Description
도 1은 본 발명 광기록재생장치의 기록 배속 설정 방법에 의한 동작을 보인 흐름도.1 is a flowchart showing the operation by the recording double speed setting method of the optical recording and reproducing apparatus of the present invention.
본 발명은 광기록재생장치의 기록 배속 설정 방법에 관한 것으로, 특히 기록용 디스크에 데이터를 기록하기 전에 해당 디스크에 기록가능한 최고 배속을 검사하여 최적의 기록 배속으로 기록함으로써 서보의 트랙 이탈이나 포커스 드롭을 방지하도록 한 광기록재생장치의 기록 배속 설정 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording speed setting method of an optical recording / reproducing apparatus. In particular, before recording data on a recording disc, the track's track deviation or focus drop can be recorded by checking the maximum recording speed that can be recorded on the disk and recording at the optimal recording speed. The present invention relates to a recording speed setting method of an optical recording and reproducing apparatus.
일반적인 광기록 재생 장치를 통해 디스크에 데이터를 기록하고자 하는 경우, 기록 배속을 결정함에 있어 사용자가 테스트 앤 카피 모드(Test & Copy Mode)로 테스트 기록을 수행하여 기록 실패 여부를 미리 검사하게 된다.When data is to be recorded on a disc through a general optical recording and reproducing apparatus, in determining the recording speed, the user performs test recording in a test & copy mode to check whether the recording has failed.
여기서, 상기 테스트 앤 카피 모드는 데이터를 기록할 디스크의 영역을 실제 기록 파워로 기록하는 것이 아니라 재생 파워로 설정된 배속으로 미리 기록 동작을 수행하여 에러가 발생되는 영역이 있는지 판단하여 설정된 배속으로 기록이 가능한지 판단하게 된다.Here, the test and copy mode does not record the area of the disc on which data is to be recorded at the actual recording power, but performs a recording operation in advance at a double speed set as the reproduction power to determine whether there is an area in which an error occurs. Determine if possible.
이때, 사용자는 상기 테스트 앤 카피 모드 동작중 에러가 발생하는지를 직접 일일이 확인하여 최적의 기록 배속을 판단하게 되고, 이에 상기 사용자가 에러가 발생하지 않는다고 판단한 기록 배속으로 상기 디스크에 데이터를 기록하게 된다.In this case, the user directly checks whether an error occurs during the test and copy mode operation, and determines an optimal recording speed, thereby recording data on the disc at a recording speed determined that the error does not occur.
여기서, 상기 테스트 앤 카피 모드를 통해 설정한 기록 배속으로 상기 디스크에 데이터를 기록시 디스크 자체의 불량으로 서보가 이탈하여 기록이 실패할 경우가 종종 발생되며, 이 문제는 8배속 이상의 고배속으로 디스크에 데이터를 기록시 더욱 심각 하게 발생하게 된다.In this case, when the data is written to the disc at the recording speed set by the test and copy mode, the servo is disengaged due to the failure of the disc itself, and the recording often occurs. This problem occurs in the disc at the high speed of 8 times or more. This happens more seriously when recording data.
따라서, 상기와 같이 종래 기록용 디스크에 데이터를 기록함에 있어서 고배속으로 갈수록 상기 기록용 디스크 자체의 불량으로 인하여 서보가 트랙을 이탈하거나 포커스의 드롭이 발생함에 따라 기록에 실패하게 되며, 이를 방지하기 위하여 사용자가 기록할 디스크의 기록 배속을 일일이 기록 실패 여부를 판단하여 설정함으로써, 상기 기록 배속의 설정이 매우 번거로운 문제점이 있었다.Therefore, as the data is recorded on the conventional recording disk as described above, the recording fails as the servo leaves the track or the focus drops due to the failure of the recording disk itself at higher speeds. By determining and setting the recording speed of the disc to be recorded by the user, the setting of the recording speed is very troublesome.
따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 창안한 것으로, 기록용 디스크에 데이터를 기록하기 전에 상기 디스크에 기록가능한 최고 배속을 검사하여 서보의 트랙 이탈이나 포커스 드롭을 방지함으로써 최적의 기록 배속을 설정하도록 한 광기록재생장치의 기록 배속 설정 방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been devised to solve the above-mentioned conventional problems. The present invention is optimized by checking the maximum speed that can be recorded on the disk before recording data on the recording disk, thereby preventing the servo from moving out of the track or focus drop. It is an object of the present invention to provide a recording speed setting method of an optical recording / reproducing apparatus for setting the recording speed.
상기와 같은 목적을 달성하기 위한 본 발명은 최고 기록 배속으로 검사 배속을 설정하는 제1 단계와; 상기 설정된 검사 배속으로 디스크를 회전시키면서 서보의 이상상태 여부를 판단하는 제2 단계와; 상기 제2 단계의 판단결과 서보의 이상 상태가 감지되면 현재 검사 배속을 낮게 설정하여 상기 제2 단계를 반복수행하고, 상기 판단 결과 서보의 이상 상태가 없으면, 상기 검사배속을 최고 기록 배속으로 설정하는 제3 단계로 이루어진 것을 특징으로 한다.The present invention for achieving the above object comprises a first step of setting the inspection speed to the highest recording speed; A second step of determining whether or not the servo is in an abnormal state while rotating the disc at the set inspection speed; If the abnormal state of the servo is detected as a result of the determination of the second step, the current inspection speed is set to a low value, and the second step is repeated. If the abnormality of the servo is not found, the inspection speed is set to the highest recording speed. It is characterized by consisting of a third step.
이하, 본 발명에 따른 일실시예에 대한 동작과 작용효과를 첨부한 도 1을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to Figure 1 attached to the operation and effect for one embodiment according to the present invention will be described in detail.
우선, 사용자가 디스크 검사모드를 설정하여 로딩된 디스크에 적합한 기록 배속을 검사할 것인지를 판단하여(S1) 상기 디스크 검사모드의 수행을 원하지 않는 경우, 기록 가능한 최고 배속을 기록 배속으로 설정하여 기록을 수행한다.(S2)First, if the user sets the disc check mode to determine whether to check the recording speed suitable for the loaded disc (S1), and if the user does not want to perform the disc check mode, the recording is performed by setting the maximum record speed to the recording speed. (S2)
그러나, 상기 사용자가 디스크 검사 모드를 수행하고자 하는 경우, 우선, 최고 기록 배속으로 검사 배속을 설정하고(S3), 상기 디스크에 기록 영역과 미기록 영역을 확인하여(S4) 디스크상에서 상기 미기록 영역의 시작 어드레스를 탐색하여 이동한다.(S5)However, when the user wants to perform the disc test mode, first, the test speed is set to the highest recording speed (S3), the recording area and the unrecorded area are checked on the disc (S4), and the start of the unrecorded area on the disc is started. The address is searched and moved (S5).
이때, 상기 디스크 검사 모드의 설정은 사용자가 수동으로 설정할 수도 있으며, 광기록재생장치에서 상기 기록용 디스크 삽입 후 소정의 유휴 시간을 이용하여 자동으로 수행하도록 설정할 수도 있다.In this case, the disc checking mode may be set manually by the user, or may be set to be automatically performed by the optical recording / reproducing apparatus using a predetermined idle time after the recording disc is inserted.
여기서, 상기 이동한 미기록 영역의 시작 어드레스가 디스크 최종 어드레스일 경우, 더 이상 기록할 영역이 없으므로 현재 검사 배속을 기록 배속으로 설정하여 기록을 수행한다(S6).Here, when the start address of the moved unrecorded area is the last address of the disc, since there is no more area to record, recording is performed by setting the current inspection speed to the recording speed (S6).
그러나, 상기 이동한 어드레스가 최종 어드레스가 아니면, 현재 이동한 어드레스부터 정상 플레이 백(Normal Play Back) 검사를 수행하여(S7) 서보의 이상 상태를 판단한다.(S8)However, if the moved address is not the final address, the normal play back test is performed from the current moved address (S7) to determine an abnormal state of the servo. (S8)
이때, 상기 서보의 이상 상태는 서보의 트랙 이탈이나 포커스 드롭 현상의 발생 여부를 통해 판단한다.In this case, the abnormal state of the servo may be determined based on whether the servo is out of track or a focus drop occurs.
이에, 상기 디스크 최종 어드레스까지 상기 서보의 이상 상태가 발생하지 않으면, 현재 검사 배속을 기록할 기록 배속으로 설정하여 기록 동작을 수행한다.Therefore, if the servo abnormal state does not occur until the disc last address, the write operation is performed by setting the current inspection speed to the recording speed to be recorded.
그러나, 상기 정상 플레이백 검사를 수행중 서보의 이상 상태가 발생되면, 해당 어드레스를 서보 드롭 어드레스로 저장한 후(S9) 현재 검사 배속을 한단계 낮은 기록 배속으로 설정한다.(S10)However, if an abnormal state of the servo occurs during the normal playback check, the address is stored as the servo drop address (S9) and the current check speed is set to a lower recording speed (S10).
그리고, 상기 저장된 서보 드롭 어드레스로 다시 이동한 후(S11), 상기 재설정된 기록 배속으로 이동한 어드레스부터 다시 정상 플레이 백 검사를 수행하고, 이에 상기 서보의 트랙 이탈이나 포커스 드롭이 최종 어드레스까지 발생하지 않으면, 현재 검사 배속을 기록 배속으로 설정한다.Then, after moving back to the stored servo drop address (S11), the normal playback check is performed again from the address moved to the reset recording speed, and thus, the track deviation or the focus drop of the servo does not occur until the final address. If not, the current inspection speed is set to the recording speed.
그러나, 다시 상기 서보의 이상 상태가 발생되면, 상기 검사 배속을 한단계 낮게 설정하여 상기 동작을 재반복한다.However, when the abnormal state of the servo occurs again, the inspection double speed is set one level lower to repeat the operation.
상기에서 상세히 설명한 바와 같이, 본 발명은 최고 검사 배속 모드에서 출발하여 서보 이탈이 되지 않는 최고 배속을 단계적으로 찾아가는 알고리즘을 통해 고배속으로 갈수록 기록용 디스크 자체의 불량으로 인해 발생되는 서보의 트랙 이탈이나 포커스 드롭을 방지하는 효과가 있다.As described in detail above, the present invention starts with the highest inspection speed mode and finds the highest speed at which the servo does not go out step by step through the algorithm of the servo track deviation or focus caused by the failure of the recording disk itself at higher speeds. It has the effect of preventing drop.
