ABSTRACT:
A disk apparatus includes a head configured to move along a recording surface of a rotating disk; and a stabilizing member provided so as to face the disk. A facing surface of the stabilizing member facing the disk includes a curved surface whose symmetrical axis is a center generating line passing through a center of the facing surface. The head reciprocally moves along a path which is offset from the center generating line.
