Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. Technical field to which the invention described in the claims belongs

자기디스크 기록장치의헤드 위치정보에 있어서, 특히 서보섹터내의 버스트 정보영역 이외의 별도의 서브-버스트(Sub-burst이하 서브-버스트라 함)를 기록하여 위치정보를 개선할 수 있는 기록매체에 관한 것이다.A recording medium capable of improving position information by recording another sub-burst (sub-burst (sub-burst)) other than the burst information area in the servo sector in the head position information of the magnetic disk recording apparatus will be.

2. 발명이 해결하고자 하는 기술적 과제2. Technical Problems to be Solved by the Invention

현재의 기술추이상 점차 고용량의 디스크 구동 기록장치를 필요로함에 따라 첫번째 서보섹터에서 위치정보를 샘프링한 후 다음 서보섹터에서 위치정보를 샘플링 할때까지의 샘플링타임이 되기전에 외부충격이나 기타요인에 의해 해드의 오프트랙이 심해져 에러가 발생할 수 있었던 문제점을 해결한다.It is necessary to sample the position information in the first servo sector and then to measure the external shock or other factors before the sampling time until the position information is sampled from the next servo sector The off-track of the head is worsened and an error may occur.

3. 발명의 해결방법의 요지3. The point of the solution of the invention

서보섹터내의 버스트 정보영역 이외에 별도의 서브-버스트를 기록하여 안정된 위치정보를 줄 수 있는 기록 매체를 제공한다.A recording medium capable of providing stable position information by recording a sub-burst in addition to a burst information area in a servo sector.

4. 발명의중요한 용도4. Important Uses of the Invention

자기디스크 기록장치에서 서브 버스트 신호를 기록한 기록매체.A recording medium on which a sub-burst signal is recorded in a magnetic disk recording apparatus.
