摘要： Reducing slider bounce within a hard disk drive. A force is received at a first material while the first material is in contact with a disk of a hard disk drive; the first material comprising a portion that is flexible in a first direction and is substantially non-flexible in a second direction. The first direction is a direction that is normal to the disk and the second direction is a direction that is parallel to a surface of the disk. The force is substantially absorbed by the portion that is flexible to reduce the force associated with interaction between the first material and the disk, thereby reducing slider bounce within the hard disk drive.

摘要： An air-bearing surface of a hard disk drive slider comprises a trailing edge wherein a magnetic transducer is coupled to the air-bearing surface. A leading edge is opposite from the trailing edge. A channel is coupled to the air-bearing surface wherein the channel comprises: a closure at a distal end proximal to the leading edge; a bottom surface; and a center of the channel approximately aligned colinear with a center of the magnetic transducer. In this configuration the channel generates significantly more negative pressure proximal to the leading edge thereby stiffening the air bearing during operation.

摘要： In a method and device for performing tilt control, a focus and a tilt controlling output is generated, and a focusing and tilt state of an optical recording/reproducing beam is controlled by determining a radial tilt value based on a differentiation of focus control values obtained at different radii of said optical disk (1). The combination of, e.g., a 3D actuator with the dz/dr tilt measurement provides the advantage that focus and tilt adjustment can be performed in the same element. Thereby, influences or measurement variations caused by environmental conditions and/or circuit characteristics can be minimized to reduce compensations requirements. Furthermore, a 3D actuator (11) with a split coil arrangement may be used to provide a three-dimensional focus adjustment. Thereby, the 3D actuator (11) can be used for feed-forward tilt compensation without offset or gain errors and without any additional sensor.

摘要： A hard disk drive with a disk base including a disk wall with a first intake, a second intake off of the first intake, an outlet and an air filter configured to receive a first airflow from the first intake and suction from a second airflow from the second intake creating negative pressure at a trapping surface of the air filter away from the outlet. At least one disk rotates to create a rotating disk surface generating airflow configured to enter the first intake to create the first airflow. A disk damper includes an enclosing wall neighboring the air filter to create a flow chamber providing a third airflow through the outlet formed of the first air flow crossing the trapping surface and the second air flow. A disk cover mounts on the disk base to encapsulate the air chamber. The disk base and disk damper are disclosed.
