Abstract:
A disk drive comprising:a disk having a disk spin axis and recording surface for storing data;a head for reading data from the recording surface;a spindle motor having a rotor;clamping means for clamping the disk so that the disk spins with the rotor;ramp-loading means;multiple-function spacer means forming part of the clamping means and forming part of the ramp-loading means;a head gimbal assembly including a flexure, a load beam having a central axis and a lift tab extending from the load beam, the flexure defining a cutout into which a tang projects, the tang having a first and a second side, the lift tab including a surface that defines a protuberance projecting away from the lift tab toward the recording surface such that the protuberance defines a protuberance depth,the spacer means having a spacer spin axis and an axially-symmetrical surface, the spacer spin axis being aligned with the disk spin axis and the axially-symmetrical surface facing away from the recording surface;the axially-symmetrical surface defining, in radial cross section, a sloped section and a recessed section adjoining the sloped section, the recessed section defining a recess depth, the recess depth not exceeding the protuberance depth;a single sided limiter that projects away from a major plane of the load beam and cooperates with the first side of the tang to provide a stop that provides a counter balancing torsion when a lifting force is applied at the protuberance; andhead-position control means for controlling a parking operation carried out while the disk and the spacer means are spinning and in which the protuberance rises adjacent the sloped section and comes to rest in the recessed section.
