Abstract

본 발명은 기록데이터 검증방법에 관한 것으로, 특히 미니디스크 시스템에서 기록시 자체 보유하고 있는 쇼크 방지 메모리를 시간 기준 제어하여 기록 데이터를 다시 재생시켜 비교 확인할 수 있도록 한 미니디스크 시스템의 기록데이터 검증방법에 관한 것이다.The present invention relates to a method for verifying recorded data, and more particularly, to a method for verifying recorded data of a mini-disc system, which enables the comparison and reconstruction of the recorded data by controlling the shock-resistant memory owned when recording in the mini-disc system based on time. It is about.

종래의 기술은 기록되는 데이터가 정확히 원하는 포인트에 기록되었는가의 신뢰성 판단은 기록시 디스크에 기록되어 있는 어드레스가 연속되는 가로 판단되므로 기록데이터의 신뢰성 판단은 실제 기록데이터의 신뢰성 판단으로는 부족하며, 그에 따른 오기록의 발생 우려가 많았다.In the prior art, since the reliability judgment of whether the data to be recorded is recorded at the desired point exactly is the horizontal judgment of the address recorded on the disk at the time of recording, the reliability determination of the recording data is insufficient for the reliability determination of the actual recording data. There were many concerns about the occurrence of false records.

따라서 본 발명은 미니디스크상에 기록되어 있는 어드레스 단위로 기록을 행하고 버퍼링램에 검증영역을 할당하여 기록데이터를 재생시켜 그 재생 데이터와 기록하고자 하는 데이터를 비교 판단하므로써 데이터가 기록되지 않은 경우 재 기록을 행하여 기록데이터의 신뢰성을 향상시키는 기록데이터 검증방법을 제공한 것이다.Therefore, according to the present invention, recording is performed in units of addresses recorded on the mini-disc, the verification area is allocated to the buffering RAM to reproduce the recorded data, and the data is not recorded by judging and comparing the reproduced data with the data to be recorded. By providing a method for verifying the recording data to improve the reliability of the recording data.

Claims

Allocate a verification area corresponding to the amount of data recorded at one address of the disk to the RAM used for buffering, and the first pointer (Pt 1) for addressing the data input to the RAM from the data compressor / extension device and the digital at the RAM. A first step (S11-S16) of temporarily storing write data in the RAM buffering area by the first pointer by setting a second pointer Pt2 for addressing data output to the signal processor; Recognizing the difference between the two pointers formed in the step, the second step (S17, S18) of reading the write data for one address on the disk from the RAM buffering area and writing to the corresponding address on the disk, and the write data of the second step The third step (S19-S21) of simultaneously reading the buffering area and the address of the verification area on the RAM while sequentially reproducing The fourth step of comparing the data of the two addresses in step 3 and recording the next data to be recorded at the next address of the disc when they are the same, and returning to the second step to rewrite the data which has been recorded at the current address of the disc if they are not the same ( S22-S26) recording data verification method of the mini-disc system characterized in that consisting of.
