Abstract

1. 청구범위에 기재된 발명이 속한 기술분야.1. The technical field to which the invention described in the claims belongs.

기록 가능한 광디스크에 데이타를 기록하는 방법에 관한 것이다.A method of recording data on a recordable optical disc.

2. 발명이 해결하려고 하는 기술적 과제.2. The technical problem that the invention is trying to solve.

비정상적인 데이타 기록상태에서 광디스크에 데이타를 기록하는 경우에 손실되던 이전에 기록된 데이타들을 보호하기 위한 것이다.It is for protecting previously recorded data lost when data is recorded on the optical disc in an abnormal data recording state.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

본 발명에 따른 기록가능한 광디스크의 데이타 기록방법은 실제 기록을 위한 데이타를 광디스크에 기록하기 이전에 미리 설정된 후 저장되어 있는 설정데이타를 이용하여 광디스크에 데이타를 정상적으로 기록할 수 있는지 여부를 확인하는 가상 기록모드와, 상기 가상 기록모드에서 정상적인 데이타의 기록이 가능한 것으로 확인된 경우 광디스크에 입력되는 데이타를 실제 기록하는 실제 기록모드로 구성된다.In the data recording method of a recordable optical disc according to the present invention, virtual recording is performed to confirm whether data can be normally recorded on the optical disc using setting data stored in advance after being recorded before recording data for actual recording on the optical disc. Mode and an actual recording mode for actually recording data input to the optical disc when it is confirmed that normal data can be recorded in the virtual recording mode.

4. 발명의 중요한 용도4. Important uses of the invention

실제 기록을 위한 데이타를 디스크에 기록하기 이전에 미리 설정된 후 저장되어 있는 설정데이타를 이용하여 디스크에 데이타를 정상적으로 기록할 수 있는지 여부를 확인할 수 있고, 비정상적 데이타의 기록상태에서도 기존에 디스크상에 기록되어 있는 데이타들을 보호할 수 있다.It is possible to check whether the data can be recorded normally on the disk by using the setting data stored in advance before recording the data for actual recording on the disk. Secure data.

Claims

A method of recording data on an optical disc constituted by a data recording area for recording input data, and a related information recording area for recording information relating to data recorded in the data recording area. A data recording process for recording input data and comparing the input data recorded in the data recording area with the input data before recording information related to the input data recorded in the data recording process in the related information recording area; A data recording method comprising the data comparison process.

The data recording area of claim 1, wherein in the data comparison process, when the input data and the input data recorded in the data recording area are compared with the same data, subsequent input data is recorded in the data recording area and simultaneously recorded in the data recording area. And recording information relating to the recorded data into the related information recording area.

A buffer RAM storing preset data and storing data input from the outside; And at least an optical disc configured with a data recording area for recording data output from the buffer RAM, and an associated information recording area for recording information relating to data recorded in the data recording area. In the method for recording; A setting data recording process of recording setting data stored in the buffer RAM in the data recording area before storing the input data in the buffer RAM; A setting data comparison process of comparing the setting data recorded in the setting data recording area with the setting data stored in the buffer RAM; When the setting data recorded in the setting data recording area and the setting data stored in the buffer RAM are compared with each other during the setting data comparison process, the data input from the outside is temporarily stored in the buffer RAM and then stored in the data recording area. A data recording method comprising the input data recording process for recording.

4. The data recording according to claim 3, further comprising a recording data related information recording process of recording the input data in the data recording area and simultaneously recording information related to the input data in the related information recording area. Way.

5. The method of claim 4, wherein when the setting data is compared with the setting data stored in the setting data recording area and the setting data stored in the buffer RAM are not the same, recording on the optical disc is impossible. Data recording method.
