ABSTRACT:
A magnetic disk storage device has a magnetic disk with a storing/reproduction region formed thereon and a head slider facing the disk surface with a plurality of parallel projections to generate an air bearing. Magnetic heads each having a head gap are provided in the projections and have an interval between head gaps of at least 1/N of the width of the whole storing/reproduction region of the disk where N is the number of heads. The device makes it feasible to increase the number of heads per disk and to shorten the seek distance without increasing the weight of the head actuator.
