Abstract
An improved head adjusting disk is disclosed which is adapted to be used for adjustment of the position of a head in a mechanism such as a floppy disk drive mechanism. On the improved head adjusting disk, two head position adjusting record tracks for adjustment of the position of a head are formed such that an outer circumferential edge of one of the record tracks and an inner circumferential edge of the other record track extend along a same circumference and that one of the two record tracks is formed to extend along a portion of one n'th (where n>1 and n=2) of the circumference while the other record track is formed to extend along the remaining (1-1/n) portion of the circumference, whereby individual signals reproduced from the two head position adjusting record tracks can be distinguished from each other by difference in duration thereof.
