in FIG. 3 and FIG.
The item code of 2 is a numerical value of 1 to 99 indicating a music number or a track number, that is, "01" in hexadecimal notation.
h to 63h "are written. In the final block of the series of blocks in which the song title text information of one song is continuously recorded, the most significant bit (MSB) of the binary code information ID1 in the area 31 is" 1 ". Therefore, the entire 8-bit ID1 is “81h to E3h”.

The following area 33 in the block is assigned to the text character data, but three areas 33 to 35 are assigned to the first block of the continuous block for one music piece.
Is assigned to the following binary code information.
That is, the area 33 is similar to the area 33 of FIG.
It is used as an auxiliary control area, and the most significant bit 345 of this 8-bit area is the copy prohibition flag and the next 2-bit portion 346.
Is assigned to the character type, and the lower 5-bit portion 347 is assigned to the final serial number. The next area 34 is a genre code area, similar to the genre code in the item "genre code / text" of "66h" described above, for example, "05h" is classic, "17h" is rock, etc. A 1-byte code indicating the genre of each song is recorded. If the genre of the song is the same as the genre of the album indicated by the item of "genre code / text", the genre code is set to "00"
It may be represented by a specific code such as. In the next area 35, as a reproduction control area, information used for surround processing at the time of reproduction and reproduction signal processing such as low-frequency boost, equalizer pattern, and volume level is recorded.

In the example of FIG. 6, the music title is “ABC” and three characters, the areas 36 to 38 are used, and the remaining area 39 is filled with “00h”. In this example, since the character string of the music title is completed within one block, the final serial number of the lower 5-bit portion 347 in the area 33 is "00000".

Next, FIG. 7 shows a concrete example of the text character string of the first music piece of the above-mentioned "song title" item. In FIG. 7, five blocks are used for the text character string of the first music, and the binary code information I in the area 32 is used.
"00000" as the serial number of the lower 5 bits of D2
0 to “00100” are recorded. Areas 33, 34, and 35 of the first 0th block BL _T0 are used as the auxiliary control area, genre area, and reproduction control area, respectively. In the example of FIG. 7, as the auxiliary control information of the area 33, the copy inhibition flag of the most significant bit described in FIG. 5 and FIG. 6 is “0” indicating that copying is possible, and the character type of the next 2-bit portion is 1 The type is "00", the final serial number of the lower 5 bit portion is 4, and the auxiliary control code of this area 33 is "04h". The genre of the first piece of music is classic, and the genre code of the area 34 is "0.
5h ", there is no particular reproduction control, and the reproduction control code of the area 35 is" 00h ". The text character string indicating the music title is started to be recorded from the area 36 of the 0th block BL _T0 . In the example of No. 7, "PIANOspCON
CERTOspINspAspMINOR, Op. The character string "6" (where "sp" represents a blank space) is the block BL _T0 ~
It is sequentially recorded in the text area of BL _T4 . The remaining areas 38 and 39 of the final block BL _T4 are filled with a so-called null code “00h”. Since the MSB of the area 31 of the final block BL _T4 of the first song is “1”,
The 1-byte binary code information ID1 in the area 31 is
It is expressed as "81h". 2 from the next block BL _T5
The song title item information after the song is similarly recorded. In the area 33 of the first block BL _T5 of the second piece of music in FIG. 7, the copy prohibition flag of the most significant bit described in FIG. 5 and FIG. 6 is set to “1” and one character and one byte of auxiliary control The code is "85h".

In the example of FIG. 7, only the character information, that is, the block of the second management information is extracted and shown in order to simplify the illustration. However, when recording in the lead-in area of the disc. As described with reference to FIG. 1 above, the first management information 11 which is mainly time information,
It goes without saying that the second management information 12, which is mainly character information, is alternately recorded every three blocks.

Here, some points to be noted in the standard of the character information as the second management information will be described.

When a 2-byte code such as Kanji is used, it is preferable that the 2-byte code character is not spread over two blocks. That is, the 2-byte code should not start from the area 39 at the end of one block. In this case, when a 2-byte code such as a Chinese character is made to continue in the next block, the area 39 is basically set to the null code "00h" so that the area 33 is started from the first area 33 for the text characters of the next block. This ensures that double-byte characters always have meaning from the beginning of the block. Null code “00h” or odd 1 byte code in the character string may be ignored and packed. The final judgment of the character string is whether the MSB of the binary code information ID1 in the area 31 is “1” or not. To do.
Further, whether or not the character string is expanded beyond 32 blocks is determined by the expansion state information of the areas 38 and 39 of the block of the item of the size shown in FIG.

Among the above items, the performer ("69
h ”), composer (“ 6Bh ”), lyricist (“ 6C
h ”), arranger (“ 6Dh ”), etc. are different, in order to distinguish them, in the character string of each item, the name of the composer or performer is followed by“ ^ 15 ^ ” When there is a description, it means that it is the name of only the 15th song. Further, when the description "^ 5: 10 ^" follows the name, it means the name of the fifth song to the tenth song. Furthermore, if "^ 5 :: ^" follows the name, it means the name from the fifth song to the end. In this way, the song number can be identified in the series of character strings. In this case, it is preferable not to display the characters surrounded by "^^".

Further, although there are four types of character codes, it is preferable to notify the user of this when all cannot be displayed due to hardware restrictions. For example, a display such as "Can't Display" may be displayed.

Next, the second including the character information as described above
Of the disc management apparatus for reproducing a disc such as a CD recorded in the lead-in area with the first management information including the time information, in particular, a specific example applied to a so-called optical disc reproducing apparatus with an autochanger function. , Will be described with reference to FIG.

In FIG. 8, a plurality of optical discs 41 such as CDs are read by a desired changer by the auto changer function.
It is possible to play by selecting a sheet. The optical disc 41 selected by the changer function is rotationally driven by the spindle motor 43, and the recorded contents are optically read by the optical pickup 42. The signal from the optical pickup 42 is sent to a signal processing circuit 45 for digital processing via an RF signal processing circuit 44. The digital audio signal component from the signal processing circuit 45 is subjected to sound field processing such as reproduction of various sound fields by the sound field processing circuit 46, and converted into an analog audio signal by the D / A (digital / analog) converter 47. It is converted and taken out from the analog audio signal output terminal.

In the signal processing circuit 45, the above-mentioned subcode signal is taken out, and the subcode R and W separation circuit 48 separates the data of the subcodes R to W,
The graphic display circuit 49 extracts the graphic display output signal. This follows the so-called CD-G (graphics) standard.

Further, the Q-channel data of the sub-code signal extracted from the signal processing circuit 45 is separated by the sub-Q separation circuit 51, and the time information processing circuit 52 and the second management information processing circuit 54. Sent to.
The time information processing circuit 52 sends the time information obtained from the first management information to the time display section 53 to display the time. The second management information processing circuit 54 has information on each item obtained from the above-mentioned second management information, for example, genre information 55a, copy information 55b, reproduction control information 55d,
The character information 55d such as the album name and the player name, the size information 55e, etc. are taken out.

The character information 55d separated by the second management information processing circuit 54 is sent to the character content separation circuit 57,
The display items and contents are selected and separated according to the operation of the display contents switch 56, etc., and are sent to and displayed on the character display unit 58. The genre information 55a separated by the second management information processing circuit 54 is the control circuit 6 using a so-called CPU or the like.
Then, the control is performed so that only the disc or song of the genre designated by the user is played back. A RAM 61 such as a semiconductor memory is connected to the control circuit 60, and genre information designated by the user operating the genre switch 62 is stored in the RAM 61.
This designated genre information is the second management information processing circuit 5
It is determined whether or not the genre information 55a from 4 matches, and only when they match, the servo circuit 65 is controlled to perform the disc reproducing operation. In the autochanger type, the playback control is performed only for the discs of the same genre while automatically exchanging the discs, so that only the discs of a specific genre can be selectively reproduced. The reproduction control information 55d separated by the second management information processing circuit 54 is sent to the sound field processing circuit 46, and sound field processing such as low-frequency enhancement and reproduction volume control are automatically performed.
This can be done for each song. The copy information 55b from the second management information processing circuit 54 permits or prohibits the copying of the text character information for each song. This copy information 55b may be sent to the control circuit 60 to control the transfer of the text character string to the outside, for example. Also,
The size information 55e from the second management information processing circuit 54 is
The data is sent to the TOC read waiting time processing circuit 64. The TOC read waiting time processing circuit 64, based on the sub-Q error information 63 indicating whether or not the data of the sub-code Q channel is normally read by the signal processing circuit 45, and the size information 55e. The time required to read all the second management information, that is, the waiting time is calculated and sent to the time display unit 52. The display of the waiting time may be performed by the character display unit 58.

Next, a specific example of the operation for displaying the album name will be described with reference to FIG.

In the first step S71 of FIG. 9,
The Q channel data of the subcode is separated while confirming the error detection by CRC for each block.
In the next step S72, the value A of the address area 17 is

73, and if NO, the process proceeds to step S81. In step S81, each detected address value ADR
According to the above, the reading process of the time information and the copyright code is performed. In step S73, the area 31 in FIG.
It is determined whether or not the item code of the lower 7-bit portion of the binary code information ID1 of is "68h" corresponding to the album name. If YES in step S73, the process proceeds to step S74, and if NO in step S73, the process proceeds to step S82. In step S82, the selection / separation process is performed for items other than the item code "68h".

In step S74, it is determined whether or not the MSB (most significant bit) of the binary code information ID1 is "1", that is, whether or not it is the last block, and YE
If S, the process proceeds to step S83, and if NO, the process proceeds to step S75. In step S83, it is determined whether or not the block having the content serial number 0 of the lower 5 bits of the binary code information ID2 in the area 32 has already been read, and NO.
If so, the process proceeds to step S75, and if YES, the process proceeds to step S77. In step S75, it is determined whether or not the content serial number of the binary code information ID2 of the current block is 0. If YES, the process proceeds to step S76 and NO.
If so, the process proceeds to step S77. Step S76
Then, since the current block is the first block of the series of character strings, the copy inhibition flag, the character type, and the last serial number which are the auxiliary control information of the area 33 of FIG. 6 and the genre code of the area 34 are Then, the data of 3 bytes including the reproduction control information in the area 35 is read and stored in the memory.

In step S77, the character code and the content serial number of the binary code information ID2 in the area 32,
The text character strings in other areas are sequentially read and stored in the memory, and the process proceeds to step S78. In step S78, it is determined whether or not all the character strings of the current song title have been stored. If NO, the process returns to step S71 to process the next block, and if YES, step S79.
Proceed to and display the album name.

Next, the operation for displaying the waiting time based on the size item information will be described with reference to FIG.

In the first step S86 of FIG. 10, a variable M indicating the number of times of re-reading when reading all the second management information is set to 0, and an error number E is set to 0. In the next step S87, the Q channel data of the subcode is separated, an error is detected by the CRC for each block, and if there is an error, the error number E is added. In the next step S88, it is detected whether or not the value ADR of the address area 17 is "6", the process proceeds to step S89 if YES, conversely the process proceeds to step S81 if NO. In step S81, the time information and the copyright code are read out according to each of the detected address values ADR. Step S8
9, the binary code information I in the area 31 of FIG.
The item code of the lower 7-bit part of D1 is "size"
It is determined whether or not "00h" corresponding to. When YES at step S89, control proceeds to step S90, where NO.
If so, the process proceeds to step S84. In step S84,
The selection / separation process is performed for items other than the item code “00h”.

In step S90, it is determined whether or not the content serial number of the lower 5 bits of the binary code information ID2 in the area 32 is 0. If NO, the process returns to step S87, and if YES, to step S91. It is progressing. In step S91, the total number of blocks N written in the size information (ID4) of the area 34 in FIG. 3 is stored in the memory, and the total number of blocks / 75 is doubled, that is, 2 × N / 75 is calculated. After storing the answer as X,
It proceeds to step S92. This is because the reproduction time per block is 1/75 second, and the first management information and the second management information are written alternately every three blocks, which takes twice the time. The waiting time X is calculated as a time that is twice the number of blocks of the management information of 2.

In step S92, it is determined whether or not an error has occurred while storing the block information, and NO.
If so, the process proceeds to step S93, and if YES, the process proceeds to step S95. In step S93, the calculated waiting time X seconds is displayed, but it is not displayed when X <2, that is, the waiting time is shorter than 2 seconds. And X
After a second, the waiting time display is turned off and the following processing is performed. In the next step S94, it is determined whether or not all blocks have been read. If YES, the process ends, and if NO, the process returns to step S87.

In step S95, considering that the above error has occurred and re-reading is necessary,
2X seconds obtained by doubling the above X is displayed as the waiting time, and after 2X seconds, the waiting time display is turned off and the next processing is started. In the next step S96, it is determined whether or not reading of all blocks is completed. If NO, the process returns to step S87, and if YES, the process proceeds to the next step S97. In step S97, 1 is added to the reread count M, and in the next step S98, it is determined whether or not M is 2 or more. If YES, the error is abnormally large, so the process proceeds to step S99 to perform another process. If NO, the process returns to step S87.
