<p>Disclosed is a magnetic disk device provided with a magnetic recording medium (2), a head actuator (3) which has a magnetic head (31), a ramp (4), and three first deflection limiting members (5a, 5b, 5c). The three first deflection limiting members (5a, 5b, 5c) are arranged along the circumferential direction of the magnetic recording medium (2) so as to face part of the outer circumferential edge of the magnetic recording medium (2) at both surface sides thereof without making axial contact, and the three first deflection limiting members (5a, 5b, 5c) are constructed so as to be capable of suppressing deflection that occurs in the magnetic recording medium (2) due to external force.</p> |
