ABSTRACT:
A magnetic disk drive includes a magnetic disk and a femto slider. The magnetic disk has a minimum track linear velocity of 1 to 5 m/s. In one embodiment, the magnetic disk drive includes a negative pressure type femto slider and adopts a load/unload method. A gram load “GL” of a head suspension assembly HSA is set at a value exceeding about 3 mN and smaller than about 15 mN and a pitch static attitude “PSA” (deg) and pitch stiffness “Kp” (Nm/deg) satisfy the expression ((PSA×Kp)/GL)<0.25 mm. As a result, it is possible to prevent the femto slider from assuming a meta-stable flying high state referred to as a bi-stable height. Further, by setting the pitch static attitude “PSA” at a value of larger than 0 deg, it is possible to prevent the slider from assuming a state of meta-stable contact with the magnetic disk surface referred to as semi-stable drag.
