Abstract

PURPOSE:To reduce the processing time to a minimum, by transferring data in case when a head is positioned in a designated area, and finishing the data transfer by one rotation even in the worst case. CONSTITUTION:In case when a position where a lead gate has been opened at first is in a designated area, data is transferred without having the head sector, and as for a sector which has been omitted, the transfer is executed afterwards. According to this constitution, data can be transferred by one rotation in any case, and the rotation time can be reduced remarkably.
