Abstract
PURPOSE:To correct a misregistration with high accuracy by calculating secondarily approximately the quantity of the misregistration correction of a track by the use of position information detected from a reference track. CONSTITUTION:On a disk 5, the tracks of 0-3n in a cylinder number are disposed and the respective tracks are divided into cylinder blocks CB0-CB2 by the four reference tracks RT0-RT3 disposed at an equal interval. On the tracks RT0-RT3, servo data (a), (b) are written in the constant positions of a circumferential direction and the data (a), (b) are supplied to a control part 10 from a recording and reproducing circuit 16, thereby, the position of a head 4 is controlled. Then, the quantity of the correction of the misregistration of the track included in the respective blocks is secondarily approximately calculated by the use of the position information detected from the two tracks RT at both sides of the block CB and one track RT adjacent thereto.
