Abstract

PURPOSE: A method of recording data of an optical disk is provided to improve recorded data by varying a pre-stored writing strategy and performing recording action. CONSTITUTION: If an optical capable of recording one time is inserted and secured, and driven(S10), a microcomputer confirms the starting time of a lead-in area and a lead-out area from TOC(Table Of Contents) recorded in the lead-in area of the optical disk(S11). The microcomputer outputs track pitch of the optical disk from the confirmed starting time of the lead-in and lead-out areas(S12). The microcomputer confirms a writing strategy corresponding to a discriminated manufacturing company from the data about the writing strategy stored in the inner ROM of the microcomputer(S13). If recording action is demanded(S20), recording action of data is performed(S32), basing on the optimum recording power value of the optical disk and the confirmed writing strategy, when the output track pitch value is the reference value(S30). If the output track pitch value is under the reference value, the microcomputer maintains the signal level of recording pulse according to the confirmed writing strategy, and varies and records the duration of the recording pulse according to the output track pitch(S31). Recording action is continuously performed until the commanded recording action is finished(S40).

Description

광디스크의 데이터 기록방법{Method for recording the data on a optical disc}Method for recording the data on a optical disc

본 발명은, 광디스크 제조사 및 트랙폭에 대응되는 최적의 기록방식(write strategy)에 근거하여 기록동작이 이루어지도록 하는 광디스크의 데이터 기록방법에 관한 것이다.The present invention relates to a data recording method of an optical disc, in which a recording operation is performed based on an optical disc manufacturer and an optimal write strategy corresponding to a track width.

일반적으로, 광디스크의 데이터 기록시에 필요한 정보인 기록방식(write strategy)은 광디스크 제조사별로 그 값이 상이하므로, 광디스크 구동장치 내의 마이컴에 광디스크 제조사별로 대응되는 기록방식에 대한 정보를 저장하여, 상기 광디스크 구동장치가 삽입된 광디스크의 제조사를 판단하여 그에 대응되는 기록방식을 이용하여 기록동작을 수행하도록 하였다.In general, since a write strategy, which is information required for data recording of an optical disc, has a different value for each optical disc manufacturer, information on a recording method corresponding to each optical disc manufacturer is stored in a microcomputer in the optical disc drive device, thereby storing the optical disc. The manufacturer of the optical disc in which the driving apparatus is inserted is determined and a recording operation is performed by using a recording method corresponding thereto.

그러나, 광디스크의 트랙피치(Track Pitch : 트랙폭)는 광디스크의 데이터 기록용량에 따라 상이한데, 즉 데이터 기록용량이 74분인 광디스크인 경우에는 트랙피치가 약 1.6μm이지만 데이터 기록용량이 80분인 광디스크의 경우에는 트랙피치가 데이터 기록용량이 74분인 광디스크에 비해 작은 값을 갖게 된다.However, the track pitch (track width) of an optical disc differs depending on the data recording capacity of the optical disc, i.e., in case of an optical disc with a data recording capacity of 74 minutes, the track pitch is about 1.6 탆 but an 80 minute data recording capacity of an optical disc. In this case, the track pitch has a smaller value than that of an optical disc whose data recording capacity is 74 minutes.

그럼에도 불구하고, 종래에는 데이터 기록용량이 74분인 경우, 즉 트랙피치가 약 1.6μm 경우만을 고려하여 기록방식을 결정 저장하게 되므로, 만약 광디스크의 트랙피치가 1.6μm 보다 작은 경우, 즉 데이터 기록용량이 80분인 광디스크인경우에는, 트랙피치가 1.6μm인 광디스크를 기준으로 결정된 기록방식에 근거하여 기록동작을 수행하게 되면, 광디스크의 외주에서 스퍼터링(Sputtering)에 따른 심한 열화현상이 발생할 수 있는 문제점이 있었다.Nevertheless, conventionally, the recording method is determined and stored only when the data recording capacity is 74 minutes, that is, when the track pitch is about 1.6 μm. Therefore, if the track pitch of the optical disc is smaller than 1.6 μm, that is, the data recording capacity is In the case of an 80-minute optical disc, if the recording operation is performed based on the recording method determined based on the optical disc having a track pitch of 1.6 μm, there is a problem that severe deterioration may occur due to sputtering on the outer periphery of the optical disc. .

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 창작된 것으로서, 트랙피치가 기준값(1.6μm) 보다 작은 광디스크에 대해서는, 기 저장된 기록방식을 가변시켜 기록동작을 수행함으로써, 기록데이터에 대한 품질이 향상되도록 하는 광디스크의 데이터 기록방법을 제공하는 데 그 목적이 있는 것이다.Accordingly, the present invention was created to solve the above problems, and for an optical disc having a track pitch smaller than a reference value (1.6 μm), the recording operation is performed by varying the pre-stored recording method, whereby the quality of the recorded data is improved. It is an object of the present invention to provide a data recording method of an optical disc that is to be improved.

Hereinafter, the data recording method of FIG. 2 according to the present invention will be described in detail with reference to the configuration of FIG.

우선, 상기 마이컴(80) 내부 롬(ROM)(81)에 각 디스크 제조사별 대응되는 기록방식에 대한 정보가 기 저장되어 있는 상태에서, 1회 기록가능한 광디스크(CD-R)(10)가 삽입안착되어(S10) 회전구동되면, 상기 마이컴(80)은 상기 광디스크(10)의 리드인 영역상에 기록되어 있는 TOC(Table Of Contents) 정보로 부터 리드인(Lead-in) 영역의 시작시간(Start Time) 및 리드아웃(Lead-out) 영역의 시작시간을 확인하게 되는데(S11), 상기 리드인 영역은 물리적으로 구분 할당되어, 디스크 외주 방향으로 점차 증가하는 절대시간정보, 다수의 스페셜 정보들(Special Information 1,2,3)과 일반 시간코드들(Normal Time Code)이 포함 기록되는데, 상기 리드인 영역에서의 N+20 번째 프레임에 기록되는 제3 스페셜 정보는, 분(Minutes), 초(Seconds), 프레임(Frames)을 나타내는 총 3 바이트의 절대시간정보로서, 상기 광디스크(10)의 프로그램 영역의 최종 기록위치, 즉 물리적으로 구분 할당되는 리드아웃 영역의 시작위치에 대응되는 절대시간정보가 기록된다. 예를 들어, 상기 제3 스페셜 정보의 3 바이트 값이 '0111 0000, 0100 0101, 0001 0101'인 경우, 물리적으로 구분 할당되는 리드아웃 영역의 시작위치에 대응되는 절대시간정보는, '70:45:15' 즉 70분 45초 15프레임이 되는 것이다.First, an optical disc (CD-R) 10 that can be written once is inserted in a state where information on a recording method corresponding to each disc manufacturer is pre-stored in the ROM 81 of the microcomputer 80. When it is seated (S10) and rotated, the microcomputer 80 starts the start time (Lead-in) of the lead-in area from the TOC (Table Of Contents) information recorded on the lead-in area of the optical disc 10. Start time) and the start time of the lead-out area are checked (S11), and the lead-in area is physically divided and thus the absolute time information gradually increasing in the circumferential direction of the disc and a plurality of special informations. (Special Information 1,2,3) and Normal Time Codes are recorded, and the third special information recorded in the N + 20th frame in the lead-in area is minutes and seconds. (Seconds), absolute time information of a total of three bytes representing the Frame (Frames), the optical The absolute time information corresponding to the last recording position of the program area of the disc 10, that is, the start position of the lead-out area which is physically divided and allocated, is recorded. For example, when the 3-byte value of the third special information is' 0111 0000, 0100 0101, 0001 0101 ', the absolute time information corresponding to the start position of the lead-out area that is physically allocated is '70: 45'. : 15 'That is, 70 minutes 45 seconds 15 frames.

이어서 상기 마이컴(80)은 상기 확인된 리드인 영역의 시작시간으로 부터 상기 광디스크(10)의 제조사를 판별하게 되는데, 각 광디스크 제조사마다 리드인의 시작시간이 다르기 때문에 이로 부터 광디스크 제조사를 쉽게 판별할 수 있게 된다.Subsequently, the microcomputer 80 determines the manufacturer of the optical disc 10 from the start time of the identified lead-in area. Since the start time of the lead-in is different for each optical disc manufacturer, the optical disc manufacturer can be easily determined from this. It becomes possible.

또한, 상기 마이컴(80)은 상기 확인된 리드인 영역의 시작시간 및 리드아웃 영역의 시작시간으로 부터 상기 광디스크(10)의 트랙피치를 산출하게 되는데(S12),만약 상기 광디스크(10)의 기록용량이 74분인 경우에는 트랙피치 값은 기준값(약 1.6μm)이고, 상기 광디스크(10)의 기록용량이 80분인 경우에는 트랙피치 값은 상기 기준값 보다 소정값 이상 작게 산출된다.In addition, the microcomputer 80 calculates the track pitch of the optical disc 10 from the start time of the identified lead-in area and the start time of the lead-out area (S12), if the recording of the optical disc 10 When the capacity is 74 minutes, the track pitch value is a reference value (about 1.6 µm), and when the recording capacity of the optical disc 10 is 80 minutes, the track pitch value is calculated to be smaller than the reference value by a predetermined value or more.

상기 광디스크(10)의 제조사가 판별되면, 상기 마이컴(80)은 내부 롬(81)에 저장되어 있는 기록방식에 대한 정보로 부터 상기 판별된 제조사에 대응되는 기록방식을 확인하게 된다(S13).When the manufacturer of the optical disc 10 is determined, the microcomputer 80 checks the recording method corresponding to the determined manufacturer from the information on the recording method stored in the internal ROM 81 (S13).

이와 같은 상태에서 기록동작이 요청되면(S20), 상기 마이컴(80)은 상기 산출된 트랙피치 값을 확인하여 트랙피치 값이 기준값(약 1.6μm)인 경우에는(S30), OPC(Optimum Power Control) 동작 수행에 따라 검출된 상기 광디스크(10)에 대한 최적 기록 광파워값과 상기 확인된 기록방식에 근거하여 데이터 기록동작이 이루어지도록 하고(S32), 만약 상기 산출된 트랙피치 값이 상기 기준값 보다 소정값 이상 작은 경우에는, 상기 마이컴(80)은 기록펄스의 신호레벨은 상기 확인된 기록방식에 따라 유지시키되, 기록펄스의 지속시간(duration)은 상기 산출된 트랙피치에 따라 가변시켜 데이터를 기록하도록 하는데(S31), 이에 근거한 기록동작을 보다 상세히 설명하면 다음과 같다.When a recording operation is requested in such a state (S20), the microcomputer 80 checks the calculated track pitch value, and when the track pitch value is a reference value (about 1.6 μm) (S30), OPC (Optimum Power Control) The data recording operation is performed based on the optimal recording optical power value for the optical disc 10 and the confirmed recording method detected according to the operation (S32), and if the calculated track pitch value is greater than the reference value, When the predetermined value is smaller than the predetermined value, the microcomputer 80 maintains the signal level of the recording pulse according to the confirmed recording method, but the duration of the recording pulse varies according to the calculated track pitch to record the data. (S31), the recording operation based on this will be described in detail as follows.

우선, 상기 디지털 기록신호 처리부(30a)는 입력되는 부호화된 데이터의 기록/재생의 신뢰성을 위한 엔코딩 및 초점에러정정 패리티(Parity)를 부가하여 초점에러정정코드(ECC Block) 등을 생성하게 되고, 상기 채널비트 엔코더(40)는 상기 디지털 기록신호 처리부(30a)에서 출력되는 디지털 비트스트림을 상기 광디스크(10)에 기록하기 위한 펄스폭 변조된 신호형태로 변환하여 상기광구동기(41)에 인가하며, 상기 마이컴(80)은 상기 검출된 최적 기록 광파워값에 상응하는 광 구동전류에 의해 기록신호가 출력되도록 상기 광구동기(41)를 제어한다. 이에 따라 상기 광구동기(50)는 상기 인가되는 펄스폭 변조된 신호에 대응되는 광 구동전력으로 기록데이터에 대한 신호를 출력시켜, 상기 광픽업(20)이 상기 광디스크(10)의 프로그램에 영역에 상기 데이터를 기록하도록 한다. 이때 상기 산출된 트랙피치 값이 상기 기준값 보다 소정값 이상 작은 경우에는, 상기 마이컴(80)은 상기 광픽업(20)으로 하여금 기록펄스의 신호레벨은 상기 확인된 기록방식에 따라 유지시키되, 기록펄스의 지속시간(duration)을 그 작은 만큼에 비례하여 증가시키면서 기록동작을 수행하게 되는데(S31), 즉 도3에 도시된 기록펄스의 예에서와 같이, 상기 산출된 트랙피치 값이 상기 기준값 보다 작은 경우에는 그 작은 만큼에 비례하여 증가시켜야 할 지속시간의 크기 Δ(Δ=k= k', k 및 k'는 비레상수)를 산출하여 산출된 Δ만큼 기록펄스의 지속시간을 증가시켜 기록동작을 수행하게 되며, 이와 같은 기록동작은 요청된 기록동작이 완료될 때까지 계속해서 이루어지게 된다(S40).First, the digital recording signal processor 30a generates a focus error correction code (ECC Block) by adding an encoding and a focus error correction parity for reliability of recording / reproducing the input coded data. The channel bit encoder 40 converts the digital bitstream output from the digital recording signal processing unit 30a into a pulse width modulated signal for recording on the optical disc 10 and applies it to the optical driver 41. The microcomputer 80 controls the optical driver 41 to output a recording signal by an optical driving current corresponding to the detected optimal recording optical power value. Accordingly, the optical driver 50 outputs a signal for recording data at an optical driving power corresponding to the applied pulse width modulated signal, so that the optical pickup 20 is applied to a program area of the optical disc 10. Record the data. At this time, when the calculated track pitch value is smaller than the reference value by more than a predetermined value, the microcomputer 80 causes the optical pickup 20 to maintain the signal level of the recording pulse in accordance with the confirmed recording method. The recording operation is performed while increasing the duration of the recording in proportion to the smaller (S31). That is, as in the example of the recording pulse shown in Fig. 3, the calculated track pitch value is smaller than the reference value. In this case, the magnitude of the duration Δ (Δ = k) = k ' , k and k 'are non-regular constants) to increase the duration of the recording pulse by the calculated Δ to perform the recording operation. Such recording operation is continued until the requested recording operation is completed. (S40).
