Field of the Invention The present invention relates to a method of recording disc information in a recordable optical disc, and more particularly, to a method of recording speed information and write strategy information by speed in the disc information.

광 기록매체로서 대용량의 데이터를 기록할 수 있는 광 디스크가 널리 사용되고 있다. 그 중에서도 최근에는 고화질의 비디오 데이터와 고음질의 오디오 데이터를 장시간 동안 기록하여 저장할 수 있는 새로운 고밀도 광기록 매체(HD-DVD), 예를 들어 블루레이 디스크(Blu-ray Disc)가 개발되고 있다. As optical recording media, optical disks capable of recording large amounts of data are widely used. Recently, new high-density optical recording media (HD-DVD), for example, Blu-ray Disc, which can record and store high-quality video data and high-quality audio data for a long time, have been developed.

Blu-ray Disc, the next-generation HD-DVD technology, is a next-generation optical recording solution that can store data that significantly surpasses existing DVDs. Recently, world-standard technical specifications have been established.

차세대 HD-DVD 세계 표준중의 하나인 블루레이 디스크는 650nm 파장의 적색 레이저를 사용하는 현재의 DVD 보다 훨씬 조밀한 405nm의 청자색 레이저를 사용하며, 0.1mm의 광투과층을 가진 두께 1.2mm, 직경 12cm의 디스크에 현재의 DVD 보다 월등한 양의 데이터를 저장할 수 있다. Blu-ray Disc, one of the world's next-generation HD-DVD world standards, uses a 405nm blue-violet laser, which is much denser than current DVDs that use 650nm red lasers, and has a thickness of 1.2mm and a diameter of 0.1mm.

For convenience of explanation, an optical disc will be described by taking a case of a recordable Blu-ray disc (BD-RE / BD-WO) as an example.

아울러, 본발명에서 사용되는 용어는 가능한한 현재 널리 사용되는 일반적인 용어를 선택하였으나, 특정한 경우는 출원인이 임의로 선정한 용어도 있으며 이경우는 해당되는 발명의 설명부분에서 상세히 그 의미를 기재하였으므로, 단순한 용어의 명칭이 아닌 용어가 가지는 의미로서 본발명을 파악하여야 됨을 밝혀두고자 한다.In addition, the terms used in the present invention was selected as a general term widely used as possible now, but in certain cases, the term is arbitrarily selected by the applicant, in which case the meaning is described in detail in the description of the invention, The present invention is to be understood as the meaning of terms rather than names.

특히, 본발명은 기록관련정보(WS)를 디스크정보내에 기록하는 방법에 있어 복수의 기록관련정보(WS)를 규격화하여 결정해두고, 복수의 기록관련정보(WS) 종류중 어느하나를 디스크제작시 선택적으로 기록해두고, 기록재생장치(도9)는 디스크정보에 기록된 기록관련정보(WS)를 참조하여 기록재생을 수행하는 것을 특징으로 하는 바, 이하 본발명의 정확한 이해를 위해 본발명에서 사용된 "기록관련정보 (WS)"의 의미를 상세히 설명하고자 한다.In particular, in the present invention, in the method of recording the recording related information WS in the disc information, the plurality of recording related information WS are standardized and determined, and any one of the plurality of types of recording related information WS is produced. In the present invention, the recording and reproducing apparatus (FIG. 9) performs recording and reproducing with reference to the recording related information WS recorded in the disc information. The meaning of "record related information (WS)" used will be explained in detail.

일반적으로 기록가능한 광디스크는 광디스크내의 기록층에 픽업(도9, 11)을 통해 레이저빔을 주사하여 기록층의 매질특성을 변경시키므로서 기록을 수행하게 된다. 따라서, 레이저빔의 강도(기록파워)를 어느정도로 할 것인지, 기록파워를 주사하는 시간을 어느정도로 할 것인지등을 결정하여야 하며, 상기와같이 결정된 다양한 기록관련 정보를 일반적으로 "Write Strategy(WS)"로 명명하고, 특정 "Write Strategy(WS)"내에 기록되는 구체적인 내용을 "Write Strategy(WS) 파라미터(parameters)"라 명명하기도 한다. 따라서, 본발명에서 사용된 기록관련정보(WS)는 이러한 의미를 통칭하여 사용한 것이다. In general, a recordable optical disc performs recording by scanning a laser beam through a pickup (FIGS. 9 and 11) to a recording layer in the optical disc to change the characteristics of the recording layer. Therefore, it is necessary to determine how much the intensity (recording power) of the laser beam, how long to scan the recording power, and the like. The various recording-related information determined as described above is generally referred to as "Write Strategy (WS)". "Write Strategy (WS) parameters" may also be referred to as "Write Strategy (WS) parameters." Therefore, the record related information WS used in the present invention is used collectively for this meaning.

또한 기록관련정보(WS)는 다양한 방식으로 기록가능한 바, 디스크가 고밀도/고배속화 될수록 기록층의 매질특성뿐만아니라 기록배속(달리 표현하면 디스크회전 수)등에 큰영향을 받게되므로 더욱 정밀한 방식이 요구된다 할것이다. In addition, the recording related information (WS) can be recorded in various ways. As the density of the disk becomes higher and higher, the more precise method is required because the recording layer speed (in other words, the number of rotations of the disk) is greatly affected as well as the characteristics of the recording layer. Will be.

상기 다양한 기록관련정보(WS)는 예를들면, 다음과 같은 종류가 있을 수 있다. 하나는 기록층매질에 형성하는 기록마크 (mark) 크기(n)보다 하나적은 기록펄스(pulse)를 가지는 방식이 있고 (이를 "(n-1) Write Strategy"라고도 한다), 또는 기록마크(mark) 크기(n)보다 절반의 기록펄스(pulse)를 가지는 방식이 있을 수 있다(이를 "n/2 Write Strategy"라고도 한다). 상기외에도 새로운 기록관련정보(WS)가 계속 개발되고 있는 실정이며, 서로다른 종류의 기록관련정보(WS)는 기록관련정보(WS)에 적용하는 파라미터(parameter)들도 모두 상이해 짐에 따라 상기와 같이 여러가지 방식의 기록관련정보(WS)가 존재하는 경우에, 디스크제작자는 각각의 기록관련정보(WS)를 모두 적용하여 테스트하고 그결과를 디스크정보에 기록해두어야 하므로 많은 시간을 투자하여야 하고 이는 디스크의 제조단가를 상승시키는 원인이 되기도 한다. 따라서 본발명은 기록관련정보(WS)를 디스크정보내에 효율적으로 기록하는 방법을 제시하고자 하는 것이다.The various record related information WS may be of the following types, for example. One method has a recording pulse smaller than the recording mark size (n) formed in the recording layer medium (also referred to as "(n-1) Write Strategy"), or recording mark ) There may be a method having a recording pulse of half the size (n) (also called "n / 2 write strategy"). In addition to the above, new record-related information WS is continuously being developed, and different types of record-related information WS are different as parameters applied to the record-related information WS are also different. When there are various types of recording related information (WS) as shown in the drawing, the disc maker has to invest a lot of time because all the recording related information (WS) is applied and tested, and the result is recorded in the disk information. It may also cause an increase in the manufacturing cost of the disc. Accordingly, the present invention intends to suggest a method for efficiently recording the recording related information WS in the disc information.

도1은 본발명에 의한 광디스크의 구조를 도시한 것으로, 본발명이 적용되는 광디스크는 기록가능한 광디스크이면 충분하고, 여러번 재기록가능한 광디스크이거나 1회기록가능한 광디스크인 것을 불문하고 적용가능하다 할 것이다.Fig. 1 shows the structure of an optical disc according to the present invention, and an optical disc to which the present invention is applied is sufficient if a recordable optical disc is sufficient, and it can be applied regardless of whether it is an optical disc that can be rewritable many times or once.

도1은 본발명의 광디스크의 구조로서 기록층이 하나인 싱글레이어(Single Layer) 구조에 대해 도시되어 있으며, 도2는 기록층이 복수인 듀얼레이어(Dual Layer)의 경우에 대해 도시한 것이다. 듀얼레이어에서 리드인으로 시작되는 기록층을 제1기록층(Layer0)이라 하고, 리드아웃으로 끝나는 기록층을 제2기록층(Layer1) 이라 한다. 또한 기록층은 확장가능하며 이경우 제3기록층(Layer2), 제4기록층 (Layer3)과 같이 명명하면 될 것이다. FIG. 1 is a structure of an optical disc of the present invention, which shows a single layer structure having one recording layer, and FIG. 2 shows a case of a dual layer having multiple recording layers. The recording layer starting with lead-in in the dual layer is called the first recording layer (Layer0), and the recording layer ending with lead-out is called the second recording layer (Layer1). The recording layer is also expandable, and in this case, the third recording layer (Layer2) and the fourth recording layer (Layer3) may be named.

도1,도2에서, 본발명의 광디스크는 디스크의 내주와 외주영역에는 관리영역으로 리드인과 리드아웃영역이 구비되어 있고, 특히 디스크내주영역에는 프리기록 (pre-recorded)된 영역과 기록가능한(rewritable or write-once) 영역으로 구분되어 있다. 프리기록된 영역이란 디스크제작시 이미 기록되어 있는 영역으로 사용자 또는 시스템에 의해 더이상 기록이 불가능한 영역으로, 특히, BD-RE/WO 에서는 상기 프리기록영역을 PIC(Permanent Information & Control data) 라고 명명하며, 상기 PIC영역에는 디스크의 기록등에 필요한 정보로서, 디스크정보(Disc Information, 이하 'DI'라고도 한다)가 기록되어 있다. 데이터영역 (Data Area)에는 사용자의 실제데이터가 기록되는 유저데이터영역(User Data Area)와 결함영역의 발생시 이를 대체하기 위한 스페어영역 (ISA, OSA)이 각각 구비되어 있으며, 특히 BD-WO와 같은 1회 기록가능한 광디스크에서는 디스크 결함관리 및 일반관리를 위한 정보를 기록하는 TDMA (Temporary Defect Management Area)가 구비되어 있다. 재기록가능한 BD-RE의 경우 TDMA는 필요없는 영역이므로 reserved영역으로 남겨두게 된다.1 and 2, the optical disc of the present invention includes a lead-in and a lead-out area as a management area in the inner and outer areas of the disc, and in particular, a pre-recorded area and a recordable area in the inner disc area. It is divided into (rewritable or write-once) areas. The pre-recorded area is an area that is already recorded at the time of disc creation and is no longer recordable by the user or the system. In particular, in BD-RE / WO, the pre-recorded area is called PIC (Permanent Information & Control data). In the PIC area, disc information (hereinafter also referred to as "DI") is recorded as information necessary for recording a disc. The data area is provided with a user data area in which the user's actual data is recorded and spare areas (ISA, OSA) for replacing a defective area, in particular, such as a BD-WO. An optical disc that can be written once is provided with a TDMA (Temporary Defect Management Area) for recording information for disc defect management and general management. In the case of a rewritable BD-RE, TDMA is left as a reserved area because it is not necessary.

본발명은 상기 프리기록된 영역에 디스크정보로서 디스크의 기록재생에 필요한 배속정보 및 기록관련정보(WS)를 효율적으로 기록하는 방법에 관한 것이다. 규격화된 디스크의 종류마다 프리기록된 영역에의 기록방식이 상이하게 적용됨은 당연하다 할 것이며, BD-RE/WO의 경우 상기 프리기록된 영역으로서 PIC영역은 바이페 이즈(Biphase)된 고주파변조된 신호로 기록해두고 있으며, 해당영역의 고주파변조된 신호를 특정의 재생방식에 따라 재생하고 이로부터 정보를 취득하게된다. The present invention relates to a method of efficiently recording double speed information and recording related information (WS) required for recording and reproducing a disc as disc information in the pre-recorded area. Naturally, the recording method in the pre-recorded area is applied differently to each type of standardized disc. In the case of BD-RE / WO, the PIC area as the pre-recorded area is a biphasic high-frequency modulated type. Recorded as a signal, the high frequency modulated signal of the corresponding area is reproduced according to a specific reproduction method and information is obtained from the same.

도3은 도1,도2와 같은 디스크구조에서 PIC영역의 구조를 간략히 도시한 것이다. 이는 앞서 설명한 바와 같이 고주파변조된 PIC영역내의 정보를 모두 취득하였을때 도3과 같은 구조로 정보를 재배열할 수 있음을 의미하는 것으로, 물리적으로 PIC영역이 도2와 같이 기록되어 있는 것은 아니라 할것이다. BD-RE/WO에서의 최소기록단위는 '1클러스터(cluster)'로 나타내고 PIC영역은 544클러스터가 모여 하나의 상위 기록단위로서 프레그먼트(Fragment)를 형성하고, 총5개의 프레그먼트 (Fragment)가 모여 PIC영역을 형성하게 된다. 첫번째 프레그먼트(IF0)의 선두 클러스터에는 디스크정보를 기록하게 되는 바, 디스크정보는 해당 광디스크가 허용가능한 기록층 및 배속별로 복수의 개수로 기록하며, 하나의 디스크정보는 112bytes로 구성하였다. 112bytes로 구성된 디스크정보를 특히 디스크정보 프레임 (DI frame)이라고도 한다. 또한, 나머지 프레그먼트의 선두 클러스터에도 동일한 내용의 디스크정보를 반복하여 기록하여 둠으로서, 디스크정보의 손실에 대응할 수 있게 하였다. FIG. 3 briefly shows the structure of the PIC region in the disk structure shown in FIGS. This means that when all the information in the high frequency modulated PIC region is acquired as described above, the information can be rearranged in the structure as shown in FIG. 3, and the PIC region is not physically recorded as shown in FIG. 2. . In the BD-RE / WO, the minimum recording unit is represented by 'cluster', and the PIC area consists of 544 clusters to form a fragment as one upper recording unit, and a total of five fragments ( Fragments) gather to form the PIC region. Disc information is recorded in the head cluster of the first fragment IF0. The disc information is recorded in plural numbers for each recording layer and double speed allowable for the optical disc, and one disc information is composed of 112 bytes. The disk information composed of 112 bytes is also called a disk information frame (DI frame). In addition, by repeatedly recording the disk information having the same contents in the head cluster of the remaining fragments, it is possible to cope with the loss of the disk information.

각각의 디스크정보내에는 해당 기록층 및 배속을 표시하는 정보와 상기 기록층 및 배속에 대응하는 기록관련정보(WS)가 기록되어 있어, 해당 광디스크의 기록재생에 이러한 정보들를 활용하도록 함으로서 배속별로 최적의 기록파워를 구성할 수 있도록 한 것이다.In each disc information, information indicating a corresponding recording layer and a speed and recording related information WS corresponding to the recording layer and a speed are recorded so that such information can be utilized for recording and reproducing the optical disc. It is possible to configure the recording power of.

이하 도4부터 도9까지를 통해 본발명에서 상기와 같은 디스크정보내에 기록 관련정보(WS)를 기록하는 방법에 대한 다양한 실시예를 상세히 설명하기로 한다.Hereinafter, various embodiments of a method of recording the recording related information WS in the above disc information will be described in detail with reference to FIGS. 4 to 9.

도4는 본발명에 의한 광디스크의 디스크정보를 기록하는 하나의 실시예를 도시한 것으로, 디스크정보의 구조를 간략히 도시한 것이다. 먼저 디스크내에는 복수의 디스크정보가 기록되고 각각의 디스크정보는 일련번호로서 순서를 정해두며, 이를 1바이트(byte)로 기록해둔다. 예를들면 디스크정보내 5번째 바이트에 이 정보를 기록해두고, 이를 "DI frame sequence number in DI block"필드로 명명하고, 간략히 "00h, 01h, 02h ---" 등으로 표현하였다. 즉, 5번째 바이트의 정보가 "00h"이면 첫번째 디스크정보를 의미하며, "07h"이면 8번째 디스크정보임을 의미한다 할 것이다. 또한 상기 5번째 바이트인 "DI frame sequence number in DI block"의 의미를 다음과 같이 정의하는 것도 가능하다. 예를들면, "00h"는 첫번째 디스크정보이자, 제1기록층(Layer0)의 1배속에 대한 디스크정보로 정의하고, "01h"는 두번째 디스크정보이자, 제1기록층(Layer0)의 2배속에 대한 디스크정보로 정의하고, "07h"는 여덟번째 디스크정보이자, 제2기록층(Layer0)의 8배속에 대한 디스크정보로 정의해 두는 것이다. 물론 디스크정보내의 여유영역에 상기 기록층정보와 배속정보는 별도로 기록해 두는 것도 가능하다 할 것이다.Fig. 4 shows one embodiment of recording disc information of an optical disc according to the present invention, and shows a brief structure of the disc information. First, a plurality of pieces of disc information are recorded in the disc, and each piece of disc information is determined as a serial number and recorded in 1 byte. For example, this information is recorded in the fifth byte of the disk information, and this information is named as "DI frame sequence number in DI block" field, and is briefly expressed as "00h, 01h, 02h ---". That is, if the information of the fifth byte is "00h", it means the first disk information, and if it is "07h", it means that it is the eighth disk information. It is also possible to define the meaning of the fifth byte "DI frame sequence number in DI block" as follows. For example, " 00h " is defined as the disk information for the first disk information and 1x speed of the first recording layer Layer0, and " 01h " is the second disk information and 2x speed of the first recording layer Layer0. "07h" is defined as the eighth disc information and the disc information for eight times the speed of the second recording layer (Layer 0). Of course, the recording layer information and the speed information may be separately recorded in the free area of the disk information.

디스크정보내의 특정영역, 예를들어 L~111번째 바이트로 "Write Strategy parameters"필드로 명명한 영역에는 해당 디스크정보가 의미하는 배속에 연동된 기록관련정보(WS)를 기록해 두고, 또 다른 특정영역, 예를들어 N번째 바이트로 "Write Strategy code"필드로 명명한 영역에는 상기 기록된 기록관련정보(WS)의 종류를 식별할 수 있는 식별정보를 기록해 둔다. In a specific area in the disc information, for example, the L-111th byte named the "Write Strategy parameters" field, recording related information WS linked to the double speed of the disc information is recorded. For example, the identification information for identifying the type of the recorded record related information WS is recorded in the area designated by the "Write Strategy code" field as the Nth byte.                     

만약, 기록관련정보(WS)의 종류가 N개 존재한다면, 상기 식별정보는 각각의 기록관련정보(WS)마다 특정 인식값을 할당하게 되고, 예를들어 "0000 0001b"이면 첫번째 WS를 의미하고(Write Strategy-1, WS-1이라고도 한다) , "0000 0010b"이면 두번째 WS를 의미하고(Write Strategy-2, WS-2이라고도 한다) , N의 값에 따라 "XXXX XXXXb"이면 N번째 WS를 의미하는 것으로 (Write Strategy-N, WS-N이라고도 한다) 정의해 두면 된다.If there are N types of record related information WS, the identification information is assigned a specific recognition value for each record related information WS. For example, "0000 0001b" means the first WS. (Write Strategy-1, also called WS-1), "0000 0010b" means the second WS (also known as Write Strategy-2, WS-2), and depending on the value of N, "XXXX XXXXb" means the Nth WS. This is defined as meaning (also called Write Strategy-N, WS-N).

도5는 특정 기록관련정보(WS)에 대해 디스크정보를 기록하는 한 예를 보여주는 것으로, 예를들어 제1기록층의 1배속 디스크정보내에 1배속에 대한 기록관련정보(WS)를 기록함에 있어, 규격화된 여러가지 방식중 디스크제작자가 첫번째WS를 선택적으로 기록해둔 예를 도시한 것이다. 즉, 디스크정보의 N번째 바이트인 "Write Strategy code"필드가 "0000 0001b"로서 첫번째WS(WS-1)를 의미하는 경우 L~111번째 바이트인 "Write Strateg parameters"필드에는 WS-1에 해당하는 파라미터값을 기록해두는 것이다. 도5는 WS-1이 앞서 설명한 "(n-1) Write Strategy"방식인 경우에 이에 해당하는 파라미터값을 예시적으로 보여주는 것이다. 따라서 디스크제작자가 두번째WS를 선택하여 기록하는 경우는 "Write Strategy code"필드는 "0000 0010b"를 기록하고, L~111번째 바이트에는 두번째WS에 적합한 파라미터들이 기록될 것이다. 기록관련정보(WS) 종류에 따라 상기 L~111번째 바이트에 기록되는 파라미터들은 서로 상이한 값을 가짐은 앞서 설명한 바와 동일하며, 해당 기록관련정보(WS) 파리미터들은 디스크의 특성에 맞게 규격화된 정보로서 미리 결정되어 디스크제작자나 시스템 설계자에게 제공될 것이다. 본발명에서는 상기 상세 한 기록관련정보(WS) 파리미터들은 논외의 사항으로 상세한 설명은 생략하기로 한다.FIG. 5 shows an example of recording the disc information for the specific recording related information WS. For example, in recording the recording related information WS for the 1x speed in the 1x speed disc information of the first recording layer, FIG. In this case, the disk maker selectively records the first WS among various standardized methods. That is, when the "Write Strategy code" field, which is the Nth byte of the disk information, is "0000 0001b", which means the first WS (WS-1), it corresponds to WS-1 in the "Write Strateg parameters" field, which is the L to 111th byte. It is to record the parameter value. 5 is a diagram illustrating a parameter value corresponding to the case where WS-1 is the "(n-1) Write Strategy" method described above. Therefore, if the disc maker selects and writes the second WS, the "Write Strategy code" field will record "0000 0010b", and the L-111th bytes will contain the parameters suitable for the second WS. The parameters recorded in the L to 111 th byte according to the type of the recording related information (WS) have different values as described above, and the corresponding recording related information (WS) parameters are standardized according to the characteristics of the disc. It may be predetermined and provided to the disc maker or system designer. In the present invention, the above detailed record related information (WS) parameters are not matters and detailed description thereof will be omitted.

도6,7,8은 상기와 같이 정의된 디스크정보내의 기록관련정보(WS)를 기록하는 방법에 대한 구체적인 실시예를 보여주는 것으로, 도6,7은 모든 기록층 및 배속에 있어 기록관련정보(WS)가 디스크제작시 선택적으로(optional) 선정되어 기록되는 방식을 보여주고, 도8은 특정배속의 경우는 강제적으로(mandatory) 기결정된 기록관련정보(WS)를 기록하는 방식을 보여준다.6, 7 and 8 show a specific embodiment of a method of recording the recording related information WS in the disc information defined as above, and FIGS. 6 and 7 show the recording related information (for all recording layers and speeds). FIG. 8 shows a method in which a WS is selectively selected and recorded at the time of a disc production, and FIG. 8 shows a method of forcibly recording predetermined recording related information WS in a case of a specific speed.

먼저, 도6은 모든 기록층 및 배속에에서 선택적으로 기록관련정보(WS)를 기록할 수 있는 경우로서, 예를들면, 디스크정보 일련순서로서 "00h"에는 제1기록층의 1배속에 관한 디스크정보를 기록하되 기록관련정보(WS)는 첫번째WS(WS-1)을 선택하여 기록하고, "01h"에는 제1기록층의 2배속에 관한 디스크정보를 기록하되 기록관련정보(WS)는 두번째WS(WS-2)을 선택하여 기록하고, "02h"에는 제2기록층의 1배속에 관한 디스크정보를 기록하되 기록관련정보(WS)는 첫번째WS(WS-1)을 선택하여 기록하고, "03h"에는 제2기록층의 2배속에 관한 디스크정보를 기록하되 기록관련정보(WS)는 N번째WS(WS-N)을 선택하여 기록할 수 있음을 보여주고 있다.First, Fig. 6 shows a case in which recording-related information WS can be selectively recorded in all recording layers and double speeds. For example, as a disc information serial sequence, " 00h " Record the disc information, but the recording related information (WS) selects and records the first WS (WS-1), and in "01h", records the disc information about the double speed of the first recording layer, but the recording related information (WS) Select and record the second WS (WS-2), and record the disc information regarding the 1x speed of the second recording layer in " 02h ", while the recording related information (WS) selects and records the first WS (WS-1). &Quot; 03h " shows that the disc information relating to the double speed of the second recording layer is recorded, but the recording related information WS can be recorded by selecting the Nth WS (WS-N).

도7은 선택적으로 기록관련정보(WS)를 기록할 수 있는 또 다른 예로서, 모든 기록층 및 배속에 관한 디스크정보에 동일한 종류의 기록관련정보(WS)를 적용한 경우이다. 즉, 선택적으로 기록관련정보(WS)를 기록가능하므로, 디스크제작자는 가장 신뢰할 수 있는 하나의 기록관련정보(WS) 방식에 대해 모든 디스크정보를 동일하게 적용하는 것도 가능하며, 도7은 첫번째WS(WS-1)이 모든 디스크정보에 기록된 경우 를 보여주고 있다.Fig. 7 is another example in which the recording related information WS can be selectively recorded, which is the case where the same kind of recording related information WS is applied to all the recording layers and the disc information regarding the speed. That is, since it is possible to selectively record the recording related information WS, the disc producer can apply all the disc information equally to the most reliable one of the recording related information WS methods, and FIG. 7 shows the first WS. Shows the case where (WS-1) is recorded in all the disc information.

도8은 특정배속의 경우는 강제적으로(mandatory) 기결정된 기록관련정보(WS)를 기록하고, 나머지배속에 대해서는 선택적으로(optional) 기록관련정보(WS)를 기록하는 방식을 보여주는 것으로, 일반적으로 1배속에 대한 기록관련정보(WS)는 가장 중요한 기록관련정보(WS)로서 규격화된 결정으로 특정 방식을 미리 결정해두고, 1배속을 제외한 나머지 배속은 디스크제작자가 선택적으로 기록가능하도록 한 것이다. 예를들어, 1배속에 강제되는 기록관련정보(WS) 종류가 첫번째WS(WS-1)이라면, 디스크정보 일련순서로서 "00h"에는 제1기록층의 1배속에 관한 디스크정보를 기록하되 기록관련정보(WS)는 첫번째WS(WS-1)을 반드시 기록하고, "01h"에는 제1기록층의 2배속에 관한 디스크정보를 기록하되 기록관련정보(WS)는 선택적으로 기록가능하여, 두번째WS(WS-2)을 선택하여 기록한 것이고, "02h"에는 제2기록층의 1배속에 관한 디스크정보를 기록하되 기록관련정보(WS)는 첫번째WS(WS-1)을 반드시 기록하고, "03h"에는 제2기록층의 2배속에 관한 디스크정보를 기록하되 기록관련정보(WS)는 선택적으로 기록가능하여, 두번째WS(WS-2)을 선택하여 기록한 것음을 보여주고 있다. FIG. 8 shows a method of forcibly recording predetermined record related information WS for a specific speed, and optionally recording information WS for the remaining speed. The recording related information (WS) for the 1x speed is the most important recording related information (WS), which is a standardized decision, and a specific method is determined in advance, and the other speeds except for the 1x speed are made available for selective recording by the disc producer. For example, if the type of recording related information WS enforced at 1x speed is the first WS (WS-1), the disc information regarding the 1x speed of the first recording layer is recorded in "00h" as the disc information serial sequence. The related information WS always records the first WS-WS-1, and in " 01h ", the disc information relating to the double speed of the first recording layer is recorded, but the record related information WS is selectively recordable. In the "02h", the disc information about the 1x speed of the second recording layer is recorded, and the recording related information (WS) always records the first WS (WS-1). 03h "shows that the disc information relating to the double speed of the second recording layer is recorded, but the recording related information WS is selectively recordable, so that the second WS WS-2 is selected and recorded.

따라서, 도8의 경우를 적용시, 규격화된 복수의 기록관련정보(WS)중, 기본이 되는 1배속 기록관련정보(WS)는 강제적으로 어느하나를 통일적으로 기록하게 하여 디스크 기록특성을 더욱 보장하게 되고, 1배속이외의 나머지 배속에 대해서는 규격화된 복수의 기록관련정보(WS)중 어느하나를 디스크제작자가 선택적으로 기록할 수 있게 하여 디스크제작시간을 줄여주는 장점이 있게 된다. Therefore, in the case of applying the case of Fig. 8, of the standardized recording related information WS, the basic 1x speed recording related information WS is forced to uniformly record any one to further ensure the disc recording characteristics. For the remaining speed other than 1x speed, any one of the standardized record related information WS can be selectively recorded by the disc producer, thereby reducing the disc production time.                     

아울러, 상기 도8의 경우에서 특정경우에는 1배속에 대한 강제 기록관련정보 (WS)를 기록함과 별도로, 1배속에 대해 디스크제작자가 선택적으로 다른 기록관련정보(WS)를 기록하는 것도 가능하며, 이경우 1배속에 대한 디스크정보는 규격화된 강제 기록관련정보(WS)를 포함하는 디스크정보와 이와 상이한 선택적 기록관련정보(WS)를 포함하는 디스크정보가 각각 존재하게 된다. In addition, in the case of FIG. 8, in a specific case, in addition to recording forced recording related information (WS) at 1x speed, it is also possible for the disc producer to selectively record other recording related information (WS) at 1x speed. In this case, the disc information for the 1x speed includes disc information including standardized forced recording related information (WS) and disc information including different selective recording related information (WS).
