如上所述,在调制信号送出装置100中,虽然根据需要参照追记关联信息410,但是处于与传统同样的调制处理生成调制信号。 As described above, when the modulation signal sending apparatus 100, although the write-once information 410 related Referring required, but at the same modulation with the conventional process generates a modulated signal. 根据该调制信号基制作光盘340。 Creating a disc 340 based on the modulation signal group. 追记装置200中,根据追记关联信息410 或调制数据,算出记录追记信息420的区域并记录追记信息420。 Writing apparatus 200, 410 according to the write-once-related information or modulated data, calculates the write-once information recording area 420 and the 420 write-once information recording. 由于追记信息420可任意设定,因而可以向传统的调制方式的已记录光盘输入个别的识别信息。 Since the write-once information 420 can be arbitrarily set, it is possible to traditional modulation scheme recorded disc input individual identification information. 这样,可以向已记录的光盘记录以前难以实现的识别信息等的追记信息,可扩展光盘的用途。 Thus, the identification information may be recorded or the like is difficult to write-once information previously recorded onto the optical disc, the optical disc may be extended use.

另外,由于追记的追记信息用传统的格式记录,因而不必进行重放机(播放器、驱动器等)的改造和特殊电路就可以进行读出。 Further, since the recordable write-once information is recorded in a format with the conventional, it is not necessary for playback machine (player, a drive, etc.) and special transformation circuit can be read out. 而且,不必改变现行的光盘生产的工序,通过追加追记装置可进行追记。 Further, the optical disc without changing the existing production process may be carried out by adding a write-once recordable device.

以下,以CD的例说明具体的追记信息的记录方法。 Hereinafter, the embodiment described CD recording method of the write-once information specific. 第2图表示CD 的l帧的数据结构。 FIG 2 shows the data structure of the CD frame l. CD中,从2信道的数字音频数据的合计12个样本(24 符号)形成各4符号的校验分量Q及校验分量P。 The CD, a total of 12 samples from the two channels of digital audio data (24 symbols) formed in each of the four parity symbols Q components and parity components P. 向该合计的32符号附加子码的1符号而形成33符号(264数据比特),以之为一组进行处理。 To the total 32 symbols 1 symbol of subcodes formed by an additional 33 symbols (264 data bits) to be processed as a group of. 即,EFM调制后的1帧内,包含由l符号的子码、24符号的数据、4符号的Q校验分量、4符号的P校验分量组成的33符号。 That is, one frame after the EFM modulation, the symbols comprising the subcode l 33 symbols, data of 24 symbols, Q parity symbols of the components 4, P parity symbol consisting of 4 components.

EFM中,各符号(8数据比特)变换成14信道比特。 EFM, each symbol (8 data bits) is converted into 14 channel bits. EFM调制的最小 EFM modulation minimum

反相间隔(记录信号的l和l之间0的个数成为最小的反相间隔)Tmin为3T,与3T相当的凹坑长成为0. 87 jum。 Inverse interval (number between 0 and l l recording signal becomes minimum inverting interval) of Tmin is 3T, and 3T long pit becomes quite 0. 87 jum. 与T相当的凹坑长为最短凹坑长。 T pit and a considerable length of the shortest pit length. 最大反相间隔(记录信号的1和1之间0的个数成为最大的反相间隔)Tmax为llT。 The maximum inverting interval (the number of recorded signals between the 1 and 0 of the maximum inverting interval becomes 1) to Tmax of llT. 另外,即使是14比特相互连接时,为了满足上述的Tmin=3T、 Tmax-11T的游程长度制约条件,各14信道比特之间配置有3比特的容限比特(也称连接比特)。 Further, even when the bit 14 is connected to each other, in order to satisfy the above Tmin = 3T, Tmax-11T runlength constraint, each of 3 bits 14 are disposed between the channel bit margin bits (also referred to as connection bits). 作为容限比特,预备了(OOO)、 (001)、 (010)、 (100)的4种图案。 As the margin bit, the preparation (OOO), (001), (010), (100) four types of patterns. 而且,帧的开头附加帧同步图案。 Further, the head frame of the additional frame synchronization pattern. 令信道比特的周期为T时,帧同步图案是11T、 11T及2T连续的图案。 So that the channel bit period is T, the frame synchronization pattern is a 11T, 11T and 2T continuous pattern. 由于这样的图案根据EFM调制规则不会产生,因而通过特异的图案可检测帧同步。 Since such a pattern does not occur according to the EFM modulation rule, and thus detectable by a specific pattern of the frame synchronization. l帧是由总比特数588信道比特组成的。 l is the total number of bits of the frame 588 channel bits. 帧频率设为7. 35kHz。 The frame frequency is set to 7. 35kHz.

98个这样的帧的集合称为子码帧(或子码块)。 Such a collection of 98 frames is referred to as subcode frame (or sub-code blocks). 重排98个帧以在纵方向上连续并显示的子码帧由识别子码帧的开头的帧同步部、子码部以及数据及校验分量部组成。 Rearrangement subcode of 98 frames in the longitudinal direction of the continuous frames and displays the beginning of the subcode frame identified by the frame synchronization portion, a sub code portion and a data portion and a checksum component composition. 另外,该子码帧与通常的CD的重》欠时间的l/75秒相当。 Further, the sub code frame and the weight of a normal CD "less time l / 75 seconds considerable.

该子码部由98个帧形成。 The sub-code portion is formed of 98 frames. 子码部中的开头的2帧都是子码帧的同步图案,同时也是EFM的违规(out of rule)的图案。 In the subcode portion 2 are the beginning of the subcode frame sync pattern, the EFM also illegal (out of rule) pattern. 另外,子码部中的各比特分别构成P, Q, R, S, T, U, V, W信道。 Additionally, the bits in the subcode portion constitute P, Q, R, S, T, U, V, W the channel.

接着,依次说明本发明的追记信息的记录方法的几个示例。 Next, sequentially illustrate several exemplary write-once information recording method of the present invention.

第l追记信息的记录方法是,在调制信号送出装置中进行信息数据的调制时,生成在调制信号的任意区间设有无调制区间的调制信号并制作光盘,在追记装置中向无调制区间记录追记信息的方法。 L write-once information recording method is that when the modulated information data modulated signal feeding means, is provided without generating a modulation signal modulating interval modulation signal in an arbitrary interval and create the disc, the non-modulated in the write-once recording apparatus section the method of write-once information.

第3图说明本发明的第1追记信息记录方法。 3, FIG. 1 explained recording method of the present invention.

调制信号送出装置100中,在调制数据(以下,适当称为EFM信号) 插入的无调制区间相关的信息从追记关联信息410获得。 Modulated signal sending device 100, the modulated data (hereinafter, referred to as the EFM signal) is inserted into the non-modulated section 410 obtains information related to the associated write-once information. 在EFM数据的哪里插入无调制区间或插入几个无调制区间是任意的,未进行特定。 Where no insertion section EFM modulated data or insertion of several non-modulating interval is arbitrary, not be specific. 但是,它们可设定成可跟踪伺服已插入了无调制区间的光盘340, 即连续的无调制区间设定在跟踪伺il良的频带以下。 However, they may be set to be the tracking servo optical disk 340 has been inserted unmodulated section, i.e., a continuous unmodulated interval il good tracking servo set at a band less. 该跟踪的方法未 The tracking method is not

特别限定。 Particularly limited.

第3图的例中,在EFM调制前,将8比特的子编码部设为无调制区间,在调制后,将14信道比特的子编码部设为无调制区间。 Example 3 Fig., Prior to EFM modulation, eight bits of unmodulated subcode portion set interval, after modulation, the 14 channel bit sub-code portion of the non-modulating interval is set. 无调制区间可以设置在除同步图案外的子编码部及数据部的任意处。 No modulation section may be disposed at any except the sync pattern and the subcode data unit portion. 另外, 可以以某一定间隔或随机的间隔设置多个无调制区间。 Further, a plurality of non-modulating interval may be provided at a certain interval or at random intervals. 调制信息生成部12 0根据这样的追记关联信息410 ,生成在EFM数据图案的一部分设有无调制区间的EFM信号,输出到激光束记录器600。 Modulation information generating unit 120 according to information 410 associated with such writing, the generating section has a non-modulated portion of the EFM signal EFM data pattern, the laser beam is output to the recorder 600. 输出到激光束记录器600的EFM信号,即,光盘原盘320上记录的EFM信号的波形中,子编码部的信号电平成为O。 Is output to the laser beam recorder 600 EFM signal, i.e., the waveform of the EFM signal recorded on the optical disc master 320, the signal level of the sub coding portion becomes O. 这样制作的光盘340,在无调制区间的子编码部不存在凹坑。 Such optical disc 340 produced, there is no pit portion unmodulated subcode section. 即,都成为凸台区域。 I.e., the bosses have become area.

追记装置200中,取得追记关联信息410,预先存储到调制信息存储部210。 Writing apparatus 200 acquires related information recordable 410, modulation information previously stored in the storage unit 210. 追记控制部220对追记信息420执行BFM调制,控制发出高输出的激光的追记部230,在子编码部形成凹坑,以在相当于子编码部的区间记录该EFM信号。 The writing control unit 220 performs write-once BFM modulation information 420, the control unit emits a laser recordable high output 230, pits are formed in the sub-code portion, to the interval corresponding to the subcode portion recorded EFM signal. 第3图中斜线所表示的凹坑是由追记信息形成的凹坑。 Pits hatched in FIG. 3 are indicated by the write-once information formed pits. 由追记装置200执行追记后的光盘制品350,在相当于子编码部的区间记录追记信息420的调制信号。 200 performs the optical disc 350 after the writing article, the section corresponding to the sub recording write-once information encoding unit 420 by the writing means is a modulation signal.

第3图的例中,追记后的14信道比特的图案成为(01001000100100)。 The third embodiment in FIG, 14 after the letter postscript channel bit pattern is (01001000100100). 另外,在信道比特的l的位置中,EFM信号的电平反相。 Further, the position of the channel bit l of the EFM signal level is inverted phase. 该14信道比特是对40h的8比特的符号执行EFM调制而获得的。 The 14-bit channel bit symbol is 8 performs EFM modulation 40h is obtained. h表示16进制,8比特的图案为(01000000)。 h represents hexadecimal 16, a pattern of 8 bits (01000000). 该8比特用10进制表示则成为「64」的值。 The 8-bit 10 hexadecimal value becomes "64" in. 图中表示了通过3比特的容限比特而位于子编码部后的信息比特为OOh的示例。 FIG indicating an example of information bits after coding sub-unit located by margin bit of 3 bits is OOh.

这样,将信息数据的调制信号作为覆盖膜的凹坑的有无而记录的光盘上,可记录以同一调制方式调制的追记信息。 Thus, the modulated signal on the optical disc information data as the presence or absence of the cover film and the pit recorded, write-once information can be recorded in the same modulation scheme modulation. 通过在每个盘上记录不同的数据作为追记信息,可以作为光盘的识别信息来读取。 On each disc recorded by different data as write-once information, can be read as the identification information of the optical disc. 另外,执行追记后的光盘制品,在与传统的EFM调制对应的重放机中, 在重放信息数据的调制信号的同时可以重放追记信息的调制信号。 Further, after execution of the write-once optical disk products, with the conventional EFM modulation corresponding to the player, the reproduced modulated signal while information data modulated signal can be reproduced write-once information. 这样,可以不必在重放机中设置用以读出个别识别信息的特殊电路, Thus, a special circuit may not necessarily be provided for reading out the individual identification information in a reproduction machine,

就可以重i支个別识别信息。 I can support the weight of individual identification information.

上述说明中,在信息数据的EFM数据中插入无调制区间,但是也可以取代无调制区间而釆用执行了伺服专用的调制的伺服专用调制区间。 In the above description, no insert in the EFM modulated data information section data, but may be substituted without modulating interval and preclude the use of a dedicated servo performed modulated dedicated servo modulating interval. 该场合,追记关联信息410是指定在调制信号数据图案的任意区间中插入的执行了伺服专用调制后的调制区间的信息,调制信号送出装置100的调制信息生成部120根据追记关联信息,生成将调制信号数据图案的一部分作为伺服专用的伺服专用调制区间的调制信号数据,追记装置200的追记控制部220根据追记关联信息,执行向伺服专用调制区间追记上述追记信息的调制信号的控制。 In this case, the write-once-related information 410 is specified in an arbitrary interval modulation signal data pattern inserting execution information modulation section after servo-specific modulation, the modulated signal transmitted modulated information generation unit 100 of the 120 in accordance with write-once-related information, generates a portion of the modulated signal modulated data signal data pattern as a dedicated servo dedicated servo modulating interval, the writing means writing the control unit 200 controls the modulation signal 220 of the recordable write-once information specific to the servo-modulating interval related information in accordance with write-once performed. 另外,伺服专用调制区间的调制信号的强度设定在可读取由追记装置200执行追记后的已记录光盘的强度范围内。 Further, the intensity modulation signal modulated dedicated servo section is set can be read by the write-once recording apparatus 200 has executed the write-once disc within the intensity range.

接着,说明本发明的第2追记信息记录方法。 Next, a second recording method according to the present invention. 第2记录方法中, 在调制信号送出装置中生成对信息数据调制后的EFM信号,通过原盘制作工序及成形成膜工序制作记录了EFM信号的光盘,在追记装置中,参照调制信号送出装置生成的EFM数据,在任意的区间记录追记信息。 The second recording method, apparatus for generating information data signal EFM modulation, by mastering the forming step and the deposition step of producing the optical disc is recorded EFM signal sent in the modulated signal, the write-once device, the modulation reference signal sending means EFM data is generated, in any write-once information recording section.

第6图是说明本发明的第3追记信息记录方法的图。 FIG 6 is a view of a third recording method of the present invention.

调制信号送出装置100中,对重放的信息数据执行EFM调制,生成EFM数据图案,发送到追记装置200。 Modulated signal sending means 100, the reproduced information data performs an EFM modulation, EFM data pattern is generated, transmitted to the writing means 200. 追记装置200中,在调制信息存储部21 O预先存储该EFM数据图案。 Writing apparatus 200, the information storing section 21 O modulating the EFM data pattern stored in advance. 从调制信号送出装置10 0输出用与传统同样的处理生成的EFM信号,生成光盘原盘320。 Sent from the modulation signal means 100 similar to the output of the EFM signal generated by a conventional process, 320 generation optical disc master. 由该光盘原盘320制作的光盘340的凹坑相当于第6图的椭圆所表示的部分。 Portion of the optical disk 320 in the optical disc mastering pit 340 of FIG. 6 corresponds to an ellipse indicated. 追记装置200的追记控制部220中,参照调制信息存储部210中保存的EFM 数据执行追记,以在预定的区间发生错误。 Writing apparatus 200 writing control unit 220, referring to the data EFM modulated information stored in the storage unit 210 performs writing to an error occurs at a predetermined interval. 该区间是任意的,可以是连续的区间,也可以是根据规定的条件选择的区间。 The interval is arbitrary and may be continuous interval, the interval may be selected according to a predetermined condition.

第6图的例中,由于信息比特为r(n, EFM调制后的结果,形成4T=0、 3T=1、 4T=0、 6T-1的信息比特区间。在该信息比特区间内的4T-0 部分进行追记,设IT-O、 2T-1、 IT-O。即,与3T-1和6T-1分别对应的凹坑间的4T-0相当的凸台上,追记与斜线所示的2T-1相当的凹坑。 Example 6 FIG, since the information bits of r (n, after the EFM modulation result, a 4T = 0, 3T = 1, 4T = information bit interval 0, 6T-1 is. 4T in the information bits of segment -0 writing part, provided IT-O, 2T-1, IT-O. That is, 4T-0 with the corresponding boss, and between 3T-1 6T-1 respectively corresponding to the pit, and oblique lines recordable illustrated 2T-1 corresponding to the pits.
