Abstract

본 발명은 정보기억용 디스크상에서 현재 트랙의 서보영역에 기록된 트랙번호를 판독하고, 그 서보영역의 위치에러신호로부터 트랙추종정보를 산출하여 목표트랙정보를 산출하며, 해당트랙의 인덱스를 기준으로 현재의 섹터번호와 목표트랙섹터번호를 산출하고, 해당트랙 및 섹터를 억세스하는 헤드번호를 구하는 단계로 구성된 정보 기억용 디스크의 섹터지정 및 구동방법에 관한 것이다.The present invention reads the track number recorded in the servo area of the current track on the information storage disk, calculates the track tracking information from the position error signal of the servo area, calculates the target track information, and calculates the target track information based on the index of the track. A sector designation and driving method of an information storage disk comprising the steps of calculating a current sector number and a target track sector number and obtaining a head number for accessing the track and sector.
