Claims (2)
- 회전형 기억장치의 복수의 헤드와 기록매체의 복수의 트랙과의 사이에서 동시에 데이터를 전송하는 회전형 기억장치의 제어방법에 있어서, 어느 트랙에 불량섹터가 있는 경우에 복수개의 트랙의 각 센터에 레코드를 논리적으로 배열하는 순서로 보아 당해 분량섹터의 다음에 나타나는 양호섹터에 교대섹터를 할당하도록 한 회전형 기억장치의 제어방법.
- 제1항에 있어서, 각 센터에 당해 섹터가 양호한지의 여부 및 당해섹터가 속하는 트랙 위에서 기록된 경우의 다음의 섹터가 양호한지의 여부를 나타내는 식별정보를 기록하고, 데이터판독서에 섹터가 상기 식별정도로부터 불량이라고 검출된 때에는 상기 논리적 배열순서로 보아 당해 불량섹터의 다음에 나타나는 양호 섹터로 부터의 데이터를 불량섹터로부터의 데이터 대신 받아들이고, 데이터 기입시에 상기 식별 정보로부터 다음의 섹터가 불량이라고 검출된 때에는 상기 논리적 배열순서로 보아 당해 불량섹터의 다음에 나타나는 양호섹터에 불량섹터에의 데이터기입 대신에 데이터를 기입하는 회전형 기억장치의 제어방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
