Abstract
A recording disk has a data area and a servo-burst area alternately arranged with each other in the circumferential direction of the disk. The servo-burst area has a servo-burst pattern having signal sections and non-signal sections arranged with a period .lambda. in the radial direction of the disk. The period .lambda. is expressed by .lambda.=2p.times.n/m in terms of track pitch "p" of the disk, wherein n and m are integers prime to each other provided that n/m<2.
