摘要： Approaches for a fluid dynamic bearing (FDB) system for use within a hard-disk drive. A fluid dynamic bearing (FDB) system may comprise an upper conical bearing and a lower conical bearing that are both disposed along a stationary shaft on which a magnetic-recording disk is rotatably mounted. The upper conical bearing and the lower conical bearing may have different cone angles, diameters, and/or lubricants to produce a desired difference in stiffness between the first conical bearing and the second conical bearing. By adjusting characteristics of the fluid dynamic bearing (FDB) system to achieve the desired bearing stiffness ratio, the tendency for the magnetic-recording disks to experience a sustained vibration when the hard-disk drive receives a mechanical shock is reduced. By preventing the magnetic-recording disks from sustained vibration after a mechanical shock, data may be written to and read from the magnetic-recording disks with greater reliability.

摘要： Approaches for inducing a magnetic bias in a magnetic recording disk. A biasing apparatus comprises a soft magnetic material member having a shape comprising two opposing recesses, denoted an upper recess and a lower recess. A first magnet is disposed within the upper recess and a second magnet disposed within the lower recess. An air gap exists between the first magnet and the second magnet. An opening in the soft magnetic material member is sized to accommodate at least a portion of the magnetic recording disk between the first magnet and the second magnet. The magnetic field produced by both the first magnetic and the second magnetic flows (a) in the same direction, and (b) perpendicular to the plane of the magnetic recording disk. Using this approach, magnetic material on the disk, such as magnetic islands of a bit pattern media, may be erased and polarized in the same direction.

摘要： An improved disk stack assembly for a hard disk drive (HDD) includes a generally cylindrical hub with flange having a downward sloping conical flange surface. The conical flange surface is defined between a radially inner circular ridge and a radially outer circular edge. The bottom disk in the stack is in contact with the flange inner circular ridge. The disk stack assembly also includes a disk clamp with a contact surface having a contact rim that is in contact with either the radially inner portion of the top disk in the stack or a spacer ring. The clamp contact rim is located at approximately the same radial distance from the hub's central cylindrical axis as the flange circular ridge so that the clamping force is applied to the disks close to the area where the disk stack is supported on the conical flange surface.

摘要： A disk drive. The disk drive includes an acceleration sensor, a servo controller, a detection determiner, and a handling processor. The acceleration sensor has an associated resonant frequency. The servo controller is configured to perform servo control for head positioning using frequency components that are obtained by cutting off frequency components including the resonant frequency from output of the acceleration sensor. The detection determiner is configured to detect a frequency band including the resonant frequency from the output of the acceleration sensor to determine whether a magnitude of a voltage amplitude of the frequency band is outside of a specified range. The handling processor is configured to execute a corresponding handling operation if the detection determiner determines that the magnitude of the voltage amplitude of the frequency band is outside of the specified range.

摘要： A hard disk drive has a flexible cable and a flexible cable damper positioned adjacent to but separate from the flexible cable. The damper is a thin film loop with a damper patch that is completely independent of the flexible cable. The damper strip is a non-signal carrying substrate and has the constraint layer attached to it opposite the flexible cable. Both the damper and flexible cable extend in an arcuate configuration from the base to an integrated lead suspension tail extending from the actuator.

The bulk eraser includes at least three magnets and a structure magnetically coupled with the at least three magnets to produce magnetic-flux density in a gap. The gap has a first portion, a second portion and a third portion, such that a first magnet and a second magnet are disposed with opposing end poles across the first portion. The at least three magnets and the structure are configured to produce a magnetic-flux density in the second portion sufficient to erase recorded information from a portion of at least one magnetic-recording disk in a disk-stack when a hard-disk drive is inserted into the second portion. In addition, the at least three magnets and the structure are configured to direct the magnetic-flux density in a substantially radial direction of the portion of the magnetic-recording disk in the second portion.
