【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明は、書換え形光ディスクのデータ記録方法に係り、より詳しくは、記録領域に欠陥セクタを生じた場合の交替処理方法に関する。 The present invention relates to relates to a data recording method for rewritable optical discs, and more particularly, to a replacement processing method in a case which caused the defective sector in the recording area.

【0002】 [0002]

【従来の技術】一般に、書換型又は追記型の光ディスクは、ミクロンオーダーもしくはサブミクロンオーダーの微細なプリフォーマットパターンが形成された基板の当該プリフォーマットパターン形成面上に、ナノメータオーダーの薄膜を1層又は多層に積層してなるので、全記録領域を欠陥なく形成することは極めて困難であり、一部に欠陥を含む場合の方がむしろ普通である。 In general, rewritable or write-once optical disc, micron-order or on the preformat pattern forming surface of the fine substrate preformat pattern is formed submicron, one layer of thin film of nanometer order or so formed by laminating the multilayer, and it is extremely difficult to form the entire recording area without defects, it is rather common person when part having defects. このため、書換型の光ディスクにおいては、使用開始前に記録領域のサーティファイを行ない、データ記録を正常に行なえない領域(欠陥セクタ)を予め調べ、欠陥セクタに対するデータ記録を禁止する処理を施してから使用するようにしている。 Therefore, in the rewritable optical disc, it performs certification of the recording area before starting use, examines the areas without performing the data normally recorded (defective sectors) in advance, after subjected to a process of prohibiting the data recording for the defective sector It is to use. また、記録領域のサーティファイが不可能な追記型の光ディスクにおいては、データ記録時に、データ信号と共に誤り訂正用のコード(ECC; E In the optical disk certification is a write-once impossible recording area, data recording, the error correction code with the data signal (ECC; E
rror Correcting Code)を記録し、ある程度記録データに誤りがあっても正しいデータを読みだせるようにしている。 rror Correcting Code) is recorded, and can be read the correct data even if there is an error in some degree record data.

【0003】しかし、かかる欠陥セクタ対策を行なったとしても、記録膜の劣化等によって欠陥セクタが事後的に発生したり、あるいは欠陥の程度が経時的に悪化したりすることがあるので、これだけでは欠陥セクタ対策として不充分である。 However, even if subjected to such a defective sector measures, since defective sector due to deterioration of the recording film may be or ex post occurs, or the degree of defects or over time deteriorates, this alone it is insufficient as a defect sector measures. 従来より、使用中に発生する欠陥セクタに対処するため、欠陥セクタに記録しようとしたデータを他のセクタ(交替セクタ)に書き替える交替処理が、光ディスクのデータ記録方法として採用されている。 Conventionally, to deal with defective sectors generated during use, replacing process for rewriting the data to be recorded in the defective sector to another sector (replacement sector) have been adopted as a data recording method for an optical disc. 従来より知られている交替処理方法には、欠陥セクタの次セクタにデータを交替処理する方法、データ記録領域とは別に設けられた交替処理専用の領域に欠陥セクタのデータを交替処理する方法、同時に複数セクタずつデータを記録してゆき、記録した複数セクタ中に欠陥セクタを含む場合、同時に記録された複数セクタの次セクタに欠陥セクタのデータを交替処理する方法などがある。 The replacement processing method conventionally known, a method of replacing process the data in the next sector of the defective sector, a method of replacing process the data of the defective sector in the region of the replacement process only provided separately from the data recording area, Yuki simultaneously recording data by a plurality of sectors, when including a defective sector during recording the plurality of sectors, and a method of replacing process the data of the defective sector in the following sectors of the plurality of sectors which are recorded simultaneously.

【0004】前記の方法は、ヘッド装置を光ディスクの半径方向に移動することなくデータの読みだしを行なうことができるので、データの読みだしを高速に行なうことができるという利点を有するが、その反面、複数セクタを書き込んでいるときに書き込みセクタの途中で欠陥セクタが検出されると、次セクタ以降のデータをずらして書き込み直さなくてはならないので、データの書き込みに時間がかかるという欠点がある。 [0004] The methods can be performed to read the data without moving the head unit in a radial direction of the optical disk, it has the advantage that the read data can be performed at high speed, on the other hand when middle defective sector write sector is detected while writing multiple sectors, since must re writing by shifting the data of the subsequent sector, there is a disadvantage that the time for writing data is applied. 前記の方法は、データの書き込み領域と交替セクタとが異なる領域に分離されているので、欠陥セクタのデータのみを交替セクタに書き直せば良く、前記のようにデータの書き込みに時間がかかるという欠点はないが、その反面、ヘッド装置を光ディスクの半径方向に移動しなくては交替セクタの読みだしができないので、データの読みだしに時間がかかるという欠点がある。 The method, the write area of ​​the data and the replacement sector are separated into different regions, may be rewritten only data of the defective sector replacement sector, the disadvantage that it takes time to write data, as no, but on the other hand, have to move the head device in the radial direction of the optical disc can not have read the replacement sector, there is a disadvantage that the time to read data such. 前記の方法は、その中間的な特徴を有する。 The method has its intermediate characteristics.

【0005】ところで、書換型光ディスクの使用態様として、書換型光ディスクをあたかも追記型光ディスクのように使用する仮想追記型光ディスクと呼称されるものがある。 Meanwhile, as a mode of use of the rewritable optical disk, there is what is called a virtual write-once optical disc be used as if it were a write-once optical disc the rewritable optical disc. これは、例えばアプリケーション・プログラムやデータベースなどのデータを書換型光ディスクにシーケンシャルに記録し、かつ一旦データを記録した後はデータの書換えを行なわないといった使用方法であって、 This example records data such as application programs and databases sequentially to a rewritable optical disc, and once after recording data is a method using such does not perform rewriting of data,
少数枚の読みだし専用の光ディスクを迅速に作製したい場合に用いられる。 It is used when you want to quickly create a dedicated optical disk read of the small number of sheets.

【0006】 [0006]

【発明が解決しようとする課題】書換型光ディスクは、 Rewritable optical disc The object of the invention is to solve the above-
繰返しデータの消去と再書き込みとを行なうことができるから、一般的には、前記又はの交替処理方式がとられる。 Since it is possible to perform a re-writing and erasing of the repeating data, in general, the or replacement processing method is adopted. ところが、仮想追記型光ディスクとして用いる場合には、記録するデータの種類によって、ある程度書き込み速度を犠牲にしてもデータの読みだしを高速に行ないたい場合(前記の交替処理方法を採用することで達成できる)、あるいは書き込み速度をそれほど低下することなくデータの読みだしもある程度高速に行ないたい場合(前記の交替処理方法を採用することで達成できる)のみならず、ある程度データの読みだし速度を犠牲にしても書き込み速度を高速に行ないたい場合(前記の交替処理方法を採用することで達成できる)もある。 However, when used as a virtual write-once optical disk, the type of data to be recorded, can be achieved by adopting a replacement process method when (the you want to do the high speed reading even data at the expense of somewhat writing speed ), or not if you also want perform somewhat high-speed reading of data without reducing the writing speed so only (can be achieved by adopting the replacement processing method), at the expense of speed out somewhat reading data even if you want to do the writing speed to high speed (it can be achieved by adopting the replacement processing method) also.

【0007】しかるに、従来の光ディスクドライブ装置には、1種類の交替処理方法しか備えられていないため、記録するデータの種類によって最適な交替処理方法を選択するといった使用方法をとることができない、といった不便がある。 [0007] However, the conventional optical disc drive apparatus, because it is not provided with only one type of replacement processing method, it is impossible to employ a method using such selecting an optimal replacement processing method according to the type of data to be recorded, such as there is an inconvenience.

【0008】本発明は、かかる従来技術の不都合を解消するためになされたものであって、その目的は、記録するデータの種類によって最適なデータ書き込み速度又は読みだし速度を得られる書換型光ディスクのデータ記録方法を提供するにある。 [0008] The present invention was made to solve the disadvantages of the prior art, its object is a rewritable optical disk for optimal data writing speed or readout rate according to the type of data to be recorded to provide a data recording method.

【0009】 [0009]

【課題を解決するための手段】本発明は、前記の目的を達成するため、光ディスク又は光ディスクを回転可能に収納するディスクカートリッジに付設されたICメモリ若しくは光ディスクのドライブ装置に付設されたICメモリに、複数の交替処理方法を実行する複数のプログラムを備えておき、ユーザがそれらのうちから適宜の交替処理方法を選択できるようにした。 The present invention SUMMARY OF] In order to achieve the above object, an optical disc or optical disc in the IC memory annexed to rotatably drive the IC memory or optical disk, which is attached to a disk cartridge for housing , previously provided with a plurality of programs for executing a plurality of replacement processing method, the user is allowed to select a suitable replacement processing method from among them.

【0010】 [0010]

【作用】仮想追記型光ディスクは、書換型光ディスクを用いて作製されるから、データの書換えを伴う交替処理方法及びデータの書換えを伴わない交替処理方法のいずれをも採用可能である。 [Action] virtual write-once optical disc, since manufactured using a rewritable optical disc, it is also possible to employ any of the replacement processing method that does not involve rewriting replacement processing method and data involving the rewriting of data. そこで、光ディスク又は光ディスクを回転可能に収納するディスクカートリッジに付設されたICメモリ若しくは光ディスクのドライブ装置に付設されたICメモリ等に複数の交替処理方法を実行する複数のプログラムを備えておくことによって、ユーザに適宜の交替処理方法を選択させることができる。 Therefore, by keeping a plurality of programs for executing a plurality of replacement processing method in an IC memory or the like which is attached to the drive unit of the IC memory or optical disk, which is attached to the disc cartridge for rotatably accommodating the optical disc or optical disc, it can be selected an appropriate replacement processing method to the user. したがって、光ディスク等に書き込み速度優先の交替処理方法を実行するプログラムと読みだし速度優先の交替処理方法を実行するプログラムを備えておけば、必要に応じて書き込み速度の早いデータ記録又は読みだし速度の早いデータ記録を実現でき、仮想追記型光ディスクの使い勝手を格段に良くできる。 Therefore, if provided with a program for executing replacement processing method Programs readout speed priority for executing replacement processing method for writing speed priority on an optical disk or the like, fast data recording or readout speed of writing speed as needed can achieve fast data recording, it can significantly improve the usability of the virtual write-once optical disc.

例を示す説明図である。 Example is an explanatory view showing the.

【0012】まず、本例における交替処理の手順を、図1にしたがって説明する。 [0012] First, the procedure of the replacement process in the present embodiment will be described with reference to FIG. 交替処理が開始されると、ステップS−1で交替処理方法の選択が行なわれる。 When replacement process is started, the selection of replacement processing method is performed in step S-1. なお、欠陥セクタの検出は、光ディスクにデータの書き込みを行ない、書き込み直後に当該記録データの読みだしを行ない、これら書き込みデータと読みだしデータとの比較を行なって、正しいデータが読み出せないと判断された場合に開始される。 The detection of defective sectors, performs the writing of data to the optical disk, performs a read of the recording data immediately after writing, determines that performs a comparison between the read and these written data data can not be read out correct data It is initiated when it is. この方法は、書換型又は追記型の光ディスクで行なわれている通常の欠陥セクタ検出方法である。 This method is usually defective sector detection method is performed in a rewritable or write-once optical disc. 交替処理方法の選択は、前記したように交替処理方法によってデータの書き込み速度や読みだし速度に差があることを考慮し、ユーザが記録しようとするデータの種類に応じて適宜選択する。 Selection of the alternate treatment method, considering replacement process that method there is a difference in the reading speed and writing speed of the data by as described above, the user appropriately selected depending on the type of data to be recorded.

【0013】例えば、ステップS−2の交替処理方法1 [0013] For example, replacement processing method 1 in step S-2
として前記の方法(欠陥セクタの次セクタにデータを交替処理する方法)が備えられ、交替処理方法2として前記の方法(データ記録領域とは別に設けられた交替処理専用の領域に欠陥セクタのデータを交替処理する方法)が備えられ、交替処理方法3として前記の方法(同時に複数セクタずつデータを記録してゆき、記録した複数セクタ中に欠陥セクタを含む場合、同時に記録された複数セクタの次セクタに欠陥セクタのデータを交替処理する方法)が備えられている場合において、データの書き込み速度をある程度犠牲にしても高速でデータの読みだしを行ないたいという場合には、前記の方法が選択される。 The method (a method of replacing process the data in the next sector of the defect sector) is provided, the data of the above methods (data recording area and defective sectors provided separately from alternation processing dedicated area as a replacement processing method 2 as provided with a method for replacing process), following the methods (Yuki simultaneously recording data by a plurality of sectors, when including a defective sector during recording the plurality of sectors, a plurality of sectors which are recorded simultaneously as a replacement processing method 3 in the case where a method of replacing process the data of the defective sector to sector) is provided, in the case that even if a certain sacrifice of the data write speed want to do read data at high speed, the method is selected that. 逆に、データの読みだし速度をある程度犠牲にしても高速でデータの書き込みを行ないたいという場合には、前記の方法が選択される。 Conversely, if that be a certain sacrifice of speed reading of data want to perform writing of data at high speed, the method is selected. さらに、データの書き込み速度をあまり犠牲にすることなくデータの読みだしもある程度高速に行ないたいという場合には、前記の方法が選択される。 In addition, in the case that want to be carried out to some extent the high-speed reading of data without sacrificing too much of the writing speed of the data, the method is selected.

【0014】ステップS−2では、選択された交替処理方法にしたがって、欠陥セクタの交替処理が行なわれる。 [0014] At step S-2, according to replacement processing method is selected, replacement processing of a defective sector is performed. この交替処理方法を実行するプログラムは、ドライブ装置内に備えられたメモリに格納しておくこともできるし、データを記録しようとする光ディスクに記録しておくこともできる。 The program that executes the replacement process method can either be stored in memory provided in the drive apparatus, it may be recorded on the optical disk to be recorded the data.

【0015】次いでステップS−3にいって、欠陥セクタに記録しようとしたデータが交替セクタに書き込まれ、ステップS−4で、当該交替セクタに書き込まれたデータの読みだしが行なわれ、ステップS−5で、交替セクタに正しいデータが書き込まれたか否かの判断が行なわれる。 [0015] then go to step S-3, the data to be recorded in the defective sector is written in the replacement sector, at step S-4, read the data written in the replacement sector is performed, step S -5, determining whether or not correct data replacement sector is written is performed.

【0016】ステップS−5で、交替セクタに正しいデータが書き込まれたと判断された場合には、光ディスク上のセクタの配列(物理アドレス)と実際のデータの書き込み順序(論理アドレス)とが異なることになるので、ステップS−6で、光ディスクの管理領域に記録された論理アドレスを変更して、書き込み順にデータが読みだせるように処理した上で、動作を終了する。 [0016] In step S-5, if the correct data in the replacement sector is determined to have been written, the write sequence (logical address) of the actual data with the sequence of sectors on the optical disc (physical address) are different since, in step S-6, by changing the logical address recorded in the management area of ​​the optical disc, on which data writing order is treated as read out, the operation ends. ステップS−5で、交替セクタに正しいデータが書き込めなかったと判断された場合には、そのまま動作を終了する。 In Step S-5, if the correct data in the replacement sector is determined to not be written is directly ends the operation.
正しいデータの書き込みは、同一光ディスク内の別領域にデータを書き直すか、あるいは光ディスクを交換することによって行なわれる。 The correct data write or rewrite the data in a different area of ​​the same optical in the disk, or carried out by replacing the optical disc.

【0017】次に、前記,,の交替処理方法を図3〜図5に基づいて説明すると共に、各交替処理方法を実行した後に行なわれるアドレス管理表の論理アドレスの変更方法について説明する。 Next, while described with reference to FIGS replacement processing method of the ,, will be described how to change the logical address of the address management table which is performed after performing the respective replacement processing method.

【0018】図3は、前記の交替処理方法の説明図であって、0トラック−0セクタから以降がユーザ領域1 [0018] FIG. 3 is an explanatory view of the replacement processing method, track 0 -0 later from sector user area 1
になっており、0トラック−0セクタからアドレス番号の若い順にデータが書き込まれている。 Has become, 0 data from the track -0 sector in ascending order of address number is written. 10トラック− 10 tracks -
5セクタに欠陥セクタ3を生じた場合、その次セクタすなわち10トラック−6セクタが交替セクタ4となって、10トラック−5セクタに記録しようとしたデータが書き込まれる。 If resulted defective sector 3 to 5 sectors, the next sector i.e. 10 tracks -6 sectors become replacement sector 4, data to be recorded on 10 tracks -5 sector is written. このとき、アドレス管理表には、図2 In this case, the address management table, FIG. 2
(A)に示すように、欠陥セクタ3の物理アドレス(1 (A), the physical address of the defective sector 3 (1
0トラック−5セクタ)と交替セクタ4の物理アドレス(10トラック−6セクタ)、それに交替セクタ4の論理アドレス(506)が書き込まれ、光ディスクに対するデータの書き込み順序及び読みだし順序が管理される。 0 Track -5 sector) and the physical address of the replacement sector 4 (10 tracks -6 sectors), it logical address of the replacement sector 4 (506) is written in the order read write sequence and data on the optical disk is managed. かように論理アドレスは光ディスクに対する実際のデータ書き込み順序を表すから、10トラック−7セクタ以降の各セクタについては、物理アドレスから算出される0トラック−0セクタからのセクタ数よりも論理アドレスが1つづつ少なくなる。 Because Such logical address represents the actual data write ordering with respect to the optical disc, for each sector of the 10 tracks -7 sectors later, the sector logical address than the number from 0 track -0 sector calculated from the physical address 1 by one less. したがって、11トラック−5セクタに再度欠陥セクタを生じ、11トラック− Thus, resulting again defective sector 11 tracks -5 sector, 11 track -
6セクタに交替セクタが設けられたとき、2番目の交替セクタの論理アドレスは図2(B)に示すように、(5 When replacement sector 6 sector is provided, the logical address of the second replacement sector as shown in FIG. 2 (B), (5
55)となる。 The 55).

【0019】図4は、前記の交替処理方法の説明図であって、0トラック−0セクタから19999トラック−49セクタまでがユーザ領域1になっており、200 [0019] FIG. 4 is an explanatory view of the replacement processing method, the track 0 -0 sector to 19999 tracks -49 sector has become a user area 1, 200
00トラック−0セクタから20002トラック−49 From track 00 -0 sector 20002 truck -49
セクタまでが交替領域2になっている。 Until the sector is in the spare area 2. そして、0トラック−0セクタからアドレス番号の若い順にデータが書き込まれ、1010トラック−5セクタに至って欠陥セクタ3を生じた場合、交替領域2の最初のセクタすなわち20000トラック−0セクタに欠陥セクタ3のデータが書き込まれる。 Then, track 0 -0 data is written from the sector in ascending order of address numbers, 1010 tracks -5 case any defective sector 3 led to the sector, the defective sector 3 in the first sector ie 20000 tracks -0 sector of spare area 2 data is written. このとき、アドレス管理表には、図2(C)に示すように、欠陥セクタ3の物理アドレス(1010トラック−5セクタ)と交替セクタ4の物理アドレス(20000トラック−0セクタ)、それに交替セクタ4の論理アドレス(50504)が書き込まれ、光ディスクに対するデータの書き込み順序及び読みだし順序が管理される。 In this case, the address management table, as shown in FIG. 2 (C), the physical address of the defective sector 3 (1010 tracks -5 sector) and the physical address of the replacement sector 4 (20000 tracks -0 sector), replacement sector it 4 of the logical address (50504) is written, the sequence read write sequence and data on the optical disk is managed. 交替処理されたデータ以後のデータは、1010トラック−6セクタからアドレス番号が若い順に書き込まれる。 Data of the replacement processed data after the 1010 track -6 address number from the sector are written in ascending order. この場合には、交替領域2がユーザ領域1とは別に設けられているので、1010トラック−6セクタ以降の各セクタについては、物理アドレスから算出されるセクタ数の増加に応じて論理アドレスが1つづつ増加する。 In this case, since the replacement area 2 is provided separately from the user area 1, for each sector of 1010 tracks -6 sector later, a logical address according to an increase in the number of sectors is calculated from the physical address 1 by one to increase. したがって、1011トラック−5セクタに再度欠陥セクタを生じた場合、20000 Therefore, when produced again defective sector 1011 tracks -5 sector, 20000
トラック−1セクタに交替セクタが設けられ、その交替セクタの論理アドレスは、図2(D)に示すように、 Replacement sector is provided in the track -1 sector, logical address of the alternate sector is, as shown in FIG. 2 (D),
(50554)となる。 To become (50,554).

【0020】図5は、前記の交替処理方法の説明図であって、0トラック−0セクタからアドレス番号の若い順に2010トラック−7セクタまでデータが書き込まれた段階で、2010トラック−5セクタが欠陥セクタ3であることが検出された場合、書き込み済みのセクタの次セクタすなわち2010トラック−8セクタに欠陥セクタ3のデータが書き込まれる。 [0020] FIG. 5 is an explanatory view of the replacement processing method, at 0 stage data from the track -0 sector until 2010 tracks -7 sectors in ascending order of address number is written, 2010 track -5 sector If it is defective sector 3 is detected, the data of the defective sector 3 is written in the next sector ie 2010 tracks -8 sector of written sectors. このとき、アドレス管理表には、図2(E)に示すように、欠陥セクタ3の物理アドレス(2010トラック−5セクタ)と交替セクタ4の物理アドレス(2010トラック−8セクタ)、それに交替セクタ4の論理アドレス(10050 In this case, the address management table, as shown in FIG. 2 (E), the physical address of the defective sector 3 (2010 tracks -5 sector) and the physical address of the replacement sector 4 (2010 track -8 sectors), replacement sector it 4 of the logical address (10050
4)が書き込まれ、光ディスクに対するデータの書き込み順序及び読みだし順序が管理される。 4) is written, the sequence read write sequence and data on the optical disk is managed. 交替処理されたデータ以後のデータは、2010トラック−9セクタからアドレス番号が若い順に書き込まれる。 Data of the replacement processed data after the address 2010 track -9 sector number is written in ascending order. この場合には、前記の交替処理方法を選択した場合と同様に、2 In this case, as in the case of selecting the replacement processing method, 2
010トラック−9セクタ以降の各セクタについては、 For each sector of the 010 track -9 sector and later,
物理アドレスから算出される0トラック−0セクタからのセクタ数よりも論理アドレスが1つづつ少なくなる。 Sector logical address than the number from 0 track -0 sector calculated from the physical address is one at least.
したがって、2011トラック−5セクタに再度欠陥セクタを生じ、2011トラック−8セクタに交替セクタが設けられたとき、2番目の交替セクタの論理アドレスは、図2(F)に示すように、(100553)となる。 Thus, resulting again defective sector 2011 tracks -5 sector, when the replacement sector is provided in the 2011 track -8 sector, the logical address of the second replacement sector, as shown in FIG. 2 (F), (100553 ) and a.

【0021】前記した交替処理方法を実行するプログラムは、光ディスク自体に記憶しておくこともできるし、 The program for executing replacement processing method above, can either be stored on the optical disk itself,
