Abstract:
1. A disk drive comprising: a recording medium; a head support unit that includes a head configured to record information in or reproduce the information from the recording medium, a suspension configured to support the head and rotate around an axis, and a lift tab that is connected to the suspension and inclines relative to a surface of the recording medium when the lift tab is projected onto a first plane parallel to a longitudinal direction of the lift tab; and, a ramp loading unit that includes a holding part configured to hold the lift tab outside the recording medium, and a sliding part which the lift tab elastically contacts in loading the head onto the recording medium and in unloading the head from the recording medium, wherein said sliding part when projected onto a second plane perpendicular to the axis is so shaped that a locus, which is projected onto the second plane, of a contact position at which the lift tab contacts said sliding part, as the lift tab moves on the sliding surface, shifts from a circle that is set on the second plane and has a center located at the axis and a radius corresponding to a distance on the second plane between the axis and a position at which the lift tab first contacts said sliding part, and wherein said sliding part includes an inclined part that projects at least partially above the recording medium, inclines relative to a surface of the recording medium, and partially changes an inclination angle of the inclined part.
